Keys to losing FAT without losing MUSCLE

A study performed at the University of Connecticut showed that exercisers who switched from a balanced diet (proteins, carbohydrates and fats) to a low carb diet experience the following drop's in athletic performance. There was a 7 - 9 percent drop in muscle power and 6 percent drop in VO2 max of cardiovascular performance. Another factor to consider is the recuperation of muscle between workouts is decreased on low carb diets. So why would someone go on a low carb diet, especially when exercising? Because the initial weight loss that comes from the glycogen depletion is believed to be fat loss.
We have become so focused on weight loss, that any weight loss is seen as good. As identified earlier in this article glycogen is a mixture of glucose and water and the majority are stored where? You guessed it, the muscle. A large percentage of the initial weight loss is coming from muscle loss. I don't think any exerciser desires to have smaller muscles as a result of their exercising. The goal of exercise should be to improve body composition, the percentage or ratio of muscle to body fat. This can only be accomplished by losing fat without the loss of muscle tissue. Maintaining muscle mass is vital to sustainable weight control. The following steps will protect your muscles as you are losing fat, while reaching your ideal weight and ideal body composition.
1. Cycle fat burning days with recovery days.
The secret to losing fat without losing muscle starts with not being too aggressive or extreme with your reduction of carbohydrates. You need carbohydrate management, not carbohydrate elimination. Over the last 20 years, with more than 10,000 clients I've found by reducing carbohydrates by 20% of daily needs and within 48 hours replenishing the glycogen in the muscle by eating 100% of daily carbohydrate requirements, allows for fat loss, without muscle loss. In essence you have two fat burning days, then a recovery day. By doing this you'll have the best of both worlds. You will experience fat loss that averages between 1-2 pounds weekly, while muscles are being well fed. You never drastically deplete the glycogen stores in the muscle so athletic performance is not affected like on a low carb diet.
2. Exercise on days where you are receiving more carbohydrates.
Exercising on days where muscle are getting more carbohydrates for fuel and taking days off from exercise when you are being aggressive about fat loss. One of the most difficult thoughts for exercisers to accept is that most of the results from exercise come when we are not exercising. They come after we exercise and in direct response to how the muscles receive nutrition after exercise.
3. Exercise 1.5 - 2 hours after eating when blood sugar levels and insulin levels are slowly declining.
As insulin levels increase in response to a rise in blood sugar after a meal, the cells are in an anabolic state (receiving nutrients). Insulin is the hormone that feeds are cells. As blood sugar levels drop, insulin levels drop and the pancreas produces the hormone glucagon and nutrients stored in the fat cells are released to the blood and used for energy. The management of this blood sugar rise and drop is important. If blood sugar levels go to high insulin feeds the muscle cells and deposits excess into fat cells. If insulin levels go too low, the muscle cells are being under fed. A slow rise in blood sugar provides good nutrition to the muscles and a slow drop allows glucagon to take from the fat cells. Timing your exercise to this blood sugar decline allows the muscles to receive from the fat cells more effectively. It is important to never exercise without having at least one meal left in your day so that muscles can recuperate from exercise.

Exercise & Low Carb Diets Don't Mix

Over the last twenty five years the most common questioned asked me by frustrated exercisers, has been what exercise routine will get me the body I desire? My answer is always the same. They need to start exercising better judgment and learn that exercise alone will not solve their body composition problem.

