Somatypes are an ancient pseudoscience, while caloric intake relative to TDEE doesn't lie.

If obesity were taxed, there would be pressure to put loopholes in those taxes. Somatypes and "thrifty genome" and so on would be perfect hooks to hang those loopholes on. Result? Questioning that science becomes politically untenable, at least in some universities and research labs. After all, "the grants just follow the illiction returns", as the poet once said:

I lost 25 kg. In 6 months, with counting calories and all. But the amount of effort I had to deliver for a normal weight is almost exponentially more

1 hour strength training per day

1 hour cardio in the morning

No alcohol

6 * eating small portions

8 hours of sleep

1 cheat meal per week

Every day, no exceptions.

Regardless of any minor variability in metabolism, you literally cannot get fat from things you don’t put in. This is like high school or middle school physics. This is by far the biggest factor in obesity (consumption).. such that everything else is essentially irrelevant. People with actual metabolism disorders either die or require replacement of enzymes, whether that’s type 1 diabetes or the rarer metabolism disorders.

If you eat high volume foods with calories at or below what you’re expending, you will not get fat, full stop. Starving people aren’t fat.

There are of course behavioral differences that dictate consumption, some of which are genetically influenced, but metabolism has not much to do with it.
