I'm just really concerned you're not eating enough haha, and when your body goes into starvation mode it destroys your metabolism and all your effort will go to waste
Basically you need to find out how much your body is burning a day naturally, through your life style and subtract 500-1000 calories from that. 500 calories=1 pound of fat loss a week whilst 1000=2 pounds. This is pretty much the standard for healthy weightloss.
You can use this calculator, should be able to walk you through it. If you need anymore help, just ask
(you need an account to see links)
