I think that the best plan out there is Weight Watchers. For some people it is a plan to loose weight but it also shows you how to eat healthy. The plan shows you true portion sizes, lets you eat from all of the food groups, so you have a very balanced diet and most importantly you can enjoy desert! My sister in law is a jazzercise instructor and she uses the plan for healthy eating.

The best way to stay healthy and ditch the heart attack is to go vegetarian. It sounds hard but it extremely easy. Just ditch the meat. There are tons of wonderful recipes. Just give it a try. :)

volumetrics or weight watchers really any weight plan gets you healthy

Quite likely you have been overdoing the fruit and vegies component of the vegetarian diet. Besides fruit and vegies you need some solid foods as well. Plenty of cereal, muesli, bread and hot pasta and, of course, nuts such as almonds can all be included in a vegetarian diet. Fruit and vegies alone is not recommended.
You need to do some research and searches of the type "vegetarian diet" + health may help to improve your vegetarian diet if you wish to persevere with it or modify it.

To look and feel your best, you need to eat a balanced diet. Eat 5 times a day. That includes a mid morning and afternoon snack. Try and go 40/40/30. protein/carbs/fat. Follow something like what is outlined in the book Body for Life or The Zone. It lets you eat real food and you won't go hungry.
