A healthy diet should include foods from the four main food groups. One of the best ways to lose weight is to follow the food pyramid and eat the suggested servings of each food group for your age. This method of healthy eating does require planning and you need to have a copy of the food pyramid in front of you as you plan your menu for the week. Planning a weekly menu is a good way to get started and once you do this for several weeks, the kinds and amounts of foods that you should be eating will soon become clear to you.

Although junk food is a no-no when you are on a diet, many people who do eat healthy foods still indulge in their favorite snacks from time to time. There is nothing wrong with treating yourself from time to time as long as you don't make it a practice or overindulge. There are also differences in what vegetarians term "healthy foods", so if you don't eat meat, it does mean that you exclude all animal proteins from your diet. Proteins are essential nutrients that vegetarians might be at risk of not getting unless they pay particular attention to their foods.

Soy is comparable to animal protein and should be included in a daily diet if you are a vegetarian. Other sources of protein include

* Dry beans
* Peas
* Lentils

Some grains and vegetables are also good sources of protein. Soy milk and tofu are good sources of calcium and green leafy plants are a good source of iron.

Even if you are not a vegetarian, these foods will help to complement your diet and help you to feel full. All dieters should include a multi-vitamin and mineral supplement just to make sure. Drinking at least 8 glasses of water a day helps to flush out the burned calories and keep your body functioning the way it should.
