Being unable to stay away from certain foods, especially sugar, has nothing to do with willpower. Rather, it's the result of an addiction caused by a complex interplay of chemicals in your body. So don’t beat yourself up about it. Recognize the addiction and find healthy substitutes for the foods you can’t seem to live without.  As far as sugar and sweets are concerned, consider natural, non-caloric sweeteners for a while (such as monk fruit extract and stevia).  Check out the recipe section on this blog for some treats that we enjoy frequently.
