Why Calories Remain Pivotal For Fat Loss

FitGreyStrong fact: Weight gain occurs when total caloric daily consumption exceeds total daily energy expenditure. To achieve weight or fat loss there must be an energy or caloric deficit. Over 80 years of scientific research has confirmed this to be fact.

FitGreyStrong Advice: Don’t believe the hype. Food quality is a must and essential to good health. However, weight or fat loss will not be realised no matter how good your diet is unless an energy deficit exists. Increased total physical activity during all waking hours and an energy-deficit diet that is wholesome, natural, minimally-processed and nutrient-dense will provide a significant opportunity for weight loss to be achieved.

I’m going to make a confession. I have laboured over the last month to write this blog. I’ve spent hour upon hour trying my best to explain what I think is a simple concept. The strangest thing is the evidence published so far is conclusive but with so much shit floating around anyone looking to lose a few kilo’s in the New Year is faced with a major challenge. What info is good and what is bad? How does one decipher what advice to act on and what advice to send to the computer’s recycle bin?

As I explained recently the media and ‘rogue’ researchers have, in some ways, muddied the weight loss debate by promoting the idea that exercise doesn’t help (see here). There are many examples of the media misleading consumers by sensationalising material that has been poorly researched, lacks objectivity and obfuscates the facts.

Ironically, it is this type of questionable and controversial material that gains the most traction with the public. The confusion created by such reporting has had a truly dreadful impact on the public’s perception regarding the role of exercise for weight loss. Many health care professionals working in the field have also raised serious concerns about this too because there is the feeling that some people may simply avoid physical activity altogether.

Notwithstanding that compensatory mechanisms mitigate the efficacy of exercise in some people (see here), widespread consensus remains elusive regarding the very basic underpinnings of weight loss. It seems incredible in fact that in the year 2016 vigorous debate and disagreement continues to swirl. However, I believe that the writing was on the wall when Generation X’s were still kids. There was sufficient scientific research carried out from the 1930s to the 1980s to put to bed and move on from some of the most hotly contested questions relevant to weight loss. The two questions which continue to inspire fierce debate are:

1. Do calories really matter?

2. Is weight loss simply a matter of expending more energy than you consume?

Before outlining what the specific focus of this blog is I need to digress. I want to make clear that it is not my intention here to assess whether manipulating the macronutrient makeup of the diet – e.g. high fat versus high carb diets – yields superior benefits on metabolic outcomes such as fasting blood glucose or lipid profile. Of course, this is a very important question to address but I’ll have bitten off way more than I can chew to do this justice, so I’ll come back to this another time.

The only thing I will say is that the actual published research is mixed. Three meta-analyses and systematic reviews have been completed over the last 18 months assessing whether metabolic outcomes are affected by manipulating macronutrient composition. Two of the these (see here and here) concluded that there were no differences on metabolic outcomes when the protein, carbohydrate and fat composition of the diet was varied; whilst the other paper (see here) suggested the opposite stating that dietary manipulation did alter metabolic outcomes.

Ok, let’s get back to what the focus of this blog is then.

inactivity and fat gain — Is obesity a disease?

The aim of the following is to shine a spotlight on and explore the mechanistic aspect of weight loss. You may be wondering…………. what the bloody hell does that mean? What I mean by ‘mechanistic’ is the basic physiological state required – in our species, Homo sapiens – to bring about weight loss.

To state this as simply as possible, when it comes to weight loss the single most important factor from a physiological perspective is that there exists an energy or caloric deficit. Eighty-five years of scientific research and investigation has demonstrated without equivocation that for weight loss to occur an energy deficit must exist. Total daily energy expenditure has to exceed total daily energy intake for any reduction in body mass to occur or vice versa for any increase to occur. Regardless of one’s age, race or gender this holds true. This really is the only conclusion you can draw if you actually read the studies that have been published in reputable peer-reviewed medical journals relevant to this area (see here).

Now some of you may disagree with me on this and you are not alone. Unfortunately, in my view, there are a number of dissenting voices from a variety of quarters that simply don’t believe this to be true. They passionately dispute this and contend that the total energy provided by the diet matters very little. What really counts is the metabolic effect food has on our body. An example of this type of thinking can be found here.

