This is actually a highly valid point.

If the answer is "yes" so what? If overweight individuals could be less overweight then don't you think they would be already?

Kind of like asking a heroin addict "will using heroin hurt your career?" Yes? Oh well let me quit right this second then...

Ditto smokers, alcoholics, other eating disorders, depression, mental illness, drug users, sex-addicts, internet-addicts, et al.

I'm no expert on curing this stuff but I do know that shaming them or putting tons of pressure on them (quit or X Y Z will happen) is the opposite of progress.

I don't know - sometimes external motivation can help. i.e I lost two stone (28lbs) because a) I was approaching my 40th birthday, and didn't want to be fat and 40, and b) I wanted to stay healthy for little girl.

Priorities and time. The OP might be quite comfortable and happy with his current physicality, so he's not interested in investing the time getting thinner "just because". However, he might be highly dedicated towards creating a profitable business. And if being thinner is something that might provide an advantage to that end, then it's worth prioritizing and making the time to do so.

Doesn't every other person say doing a startup is a 24/7 commitment? It's hard to quit the refined-carbohydrate yo-yo in the middle of that.

Maybe it's as simple as that particular co-founder won't come to the meeting for raising capital?
