Exercise and Obesity

March 28, 2023 Whole grains don’t contain a magical nutrient that fights diabetes and improves health. It’s the entire package—elements intact and working together—that’s important. The bran and fiber in whole grains make it more difficult for digestive enzymes to break down the starches into glucose. This leads to lower, slower increases in blood sugar and insulin, and a lower glycemic index. As a result, they stress the body’s insulin-making machinery less, and so may help prevent type 2 diabetes. Whole grains are also rich in essential vitamins, minerals, and phytochemicals that may help reduce the risk of diabetes.  In contrast, white bread, white rice, mashed potatoes, donuts, bagels, and many breakfast cereals have what’s called a high glycemic index and a high glycemic load.  Simple Steps to Preventing Diabetes | The Nutrition Source | Harvard T.H.

March 20th, 2023 March 20th, 2023 "A team at the University of Exeter in the United Kingdom studied 300 children as they aged from 9 to 16 and found those who were more active at age 13 were less likely to develop insulin resistance. Oddly enough, increased exercise provides no benefit at the age of 16, the study, published in the journal  Diabetologia , concluded. Brad Metcalf, Ph.D., a senior lecturer in physical activity and health at Exeter, said insulin resistance peaks at age 13. Reducing it, he said, could lessen the demand on insulin producing cells and preserve them for longer. “We’ve identified a critical window when activity has the biggest impact on adolescent insulin resistance,” he told Healthline. “What now needs to be identified is an intervention/initiative that actually increases time spent being active by at least 15 minutes a day.” Exercise Helps Young Teens Lower Diabetes Risk (healthline.com)

March 9th, 2023   "A large body of observational data show an association between higher levels of physical activity and lower rates of many chronic diseases. Conversely, physical inactivity is a component of reduced life expectancy. The energy expended by physical activity is a component of energy balance that is particularly important in the pathogenesis of obesity and in its treatment. The components of energy expenditure are resting metabolic rate (RMR), the thermic effect of feeding (TEF), and physical  activity. The management of overweight and obesity includes a combination of dietary changes, increased physical activity, and behavior modification".

  "Despite all the health benefits of physical activity, people worldwide are doing less of it-at work, at home, and as they travel from place to place. Globally, about one in three people gets little, if any, physical activity. ( 1 ) Physical activity levels are declining not only in wealthy countries, such as the U.S., but also in low- and middle-income countries, such as China. And it’s clear that this decline in physical activity is a key contributor to the global obesity epidemic, and in turn, to rising rates of chronic disease everywhere."

  Feb 7th, 2023 Keeping active can help people stay at a healthy weight or lose weight. It can also lower the risk of heart disease, diabetes, stroke, high blood pressure, osteoporosis, and certain cancers, as well as reduce stress and boost mood. Inactive (sedentary) lifestyles do just the opposite. Physical Activity | Obesity Prevention Source | Harvard T.H. Chan School of Public Health
