In a Nutshell
- The South Beach Diet was developed by a cardiologist
- Founded on eating “good” carbs and avoiding “bad” carbs

- Gradually add in limited amounts of whole grains, some fruit, and more vegetables.
- Remain in this phase until you reach your goal weight.
- Weight loss is estimated at 1-2 pounds per week.
- Considered the maintenance phase.
- All foods are allowed in moderation.

Cutting out all carbohydrates in Phase 1 could cause fatigue and intestinal upset.
Phase restrictions and heavy reliance on artificial sweeteners may make this diet difficult for some to follow.
Scientific & Expert Support
The South Beach Diet, despite being developed by a physician, is not based on any scientific research. The list of foods to avoid includes some foods that are known to be nutritious.
Experts are concerned about some of the diet’s claims and comparisons, such as a banana and a brownie being essentially the same because they are both high in carbs and can cause blood sugar spikes. It is well known, however, that bananas are a nutrient-rich food containing essential vitamins and minerals whereas brownies have little to no nutritional value whatsoever.
Following an eating plan rich in healthy, whole foods carbohydrates and dietary fats may contribute to weight loss as well as lower cholesterol levels.
While this diet is relatively balanced and generally safe if followed as outlined in the official books and websites, consulting your physician, and ideally a registered dietician (RD) or nutritionist, before changing your diet or eating habits is recommended. Especially if you are pregnant, breastfeeding, are taking prescription medications, or have existing health conditions.
Severe carbohydrate restrictions may cause brief side effects brought on by ketosis, which can include nausea, headache, difficulty concentrating, dehydration, dizziness, intestinal issues, and bad breath.
STRENGTH OF EVIDENCE: C
There is plenty of quality research supporting the benefit of low-carb diets for rapid weight loss, at least in the short-term, but there is no evidence directly supporting the health effects of the South Beach diet.
Like most low-carb diets, chances are you will see rapid weight loss on any low-carb diet. The South Beach diet is now different. The initial weight loss is mostly water weight. However, low-carb does not necessarily mean healthy. If you do choose South Beach diet opt for eating whole foods while avoiding low car processed junk food.
