Fighting belly weight

It's no secret that being obese can increase your risk of heart disease, but now research shows the extra weight in your belly puts you at the biggest risk. The fat that gets deposited around your abdomen is different from the fat in your hips or thighs. It is more biologically active, causing calcium buildup in your arteries.

Stay on top of your weight with these tips:

1) Don't focus on BMI: Sometimes your body mass index (BMI) places you in a healthy weight range despite the added inches around your waist. The best way to measure is to take a tape measure to your waist - around the belly button, then hips. The key is for your waist to be smaller than your hips.

2) EAT!  Yes, eat. The best way to get your metabolism moving and lose weight is to eat frequently - small meals every 4 to 5 hours. Also, never skip breakfast. Studies show people who eat breakfast lose more weight and burn more calories than those who do not.

3) Get moving: Exercise is still the best way to maintain a healthy weight long-term. Try to fit in some sort of daily activity. Don't have an hour? No problem! Split up activities into shorter periods of time throughout your day and reap the same benefits.

Losing as little as 10 percent of your current weight will help to lower your risk of developing heart disease.
