Pay attention,
I have a degree in Nutrition and Biochem...
yes, you can’t gain weight from nothing, but you can have a metabolism so slow and disease states so profound that weight loss is extremely difficult in ‘fast and easy’ terms.
Plus you have genetics, fat storing/famine hormones, aging, activity etc. It’s not ‘gee, just eat a little less dear and you’ll be a size 2 next week!’
You may have to accept that the smallest she can be and be healthy is a size 12, and it may take her a year or two to get there.
That’s the reality.
And the other reality is that if she’s married to an uncaring selfish lout, she’d be better off leaving him and THEN losing weight.
Sigh..... I never said that it was psychologically easy to eat less... just that the actual function of losing weight is an easy solution... eat less. And yes, it takes time... never said otherwise.
And the medical situations you are describing really only fit a small subset of the population that is obese (men and women).
I've had plenty of chuckles listening to very fat people complain about their "metabolism" after stuffing their faces with 3 times the food I just ate. I pass on desert, don't drink soda and eat reasonable portions because I actually care enough to make that sacrifice. Selfish people don't care enough to limit themselves.
And you assume that all men who think their wives should care enough to lose weight are "selfish louts". LOL Your bias is showing.
I consider a woman who lets her self go to be a selfish lout myself, and the man would be better off leaving that type of person as well. Let the next guy deal with a woman who cares so little about her husband that she refuses to be fit for him. So I guess it works out!!
