Sorry for the randomness of paragraph ordering here. These are a bunch of loosely related thoughts.
Okay, first of all, if you're exercising, you need carbs. Of course, you know that already.
My husband saw a report on TV today that the vast majority of people who do the low-carb thing gain the weight back, plus some, after 15 months or so.
Me, I'm suspicious of just about anything with the word "diet" in it, especially when you're living an active lifestyle. But there is one thing that every medical professional endorses: exercise. If you're not working out, you're not going to be healthy.
A true low-carb, Atkins diet works by changing your metabolism. It's a lifestyle change from omnivorous to carnivorous, and as little as one pancake breakfast will put your metabolism right back where it started. As such, Atkins is particularly ill-suited for short-term weight loss. And most people who think they're eating low-carb actually aren't -- it's really tough to do.
Are you sure that your weight gains are fat, not muscle?
I've seen steady, but very slow, improvements to my health and fat content by eating lots of small meals, vastly upping my raw fruit and veggie intake, and generally trying to eat foods that are lower in fat. Oh, and lest I forget, working out more.
I know that caffeine is an appetite suppressant -- don't know of its effects on the metabolism. Personally, removing caffeine from my diet has given me much more energy (after getting over withdrawal!) and generally been a big plus.
