Well, if you want him to lose weight in 2 weeks eating that many carbs... he won't lose much. I tried Atkins and it's the only diet that has worked for me. Some people do better on low cal/low fat, I do better on low carb. Carbs have always been my weak point. He will lose weight, but not more than low cal IMO. Not eating that many carbs. If he really wants to lose weight he should excercise at least an hour each day and stay 10g or under. That causes the body to go into kietosis (I think) and start burning body fat for energy. The adjustment period is two weeks. Then the real weight loss starts. He won't lose much in 2 weeks as it is, and even less on that many carbs. It takes the system a while to realize stuff. At least, that is what happened to me. I have gone on Atkins numerous times, and it all works best when I drink lots of water or crystal light or iced tea with Splenda and stay under 5 grams of carbs and exercise. Good luck
