had a quick question on weight loss... how fast is too fast to lose the weight and when do people usually hit weight loss walls after they start a diet or do they?.. ive lost 14lbs since last thursday and ive lost an 1/1/2 inches on my waist but my bodyfat percentage hasnt went down? is that normal? i did some forum searching but nothing came up so hope im not beating a dead horse with this post any help is much appreciated ...
