If you're female, postmenopausal and sedentary, you have three reasons to keep reading.Here's why: you're at increased risk for osteoporosis. Luckily, there's a few things you can do about it.

1. Gain weight: Yes, it's true. Tipping the scales will increase the load that your bones have to bear. In the world of bone making, load = growth. That said, I'm not advocating a bacchanal and binge fest. Being underweight, small-framed and light footed increases your risk for developing brittle bones. However, getting fat is not the best solution, considering the side effects (heart attack, stroke, diabetes...)So I repeat, although gaining weight will help with bone density, I do NOT recommend it. For the love of your body, don't pull out the kettle corn and start watching a Twilight Zone marathon.

2. Exercise: This, is by far, a better choice than trying to gain so much weight you can file for disability (a la Homer Simpson). Unlike obesity, exercise can stimulate bone growth without causing 50 adverse side effects. All exercise is not created equal, though. You need to make sure it's "weight-bearing." Examples include running, walking and weight-lifting, all of which put stress on your bones and lead to increased growth.

3. Eat right: Milk, cheese, yogurt, green leafy vegetables (marijuana is not a green leafy vegetable), nuts and various beans contain calcium, essential for bone formation and maintenance. If you're part cow and like to graze, you're already set up to succeed. Just go for the kale, collards and spinach. If you're not into the greens try dairy but make sure you stay away from the frozen, creamy stuff (putting it on top of a split banana doesn't make it less fattening). If your diet doesn't take you far enough, make sure to add a calcium supplement, especially if you're pregnant or over 50.
