The Glycemic Index (GI)
The Glycemic Index (GI) ranges from 0 to 100+ and refers to the rate at which a carbohydrate enters the bloodstream and causes an insulin response. It compares carbohydrates gram for gram in specific foods by providing a numerical index of glucose in the blood after a meal.
So, If you’re looking to maintain muscle and reduce body fat then it is important to select meals with a low glycemic rating. Read the article below for additional information.

The Glycemic Index - Key to Fat Loss
or Just Another Diet Gimmick?
The glycemic index (GI) is a scale that measures how quickly carbohydrate foods are broken down into glucose. The original purpose for the glycemic index was to help diabetics keep their blood sugar under control. It has recently attracted a lot of attention in the bodybuilding, fitness and weight loss world and has even become the central theme in numerous best-selling diet books as a method to choose the foods that are best for losing body fat.
According to advocates of the glycemic index system, foods that are high on the GI scale such as rice cakes, carrots, potatoes, or grape juice are "unfavorable" and should be avoided because they are absorbed quickly, raise blood sugar rapidly and are therefore more likely to convert to fat or cause health problems.
Instead, we are urged to consume carbohydrates that are low on the GI scale as black eye peas, old fashioned oatmeal, peanuts, apples and beans because they do not raise blood sugar as rapidly.
While the GI does have some useful applications, such as the use of high GI foods or drinks for post workout nutrition and the strong emphasis on low GI foods for those with blood sugar regulation problems, there are flaws in strictly using the glycemic index as your only criteria to choose carbs on a fat loss program.
For example, the glycemic index is based on eating carbohydrates by themselves in a fasted state. If you are following effective principles of fat-burning and muscle building nutrition such as those outlined in my Burn The Fat, Feed The Muscle (BFFM) e-book www.BurnTheFat.com, you should be eating small, frequent meals to increase your energy, maintain lean body mass and optimize metabolism for fat loss.
However, since the glycemic index of various foods was developed based on eating each food in the fasted state, the GI loses some of its significance.
Myo Lean - Advanced Meal Replacement
Myo Lean is an advanced low glycemic meal replacement especially formulated to produce slow releasing carbohydrates that keep fat storage to a minimum by stabilizing insulin levels while also providing long lasting energy.
· Low GI (slow releasing carbs)
· Build Lean Muscle
· Lose Unwanted Body Fat
· Complete With Vitamins & Minerals, BCAAs & Glutamine
Because of its carbohydrate source, Myo Lean is extremely low on the GI. Most other meal replacements contain maltodextrin as a primary carbohydrate source. Maltodextrin has a Glycemic Rating of 100+. That is higher than pure sucrose!
So, Myo Lean helps take the guesswork out of your nutritional game plan by providing the highest quality protein sources, low glycemic carbohydrates, vitamins and minerals, added BCAA's, glutamine peptides, and essential fatty acids all packed into one delicious and convenient shake. Myo Lean will help assist in your training goals of becoming leaner, stronger, and healthier.
By the way, Myo Lean is guaranteed to be the best tasting protein shake on earth. You'll never have to gulp down another protein shake again for the sake of nutrition. This is a shake you will look forward to drinking.

In addition, when you are on diet programs aimed at improving body composition, (losing fat / gaining muscle), you will usually be combining carbs and protein together with each meal for the purposes of improving your fat to muscle ratio. When carbs are eaten in mixed meals that contain protein and some fat, the glycemic index loses more of its significance because the protein and fat slows the absorption of the carbohydrates (so does fiber).
Mashed potatoes have a glycemic index near that of pure glucose, but combine the potatoes with a chicken breast and broccoli and the GI of the entire meal is lower than the potatoes by itself.
Rice cakes have a very high glycemic index, but if you were to put a couple tablespoons of peanut butter on them, the fat would slow the absorption of the carbs, thereby lowering the GI of the combination.
A far more important and relevant criteria for selecting carbs - and ALL your foods, proteins and fats included - is whether they are natural or processed. To say that a healthy person with no metabolic diseases or disorders should completely avoid natural, unprocessed foods like carrots or potatoes simply because they are high on the glycemic index is ridiculous.
I know many bodybuilders (including myself) who eat high glycemic index foods such as white potatoes every day right up until the day of a competition and they reach single digit body fat. How do they do it if high GI foods make you fat? It s simple high GI foods DON'T necessarily make you fat choosing natural foods and burning more calories than you consume are far more important factors. Although it s not correct to say that all calories are created equal, a calorie deficit is the most important factor of all when fat loss is your goal.
The glycemic index need not be completely disregarded, as it is a legitimate tool in certain situations, but diet programs that hang their hats on GI alone are just another example of how one single aspect of nutrition can be used as a "hook" in marketing and said to be the "end all be all" of fat loss, when it's really only one small piece of the puzzle.
Eating Low glycemic index foods alone does NOT guarantee you will lose fat. You have to take in the bigger picture, which includes calories/energy balance, meal timing and frequency, macronutrient composition, food choices as well as how these nutritional factors interact with your exercise program.
