A Star Diet Secrets insider reveals that Hayden Panettiere may consider taking on a vegan diet. Quite a few stars turn to vegetarian diets as a way of losing weight. Trouble is, most of these stars don’t realise that giving up meat makes it much more difficult to eat a healthy diet.

So if you stop eating meat, you need to eat a wide range of vegetarian foods to compensate for this deficiency. Unfortunately, most vegetarian stars are not famous for doing this. Enough said.
