Extreme diets don't work.
Even if you're thinking 'I just want to go on a really strict diet, lose some weight, nice and healthy..' you could easily get stuck in that mindset. That's what happened to me and now, five months on, I have an eating disorder.
Stay out of the world of extreme diets and calorie counting. It's safer just not to look at it at all.
Not eating, or drastically eating less = quick weight loss, then binging, years of yo-yo dieting, slowing down the metabolism, and ultimately ending up weighing more than you ever have.
Exercise, a controlled, healthy diet, 2,000 calories a day = gradual, healthy weight loss that is easier to keep off.
