May I pop in here? I have done Adkins and M&E, both had good results but I felt sluggish and I found it hard to stick with. One week ago, I started what I call semi-low carb and I feel great. I have energy to excercise and I don't have the cravings. I eat anywhere from 30 - 50 carbs a day and I am going to start carb rotating 2x a week. I do believe there are benifits if eating nutrient dense carbs.
I do cut back on the fat intake, but on an average day, I eat around 45% fat. I don't cat that low fat, I call that moderate fat. In my opinion, just the way it should be. I also count calories, I tend to rotate between 1,100 and 1,500 calories, it all depends on the day.
I think most diets have merit, but, moderation is the key. Moderation to me is different to others. Moderation with a piece of cake is one every few weeks, to my sister, moderation is one a day. I can't do sis's "moderation", I would be eating the whole cake within hours
Anyway, off the point, I like semi-low carb, the only problem that I saw with South Beach is that they limit fat. If I can't eat a chicken leg or steak I may go nuts! But, the diet does have very good merit as others do too.
Semi-lowcarb obviousely has many different numbers. 125 a day scares the heck out of me
