This is an utterly naive assessment: To answer the question of "why are people obese" with "not eating enough fruits and vegetables" completely ignores that all the research that demonstrates that it's simply not true. Why do obese people rapidly gain weight after losing it, even with diets that wouldn't cause normal weight people to gain any weight? Why do obese people seem to be simply more hungry than normal weight people. There are myriad questions that your thesis doesn't and can't answer. It would also be trivial to prove this thesis true, yet obesity still tends to confound scientists, especially with childhood obesity, which did not even exist three generations ago.
