Live Active Keto Some people have made statements against the South Beach Diet. Some claim it is too expensive; others say that it is hard on the body. My response to these accusations is that there is nothing too expensive if it keeps my family and I healthy. Also, by cooking yourself instead of buying prepackaged meals you can save money. While purifying your body may seem tiresome and costly at first the results will be tremendous. You'll feel better, look better and your family will be healthier.
