I've been on flex since new year's and I've gained 5 lbs. Since I paid for 10 weeks I'm going to do core. I've done well on low(er) carb plans before, but found I couldn't enjoy the limitations and I need variety. I'm sure that calorie count alone doesn't work for me, it does matter what I eat. And I know the lower fat, higher carb food has the lowest points values, and to eat enough to stay satisfied and within the points range I had to eat bread, etc. So, off with the bread, pasta, cereals. I know they make me gain weight, I just always fall for what's popular in the dieting world. I've gained more on flex that I did eating whatever I wanted over the holidays!
