I am 7 months in and I have lost 53 pounds. I hit the 50 pound mark at 6 1/2 months. I did not have the goal of 50 pounds in 6 months, though. Now, I am 7 pounds away from my original goal of losing 60 pounds. I have not done anything crazy, but instead eat less and exercise more. I am in better shape than I have been in about 15 years. So, I do believe 50 pounds in 6 months is very doable, if you really have 50+ pounds to lose (I did). My only thought about food is that I no longer eat anything ( about 99.9% true) unless it is fuel for my body. No junk food, candy, cake, pop of any kind. Research shows one of the highest predictors of successful weight loss is tracking your food intake accurately every day, so I use the Lose It app on my iPad. So, good luck. One suggestion, though, is to set a goal weight that is reasonable and go for it without a time constraint. I believe taking a little longer is healthier and more likely to work over the long run.
