Being overweight is not a recipe for health. I agree completely that it is a very hard problem for many to address. I used to be chronically overweight though not obese and it was a complex problem for me to address – checking for behavioural reasons for eating too much, trying to understand how the wrong diet can cause hunger rather than satiation, understanding how upbringing (you will not get pudding unless you clean your plate) and may other factors fed (oops, pun) into that.

Accepting that it is a problem but not a moral criticism is the starting point.

Once you get past that, you can start creative problem-solving.

Fad diets are absolutely the worst thing because they lay on the moral criticism: you do something that is supposed to work but it doesn’t. It is not your fault. A fad diet is a bad idea to start with. Everyone is different: what works for one person may not work for someone else. I saw the same issue with miracle cures for tobacco addiction. There is no such thing: it is a really hard problem to solve and you need to find your own way out of it – with help if need be, but you need to own the solution.

Know your own mind and body, how they react to stimulus, and start developing a positive self-image about your ability to problem-solve. That will take you to a much better place not only for your health but for your general ability to cope with life.
