Lasting weight loss comes from the inside, not the outside

It’s quite remarkable just how much we continue to search for well-being and happiness from outside sources, such as a new job, new relationship, new car, hairstyle, watch, suit, dress, shoes, and the list goes on. If you take a step back and look at our general way of life, it kind of feels like we are conditioned to run around the treadmill of life constantly in need of outside things and gadgets to make us happy. Of course, we rarely get any lasting fulfillment in getting those new shoes, or whatever we long for, yet we keep doing it over and over again.

The same can definitely be said of dieting. The pattern of weight loss and regain will be very familiar to all those who struggle with weight problems. A very large part of why dieting fails is that we don’t get to the bottom of why the weight gain occurred to begin with, and, even though there are different ways of looking at this, my view is that the vast majority of weight gain comes from the inside in the form of negative thoughts and emotions. The origins of those negative thoughts and emotions can be very complex but there is no doubt that they usually make their debut during childhood and stay with us as adults, consciously or not.

Negative thoughts and emotions have a huge influence on our health and well-being, and obviously our weight, both in terms of regulating stress, metabolism and inflammation, but also lifestyle choices and habits. This is why I am convinced that any lasting weight loss is very unlikely to come from outside sources, it needs to come from within. Once you start to understand more about your thoughts and emotions, you can shed the weight in a very natural way, because, in a sense, your body will no longer have its fat storage programs activated (set-point theory) as a result of psychological and emotional distress.

Obviously it could take a while to go through such an internal cleaning process, but I also believe that it does not have to take years or decades, it’s really up to you how hard you work at it. And you should certainly get qualified support if you need it.

But if you skip working on your internal issues and instead go for what you perceive to be the easy way out, i.e. trying a solution from outside sources such as a diet, you are not likely to be successful long-term since those fat storage programs will still be activated, and the weight will likely come back on. Or you will need to be super disciplined in terms of what you eat and how much you exercise for the rest of your life. Some people manage this, but not very many (I know I wouldn’t).

In terms of losing weight long-term, I believe it’s about time we stopped fighting against our bodies and instead realized that we need to work with our bodies instead. If you are carrying excess weight, it probably means that your body has activated fat storage programs as a result of your internal distress (fat is basically a survival mechanism, and your body is reacting quite naturally to stress). Your best bet in deactivating those programs will be to find out why they are activated to begin with, and then gradually turn them off by releasing those internal distress factors.

Why is long-lasting weight loss so hard?

Losing weight is not easy. Not at all. But keeping it off is even harder. This is not new knowledge, but it is only recently that we have started to find out why it’s so hard to keep it off. Last year, I was working with some colleagues on a meta-analysis that evaluated different strategies for keeping weight off after a period of rapid weight loss using a very low calorie diet (<1000 kcal/d). We evaluated different types of diets (low GI, high protein, and so on) and supplements, exercise and finally anti-obesity drugs.

What we found was pretty depressing: none of the strategies were very effective at helping people keep the weight off. This much we were able to conclusively prove.

This got me thinking about how the body defends against weight loss. I concluded that there are at least three types of primary defenses against weight loss, all of them powerful and hard to dodge for anyone wanting to lose weight long-term. Moreover, the defenses operate according to the rubber band principle: the more weight you lose, the more defense activation, and hence weight regain, you are likely to experience.

First, once weight loss occurs the body will increase circulation of appetite increasing hormones and peptides, such as ghrelin (increases hunger) and leptin (increases satiety). Sure, you can override this cognitively, at least for a while, but you are basically swimming upstream from now on. It’s doable, just not very easy.

The second line of defense is called adaptive thermogenesis. This means that your body goes into calorie saving mode once you have shed some weight, and you will now burn a lot fewer calories during both rest and exercise. This reduction in metabolism is a lot lower that what we would normally expect as a result of having a lighter body.

The third line of defense is behavioral relapse into old habits. Some habits are formed early in life and are manifested in the brain. By losing weight you needed to change your old eating and exercise habits and form new ones. But those “highways” in the brain didn’t just go away, they are still there. And we are indeed creatures of habit, and after a period of fighting those first two defenses, those old habits can easily make a comeback when you feel tired and stressed.

And there also appear to be more defenses, not least psychological and emotional ones. One such example is that many overweight individuals identify with having extra pounds, usually established already in childhood. This means that they are used to a looking heavier than others. Once they lose weight, some individuals will struggle to identify with their new appearance, and consciously or not, they can can feel uncomfortable and regain for that reason, no matter how much they want to appear thinner.

My suspicion is that children who grow up overweight will have a harder time losing weight that adult-onset weight gainers for this very reason, since adult-gainers do not identify with being overweight to nearly the same extent.

The highly visual nature of obesity could in fact be one of the reasons it is so hard to treat long-term, at least with current reactive methods, such as drugs, diets and exericse.

I can understand if you feel a bit depressed reading this but in order to make real progress we have to understand why we have been failing for so long. Now we at least know a bit more about what does not work and why. I say that is at least partial progress. Real tangible progress will happen when we find methods that do not trigger these defenses in the same way or perhaps even avoid them altogether.