I believe the number one reason for starting an exercise program is weight reduction, even before fitness and health concerns. Exercise by itself is a poor weight manager and it increases the need for better nutritional requirements. I believe I would receive very little disagreement that a combination of nutrition and exercise is the answer to improvement in weight loss (fat loss), fitness and health risk concerns. With obesity reaching epidemic rates and the dropout rate of most health clubs remaining high this article intent is to lay the foundation why exercise and low carbohydrate diets are poor partners.
Over the last three decades I have seen extreme changes in the macro nutrients (proteins, carbohydrates and fats) combinations in our quests for the ideal body. Everything from high carbohydrate, low fat, high protein, to the current low carbohydrate craze has bombarded us, though the failure rates in managing our weight continue to rise. The problem lies in our bodies ability to adapt to change, especially extreme change. If your goal is to lose fat you must provide your muscle enough quality fuel without being over fueled. This is especially true if your goal to lose fat includes exercise. The secret is not found in elimination of macro nutrients, but in management of them. Understanding how to fuel your muscles prior to exercise sessions and replacing fuel after workouts is critical or your body will break down muscle for fuel.
Understanding how our muscles use the calories we eat as fuel for muscle contraction is the first step in knowing what to do and not to do. A basic nutritional knowledge tells us that proteins repair and rebuild cells, carbohydrates energize cells and fats provide hormonal foundation for cells. When we lack balance in protein, carbohydrates and fats are bodies adjust and can use all three as a source of fuel for muscle contraction and cellular energy. Though energy is needed for all cellular function, the focus of this article is muscle contraction and body composition. All muscle contraction derives energy from adenosine triphosphate or ATP. The primary source of ATP comes from glucose, which is stored in the muscles and liver as glycogen (glucose and water). Muscle contraction during anaerobic activity ( resistance training ) can use glycogen directly to form ATP. The process is anaerobic glycolysis, meaning it can use the glucose as energy with very little oxygen (90% glucose, 5% oxygen and 5% fatty acid). Our muscles only store enough ATP for short periods of muscle contraction, when depleted this leads to muscle failure. The rest period between weight training sets allows additional ATP to be produced. During early stages of aerobic exercise, ATP is again created primarily from glucose until the heart and lungs provide enough oxygen to the muscles to allow fatty acids to be used to create ATP. So there you have it during resistance training and the beginning stages aerobic training the primary source of fuel is glucose.
This supports my claim that low carb diets and exercise make poor partners. To uncover why, we need to quickly look at the concept behind low carb diets and how they work. Any diet that provides 100 grams or less of carbohydrate daily. This article classifies as low carb diet's. This will quickly deplete the glycogen stores in the muscle and liver. This by itself is testimony that our muscle's primary source of fuel is glucose. Fatty acids stored in the adipose tissue (fat cells) are now released into the blood and processed by the liver and some are turned into glucose (gluconegenesis) and some remain fatty acids and both provide ATP for muscle contraction. One of the byproducts of this process is ketone bodies which can provide energy to brain and nervous system. The problem gluconegenesis (non glucose turned into glucose) provides fuel to the muscle less efficiently than glycogenesis (glucose). The end result is increased muscle fatigue, decreased muscle power, which leads to poor athletic performance.

7 Reasons Why Low Carb Diets Can Be Harmful

Obesity is reaching epidemic levels in America and is now the second leading cause of preventable deaths. The medical community used to see it as simply the result of poor eating habits or a lack of will power; now they are beginning to define obesity as a disease that poses a dire threat to our public health. Low carbohydrate diet's have become popular as the solution in our battle to lose weight. Unfortunately the human body is equipped to use carbohydrate as its' primary source of fuel. Sadly the latest low-carbohydrate fad diets are not the fuel the human body was designed to run on. Low - carbohydrate diets can cause several health concerns over time.
Here are the top seven:
Gout
Gout is a form of arthritis that occurs when excessive uric acid levels, start to crystallize in joints, leading to pain and inflammation. Uric acid is a waste product in the liver's metabolism of protein. Excessive amounts of protein may lead to an inability of elimination of uric acid.  The FAT LOSS COACH recommends you should not to exceed 1-1.25 grams of protein per lean pound of body weight.

Kidney Stones
Kidney stones are hard masses that form in the kidneys when uric acid or calcium oxalate crystallizes and over time form stones. Insoluble fiber found only in carbohydrates reduces the absorption of calcium, which cause urinary calcium levels to drop resulting in prevention of kidney stone's formation.  The FAT LOSS COACH recommends the consumption of 30 or more grams of fiber daily. This is not attainable on low carb diets.