Supporters of such thinking, decouple weight loss and calories. They propose that the “metabolic propensity” to increase and store fat in the adipose cells is driven primarily by the quality of the foodstuffs ingested and the proportion of protein, carbohydrates and fat in the diet. “A calorie is not a calorie” because different foods of different qualities have different effects on our digestion, hormones, biochemistry, metabolism, thermogenesis, physiology and associated internal feedback loops.

Whilst the total energy or calorie content of food matters, what is significantly more important is the metabolic effect that food has on our body. All calories are not created equal, therefore, with the quality and type of food choices made and the subsequent metabolic effect that such choices have on our body ultimately determining if fat loss is successful or not.

The most significant and telling problem with this line of thinking is that there are virtually no respected and acknowledged researchers who believe it. I see this as a telltale sign that the dissenters are simply barking up the wrong tree. Virtually all leading obesity experts worldwide concur that unless there is an energy deficit, decreases to weight or fat mass are not possible irrespective of how good the diet is. The question needs to be asked, why is this the case?

FitGreyStrong’s take-home message to you up to this point is:

Unless you expend more than you take-in you ain’t going to see any changes to your weight or fat.

Weight training for fat loss — Resistance and weight training shows great promise to maximise fat loss

There exists consensus amongst nearly all scientists because of the following. Research undertaken with participants confined to an in-patient hospital setting or in facilities known as metabolic units are currently the most accurate way to scientifically determine the specific energy requirements needed for weight change. Such studies are usually expensive because they are very resource and equipment intensive. However, what they allow researchers to do is measure what is being consumed (energy in) and what is being expended (energy out) quite precisely – or at least, a lot more precisely than studies that involve free-living subjects.

In brief, the methodology of such studies looks something like this:

For the duration of the trial subjects have to remain in the hospital or unit.
Participants of these studies are allocated and given all consumables (food and drink) for the duration of the intervention.
The caloric content of what is consumed is a known entity and has been prepared and accurately measured.
The macronutrient percentages of the diet for protein, carbs and fat has been determined.
Physical activity is closely monitored, measured and accounted for.
Resting energy expenditure (REE) and total daily energy expenditure (TDEE) is estimated as accurately as possible based on the equipment utilised and methods employed in the study.

With energy intake and energy expenditure measured as close to actual as possible, investigators can now establish whether the prerequisite for weight loss is an energy deficit. Over the last 80 years or so there have been over 20 studies carried out that have assessed the effect of calorie and macronutrient manipulation on weight loss whilst in the strict confines of hospital or metabolic unit.

Evaluation of such research has shown that no major differences have been found for weight or fat loss when diets of different macronutrient composition but with the same amount of energy (i.e. isoenergetic diets) were compared. Results from these studies show beyond dispute that the key determinant for decreased weight is a caloric or energy deficit, not diet composition.

To look at the evidence another way, not one of these trials – not even one – has ever demonstrated an increase in body weight when daily energy intake is less than daily energy expenditure. Likewise, no such study has ever shown a decrease in body weight when daily energy intake exceeds daily energy expenditure. This remains so irrespective of the macronutrient breakdown.

To give you a taste of the studies that have incorporated some of the methods referred to above, let’s take a quick look at a few of these:

Study 1 – Graves and colleagues conducted a randomized trial comparing an energy-restricted high-protein versus high-carbohydrate, low-fat diet in the morbidly obese which was published in the Obesity Journal (see here). Eighty-eight obese participants (mean age, 46.7; mean BMI, 45.6 kg m squared) were enrolled in a 3-week inpatient and 48-week outpatient treatment. The study was novel in that it included cognitive behaviour therapy in the treatment. All subjects consumed a restricted diet (1,200 kcal/day for women, 1,500 kcal/day for men; 20% energy from fat, <10% saturated fat). The high-protein diet derived 34% energy from proteins, 46% from carbohydrates; the high carb diet derived 17% from proteins, 64% from carbohydrates. The primary outcome was 1-year percent weight loss and secondary outcomes were attrition rates, changes in cardiovascular risk factors and psychological profile. The three week in-patient period closely monitored and provided all food with the total energy content and macronutrient composition known.

