Often when one is losing weight and working out, it can appear on the scale that nothing is happening. This is because you may gain lean mass while losing fat mass.
Below are two pictures, one taken today and one yesterday, of women who have started light exercise programs while following an Eatstrong nutrition plan. Note the fat loss and the lean mass gain:
While some people may argue this looks slow, note that each of these women are ONLY losing body fat, and actually gained lean mass. This is actually slightly faster than I like to see people lose. Remember: they are note counting calories or limiting portions.
