What's more, decades of research show that obesity leads to many serious health problems. These extra pounds make you more likely to get a wide range of diseases, from diabetes and high blood pressure to dementia and some kinds of cancer. Going up just a single skirt size over any decade between your mid 20s and mid 50s, for example, makes you a third more likely to have breast cancer after menopause.
The health problems tied to obesity, especially chronic diseases like diabetes, can have a long-term impact.
"These are diseases you have to manage not just for a few months, but for a lifetime,” says dietitian Rachel Brandeis. “They impact your health, your wallet, and your day-to-day activities. You spend more time at the doctor’s office and more money on medication. You’re always trying to manage your disease and feel better." What's at stake, she says, is your quality of life.
Still, many of us have a hard time facing our weight. Brandeis says most people are "shocked" when they step on the scales.
3 Game-Changers1. Know your BMI and waist size.
Your body mass index (BMI) is based on your height and weight. It’s a good tool to help measure body fat – and gauge your chances of disease. But it isn’t foolproof. If you're muscular, the BMI can overstate your body fat. If you're older and have less muscle mass, it can understate your body fat. BMI is just a guess at the link between your weight and health, says Sally Stieghan, a registered nurse and dietitian from Atlanta.
Your waist size can give a better picture of your health – especially if you’re muscular. Simply take a tape measure and put it around your waist, right above your belly button. If your waist size is over 35 inches (for a woman) or 40 inches (for a man), it's time to take some action.
