How bodies related to food varies _wildly_. For example, my body has difficulty processing certain foods, so I lost a ton of weight switching from "healthy" fruits and veggies and plant-based protein to mostly pre-processed carbs and fatty meat. (Low FODMAP, for folks who are curious: be ready to learn chemistry to figure out what is safe to eat.)

That diet isn't going to have the same effect for most people, but in my case it significantly lowered my inflammation and general discomfort, which led me to lose 90lbs with no actual effort on my part.

I knew one dude who was always hungry and it turned out he just desperately needed B12. Now he snacks on B12 gummies and feels much better. Debugging our bodies is more complicated than debugging a software program, but no programmer would say "Just run the program less!" if someone complained a program was eating up all the CPU.

The one thing that is always good for humans, whether we lose weight or not, is some physical activity. Whatever we can enjoy enough to do regularly, without injury, is a great choice.

I wish the medical profession would stop focusing on diet, when it doesn't understand it and calorie restrictive diets are one of two lifestyle components we know actually do contribute to obesity.
