There are many (not here in the forum but 'oot there) who use LC diets just for weight loss. Most give up because they do not see the weight falling away like on other Low Cal diets they are used to. But, the problem with massive weight loss, impressive as it may be at first, is that when the diet stops, the weight just piles on again, and they suffer rotating door syndrome.
LC weight loss that is more gradual tends to be not just the water loss that crash diets use to impress us, but is more mellow, and less roller coasting. I have been LC for over 5 years now. My weight dropped from 18 stones steadily down to 10 stone, and I have remained fairly steady at that weight for 4 years at least. I sometimes shake the scales in case the pointer is jammed, but no. 62.3 kg repeatedly every week give or take half a kg.
