How long wil it take to see a difference after I start dieting in?

It depends. The best thing to do is start a no-sugar eating plan along with regular exercise. If you can download a free weight loss app, you can follow your progress---calories in, calories expended (with exercise), and daily weight. That way you'll be able to see your progress and not become discouraged. Congratulations on eating in a healthier way! look up "healthy eating" on health tap.
