I have that issue. The solution is... you don't go back to eating a high carb junk food diet that you know is bad for you. It's a lifelong change to eating patterns. Nuts not candy. Sugar free soda. Salads and greens with dinner, not potatoes. Low sugar fruit, not cake. Plus points, All the high fat diary products you can handle and a fry up for breakfast every day. Never feeling really hungry, way more energy.
