I've have tried to preach the multiple meals & eating properly to my partner for years. From what I've seen with him...Slimfast/Atkins & the 6 week body makeover only work while you are motivated.
Being that I'm 6'9, my problem has been gaining & maintaining weight, which has lead me down alot of misguided paths.
However, I was finally able to hook up with a trainer who was/is a "natural" body builder and he has told me several things about managing ones weight.
1. To loose weight, one needs to boost their matabolism.
This is most commonly done via exercise. But not everyone has time to work out. So, he also suggested to increase the number of meals through the day (5-6 small meals). Breakfast was/is the most important of these meals.
2. When exercising, you need to get your heart rate to the "fat burning" zone for at least 20 minutes. The fat burning zone differs for everyone, depending on age & fitness level.
Sex can get you to the fat burning zone, if you're doing it right
3. Your body needs REST. You must sleep at least 6-8 hours a day (depending on your bodies recharge time. Mine is 7 hours minimum)
4. You must stay hydrated. We all know water makes up ove half of our bodies, but how many of us drink a can of pop, over a glass of water? He also says to STAY AWAY from caffinee as much as possible.
I'll stop now, but hope this helps?
