If you combine calorie intake with four or five exercise sessions a week, then a 1200 calories-a-day eating plan will help you reach your weight-loss goals. Aim to burn 400 to 800 calories each time (or 600 to 1000 if you weigh over 100kg), and add to that a mega-session on Saturdays that burns 1000 calories or more.
According to the U.S. Department of Health and Human Services 2010 Dietary Guidelines, the typical woman needs about 2,000 calories per day, and the typical man 2,500 calories per day. If you consume three meals per day, your meals should contain 650 to 700 calories for a woman or 800 to 850 calories for a man. Snacking between meals can be a healthy way to stem hunger, as long as you keep your calorie intake to a modest level. If you choose two 200-calorie snacks daily, meals should contain between 450 and 500 calories for women and 600 and 650 calories for men.
