Maybe, but most of us do it.
And if you are selling a health or weight loss product, watch out!
Those eyeballs check you out. The brains instantly go, "Why should I buy any weight loss product from you? You're overweight (or not healthy looking) yourself. Obviously your product doesn't work."
And that's that. No sale. Of course they won't tell you why not.
Here's what you can do.
1. Lose weight and get healthy yourself. Fast. So you look the part. OrIf you're using weight loss products and they're not working fast enough, there's a reason. And it is NOT necessarily that the products or shakes don't really work that well.
2. Market a different product altogether where your appearance does not get in the way. Or
3. Find people to sell your weight loss products to who don't notice (or care) that you are overweight yourself.
