Ok, I started the Curves Weight Management thing on Monday. Their program is very metabolism focussed. You do a week at 1200-1400 calories, ~6 weeks at 1400-1600 calories, and when you stop loosing weight or need a break, they have a 2000-2500 calorie program. The whole idea is to keep from switching your body into starvation mode where you stop loosing weight. And you have a choice of high protein (60/40 protein/carbs) or high carb (40/60 protein/carbs).
I'm doing 1400 cal on the high carb plan, and I haven't killed anybody yet.
Actually, I'm doing ok. Monday was REALLY hard. Hungry all day, thinking, I can't do this. Tuesday was better, and it's been better every day since. In fact, I just realized I didn't eat the 60 calories of fruit allowed with lunch (that's like a cup of raspberries, so pretty filling!). But I'll eat it with my snack, or maybe dinner. Mostly this diet is portion control, and balancing protein and carbs. I'm not sure I completely believe their whole metabolism theory, but so far it appears nutritionally sound and safe. Although 1400 cal (let alone 1200!) is WAY less than I've been eating.
But I've lost 5 lbs. already. I'm telling myself I shouldn't weigh every day because that will be misleading/demotivating. But MAN, it is tempting! Monday I kick up a couple of hundred calories, so we'll see what happens.