No difference in BMI or weight reduction was detected for this period between each diet.

The authors concluded (pg.1774) that:

“the relative carbohydrate and protein content of the diet, when combined with intensive CBT, does not significantly affect attrition rate, weight loss and psychosocial outcome in patients with severe obesity”.

Study 2 – Golay and co-workers compared diets equally low in energy (1000 kcal) but widely different in relative amounts of fat and carbs on body weight reduction in 43 obese adults during a 6-week period of hospitalisation (see here). The diets were composed of 32% protein, 15% carb and 53% fat versus 29% protein, 45% carb and 26% fat. The first diet could be described quite well as a low-carb, high-fat diet and the second diet as a more balanced diet. After 6 weeks no significant differences were seen for weight loss, fat loss or waist-to-hip circumference. Energy intake, not nutrient composition, determined weight loss in response to low-energy diets.

Study 3 – Leibel and co-workers established in 1992 that even during very wide variations in the fat-to-carbohydrate ratio (fat energy varied from 0% to 70% of total intake) there was no significant variation in energy need and changes in body weight (see here). Sixteen human subjects were confined to a metabolic ward for an average of 33 days and fed precisely known liquid diets with protein derived from milk and fat varied from different amounts of corn oil. Total energy intake, not diet composition was once again the key determinant in modulating energy balance.

I could continue and summarise the other studies published but the overall findings are much the same as that described above. For a more extensive review of these type of studies please see here.

Confusion around this topic, I think, has been created by other research and weight loss trials that don’t take place in the confines of a hospital or metabolic unit, but rather use free-living subjects. These studies cannot accurately quantify energy intake and expenditure and they are hence plagued by problems.

Firstly, participants often have to record or attempt to recall what they ate and drank. It probably doesn’t surprise you then that this has been shown to be notoriously inaccurate. Even those studies that provide free-living subjects with their allotment of food and drink can’t completely prevent or control for individuals eating or not eating the food on their assigned ‘menu’. Secondly, energy expenditure is estimated via physical activity logs, diaries, pedometers or fancy equipment like activPAL (see here). Consequently, energy expenditure can often be under- or over-estimated so such data can be terrible misleading. To state the obvious, deriving definitive results and conclusions from these types of studies is going to be challenging.

In spite of the caveats mentioned above, the results from the many studies using free-living subjects concurs with the hospitalisation and metabolic unit studies. Two meta-analyses and systematic reviews published in 2014 and 2015 concluded the same thing:

“Both types of macronutrient-centered weight loss diets produced weight loss. Manipulation of macronutrient composition of weight loss diets does not appear to be associated with significantly different weight loss or metabolic outcomes.”

The massive 2014 review by Naude and colleagues (see here) assessed 228 studies making it one of the largest meta-analyses and systematic reviews available. Provided one reads and reviews such research with an objective and impartial mind it is implausible to reach any other conclusion.

A final comment: The one thing that I believe provides the biggest hint that total calories are indeed fundamental to weight loss is something that is noticeable in the methodology of the more scientifically robust studies. Of the research that has taken place in a hospital or metabolic unit setting there is one key characteristic that most of these studies determine before proceeding to the weight loss phase of the trial. Can you guess what it is? Researchers establish energy requirements (i.e. total daily caloric intake) for weight maintenance over a period of 1 to 2 weeks (see here). If for arguments sake, calories were not important for inducing weight loss, then establishing energy requirements for weight maintenance in these studies would be a pointless exercise.

Before I finish up I need to make some clarifying comments.

1. Those that make the claim that calories are not important in relation to the obesity problem or when trying to decrease body fat are doing, I think, either one of two things. They are ignoring the data produced from hospital/metabolic unit-based studies and/or they are misinterpreting and taking at face value the results of research conducted with free-living subjects.

