I have been taking it for about 2 weeks and have been rather pleased with the results. I have only been working at losing weight for about 3 weeks. Started @ 272lbs. weighed in a 255lbs this morning. I truly feel my results are accelerated with the help of muscle milk. I work out usually late morning, and then have the M.M. as my post workout/lunch replacement. It is very filling, this is coming from a guy that could eat 4-5 slices of pizza for lunch, now I have my shake and I don't even think about food until 6-7:00 pm...Honestly it tastes pretty good as well. (banana creme) I would also recommend mixing with water and crushed ice. With milk it seems to be too rich. I think after another week of progress I will be getting more serious with lifting and will be taking a shake about an hour before bedtime as well. I will keep you guys posted if this creates any changes..
