Trying To Eat Less Becomes More Important To Fend Off Middle-Age Weight Gain ““Because the body's energy requirements progressively decline with age, energy intake must mirror that decrease or weight gain occurs,” said Davidson, a research fellow at Columbia’s Obesity Research Center. “Dr. Tucker's observation that women who practice eating restraint avoid the significant weight gain commonly observed in middle age is an important health message.” Tucker says watching what you eat is not about physical appearance – it’s a direct investment in your health. “Weight gain and obesity bring a greater risk of diabetes and a number of other chronic diseases,” Tucker said. “Eating properly is a skill that needs to be practiced.”“

Clinical Guidelines

ASSESSMENT AND TREATMENT OF OBESITY AND OVERWEIGHT IN ADULTS (Guidelines)

Guidelines Updated for Physical Activity Intervention for Weight Loss “Recommendations for PA are 150 to 250 minutes per week to prevent weight gain and more than 250 minutes per week for significant weight loss and weight maintenance after weight loss. There is inadequate evidence of recommended PA for prevention of weight regain after weight loss. • Resistance training is linked with reduced health risk, possible increased fat-free mass, and increased loss of fat mass, but not weight loss.”

Effects of exercise and diet on chronic disease. (J Appl Physiol. 2005) "Overwhelming evidence from a variety of sources, including epidemiological, prospective cohort, and intervention studies, links most chronic diseases seen in the world today to physical inactivity and inappropriate diet consumption. The purpose of this review is to 1) discuss the effects of exercise and diet in the prevention of chronic disease, 2) highlight the effects of lifestyle modification for both mitigating disease progression and reversing existing disease, and 3) suggest potential mechanisms for beneficial effects."

"Eco-Atkins" diet lowers heart risks: study “The traditional Atkins low-carb diet, in which people cut out carbohydrates and eat more meat, has been shown to help lower blood fats known as triglycerides and raise high-density lipoprotein cholesterol or HDL, the "good" cholesterol, but it also tends to raise bad cholesterol levels. Jenkins and colleagues looked to see if a vegetarian version of the Atkins diet that was high in vegetable proteins from gluten, soy, nuts, fruits, vegetables, cereals and vegetable oils might have more heart benefits. … After a month, people in both groups lost about four kilograms, or 8.8 pounds. But people on the low-carb, plant protein diet had lower LDL cholesterol and healthier blood pressure compared with those on the high-carb diet. Jenkins said the study suggests a plant-based low-carb diet may be an effective option for people with high cholesterol who want to lose weight.”

Moderately Reduced Carbohydrate Diet Keeps People Feeling Full Longer “When carbs are eaten and digested, they change into sugar. Before and after the meal, the researchers measured the subjects' levels of insulin and circulating glucose (nonfasting blood sugar) and asked them to rate their hunger or fullness. They evaluated insulin response to a meal and blood sugar levels, because lower insulin and stable blood sugar levels may contribute to increased feelings of fullness, Gower explained. Their research showed that, even in the absence of weight loss, a modest reduction in dietary carbohydrates was sufficient to lower insulin and stabilize blood sugar after a meal. Ratings of fullness were higher in the group on the moderate-carb diet before eating breakfast and stayed higher for a longer time after the meal, compared with those eating the standard diet. "Over the long run a sustained modest reduction in carbohydrate intake may help to reduce energy consumption and facilitate weight loss," Gower said.”
