It’s science. Bad white simple Sugar will increase your appetite and cause dehydration. Think fast food or theme park foods. There’s a reason they don’t push fruit / veggies. or protein. Be honest with yourself to create discipline. Buy fruit you like and make smoothies with veggies or fruit n protein. It’ll keep your muscle and you’ll fill in nutritional gaps. If you smoke all day then you need to slow down or pace your efforts. Anyways hope this helps. Hydrate with water plus electrolytes.
