How can you say that the diet is healthy?

A healthy diet has to have a balance of healthy foods,make sure you get a little of all the pyramids food groups. If you are doing less meats then substitute your meat proteins with peanut butter,eggs,tofu,other proteins even protein shakes. When I go healthy I add yogurt,fresh/frozen veggies(no canned) and fresh or frozen fruits(no canned) and go for only lean meats. Someone could lose atleast up to 7-10 the first week if not more depending on how much you have to lose. I also cut out pop totally and cut back on sugar alot. And kick up the exercise a notch. Hope somehting helped.. and good luck.

In fact everyone has a different health condition. Some foods are harmful to one person but helpful to the other. Someone need little nutrition while some others need much more nutrition to live a healthy life. And different growing stage needs different quantity and quality nutrition. So I don't think vegetarian is suitable for everyone.

I think that you should seek the advice from a registered dietitian. I know that a vegetarian lifestyle should be the healthiest but that wasn't the experience of a very close friend of mine. She went on a vegetarian diet and about a year later she was so tired that she could barely get out of bed. She would be up for a couple of hours and then she would have to take a nap. When she went to the Doctor, she learned a couple of things that could have prevented all of that. First of all because she didn't eat meat, he told her to supplement her diet with an iron supplement and vitamin B12 shots. She learned that she'd developed a severe yeast infection that spread through her body because of the kinds of food that she was eating. For three months, she had to eat a form of protein, rice and vegetables in equal quantities for all meals. Once she was better, she went to a dietitian and her diet is now raw foods. Good luck to you.