Constipation and Poor Intestinal Health
To maintain good intestinal health our bodies require thirty or more grams of fiber daily. Fiber is divided into two types soluble and insoluble. Insoluble fiber is vital in formation of stools and decreases the time process of waste elimination. Low carbohydrate diets are too low in insoluble fiber and increase risk of constipation. Poor transit time of waste material increases risk of certain colon cancers. Insoluble fibers prevent the buildup of mucus on intestinal walls which lead to poor absorption of nutrients into the body. Low carbohydrate diets are inadequate to maintain good intestinal wall health. The FAT LOSS COACH program uses whole grains, oats, beans, fruits and vegetable which are rich in soluble and insoluble fiber. This lowers the risk for constipation, irritable bowel, diverticulitis, Crohn's disease, hemorrhoids and colon cancers.

Risk of heart disease increases on a low carbohydrate, low fiber diets. These diets promote excessive amounts of animal protein, cholesterol and saturated fat. Exuberant amounts of protein increase homocysteine, which is a bi-product of the amino acid methionine. Many experts believe that high homocysteine levels have many toxic effects which lead to increase risk of heart disease and hardening of arteries. Low carbohydrate, low fiber diets reduce the absorption and elimination of digestive bile in the intestines. Digestive bile is produced in the liver from cholesterol. A decrease in digestive bile production raises blood serum cholesterol levels which increases risk of heart disease. The FAT LOSS COACH recommends a nutritional balance. Unlike low carbohydrate diets the FAT LOSS COACH promotes nutritional balance providing 30% protein, 50% high fiber carbohydrates, 20% fat.

Osteoporosis
Osteoporosis is the reduction of bone density, due to the loss of calcium over long periods of time. Several dietary factors increase the risk of osteoporosis. When dietary protein reaches excessive levels, so does the loss of calcium in the urine. Most studies show that a life - long high protein diet results in an increase of osteoporosis. Poor intestinal health due to low fiber diets cause inadequate absorption of calcium in intestines contributing to poor bone formation. This would suggest that all low carbohydrate diets cannot become a lifelong lifestyle of eating. This is only one of many reasons why low carbohydrate diets provide poor Long Term Weight Control. Interestingly, a diet too low in protein can also increase risk of osteoporosis. There is no one size fits all when managing our weight.  The FAT LOSS COACH recommends a balanced nutritional program. All FAT LOSS COACH programs are customized to the individual providing the right balance of protein, carbohydrate and fat.

Loss of Muscle and Reduced Metabolism
Any diet that applies the restriction of calories less than the body's daily requirements over long periods of time will result in the loss of lean muscle tissue and a decrease in the metabolism. All low carbohydrate diets are focused solely on weight loss. The loss of fat comes at a high cost, which is the loss of lean muscle. The loss of muscle reduces the resting metabolic rate, which is the major cause for rebound weight gain. Research shows 95% of all dieters' will regain that weight back.  The FAT LOSS COACH Program is nutritional breakthrough. because of its three day eating cycle, called the GLYCO - CYCLE. The secret is we don't try to lose fat every day. That would result in losing muscle and reducing metabolism

Carbohydrates are the primary fuel for your muscles and brain. Eating a low carbohydrate diet prevent proper maintenance of muscle and liver glycogen ( storage form of carbohydrate and water ), decreasing muscle performance and increasing muscle fatigue. ATP is the main source of energy for all muscle contraction. When a muscle is used, a chemical reaction breaks down ATP to produce energy. There is only enough ATP stored in the muscle for a few contractions. More ATP is needed. There are three enzyme systems that can create more ATP. The three sources of ATP for muscle contraction are carbohydrates, fatty acids and amino acid proteins. Carbohydrates metabolize efficiently and are therefore used first. If carbohydrates are not available, your muscles metabolize fatty acids and amino acids as secondary sources of ATP. These secondary sources are not efficient, which consequently cause your strength and endurance to drop drastically.  The FAT LOSS COACH is customized to your amount of muscle and exercise schedule. It provides 50% of your calories from high fiber, low glycemic ( turn into blood sugar slowly ) carbohydrates which are metabolized into muscle energy best. This will lead to increases in strength and muscle endurance.
