Dear Lifehacker, Are detox diets good for you, or just another pseudo-science? Does your body really build up toxins that affect you health and does a detox get rid of them?

Water: refreshing. Lemons: also refreshing. Combine the two, and you get a drinkable liquid with sprightly flavour. That is all you get. Not a detox elixir, not a metabolism booster. Let me repeat: when you add lemons to water, you just get lemon water. (And if you also add sugar, you get lemonade.)

I try to eat healthy. I really do. But if I haven't planned ahead and don't have a healthy meal in the fridge, I could end up eating anything. I won't go into detail except to say that one time I had cookies for dinner right before rushing off to teach a nutrition class. I'm not proud.
