Here's what I've found out about how to 'rev up' the metabolic rate.
Insulin; it's job is to feed cells with proteins and sugars to build body parts and energize movements. Proteins and sugars come from the food we eat. Insulin travels to all the organs, muscles and the fat cells, trying to make sure everyone is fed. This in turn makes the metabolism rise as the natural sugars build glycogen. Building glycogen causes our cells to release calories in the form of heat. There's a name for that, TEF (thermic effect of food).
Boosting the metabolism depends on the right foods to spark a burn. The best glycogen burner is made from natural sugars that come from complex carbohydrates. So spaghetti, beans and most vegetables are good carbohydrates for that. The best foods being those that contain both carbs and protein, such as broccoli and some other vegetables that are aobut 50% complex carbs and 40% protein.
Most fats, like those in french fries and fried chicken are mainly stored as...well...fat in the body. Excess fats prohibit the insulin in the body from doing its job thoroughly much like a person trying to win a race by running through an oil slick. It can be done, but not effectively or properly. This is insulin resistance. What happens then is, the pancreas tries to compensate by sending out even more insulin to help get the proper nutrients into the cells. When you get that 'extra' insulin in the blood stream, you temporarily shut down the fat-burning machinery. Is simply stops the release of fat from the body fat stores and keeps it for anther time when food is short in supply.
A persistent insulin rise actually increases the fat storing enzymes in the fat tissues so that the body can actually store fat more easily and makes it less available to the muscles to burn.
If you're tracking your food and you are on a standard western diet, you'll find its hard to keep your fat ratio down. Why? Because fat is in just about everything, and cheese is almost all fat! Even low-fat cheese and reduced-fat cheeses have about 6 grams of fat, with 4 grams of saturated fat. per ounce, even some vegetables and fruits as well as grains and beans; and protein is found in many vegetables, beans, rice, pasta and even some fruit, it's not just in animal products as some people think;
The point here is, we want to be sure to eat enough carbohydrates with proteins to help our bodies burn the fat reserves we already have and not store more fat.
