| Basically the South Beach diet is the Atkins program with some modifications. Sadly Agatston does not give Atkins credit. In fact on page 10 he states, "the Atkins Diet, for instance which bans virtually all carbohydrates and leaves the dieters to exist mostly on protein." Anyone who is familiar with Atkins knows that though Atkins plan does ban carbs for the first two weeks in the induction phase it later allows carbs back into the diet and the individual works up to a carb allowance where he/she will not gain back weight. And yes with Atkins whole grains, pasta and potatos are allowed according to the individuals metabolism of carbs. So this quote indicated that the author was either unfamiliar with Atkins or just twisting things so his own diet was more appealing. Agatston also claims his diet is not low carb. But in the first two weeks you eat very limited carbs and after that you add carbs back to your diet according to what you can handle (without gaining weight) so if you consider Atkins low carb, which does the same thing you will consider The South Beach Diet low carb. You begin the diet with a two week period where you do not eat rice, pasta, bread, fruit, potatoes, etc. After the 2 week period you will according to Agatston lose between 8 and 13 pounds. When your 2 weeks are up, you go to Phase 2. In Phase 2 you add back carbs that are good carbs like whole grains, fruits etc.
You continue to lose and then when you have reached your goal you switch to Phase 3. This is where you eat your foods in normal portions, but live by simple rules. There are two main differences between Atkins and Agatston. Agatston does not suggest you go into ketosis as Atkins does. And Agatston suggest you limit saturated fats unlike Atkins. Other than that, the diet is essentially the same. Agatston suggests eating fresh fruits, veggies, whole grains, unproceessed foods and fat etc. just like Atkins. Agatston's book is not well written either. He skips around in the book and doesn't clearly spell out the plan. The reader is left to infer what the diet is as he reads the book. A much better book choice would be to get "Atkins for Life" where everything is spelled out and eat less saturated fat. Agatston also states you don't have to worry about counting calories. Sadly no matter what diet you are on, as I found out the hard way, calories count. The reason low carb diets don't require you to count calories or watch portions is because protein is very satiating and naturally suppresses the appetite. So most folks will not overeat. But there are some who will. And if you cheat just with some carbohydrates and are eating the fats and proteins that low carbing allows you may very well gain weight.
Bottom line calories count. Agatston gives menu plans in the back of his book. These are cut and dried with no substitutions listed. And when you add up the calories, menu plans are approx. 1200 or so. No wonder you will lose weight! One good point Agatston does make is if you add fiber right before you eat a meal in the form of say a spoonful of Metamucil you will slow down the processing of your food and feel fuller. If you want to lose weight, eat protein to help you feel full. Eat healthy fats. Eat unprocessed carbs (fruits and veggies) and eat few starchy carbs (rice, potatos).
And eat moderate portions. Agatston tells you this but its already been said before. |
