I'm having trouble understanding what you mean by noting this - would you mind clarifying?

If he's overweight, it suggests that his self-help advice is ineffective. Of course there are a few alternate explanations: That his advice is effective, but not sufficiently effective to diet successfully. Or that he doesn't care about being fat. And probably others too.

Still, successful weight loss is one of the closest things to guaranteed success if you are able to get your s* together. As opposed to other goals like getting rich or finding and marrying the love of your life. And there are so many advantages to being thin that pretty much every fat person has tried to lose weight. Some of them, many many times. So I wouldn't trust a fat self-help guru.

Hope that clarifies things.
