The Latest On Weight Loss, According To Science And My Observations

As fate would have it, quite a few interesting articles regarding research related to weight loss have come out in the past few weeks since I posted my "why we  should probably all stop offering weight loss coaching" article of a few weeks ago.

Now, unfortunately the fact remains that long term success with weight loss goals is a statistically unlikely outcome. Therefore I suggest that anyone making any promises about weight loss with the inference of "guaranteed" results is at best overly optimistic or at worst a damn dirty liar. Certainly though there are people out there who've lost weight and kept it off... so if you have a weight loss goal, and let's quantify that and say you have a permanent weight loss goal, what you probably want to be concerned with is figuring out where your best chances of success lie, and with avoiding the mistakes that all the unsuccessful people are making.

First let's talk about exercise. You should be doing some resistance training.

• Resistance Training Combined With Diet Decreases Body Fat While Preserving Lean Mass Independent of Resting Metabolic Rate: A Randomized Trial.

This is probably not news to anyone who has followed my various social mediums for more than a few minutes by now.

Resistance training is one of the best things you can do for your health, whether you have a weight related goal or not. Reiterating about 5000 of my previous entries though, and this is important so make sure you're paying attention this time, the purpose of resistance training is a lot less to do with "burning calories" and a lot more to do with inspiring your body to take up and put more energy and resources to use in supporting lean mass, ideally at the expense of fat mass.

So it's not just that you expend energy while training (although you do, and that's good) but that your body has something productive to do with the balance of energy that remains.

And by the way for what it's worth, it absolutely IS possible to gain lean mass at the expense of fat mass, especially for beginners but also even in more experienced athletes and enthusiasts.

Q: What's a good resistance training program for a client who wants to lose weight?

Exercise selection and variations in programming obviously will vary between individuals, but generally speaking the best resistance training program for a client who wants to lose weight is the same program that you would give her if she didn't want to lose weight... subject to her levels of confidence and proficiency at exercise.

Where most people with a "weight loss" focus will screw this up is by messing with the program, adding stuff in, leaving rest periods out, performing the whole routine as a super set or a circuit, and so on, with the idea that they "need to burn more calories to lose weight". So there's an obvious mistake you should decide right now that you will resist the urge to commit in future.

A couple of related links on this point:

• Effects of BodyPump and resistance training with and without a personal trainer on muscle strength and body composition in overweight and obese women.

Just a little more on the many benefits of strength / resistance training:

• A Systematic Review of the Effects of Resistance Training on Body Image.
• The effects of strength training on cognitive performance in elderly women.
• Association of Resistance Exercise, Independent of and Combined With Aerobic Exercise, With the Incidence of Metabolic Syndrome.

I may have digressed a little so peruse those additional links at your leisure. The first one may be especially pertinent to many of the people reading this entry.

Back to the main point as per the included image above, diet is key but resistance training will facilitate the best and most consistent results.

Paradox: Diet is the key, but "diets" don't work.

Diet is a contentious topic.

On the one side of the fence you have the people who insist upon some variation of the "all they have to do is stop eating crap food, cut out carbs, cut out grains, and eat clean" theme, and on the other side of the fence you have the people who insist "all that matters is that they are in caloric deficit". However, according to the International Journal Of Obesity, “it is now well established that the more people engage in dieting, the more they gain weight in the long-term”. So with one or two very rare, very notable exceptions, both camps are full of idiots.

Now I covered an abundance of evidence in this weight loss bullshit busting master post (not to mention all the other master posts), a while back... so rather than being redundant and repeat myself again and again, let's skip to the new stuff. Suffice it to say though, it's NOT about "clean eating" and it IS about "calories in, calories out", but it is NOT about "less and less and less calories in, more and more and more calories out".

