Kick your sugar cravings to the kerb with these 10 ways to tame your sweet tooth. Sugar cravings are often a sign that your blood sugar levels are unbalanced. To help maintain normal blood sugar levels, try to eat little and often ­ having smaller snacks throughout the day ­ and opt for low-GI (glycemic index) foods which will release energy slowly throughout the day and not result in energy peaks and crashes. Good low-GI foods include non-starchy vegetables, nuts, legumes and complex carbs such as oats and brown rice.
