Dr. Atkins' New Diet Revolution
The concept: Robert Atkins, M.D. claims that restricting carbohydrates will make the body burn fat and ultimately shed weight.

The foods: Meats, poultry, seafood, eggs, cheese, butter, cream, some (non-starchy) vegetables and artificial sweeteners.

Conclusion: Bacon is OK, but fruit is not? Not necessarily. This diet is high in saturated fats and can raise the risk of heart disease, something that can be especially dangerous for people living with diabetes. Carbohydrates are the body’s main source of fuel. Omitting carbs completely can lead to fatigue and reduced energy levels.



The South Beach Diet
The concept: Arthur Agatston believes that a diet filled with “good” carbs curbs cravings and causes weight loss.

The foods: Like Atkins, the South Beach diet limits carb intake during its first phase, but includes heart-healthy foods like lean protein, healthy fats and most vegetables. In the second phase the list grows to include whole grains, most fruit and low-fat dairy.

Conclusion: This diet is a better version of the Atkins diet with heart-healthy foods that are important for people living with diabetes. However, only 1,200 calories are allowed each day, which can be low if exercise is part of the weight loss program.

The Zone
The concept: Barry Sears’ plan relies on maintaining the correct ratio of carbs to protein to fat (40:30:30). Weight loss is promoted by keeping insulin in “The Zone.”

The foods: This diet is less about specific foods and more about portions.

Conclusion: Being mindful of portions is vital in keeping a healthy weight. However, counting in a 40:30:30 system can be complicated.

Volumetrics
The concept: Barbara Rolls and Robert A. Barnett encourage cutting calorie density for weight loss.

The foods: Fruits (no juice), vegetables, pasta, oatmeal, soups, salads, low-fat poultry, seafood, meats and dairy. Limits fatty foods and dry foods such as crackers, popcorn and pretzels.

Conclusion: Focusing on heart healthy, low-calorie foods that are high in nutrients is a good plan.
