Transcript for New Studies Show Impact of Exercise on Type 2 Diabetes
First, though, we've got that new health headline about diabetes and exercise and why when you work out really matters. ABC's chief health and medical editor Dr. Richard Besser joining us now with that and let's say we're talking about type 2 diabetes. Exactly, exactly. You got nearly 10% of Americans have this and one this three are sort of so-called prediabetics so that's a lot of people right there. How much exercise do people need to reduce this risk. So this is really interesting. They looked at 28 studies that followed thousands of people over many years to try to address that and what they found was if you do the 30 minutes five times a week which is recommended, it greatly reduces the amount -- your risk of getting type 2 diabetes. If you do more than that your risk goes down even further but what really grabbed me was that if you do less, if you do only ten minutes a day you get some benefit compared to people who do nothing so every bit helps. You shouldn't be put off by the fact I don't have enough time. More is more and timing was also very important in the study, correct? So, a separate study looked athe people who have type 2 diabetes. You got your 30 minute, do it as one block or break it up. So they had people for one period of time do it in one block of 30 minutes and the other they did ten minutes right after eating a meal and when they found if you do the ten minutes just go for a ten-minute walk after you eat your meal it greatly reduces blood sugar, 22% lower blood sugar with just a ten-minute walk. The science behind common sense. Is that just because your engine so to speak is working and processing food better. Walking helps you digest but it's controlled by ins win and when you exercise it helps our cells use the insulin and also causes our muscles to burn up that sugar so, you know, there's good reasons for why that bounces out your sugar and a great thing to do. In addition to exercise what else can people do. We talk about it all the time. If you can maintain a healthy weight or if you're overweight losing just 5% of your body weight, that's enough to dramatically reduce your risk of having type 2 diabetes. It's hard to do but it's really worth that effort. All of it doable too. It is. Even a little bit of exercise. Even a little bit of weight. Getting a partner for both of those is a great way to get started. It really helps your chances of succeeding. Good information. Thanks. Coming up we'll hear from