2. There will be those that read this and conclude that what I am advocating or all that I think matters is calories, with diet quality just a cursory concern. I can hear some of you saying right now “….but surely 2500 calories of jelly beans or junk food is different to 2500 calories of atlantic salmon, walnuts, broccoli and berries.” Really? Well, yes, of course it is, thanks for pointing that out. A diet consisting of wholesome, natural, minimally processed and nutrient-dense foods is paramount to ensuring good health. I should state now that I am not suggesting for one moment that the quality of the diet is not important.

Fruits and vegetables are essential to health — Food quality is key for health and weight management

3. Irrespective of how good a diet is in optimising the metabolic effect on your body, the fact remains nonetheless that it is still possible to gain weight eating a wholesome, natural, minimally processed and nutrient-dense diet. It is probably more difficult to do so, but regardless, you cannot escape the fact that you have to be in a consistent calorie deficit to lose fat or a chronic caloric surplus to gain fat.

How To Do A Standard Deadlift

January 2, 2016 seanwilso Leave a comment

Share this:

The standard Deadlift is one of the best exercises available to develop many of the largest and strongest muscles in the body and is essential to any resistance or strength training program. It is one of the few standard weight lifting exercises in which the start of the movement begins with ‘dead’ weight. The Deadlift is a fantastic exercise for anybody over 40, provided it is performed correctly with good technique and with proper progression. It is a compound movement that stimulates many different muscle groups and provides excellent weight-bearing loads to several critical joints in our body. For more information on the basics of the Deadlift please see here.

How to do the Deadlift and key things to remember

Standard Deadlift: This exercise can be broken down into three parts.

The setup;
The pull or drive;
The lockout.

The Setup:

During the set-up the gluteus maximus and minimus (glutes/buttocks), quadriceps muscle group (thigh), all muscles of the hamstring group and the triceps surae (calf) will be eccentrically loaded.
The erector spinae muscles (lower back) and assisting core muscles will contract isometrically to stabilise the spine.
The bar should be resting against the lower tibia or shin bone.
To maximise recruitment of the lower body musculature – for general purposes and sports specific training – I would suggest that there be sufficient knee flexion at set-up so that both hip and knee extensors are both major contributors during the Deadlift. Too many do this exercise with too little knee flexion thereby making it predominantly a hip dominant movement rather than a hip and quad combined movement. This advice is not applicable to powerlifting with less knee flexion used for competition.
Hip-to-shoulder body angle in relation to the floor (or horizontal) should be somewhere between 20° to 40°. This can be varied depending on the load desired on the hip dominant or quad dominant muscles. Generally speaking, reducing this angle will place more stress or load on the hip dominant muscles (glutes) by increasing the leverage and length of these muscles.
The bar can be gripped either between or on the outside of the legs. Most standard Deadlifts however will have the bar gripped on the outside of the legs.
Hand grip can be pronated (palms facing legs) or an alternative grip with one hand pronated and one supinated (palm facing away from body) being also popular. For heavier lifts most will use the latter grip mentioned above as this will synergistically create better upper body stability and linkage to the lower limbs during the move.
The scapulae need to be retracted or depressed with the shoulders held firmly in place so that the load is distributed via the lats and erectors. The idea is that the linkage between where the hands grip the bar and where the feet contact the floor remains at greatest tension so that the forces generated can be translated efficiently.

Drive:

The highest amount of force is produced during the drive phase.
The key movement concept to think about when commencing the Deadlift is not to “push up” but rather to “push away”. So when you initiate the movement imagine you are pushing the floor away from your feet with the body virtually staying in place.
During this initial drive phase which finishes just around the knee, the upper body angle should stay the same.
The movement of the bar from the floor to the knees should be mainly achieved by the recruitment of the glutes, quads and hamstrings.
The spinal column should stay straight. To the naked eye from an observer, the spinal curves at lumber, thoracic and cervical sections should look the same or remain neutral as they would appear if you were standing erect.
From the lateral view, the knees should approximately fall over the feet and as the drive phase is carried out the knees will slightly move behind the feet.
By driving through the floor with flat feet and unhinging at the hips and knees, the bar should travel very close to or in fact scrap the tibia or shin bone all the way up to the knee. You may require some tights, long socks or something to cover the lower legs as once the technique is mastered (if you are using an Olympic bar with a roughed surface) you may otherwise take skin off and possibly bleed. This is a good sign that the bar is travelling along the correct path if all else is being performed well.
Safety for this exercise is primarily based on ensuring that correct technique is developed before progressing the weight up. If sufficient knee flexion is utilised for the standard Deadlift with the drive phase being completed with the upper body angle constant with neutral spinal alignment held, lumbar load and integrity is maintained.
Performing the valsalva manoeuvre (see here) also assists in stabilising the bodily structures and core during the whole femoral-lumbopelvic movement.

