As someone who's struggled with my weight all my life, I've had my share of successes and failures with keeping myself looking and feeling healthy.
Lately, (as many of you know) I've become a vegan/raw food advocate, because I personally feel it's the way things are meant to be. But I love to do tae bo (have been doing this for years), and I've been doing a lot of Kathy Smith's weight resistance regime. I'm a huge exercise advocate, not just to control your weight, but because it's important to be active and keep yourself toned. Plus, if it makes you feel good, then it has to be good!
To feel healthy, you need to watch what you eat, and understand what food does to your body. Don't go into those weight loss programs, and have other people do the thinking for you. You have to learn and understand the effects of food to your health. Education is the key.
And find an activity that you love to do, to keep yourself active and feeling great.
Don't believe what all those starlets are saying out there. To keep themselves looking good, they either exercise obsessively or eat hardly anything at all. Plus, they spend thousands of dollars on botox, liposuction and collagen impants, and then lie about it. That's not real, and that's not healthy.
Also important - you should be looking good and feeling healthy for yourself. You don't need to do it for other people. It's about how you feel, not what others think.
