Hi, there. I did a round of medifast back in November/December and I lost twenty pounds. I've kept it off during my hiatus from medifast in January through mid-Februrary. (Unfortunately I had to have surgery and that took me out of the game.) Well, here I am, healthy and ready for round two. I've been back on for six days, with a couple bumps and minor mishaps, but fine-tuning as I go. I am exercising immediately. I am a very active person and the last round I felt like I lost a lot of momentum from withdrawing exercise. So this time I am continuing at my current pace (cycling 3 times a week, and day-hiking at least once a week). Subsequently, my energy needs are higher. I have mostly been eating more protein to make up the deficit. Sometimes I add a little more carbs. I am wondering if any one has heard of cyclic ketogenic methods (AKA carb-cycling) and if this can be applied to the medifast diet. The essential premise is that you replenish your glycogen stores which are depleted from high-intensity exercise, and help promote muscle growth, by eating more carbohydrates. I think traditionally that the "refeeding" or high carb days are a significant increase. However, I was considering doing this on a smaller scale. When I stick perfectly to plan, I usually fall around 85 grams. Maybe my high carb days would be in the 100-110 range? Anyways, I thought I would throw that out there and see if anyone has heard of this or tried it. I like to experiment and find the program that works for my body. Medifast has worked, but so does exercise. And if I can't combine the two successfully, I will give up medifast in favor of exercise and a vegetarian diet.
