Do you mean 4-hr Body/Slow Carb? I have done it once before, and lost about 40 lbs 2 years ago.. It works really well, I just quit doing it..
My favorites are the cheat day, because I can be very finiky careful about what I eat for 6 days, as long as I can cheat on the 7th.... I had done body-For-life also in the past, which also has a cheat day...
So, at least I hope to learn from my diet quitting mistakes- I personally need a cheat day, lots of protein, lots of vegetables, and lots of exercise..I'll eat beans, since they are part of the plan and I know they work..I can eat until I am pleasantly full, and not have to portion count, or carb count, and still lose weight..
Depends on what you need in a diet..
for ex.. I tried being vegetarian at various times, but found it too difficult for me to get enough protein, while not taking too much carbohydrates, but I know several people who make splendid vegetarians...
I think this is now officially my 11th day doing this..
I've lost about 12lb,but that is often water weight if you cut carbs.. I like that I can also not be distracted by carb cravings after a few days, even though I eat carbs on my cheat day..
I do like having people to talk to and be accountable to.
