The South Beach Diet has been popular for many years. Developed by Dr. Arthur Agatston to help his patients with heart disease, it was observed that the diet led to weight loss.
Simply put, the South Beach Diet is a low-carb diet that has been associated with rapid weight loss without cravings, all while improving heart health.
Here is everything you need to know about the South Beach Diet, including potential benefits and drawbacks.
What is the South Beach Diet?
The South Beach Diet plan focuses on foods that are rich in nutrients, high in fiber, and low in carbs. Allowed foods include lean protein, healthy unsaturated fats, and low-fat dairy.
There is a difference between good and bad fats, as well as healthy and unhealthy carbs. Bad fats and carbs are high in calories that cause you to gain weight around your midsection, and they also cause blood sugar spikes that can make you feel tired, irritable, and bloated.
The South Beach Diet emphasizes low-fat, low-refined-carb, and high-fiber foods that provide you with a steady and consistent release of energy.
What are the different phases of the South Beach Diet?
The South Beach Diet is to be followed in three stages, similar to the Atkins diet.
Phase I
The first phase of the South Beach Diet kick-starts the weight loss process and is the strictest phase. It lasts for 2 weeks, resulting in an average weight loss of 8-13 lbs.
During this stage, you should avoid foods that are high in refined carbs such as white bread and pasta. You are allowed to consume only lean meat, fish, vegetables, and small amounts of low-fat cheese. You can also consume a maximum of 250 mL of skimmed milk every day. Oil should be used only for baking and roasting.
Foods allowed during phase I of the South Beach Diet include:
- All vegetables except white potatoes, carrots, beets, corn, yams, turnips, peas, and winter squash
- Lean proteins such as lean chicken and turkey
- Nuts such as almonds, walnuts, cashews, macadamia nuts, pecans, and pistachios
- Seeds such as pumpkin seeds, chia seeds, flaxseeds, and sesame seeds
- Oils such as olive, avocado, macadamia, canola, corn, safflower, grapeseed, peanut, sesame, and flaxseed
Phase II
The second phase lasts until you reach your desired weight, with the rate of weight loss ranging between 1-2 pounds a week. The diet mostly consists of the same foods in phase I, along with good carbs such as fruits and whole grains, which should be added gradually.
Foods allowed during phase II of the South Beach Diet include:
- All foods from phase I
- Fruits
- Starchy vegetables
- Whole grains
Phase III
The last phase involves weight maintenance. During this phase, there are no restrictions, although it is recommended to eat three filling meals a day without snacking. Meals should include:
- Lean protein
- Vegetables
- Fruits
- Whole grains
Once you reach this stage, you may slowly go back to phase I and continue the diet process periodically to maintain your ideal weight.

Can you really lose weight with the South Beach Diet?
According to some claims, the South Beach Diet can help you lose up to 8-13 lbs during phase I, then lose 1-2 pounds each week during phase II.
Studies have reported that both men and women who followed the South Beach Diet experienced reduced body weight, fat percentage, waist circumference, and body mass index. It is believed that weight loss is due to the following factors:
- With carb restriction, your body goes into ketosis while decreasing glycogen levels and promoting water loss.
- The emphasis on whole foods and low fat may result in a calorie deficit, which aids in weight reduction.
- Fiber and protein keep you satiated for longer and prevent you from overeating.
Much of the weight loss seen in phase I is water weight, which is bound to come back. However, the weight loss in phase II is sustainable and can potentially lead to long-term fat loss.
