Insulin Resistance News and Research

RSS

Insulin Resistance is a condition in which the body does not respond to insulin properly. This is most common in Type II diabetes or associated with obesity, ketoacidosis, infection, and certain rare conditions. Diminished effectiveness of insulin in lowering blood glucose levels requiring 200 units or more of insulin per day to prevent hyperglycemia or ketosis.

Study compares exercise regimens for obese older adults

Sedentary, obese older adults appear to improve their functional abilities and reduce insulin resistance through a combination of resistance and aerobic exercises, according to a report in the January 26 issue of Archives of Internal Medicine.

Low-carb diet burns more excess liver fat than low-cal diet

People on low-carbohydrate diets are more dependent on the oxidation of fat in the liver for energy than those on a low-calorie diet, researchers at UT Southwestern Medical Center have found in a small clinical study.

Fatty liver disease medication may have no effect

A new randomized, prospective trial has shown that orlistat, a commonly prescribed inhibitor of fat absorption, does not help patients with fatty liver disease (FLD) lose weight, nor does it improve their liver enzymes or insulin resistance.

College-age football players who gain weight to add power to their blocks and tackles might also be setting themselves up for diabetes and heart disease later in life, a new study suggests.

Metabolic syndrome risk for veterans with post-traumatic stress disorder

Veterans with post-traumatic stress disorder (PTSD) are more likely to have metabolic syndrome than veterans without PTSD.

People with Ala12 gene variant need to watch out for high fat in their diets

New evidence in mice bolsters the notion that a version of a gene earlier shown to protect lean people against weight gain and insulin resistance can have the opposite effect in those who eat a high-fat diet and are heavier, reveals a report in the January 7th issue of the journal Cell Metabolism, a Cell Press publication.

Novel treatment option for obesity

A new study in the January 7th issue of Cell Metabolism , a Cell Press publication, helps to explain why obese people and animals fail to respond to leptin, a hormone produced by fat that signals the brain to stop eating.

Continuous positive airway pressure improves sleeping glucose levels in type 2 diabetics with obstructive sleep apnea

A study in the Dec. 15 issue of the Journal of Clinical Sleep Medicine suggests that screening type 2 diabetes patients for obstructive sleep apnea (OSA) and treating those who have OSA with continuous positive airway pressure (CPAP) therapy could improve the management of their hyperglycemia and might favorably influence their long-term prognosis.

Fatty liver disease and body shape

For years, pear-shaped people who carry weight in the thighs and backside have been told they are at lower risk for high blood pressure and heart disease than apple-shaped people who carry fat in the abdomen.

Adropin protein produced by the liver sends signal that fat is on the way in response to high-fat foods

After you eat a burger and fries or other fat-filled meal, a protein produced by the liver may send a signal that fat is on the way, suggests a report in the December issue of the journal Cell Metabolism , a Cell Press publication.

Bariatric surgery may resolve liver disease

Obesity is a growing epidemic in the U.S. with a significant increase in prevalence from 15 percent to 32.9 percent from 1980 to 2004.

Vitamin K appears to slow development of insulin resistance in elderly men

Vitamin K slowed the development of insulin resistance in elderly men in a study of 355 non-diabetic men and women ages 60 to 80 who completed a three-year clinical trial at the Jean Mayer Human Nutrition Research Center on Aging at Tufts University (USDA HNRCA).

Researchers identify molecule that tells your brain your stomach is full

In studies with mice and rats, researchers have found that a chemical messenger called NAPE is made in the small intestine after the animals ate a greasy meal. After eating, NAPE - N-acylphosphatidylethanolamine, a mouthful in itself -- enters the blood and travels to the brain, where it quashes hunger signals.