Lockout:

The lockout phase for FitGreyStrong followers commences from the knees to the standing upright position.
Following the drive from the floor to the knees, the upper body angle now changes from the 20° to 40° that was held for the drive phase.
From this point you are now trying to stand upright. To do this, once the bar has cleared the patella or is just above the knees, driving or thrusting the hips forward whilst attempting to stand upright is the movement concept to be thinking. This is where the glutes, hamstrings and erectors are required to work in unison to complete the Deadlift.
There is still some knee extension left to complete so the quads will still be required to contract forcefully in sync with the primary contraction of the glutes, hamstrings and erectors to complete the entire movement.
The core musculature (abs, obliques, TA) and supportive muscle such as the lats are needed to be held tight and strong so that the prime movers can work optimally.
The bar should finish resting fully against the upper quads with the thighs and hips fully extended, arms extended, shoulders back and head in normal position and eyes looking forward.

Lowering the weight:

Lowering from the lockout position does not have to but can mirror the concentric stand-up movement of the Deadlift. This is an individual’s preference.
FitGreyStrong’s recommendation would be to slide the bar down against the quads, over the knees and down the tibia/shin bone until you can return it to the floor.
The spinal alignment and maintenance of correct form as outlined above would still be imperative and will, in general, minimise risk of injury.
Knee and hip flexion would be gradually increased as one lowers the bar toward the ground.

Final comments:

The standard Deadlift is one of the very best resistive-based exercises available in the gym setting for anybody of any level of fitness or anyone of any sporting background wanting to increase full-body strength for performance enhancement. If you haven’t tried this exercise before make this one of your top priorities to learn and master; it will pay huge dividends irrespective of what you are trying to achieve.

The Unspoken Truth: Why People Struggle To Lose Weight

November 24, 2015 seanwilso Leave a comment

Share this:

In my article titled “It can’t possibly be true, can it?” I questioned whether there was any foundation to the claim that inactivity is not a chief cause obesity and provided scientific evidence suggesting otherwise. Today I will try explain to you what the bottom-line is as to why exercise doesn’t work for everybody trying to lose weight. One thing I have noticed is that there isn’t enough time or effort – either in the media or on the net – dedicated to informing the public about why exercise does not work for some people and what can be done about.

Exercise has been successfully applied as an essential ingredient of many weight loss programs. By increasing total daily energy expenditure, creating a caloric deficit state is theoretically, at least, more likely. It naturally follows that the weight loss achieved will be correlated to the magnitude of the energy deficit created. In practice however this does not always happen. In fact, there are a number of studies and anecdotal evidence that show a significant proportion of exercisers eating an ad libitum diet (possibly as high as 50%) do not achieve the weight loss expected with as many as 15% actually gaining weight. These individuals are often referred to as ‘non–responders‘. Those on the other hand that do achieve weight loss from exercise are referred to as ‘responders‘. The question is, how is this possible and are there any practical solutions?

exercise doesn't work for everybody trying to lose weight — Energy compensation and exercise-induced fat loss

People respond differently to exercise:

Non-responders vs responders

These differences in response to exercise include:

Non-responders increase whilst responders decrease, total daily energy intake (all the food and drinks you consume on a daily basis).
Some of these differences apparently occur unbeknownst to the exerciser so there is some sort of compensation going on to offset the extra energy expended from exercise.
Non-responders increase their consumption of fat.
Non-responders experience much greater subjective sensations of fasted hunger (upon waking) and hunger across the day compared to responders.
Non-responders demonstrate an increased whereas responders show a decreased, desire to eat.
Non-responders satisfaction or feelings of fullness from meals is significantly reduced whilst there are no changes in responders.
Behavioural compensatory adjustments to exercise training in overweight women showed the loss of weight/fat mass or lack thereof, was attributable to an increase or decrease in spontaneous physical activity, respectively.
Resting metabolic rate may be reduced in non-responders but not in responders.

