My teenage daughter is on some low carbohydrate diet these days, and I am quite perplexed about this plan, as I have never come across a diet, in which one stops taking milk, and even fruits! I understand that carbohydrates is one of the major nutrients in food, so why is it that its less amount helps in reducing weight. I would really be grateful to you guys if you can help me with an insight of carbohydrates in food, and its efficacy in reducing weight. Thanks.
