They can be expensive when you add the cost of membership with the expense of eating the packaged meals and using the special supplements. Conventional methods are generally safer and are backed by research that proves their health benefits. These include vegetarianism, the Dean Ornish and the Dr. Pritikin diets, low fat diets and exchange pattern diets. The percentages of carbohydrate, protein and fat that these diets provide varies dramatically, and this is where consumers get confused. These plans usually work when you match the right person with the right diet.
Some people naturally gravitate to the style of eating that best supports their energy and stamina.
Some thrive on fresh fruits, veggies, whole grains and plant protein, while others feel terrible unless they eat red meat and animal proteins. As a dietitian, I strive to match the right person with the right diet. For example, if your family history is positive for cancer, and you also have heart disease, it is amazing how the right diet can support prevention of both conditions at the same time. I think people worry that health conditions each have their own modifications, but often, one set of guidelines help the whole body which puts nutrition into a holistic context. Exercise is extremely important, too.
