People used to believe that the way to lose weight is just to eat less. And sure enough, if you consume less calories than you expend then you’ll lose weight. But whether the weight you lose is muscle or fat depends on how you do it. Just like a certain diet helps you stay lean while you’re gaining muscle, the proper diet will helpyou hold onto your muscle while you’re losing fat. We believe that proper nutrition is the foundation of body-building success. When it comes to fat loss, there are no miracles or shortcuts. It takes a good lean diet and plenty of aerobic exercise. We’ve developed an approach to dieting we call “building your metabolism.” Instead of starving yourself, give your body all the nutrients and calories it needs to be healthy.
Your metabolic rate is your body’s rate of energy expenditure, in calories per hour (1). Your body is constantly consuming energy to maintain itself and fuel activities. When you drastically reduce calories your body thinks it’s starving, so it slows down your metabolic rate to save fuel. You actually lose more muscle than fat during low calorie diets. And since muscular tissue burns more calories per hour than fat tissue, if you lose muscle mass your metabolic rate automatically slows down. Paradoxically, drastically cutting calories actually promotes fat storage by increasing the activity of a fat storage enzyme called lipoprotein lipase (2). When your body’s starving it wants to hold on to all the fat it can, to try and ensure its survival. Your body fat stores represent an energy reserve to keep you alive until the famine passes. So during a low calorie diet you do lose weight, but most of it is muscle and water. And in the process your metabolism slows down and your fat storage systems are cranked up.
So when you resume normal caloric consumption you gain back the weight you lost, if not more. The difference is you lost mostly muscle and you gain back mostly fat, so the net result of your diet is that you’re fatter than when you started. This is why low calorie diets are not effective. So what do you do? How can you achieve an energy deficit without losing muscle and activating your fat storage systems? By feeding your body the right combinations of foods, at the right times, you can shift your metabolism into an anabolic, fat-burning mode. That’s what the Parrillo Performance Nutrition Program is all about. By speeding up your metabolism you can achieve an energy deficit without cutting calories. As you know, different foods have different effects on your body. Foods like cheeseburgers and french fries tend to make you fat. On the other hand, it’s hard to get fat eating rice and fish.
Scientists call this “food efficiency” – the calories consumed of a particular food divided by the resulting weight gain (3). The higher the food efficiency, the more that food contributes to weight gain. Foods with a low food efficiency are more prone to be burned for energy instead of being converted to bodyweight. CapTri® is a special kind of fat called a medium chain triglyceride. CapTri® harnesses the energy density of fat but is not stored as bodyfat (4). The molecular structure of CapTri® results in it being metabolized differently than conventional fats. Instead of being transported to fat depots like regular fats, CapTri® is transported directly to the liver and is immediately burned to produce energy (4, 5). As a result, CapTri® has a lower food efficiency than regular fats (3, 5). When conventional dietary fats are replaced with lipids like CapTri®,test animals stay much leaner (6,7). Probably the most amazing thing is that lipids like CapTri® also have a lower food efficiency than carbohydrates (3, 8). This means that it’s harder for your body to convert CapTri® into fat than it is to store excess carbohydrates as fat. Bodybuilders use CapTri® while dieting because it has a lower food efficiency than carbohydrates and conventional fats (3, 6, 7, 8).CapTri® is burned rapidly in the liver (4, 5) and some of the energy is released as body heat in a process known as thermogenesis. Thethermogenic effect is probably the most important reason why CapTri® has such a low food efficiency (5, 7, 9, 10). Instead of being stored as fat, excess calories from CapTri® are converted to body heat, and this means you burn more calories per hour. This explains why calories from CapTri®contribute less to fat stores than an equivalent number of calories from conventional fats or carbohydrates(3, 6, 7, 8).
Scientific studies have shown that when lipids like CapTri® are used in place of carbohydrates,body fat stores are lower (3, 8). And less carbohydrates are converted into fat, even in the presence of insulin (8). Insulin is an anabolic hormone which is released from the pancreas in response to an increase in blood glucose (sugar). Insulin causes cells to absorb glucose and amino acids, thereby stimulating growth. Unfortunately, insulin also causes fat cells to absorb glucose and fatty acids, stimulating fat storage. Fat storage enzymes are less active when lipids like CapTri® are added to the diet, even under conditions of insulin stimulation (8). Bodybuilders have used low-carb diets for years. When you reduce carbs you in turn reduce insulin(remember, insulin promotes fat storage) and activate the carnitine shuttle. The carnitine shuttle is a transport system which moves fatty acids inside mitochondria – the furnaces inside cells where foods are burned for energy.
Carbohydrate metabolism generates a by-product called malonyl-CoA, which inhibits the carnitine shuttle. This is why not much body fat is burned for energy as long as carbohydrate fuel is available. During low carb diets no malonyl-CoA is produced so the carnitine shuttle is activated.The body shifts into a fat-burning mode. Glucagon is another hormone, also produced by the pancreas, but with the opposite actions of insulin. After you eat a big carbohydrate meal your body releases insulin which causes cells to absorb glucose. Some of the glucose is used for energy and the excess is stored as glycogen and fat. As the blood glucose level goes down, the insulin level goes down too. After your cells run out of glucose, glucagon is released as a signal to begin burning fat. The problem with the old low-carb diets is that you don’t have much energy and your metabolism slows down because you’re not consuming enough calories.You’re really not consuming any fuels that your body likes to use for energy. In the new low-carb strategy, you use CapTri® in place of starchy carbs. This results in decreased insulin production and in-creased glucagon release. The carnitine shuttle is active and fat metabolism proceeds at a maximal rate. The calories from CapTri®provide the energy you need to keep training hard. Also, by substituting CapTri® for an equivalent number of calories from carbohydrates you avoid the slow-down in metabolic rate which inevitably results from calorie-restricted diets.
Since CapTri® has a lower food efficiency than carbohydrates, this means your calories will be burned instead of being stored as fat. CapTri® is the most highly refined, ultra purified MCT on the market. The formulation of CapTri® was specifically designed for people who want to be as lean as possible. CapTri® is available exclusively from Parrillo Performance. So if you’re looking for a good source of calories to provide energy while dieting, try CapTri®. And do your aerobics.