Appetite is controlled by the brain — Brain function and weight control is poorly understood

If you are struggling to lose weight after starting an exercise regimen then you could be classified as a non-responder and should consider the following:

If possible, have some measurements taken by a knowledgeable professional that includes girths (such as hips, waist, thighs etc) and skinfolds where the subcutaneous fat can be approximately measured by calipers. By doing this you will be able to work out more precisely what changes are actually taking place. This is pretty important because some ‘non-responders’ will lose a considerable amount of fat but total weight loss may be only slight or actually increase (see King et al 2008). This will affect roughly 10% of exercisers that are trying to lose weight but these body composition changes are in fact desirable and favourable.
Monitor energy intake more closely and consider recording actual food and beverage intakes so you can keep tabs on this as you go. Given that ad libitum diets don’t seem to work too well for non-responders, recording your intake is a good place to start. Assuringly, research shows that those that diarise what they are eating and drinking are much more successful at weight loss and weight management compared to those that don’t, so start recording.
Recognise that if you keep accurate records of these things and create an energy deficit – the research that has been conducted in metabolic-ward studies suggests – that weight loss is highly probable. Based on an account of energy intake and energy expenditure, if the creation of an energy deficit does not elicit any change in body composition, it is likely that there has been an over-estimation of energy expenditure or an under-estimation of energy intake, or a combination of both. However, this now allows subtle changes to be made to energy expenditure or intake so that body fat mass reduction can be realised (see here and here for great discussions on the crucial role calories play when it comes to fat loss or fat gain).
Ensure that your exercise program includes some resistance or weight training. The response to exercise of non-responders as outlined above is related specifically to 1-2 hours of aerobic exercise (i.e. walking, running, cycling etc). You may ironically achieve better weight loss if you back off the aerobic exercise but place a bit more emphasis on weight training or resistance-type exercise. Some research has shown that appetite is suppressed more so with resistance versus aerobic exercise and it is the changes of increased appetite in non-responders that presents a major problem when attempting to bring about sustainable weight loss. With respect to adults who are overweight or obese, Drenowatz & colleagues clearly demonstrated that resistance exercise but not aerobic exercise reduced fat mass.

Weight training and aging — Resistance training is very effective to facilitate fat loss

This form of activity also substantially reduces the risk of losing LBM (lean body mass = muscle tissue) in older adults (see Villareal et al). It is very common to see exercisers lose significant amounts of LBM when only aerobic exercise is undertaken while in an energy deficit state.
The loss of LBM is not desirable for 2 key reasons. Firstly, functional physical capacity could be affected in both the short and long term (see Villreal et al). Secondly, resting metabolic rate will be reduced thereby making weight loss more difficult and weight regain more likely (see here for further discussion).
“Don’t put the cart before the horse.” By that I mean, the quality of what you decide to eat will have a massive impact on your success. A caloric deficit is the goal but it should be achieved with a diet consisting of wholesome, natural, minimally processed and nutrient-dense foods. Not only is this essential to weight loss success but more importantly generating good health.

To lose weight you need to expend more than you eat — No caloric deficit = no fat loss

To combat increased subjective sensations of hunger, then, as a start please make sure that the diet is high in a variety of vegetables, has several serves of fruit each day, contains sufficient and varied sources of protein and includes things like nuts, seeds and oils. This is pretty commonsense stuff but you need to put into practice what actually works. The make-up or quality of the diet appears to impact on subsequent appetite, sensations of hunger and feelings of fullness, so anything that assists in keeping the physiological drives to eat at bay are only going to be helpful (see Blundell et al).
