Glycemic Index and Fat Loss
Muscular Development|January 2022
For many years we were told the keys to losing weight and staying healthy are to exercise and eat a low-fat/high-carbohydrate diet. The public evidently heeded this advice as epidemiological studies have shown that dietary practices of Americans have shifted accordingly. Yet, despite this shift, the incidence of obesity and diabetes in America has reached epidemic proportions, particularly in children and adolescents. This phenomenon has been explained as a result of an increasingly sedentary lifestyle and consumption of nutrient-dense food.

Glycemic Index and Fat Loss

While these factors have certainly contributed to these problems, studies investigating the efficacy of low-fat/high-carbohydrate diets compared to other dietary approaches have not been too impressive. The findings have led a number of obesity researchers to conclude that there may be more to fat loss than simply reducing fat intake by replacing it with carbohydrates. This discussion addresses how the glycemic index (GI) of carbohydrates affects insulin, fat metabolism, appetite, obesity and weight loss.

WHAT IS GLYCEMIC INDEX?

Dietary carbohydrates are converted to glucose and released into the bloodstream. As a result, insulin is released from the pancreas to facilitate storage of the glucose in the liver and muscle. The faster carbohydrates are digested, the more rapidly glucose and insulin levels increase in the blood. The magnitude that a specific carbohydrate increases blood glucose and insulin can be quantified by measuring the glycemic index (GI).

Best Cardio for Fat Loss - High Intensity vs. Low Intensity

Low-intensity cardiovascular exercise is the most common way to reduce body fat, despite mounting scientific evidence showing this form of cardiovascular training may not burn body fat as effectively as high-intensity cardio. In addition, low-intensity cardio has also been shown to inhibit muscle growth¹2, making the use of this approach to enhance your physique even more questionable.

BRYAN JONES: THE LORD OF CLASSIC RETURNS!

It seems like a decade has passed since the pandemic began in 2020. That was a chaotic year for all of us. MD sent me to Atlanta to cover the Chicago Pro, because restrictions in Illinois made it impossible to hold Tim Gardner's annual extravaganza there. The athletes still showed up in force to compete, and the Classic Physique division alone featured 30 men. When they came out to be adjudicated, one man stood out in a flash as the one to beat. I had never heard of Bryan Jones until that point aside from a vague recollection that he'd won the USA a couple of years before. With his braided and colored hair piled on top of his head in a gathered bun with the ends appearing to be some type of bizarre plant, I dubbed him \"The Kai Greene of Classic.\" That didn't stick, thankfully, because Bryan \"Lord\" Jones is a unique athlete in his own right. I knew I was looking at a man who was going to make waves in that division. A few months later he did just that, placing fifth in his first Olympia appearance. But we only saw him twice more after that, at the Arnold Classic and once again at the Olympia at the end of 2021. Since then, Jones has been working hard to build the additional size needed to successfully transition to the Open category. I spoke with him about his brief but notable time in Classic, and how he plans to make a big splash in Open.

HOW MUCH REST IS BEST?

Getting enough rest after weight training is essential for optimal muscle growth and performance. Unfortunately, many get insufficient rest because they simply disregard the fact that weightlifting breaks down muscle tissue, creating the requirement for adequate rest to fully recuperate.

Get Peeled With Extra Virgin Olive Oil

As you know, pathologic fat accretion results in obesity. The medical community and pharmaceutical industry have been struggling to address this burgeoning condition in the Western culture - particularly in the United States. Obviously, individuals have also been struggling in their attempts to avoid or correct unsightly or unhealthy fat gain. Imagine the shame these professionals and people must feel when they realize they may have been ignoring a risk-free, health-promoting, inexpensive dietary ingredient that can enhance fat loss. Bodybuilders seek potent drugs or supplements to force the metabolism to strip body fat to low single-digit percentages, but failing to acknowledge the foundation of diet can sabotage even their extreme measures.

CREATINE: THE BEST FORMS

New products and formulations are introduced to the supplement market every day. However, it is very rare for a product or especially an ingredient to create noteworthy evolution in supplement performance. Arguably, the greatest leap up this axiomatic evolutionary ladder occurred with the advent of creatine supplements in the 1990s. Creatine has proven over and over to be \"the real deal\" in clinical research and broscience. It's a muscle-building, performance-enhancing supplement that nearly all athletes should use.
