After many people mentioning the book ‘Why We Eat’ by Dr Andrew Jenkinson I finally got round to reading it. The premise of the book is that it explains why we all have a tendency to overeat and gain weight. While it had some good points the book is just another rehash of set point theory which I have yet to be convinced by. I feel set point theory, especially in its purest form like in this book is not just wrong but causes most people to quit before they ever really get started. 

If you are not aware of set point theory, it suggests that the body, through the use of certain biological processes has a weight that it is most comfortable at and if you go below this then your biochemical defense systems kicks in to bring you back to your previous weight range. In this book he links the set point to processed food, carbs, insulin, Omega-3, stress and cortisol levels among other things. His solution is essentially based around a low carb diet approach of home cooked foods. 

The book made almost zero reference to anything to do with psychology around food, exercise or changing your body. This became almost laughable towards the end of the book where he tried to explain the weight gained by people going to university as some evolutionary change of moving out of the family nest and nothing to do with students getting up late, drinking a lot and having no parents around to tell them to stop some of those bad behaviours.

I always wonder why proponents of a theory are so closed minded that they have to explain everything under their one approach. For example, the low carb or keto proponents just cannot accept that some people do well on higher carbs. I wrote the Grand Unified Theory of Weight Loss to account for all possible elements that are actually seen in the real world and not conveniently pretend that millions of people are not getting results doing the exact opposite of ones own approach. 

How Does This Apply To You

I feel the vast majority of set point theory’s claims can be explained by psychology and the mind set of the individual rather than biochemistry. There is definitely not this magical, mysterious barrier that is stopping you dropping a few kg to achieve your goal. The problem with set point theory is it causes people to adopt a learned helplessness ethos around body transformations which creates a self-fulfilling prophecy around not getting results.

There are huge holes in set point theory, millions of people lose weight and keep the weight off for life. Many millions more lose weight and keep it off for many years. What happened to the set point during these years of easy maintenance? It does not explain why some people can lose massive amounts of weight and keep it off. While it may be that they changed their set point during the process I believe that the mind changes first and the biochemistry follows afterwards if at all.

You can change your body and you can achieve your goals. It may take a while to get there, you almost certainly will have to take a different approach to that which you have been doing and you will need to learn how to transition from period of making progress to breaking even to allow the mind & body to recharge. If you put these things together you will achieve the impossible. DO NOT get caught up in the defeatest attitude of set point theory activists.
