I read an article on a fitness/nutrition website that said something similar. When you don't eat enough calories, you body thinks that it is starving and you will lose no more weight. Of course, I only read an article online so I'm not really qualified either.jptaylorsg said:How much are you exercising?
It's possible you might not be eating enough.
At your weight, with daily vigorous exercise, you probably need 2400 calories or more.
If you're not eating enough, your body will go into starvation mode and stop burning as many excess calories.
Like Haiku said, eat several smaller meals and eat healthy, but try to make sure you're eating enough.
