Discover the Science Behind the Magic of the South Beach Diet

A no fads, no gimmicks approach to weight loss developed by world-renowned cardiologist Dr. Arthur Agatston.

One thing was clear to Dr. Agatston. His patients were frustrated. They were confused by the conflicting information swirling around about quick fix diets that left them tired and hungry.

The South Beach Diet was his solution. Understand: The South Beach Diet incorporates good carbs, healthy fats and plenty of lean protein. Nutrient-dense foods that can turn off the switch for sugar and refined carb cravings.

This healthy way of eating has been around for years, but it's Dr. Agatston and his famous 3-phase approach which has allowed over 11 million people to choose South Beach Diet to meet their goals.

Now it's your turn!

Burn Fat Without Hunger

In Phase 1 of the South Beach Diet, you'll stay away from sugar and refined carbohydrates–foods that digest quickly, cause you to be dependent on carbs, and keep you trapped in a constant cycle of cravings and overeating.

During these two weeks, you'll reboot your body, eating foods high in lean protein, plenty of vegetables and healthy fats. Now your body will attack your fat, burning it for fuel since your carb intake is being kept at a low consumption rate. You'll lose weight fast without being hungry.

As your body converts fat to energy, shifting your internal chemistry, your cravings for junk food and sugar recedes, replaced with a growing need for healthy, nutritious foods.

Your body is now reset and you're ready to move on to the next phase of your diet.

Advance to Steady Weight Loss

As you transition into Phase 2 carb-heavy foods are no longer your must-have source of fuel. You've trained your body to burn fat for fuel—weight loss will continue at a steady pace. You're ready to reintroduce fruit, whole grains and some starchy vegetables, enjoying them in moderation. Having successfully reset your body, you'll find that your body wants different foods than it did before—foods that fuel! This balanced approach to eating will drive you toward your goal weight.
