carbs arn't bad... you really need carbs
from everything I've read it says just to exercise and limit the amount of fat you ingest...
it takes a 3500 calorie deficit to lose 1 lb
so, 500 calorie deficit a day and you've lost a 1lb that week (meaning you burn 500 more calories a day than you consume)
you can do that with eating less but th ebest way is to eat slightly less and exercise (cardiovascular exercise)
this will get your metabolism up and make you healthier
carbs give you the energy that you need to exercise
if you didn't eat anything and tried to exercise you'll bonk and it'd be a waste... but if you ate your carbs and had energy you could exercise all day, and that's better for you (well not all day literally but exercise is better for you)
you don't want to lose more than 2lbs a week, so you'd never want more than a 1000 calorie deficit a week
I've lost 35 lbs and I've kept it off for a few years, so this strategy has worked for me. I just cut out things like whole milk (drink skim now), butter, sugar on my cereal, mayonaise, soda
just remember, "carbs are the fuel for the flame on which fat burns"