At a certain point with such approaches... whether by deliberate caloric restriction or by omission of energy dense food choices to the effect of caloric restriction... all you are doing is training the body to manage the workload, rather than to actually benefit from training. It may be more accurate to say that you are training the body to require that level of workload (expenditure) at that level of restriction (intake) just to maintain a heavier and fatter condition, and if those levels are unsustainable then weight gain / regain will occur. As would appear to fit with the observation quoted earlier.

Again though, this has been a contentious topic. The majority of the "calories in calories out" crowd until very recently have insisted that there is no way for the body to adapt to prolonged and excessive levels of caloric restriction so as to preclude weight loss. Rather they would insist "if people are in deficit they see fat loss, if they're not seeing fat loss they're lying to you about how much they eat". 

Now since the Biggest Loser Study a year or so back, people in that camp have begrudgingly admitted that the body WILL adapt to prolonged calorie deficit and this WILL preclude further fat loss, but have continued to insist that the answer to this is simply to restrict even further into deficit and/or increase expenditure further with additional exercise & activity. I did mention that I think most of them are complete fucking idiots, didn't I?

Anyway. Increasingly, more and more evidence suggests that while fat loss IS dependant upon being in caloric deficit, we must work to appropriate levels of deficit where an expectation of adherence is not unreasonable, and where we are still providing sufficient energy and resources to benefit from training, and we must not restrict indefinitely but rather adopt a strategy of working at periods closer to metabolic capacity and at periods working from a greater level of deficit.

So, really that's almost exactly what I have been talking about for years... isn't it? 

Here are some links to relevant evidence:

• Intermittent energy restriction improves weight loss efficiency in obese men: the MATADOR study.
  Greater weight and fat loss was achieved with intermittent ER. Interrupting ER with energy balance ‘rest periods’ may reduce compensatory metabolic responses and, in turn, improve weight loss efficiency.
• Calorie Shifting (Refeeding) for Max. Fat Loss Has Overweight Women Lose 8kg of Pure Fat in 42 Days - 2.6x More Than Calories In vs. Out Predicts.
• Cyclic Dieting Drops 12.3 vs. 8kg of Body Fat in 16 Weeks, Maintains REE During + Fat Loss Post Dieting.
• The High Protein group consumed significantly more total calories and protein compared to the NP group and experienced a greater decrease in fat mass and % body fat. (Refer graphic below)
• Homeostatic regulation of body weight is more effective when energy intake and expenditure are both high.

Now... the approaches in each of those studies are different, but collectively in my opinion they more than sufficiently refute the "further into deficit (aka less calories in) always results in greater fat loss" doctrine as pushed by far too many halfwitted CI/CO & IIFYM proponents. 

Other contributing factors:

• Irregular meal-pattern effects on energy expenditure, metabolism, and appetite regulation.
• Time-restricted feeding study shows promise in helping people shed body fat.
• The influence of gut bacteria on appetite and weight.

Practical application of this information:

As coaches, as overweight or obese people, and even as fitness enthusiasts of non excessive weights, we need to be aware of and appreciate the paradoxical nature of things. To wit; an energy deficit is required to facilitate fat loss, but prolonged and excessive levels of energy deficit are associated with a higher body fat percentage in athletes and with greater long term weight gain in the overweight and obese. It is similarly ironic that when changes in body weight are seen as the most (or only) important outcome of an exercise program, we tend to adopt less effective approaches due to being overly concerned with "burning calories" and we are less inclined to pursue and appreciate the many benefits of productive activity.

Regardless of whether we are overweight and obese people or whether we are relatively lean and more active people, we need to move away from a "dieting" mentality where we glorify or consider necessary the arbitrary restriction of food choices, or over restriction of energy intake. We need to cease associating the suppression or ignoring of our bodies' hunger signals with discipline, will power or other strength of character and these virtues with the attainment and maintenance of a lean and healthy physical condition.

Rather, we should take an interest in learning and practicing a productive and beneficial approach to exercise and activity. We should practice regular, consistent, structured and varied eating habits to an appropriate but not excessive total energy intake. As per the links above, there may be some evidence to support the practice of eating more earlier in the day and less later on... but I would suggest whatever meal and snack schedule each individual finds convenient, appealing and sustainable to achieve "appropriate but not excessive total energy intake" by default without being too concerned about occasional divergences.

