1. Eat only what your body actually needs. Would you stuff sugar in your car's gasoline tank? Give a bowl of it to your cat or dog? No? Then why put it inside your mouth? Sure it tastes good. Kind of. But it isn't doing you a bit of good. We need to forget about all the external reasons for eating (taste, appearance, smell, texture) and focus on what our bodies actually require to work properly. No, we don't have to turn into Seven of Nine; but we can learn to like things that are actually good for us.
2. Move. If you sit all day, you're doing yourself a huge disservice. Bodies weren't meant to stay in one place all day. You have to move. There is a dynamite article in the April, 2008 edition of Nutrition Action called "Chair Today, Gone Tomorrow," that I urge everyone to read. The bottom-line is that you don't have to run marathons or sweat a lot. You just need to move. Walk on your treadmill at 1.5 miles an hour while you read or talk on the phone. take the stairs. Go window shopping. The bottom line is that any kind of movement is better than no movement at all.
And yes, I'm doing it. Got plans to make my whole house more suited to my body's needs.
