How can I loose belly fat with out doing exercise I have been doing 100-150 sit-!

You can't loose weight by just doing sits up. To loose weight you need to follow strict regime of exercise and follow a healthy diet and surely you will see the results and will loss weight. http://thewikihealth.blogspot.com/2011/0… here are some simple tips that will surely help you to loose weight early and also maintain so that it won't grow later on.

I may need to know more details about what your exercise regime is but here is what I imagine is happening.

The fat around your belly is the same as it was the day you start (or maybe slightly reduced) but with the amount of sit ups you are performing you are growing more muscular as well "under the fat". This pushes the fat out further and makes you look "fatter" while you are in fact fitter.
Eat heathily will help out and try to have a good all round exercise regime. When in doubt perform more squats.

I'm looking to start the Lemonade Diet, and that's ment to help you loose weight and flab around your stomach, and other areas because all you consume is lemonade drink for a minimum of 10 days to get results.. Type lemonade diet into google and you will find out everything about it.

i did by following this

In order to lose weight, you have to exercise AND eat healthy. (and sweets in moderation, of course :))

well if you still eat a bunch of crap food then just doing situps wont help you...
