You hit the nail on the head. The fact that naturally thin people will rarely admit is they are that way naturally and didn't do anything to get that way. They are lucky because they got dealt a killer metabolism hand through genetics. Do some people drop weight with diet and exercise? Sure, but it's exceedingly rare despite massive effort to keep the weight off! I've been overweight my whole life and believe me, I didn't want to be a fat girl. I've been on every diet on the planet and have Hashimotos. My husband has battled his weight his whole life, too, and is blessedly taking a compounded form of GLP-1 so the constant voices tell him to overeat will stop!
