Bad Breath

[siouxsie2007]

Why is it that everytime I am on a diet (doesnt matter which diet) I have really really bad breath.

Normally when I eat junk, my breath is okay

Do you diet hard? Often if you go on a very restricted diet, whether restricted calories or restricted range of foods, your body changes the way it metabolises food and gives you bad breath. I think it's called ketosis, and can be avoided by dieting gently and eating a wide range of foods. I think also that having too great a proportion of protein (relative to fats and carbs) in your diet can cause this.
