Eat less ; exercise. The key to losing weight is not a temporary diet but permanent changes. Sugars ; simple carbs from grains esp. Cause weight gain. It's also wise to avoid fried foods. I like dr. Furhman's diet: http://bit.Ly/1dhw9ht dr. Weil has useful info: http://huff.To/19ygs8y- see his "discuss that" link in his article. Exercise is also important! it's also best to choose organic foods:http://bit.Ly/19x.
Reduce weight. This is a repeat of what I have said before. My philosophy is that the best way to lose weight is not by dieting, but by changing your lifestyle to a healthier one. You don't need a drastic diet. Make small changes. Eat the right portions, eat 3-5 small meals a day, cut back on carbs and sugars, increase lean protein/veggie/fruit/water intake, and start doing some cardiovascular exercise.
