Have you tried doing some sports instead? Cycling, swimming or even a long walk in the park are decreasing at least my depression and anxiety and while doing sports at moderate levels, with good hydration, I don't feel the need for sugars anymore. I'm also fat, in love with chocolate products, cakes and sweets don't survive the day uneaten in my home, no diabetes so far. I don't recommend running because of it puts to much strain on the knees.
