Weight is always tough to keep off especially around the holiday season. I am not sure what CLA is but if I were you I were stay away from non-natural stuff as well as many fat burners because they are basically nothing more than a lot of caffeine and things that block appetite which in the long run don't do a whole lot of good. If you can just use healthy meals to get your metabolism up and workouts to get some extra calories burnt than you will be good and it will save you a lot of money you could waste. I agree with whoever said it above, a protein shake for breakfast will keep you full well into the afternoon.
