I am overweight but not obese. But this is not an anecdotal issue, the literature is crystal clear on this.

I know personally not one but some obese people that became fit only with diet (mainly long fasting) and exercises. I myself had an obese BMI (32) and now it is normal (24).

You can choose a better literature. It is all over the internet.
