Shifting From Carbohydrate to Fat for Exercise

Summary: The following information was written by Atkins professionals. The purpose of this study was to assess metabolic adaptations to a high-fat diet in endurance cyclists. Sixteen endurance-trained cyclists were randomly assigned to one of two diet groups for a period of 15 days. One group remained on their habitual diet (30% of calories from Read More

Dukan Diet, Where Is The Science

Where is the Science? Atkins Nutritionals is aware of no science nor clinical research that supports the claims made for the Dukan Diet.

What is the Metabolic Syndrome and Do You Have It?

It’s estimated that nearly one in four American adults has this dangerous condition but you needn’t be one of them. Also known as syndrome X or insulin resistance syndrome, metabolic syndrome triples the risk of developing heart disease and is a precursor of type 2 diabetes. Along with expanding waistlines, Americans are experiencing an epidemic Read More

Two Studies Shed Light on Weight Loss

Two brand new studies offer some interesting insights on how people lose weight as well as how to overcome the challenge of keeping it off successfully. In the first study, (1) researchers at Bowling Green University wanted to explore the relationship of mood and exercise participation. It’s already been established that exercise enhances mood, but Read More

Could we have been wrong about exercise and weight loss?

In a thought-provoking article in New York Magazine, Gary Taubes reviews the evidence for exercise and weight loss and the relationship turns out to be far more complex than most of us thought. For years, conventional wisdom held that you lose weight by exercising (and, of course, by eating less). These two cornerstones of dietary Read More

Resistance training and dietary protein: effects on glucose tolerance and contents of skeletal muscle insulin signaling proteins in older persons1,2,3

Background:Resistance training (RT) and dietary protein independently influence indexes of whole-body glucose control, though their synergistic effects have not yet been documented. Objective:This study assessed the influence of dietary protein intake on RT-induced changes in systemic glucose tolerance and the contents of skeletal muscle insulin signaling proteins in healthy older persons. Design:Thirty-six older men and Read More

Ketogenic diets and physical performance

Summary: Ketogenic diets and physical performance Impaired physical performance is a common but not obligate result of a low carbohydrate diet. Lessons from traditional Inuit culture indicate that time for adaptation, optimized sodium and potassium nutriture, and constraint of protein to 15–25 % of daily energy expenditure allow unimpaired endurance performance despite nutritional ketosis. Commentary: Read More

Enhanced Endurance in Trained Cyclists During Moderate Intensity Exercise Following 2 Weeks Adaptation to a High Fat Diet

Summary: The following information was written by Atkins professionals. This study sought to compare the effects of two weeks of a high-fat, low-carbohydrate diet (70% fat, 23% protein and 7% carbohydrate) with two weeks of a high-carbohydrate, low-fat diet (74% carbohydrate, 14% protein and 12% fat) on exercise performance. Five trained cyclists were required to Read More

Effect of Protein Intake and Physical Activity on 24-h Pattern and Rate of Macronutrient Utilization

Summary: The following information was written by Atkins professionals. The aim of this study was to evaluate the effect of a high-protein intake compared with a “normal”-protein intake on energy substrate utilization (burning protein, fat or carbohydrate for energy). Fourteen men were placed on a standardized diet and exercise regimen for six days. Then, six Read More
