This British study found that over 20 years, low self-esteem leads to obesity and not the other way around.
I believe low self-esteem leads to poor eating habits, especially the need to stuff yourself with sweets, which makes us feel the need to eat ever more carbohydrates to feel full.
It’s called stuffing your feelings instead of letting them out and dealing with them, and it can turn into a never-ending vicious cycle. We stuff our feeling and try unsuccessfully to hide them. Pretty soon they are showing all over our body!
