Weight is never a good measure for health. Many people refrain from doing what;s best for them because they're too heavy or too thin. I've had people do the LifeForce Plan and lose more weight than they wanted to, but they eliminated life-long problems. Along the way, they improved their digestion and therefore improved their ability to breakdown and absorb more nutrients.
I've also had people with many digestive problems and severe inflammation not do the Plan for fear of losing weight. They stay in a downward spiral. If your program is working for you stick with it. There are some products like Immunocal that may be able to help. Immunocal was shown to help AIDS patients in gaining weight when nothing else helped. Super Sports amino acids has also helped some people when they also used exercised in conjunction with the supplements.
Colonics can be helpful with skin conditions. Organic shampoos, soaps, conditioners, lotions, etc are helpful. A shower filter is another good idea.
