What You Get


Customizable Meals

For online members, vegetarian and vegan meal plans are available. Since the diet is low carb, it could be inherently accommodating to diabetic and dieters with gluten sensitivity. The site also offers some Kosher and Halal recipes.


The theory behind South Beach proposes that excessive amounts of sugar in the blood (caused by high glycemic index foods) lead to a proportionate amount of insulin being released by the liver. As this excessive insulin remains in the blood any sugar that is introduced is quickly metabolized. This causes blood sugar levels to skyrocket and plummet in rapid succession. A person experiencing low blood sugar will feel hungry again before long. If they again choose a food with a high-GI they will repeat the cycle of sugar rush and sugar crash. Naturally, this over-eating can contribute to weight gain.

By taking high-GI foods and most low-GI foods out of your diet in phase one, South Beach attempts to bring your body’s insulin levels back down to a normal range. This phase lasts two weeks, where you should likely lose a good amount of your unwanted weight.

In phase two, you reintroduce nutritious, low-GI foods, which include fruits, whole grains and vegetables. The program projects that you could lose 1-2 lbs. per week during this phase as you reteach your body how to metabolize carbs. This phase continues until you reach your target weight.

There are no restrictions in phase three as the diet assumes you could by then understand what causes over-eating and be able to remember the diet’s core nutritional principals. As long as you stay within the basic guidelines of the program, you should be able to eat anything you want in moderation.

The diet also prohibits trans fats, which are generally viewed as a factor which can contribute to weight gain. Instead, the diet steers you toward unsaturated fats and omega-3 fatty acids, which can be found in abundance in nuts and fish.

Diet Type and Nutritional Balance

The South Beach Diet was developed by clinical cardiologist Dr. Arthur Agatston and puts a signature spin on a classic low-glycemic index diet. Developed for patients with heart health in mind, the diet tries to eliminate spikes in blood sugar levels by removing most carbohydrates from your diet (refined flours, pasta, etc.). Once the body has likely eliminated spikes in blood sugar, complex carbohydrates are slowly reintroduced into your diet, a phase you could hopefully continue with until you reach your ideal weight. By the end of the program, you’re allowed to eat all foods in moderation again—even sweets! Though this third phase of the diet recommends some precautions, they hopefully shouldn’t be very intrusive on your everyday life.

Hunger Factor

South Beach is also unique in that there are few restrictions on portion sizes so long as you stay away from the banned foods list for each phase of the diet.

Indulgence Allowances

For the first two weeks, the diet strongly suggests that you not eat any of the prohibited foods as they could disrupt the corrective measures the diet is trying to implement. Phase two should allow for some sweet treats like fruit popsicles. In phase three, you could go back to enjoying all foods in reasonable portions.
