premise: If you had said that dieting alone doesn't always work, <hypo>, but what you're saying is "hey everyone! Stay fat! Eat cake and cookies and pizza and fries and burgers because no matter what you cut from your diet you won't lose weight because you can't do it and you're just gonna out the weight back on!" No, that's not always the case.
hypothesis: <hypo> should be "I might've agreed"
