Eating Only Within 10-Hour Period Fights Fat
LOW-CARB DIETS ARE DANGEROUS Low-carbohydrate diets — high in protein and fats — are often used to lose weight, but a Polish study found that long-term use increases the risk of premature death. “Risks were also increased for individual causes of death including coronary heart disease, hypertension, Type 2 diabetes, stroke, and cancer,” said study author Maciej Banach. “These diets should be avoided.” Compared to middle-aged people who ate the highest amounts of carbs, those with the lowest intake had a 32 percent higher risk of overall death and a 51 percent higher risk of dying from coronary heart disease over the six-year follow-up.

imiting eating to a 10-hour period every day can protect against obesity and metabolic
disease, even when the diet is high-fat, say scientists at the Salk Institute. They discovered the technique was effective even when mice lacked the biological clocks that were previously thought to be essential for a healthy metabolism. Their research suggested that health problems associated with eating throughout the day or doing shift work can be corrected by eating all daily calories within a 10-hour window. In a previous study, normal mice that were allowed 24-hour access to a high-fat diet became obese and developed a wide range of metabolic diseases, including high cholesterol, fatty liver disease, and diabetes. But when their eating was restricted to a daily 8- to 10-hour window, they became lean, fit, and healthy. The current study examined mice that lacked the genes for biological clocks and were therefore predisposed to being morbidly ill. Those allowed a high-fat diet around the clock became obese and developed metabolic disease, while those that ate the same diet and number of calories during a 10-hour window remained lean and healthy.
High-Carb Diets Lead to Weight Loss D
iets high in carbohydrates cut body weight and body fat while improving insulin function in overweight people, says a study published in Nutrients.
The key, however, was that the diet was vegetarian. The 16-week randomized clinical trial tested a high-carb, low-fat, plant-based diet against trial participants’ normal diets. Those eating the high-carb diet avoided foods containing animal products, added plant-based oils, and limited fat intake to 20-30 grams per day, but observed no limits on calories or carbs. At the end of the trial, there were no changes in the controls, but the plant-based group showed a significant decrease in weight, body mass index, fat mass, visceral fat, and insulin resistance.

cause changes in the gut’s microbe that can improve the regulation of glucose in the liver, according to Penn State scientists. Mushrooms were given to mice in amounts that were the human equivalent of three ounces. The mushrooms served as probiotics and set off a chain reaction in gut bacteria that changed the expression of genes that help manage glucose production. The scientists hope their findings will lead to new treatments for diabetes.
ALZHEIMER’S: WORSE IN WINTER The severity of Alzheimer’s symptoms
varies with the seasons, says research published in PLOS Medicine, which found that cognitive skills are better in the late summer and early fall than in the winter. The difference in thinking skills was almost five years in age-related decline. Researchers also found variations in levels of Alzheimer’s-related proteins in cerebrospinal fluid and genes in the brain.
APPENDICITIS: ANTIBIOTICS CAN CURE New Finnish research published in the Journal of the American Medical Association found that taking antibiotics for appendicitis instead of undergoing immediate surgery is a realistic choice for most patients. Surgery is only necessary in cases where the appendix has ruptured, which can be seen on a CT scan. The study found that 70 to 80 percent of patients can be treated with antibiotics.
HEADACHES: VITAMIN D SLASHES MIGRAINES Taking vitamin D supplements can cut the number of migraines in half. Randomized, placebo-controlled research from Denmark’s Aalborg University studied adult patients aged 18 to 65 with migraines. Patients took either 4,000 IU of vitamin D3 daily or a placebo pill. At the end of 24 weeks, the number of migraines in those taking vitamin D declined by 50 percent, although the severity of migraines remained the same.
