But like, the kinds of modern diets that produces obesity are traditionally missing vitamins so, it could easily just be that eating a family-size bag of Cheetos for a meal will leave you fat with malnutrition.

This. This chronic malnutrition overlays with environmental pressures such as sickness and toxins, which like I've literally explained thoroughly, the liver and vitamin stores then get even more depleted as they use these vitamins in your immune system to deal with this. People then crave high fat foods and gain weight chasing the small amounts of vitamins in their food. The vitamin deficiency causes the cravings. If you give them vitamins, esp vitamin k and vitamin e, they will not seek out high fat foods as much.

I have celiac disease, a fat malabsorption diease. I used to crave sticks of butter, like eating it like a chocolate bar. This (eating sticks of butter) is actually so common in people with celiac that it's one of the first things I ask about when I meet someone else with it. Now that I have proper vitamin levels, I crave yogurt, fruit, and lettuce, and biting butter makes me wanna yarf. A sign I need to supplement or eat fat soluble vitamins is if I start really craving fats.

Good luck