This could simply be described as practicing self care and healthy habits, and this alone should prove conducive to better physical and emotional health as well as a leaner condition, whether actual weight changes occur or otherwise.

For those who are enthusiastic to work more strategically to maximise their potential to see the most significant and sustainable results, the process should involve periods of working closer to a "maximal" level of intake representing metabolic capacity, and periods of working to a merely "adequate" level of intake which is at a significant deficit, but still suitable to a reasonable expectation of adherence, and to reap the benefits of training without resulting in comprised metabolic rate.

Why I stopped coaching weight loss for a few years there.

This was originally posted under another title on the old blog. A title that is no longer accurate since I'm now offering weight loss strategies again. Read on and it will all make sense, hopefully.

This is more complicated than you probably think.

People tend to want everything broken down into just one slogan or soundbite that either suits their biases or that they find easy to argue against. The reality is, there are a lot of angles to cover here. I'll do my best to cover them all within a reasonable word count, but I make no promises on that last part.

Now that that's out of the way, let's get started.

For reasons that will hopefully become apparent, I'm actually going to start with the conclusion, and the conclusion is actually a paragraph borrowed from something I posted on instagram the other day, as follows:

More than ever, the longer I do this and the more people I work with as a professional coach, the more I truly believe that our focus needs to be on simply enjoying the physical challenge of productive training, and enjoying the intellectual challenge of working to a productive fueling strategy, as well as assessing your physiological and psychological responses to each as you learn to do more of what keeps you strong, healthy & happy, and to reject whatever doesn't.

That sounds great, but what's the problem with wanting to lose weight?

Well I'm glad you asked. First of all though, that headline at the top of the page doesn't translate to "I don't want to coach fat people" or anything silly like that. Also, I always object to anything that gives anyone a message to the tune of "you might as well not bother trying, just accept that where you are is where you're supposed to be", so that's definitely not my point either.

Obviously I've helped people to lose weight successfully in the past. Clients, other people who follow my pages and put the pieces together for themselves. Some with medical conditions such as autoimmune diseases. Some who got on top of a restrict, binge & purge type eating disorder and lost weight. Some who rather generously credit me with facilitating a "life saving" level of weight loss.

A handful of fast facts about diets and weight loss:

1. All diets work for the same reason; they create a caloric deficit.
   Whether people are aware of the amount of calories or whether due to restriction of food choices, any changes in dietary habits that result in weight loss infer a caloric deficit.
2. Different named diets, low carb approaches, balanced approaches... when the energy and protein provision is matched, the clinical evidence suggests there is little if any difference in the results of different approaches. So there is not just "one correct" or "one best" set of eating habits we should all adopt.
3. Regardless, the statistics are that over the long term there is no approach that has a high success rate. People tend to regain the weight.
4. In fact, according to the International Journal Of Obesity; "it is now well established that the more people engage in dieting, the more they gain weight in the long-term."

So, what is the problem then?

Well that depends.

In theory, you make changes in dietary habits resulting in a caloric deficit. You lose weight, and so long as you do not revert back to habits resulting in a caloric surplus you should not regain the weight. Therefore the simple explanation is that the problem is down to continuance of adherence. Or so it would seem.

As an example, here's how it is supposed to work, and for that matter actually does work.

Imagine I have a new personal training client who is a younger woman and let's say 5, 10 or 15kg overweight due to not being in the habit of being active, and perhaps in the habit of over indulging a little too often. As a competent and responsible trainer, I get her started with a decent, strength based training program, and the appropriate energy targets at a suitable level of deficit and with a reasonable margin for error. If she follows my instructions with some level of consistency she'll certainly lose weight as she develops a more athletic condition.

