ORIGINAL: KurtGranz But diet alone can keep people at a healthy weight. I'm going to comment on this ONE line from your post, from a medical perspective. Diet alone can keep SOME people at a healthy weight, but not all of them, and weight alone is not the most significant factor in sustained -health-. If you've -ever in your life- worked out and built substantial muscle mass, diet alone will -never- keep you at a healthy weight again, unless you continue to exercise. If you stop exercising, your muscle mass will diminish, and your metabolism will slow (something that also happens automatically, as an individual ages, unless they exercise to offset the normal metabolic slowing of age). For some people, this slowing of the metabolism shows itself in things like loss of bone mass, thinning of skin and hair, and poor metabolism of materials that support things like the cartilage and bursal sacks in the joints. For others, especially those who have built considerable muscle mass, slowing metabolism results in adipose collection -- especially around the belly, chest and upper body (the most dangerous area for fat collection). In still another group, metabolic changes result in loss of organ mass and poor resiliency in things like the blood vessels, heart, lungs, and in reduced regeneration of the liver. There is a point to doing everything you are willing to do to stay healthy, but obsessing about it isn't health producing. In fact, stressing about health and obsessing about fitness activities can actually be -counter productive-. Increased levels of cortisol are released during stress. Normally, exercise that is -enjoyed- will reduce cortisol levels in the bloodstream, but stressing about getting to the gym, working harder and longer, and the frustration of working hard at your body and still not getting the body you want will actually increase cortisol production -along with- increasing muscle mass, resulting in intramuscular fat (what is called "good marbling" when you're talking about steak) that will actually reduce lean-muscle mass in the body. So... diet alone won't do the trick, and neither will stressing about whether you're working out enough or whether your workouts are going to make you look like Jill Ireland or The Rock -- and whether looking like that will get you a girlfriend/boyfriend or whether you're going to be alone for the rest of your life. Enjoy your life. If you hate it, get rid of it. If you love it, keep doing whatever you're doing. LZ
