I am on Atkins diet.
Basically I am eating only meat. (Almost) No vegetable, no fruits, no bread, no rice, no sweets.
YES YES I know this diet will horrify some people and yes I know it is not very healthy. But it is effective and I will come off it slowly and start eating vegetables and fruits. But so long as I am on such a diet, I think I need to take Vitamin (and Fiber) supplements.
