12. Ice Diet

We can all agree that water is helpful when it comes to losing weight. But this doesn’t mean that water can help you lose weight no matter what form you consume it in.

That’s where Renee Zellweger comes in. She claims that eating ice helps her suppress the feeling of hunger, as if she was actually eating food.

This diet is so extreme that experts went as far as marking this diet as completely unhealthy and inefficient.

When asked about her weight loss method, the actress said: “As long as I get that ‘constant feed’ feeling, it’s semi-tolerable.”

Good for you, Renee, but we would rather go for some cabbage soup or lemon juice.
