A new study about the best way to beat belly fat. Dr. Jen Ashton is here to talk about it. It's not just exercise, but the kind of exercise. Exactly. This was a large study out of Harvard, looked at middle aged men, followed them for 12 years. The men who lifted weights for more than 25 minutes a day gained less fat. It sounds like a lot. It is a lot. But a lot of people are trying to get a little bit of a workout in every day. They found the men who engaged in hard cardio gained less overall body weight, but the waist circumference was a surprise. You think lifting weights is going to build up your arms or legs, but it's core. Why not a combination of both? That's the ideal. Physiology, two things. As we age, everyone loses lean muscle mass. That's not create for our health. The other thing that happens as we age, get a little wider around the midsection. The belly fat, that's bad for us. To find an exercise that does both, that's the key. And the fact that the weights helped the weight circumference was surprising. What types of exercise, and it this the same for women? Great for men and women. You need to pump iron. We need to get into the gym, lift weights, and you can do a little bit every day, that's important. Cardio, you have to get your cardio on. That's important for cardiovascular well-being as well as body fat. And the other thing is good nutrition. None of this matters if we don't eat well. That's kind of a no-brainer. But the lifting weights to combat the mid-section. Get into the gym. Another thing to add. Thanks very much.