Assuming she then maintains her interest in training and does not revert to an excessive energy intake, she should not regain any weight. That's how it works in theory anyway. I want to move on but first let's just acknowledge that what I've described is not really a "weight loss approach" the way most people would go about it.

So, whether it is working to a caloric deficit, whether it is sticking to this particular diet and this particular set of foods... if the people continue to do it, it would continue to work, right? You'd like to think so. So why don't people just keep doing it?

Reasons for non-continuance of adherence:

There could be any number of reasons and I'm not forgetting that mere complacency or even delusion are two of them, but it would be a flagrant cop-out to pretend that those are the only reasons and therefore absolve trainers & health coaches from their obligation to provide approaches that are feasible and efficacious over the long haul.

In simpler terms, I'm asking you just humour me and consider entertaining the mere possibility that people sometimes lose motivation because the approach has stopped producing results, or simply because the approach is impractical and any expectation of continued, long term adherence was entirely unreasonable.

Weight loss dieting tends to be of an extreme variety, either with strict low calories, strict food exclusions, or both. Strict adherence would prohibit ever going out to eat socially, visiting your parents for a home cooked meal, having a takeaway night or ordering home delivery. These approaches tend to be temporary by design, and as discussed, the long term consequence is greater weight gain.

With that in mind and getting back to my hypothetical client we described earlier, if we focus on developing an interest in a productive approach to training, we can expect weight loss. However if we focus on weight loss and my instruction is a low carb, low cal, clean eating style of extreme and restrictive diet, as well as high intensity activity "to burn calories"... any expectation of continued long term adherence is overly optimistic at best, any weight loss is temporary at best, and the long term consequence would be weight gain, a worsened relationship with food, and likely a decrease in enthusiasm for exercise as well.

In the case of a second new client of a higher and more excessive weight, it is very likely that their current weight is actually the consequence of previous attempts at weight loss perhaps over a period of years or even decades, and this is the outcome we wanted to avoid with the first hypothetical client. For this reason, it would make no sense at all to give them more of the same now. It would make no sense to take an attitude of "we need to lose weight first" via the same restrictive and unproductive approaches.

There are benefits to any amount of activity over being inactive, and benefits to getting out of restrictive dieting and developing more consistent, structured and appropriate eating habits and a healthier relationship with food. When the type of activity resembles some form of what we might describe as "productive training", in a more overweight or obese client we can expect significant decreases in measurements as the body begins to better ultilise energy and resources in support of lean mass at the expense of fat mass, as well as numerous other health benefits.

Here's the curious thing. While seeing significant results in fat loss you'd expect to see confirmation of this when weighing in on the scales, but the reality seems to be that this is not always the case right away. What a pity it would be to fail to value or appreciate the good results in fat loss, strength and performance at training, improved health markers and the rejection of restrictive dieting, just because the scales do not confirm these results with the corresponding loss of body weight.

There's more though. 

To wrap up and reiterate, by developing an interest in productive training and with suitable sports nutrition guidance there will be certain client profiles where weight loss is very likely, certain client profiles where weight loss could be expected but cannot be guaranteed, and let's not forget there will be some for whom weight loss should not be seen as an acceptable outcome at all.

My observation is that when people are focused on and overly concerned with weight loss per se, even when given a good and productive approach to training and the appropriate instruction, the tendency will be to sacrifice the efficacy of the training strategy by falling back into weight loss type behaviours and mindsets as previously described. For example, making changes or additions to the training program "to burn more calories", and to skip meals or otherwise fall short of the prescribed levels of fueling that are required to facilitate any sort of results.

Ironically, it will be the very things that people feel compelled to do because they "are trying to lose weight" which ultimately prevent them from reaping the many benefits of a sensible and productive approach to training.

While there's absolutely nothing wrong with having body composition and condition related goals, we must pursue them with sensible, effective and productive approaches and attitudes, and resist the social conditioning that sees us more inclined towards the extreme, destructive and ultimately futile methods typically associated with trying to lose weight.
