When you hear metabolism the first thing you might think of is the number of calories your cells burn each day. Metabolism is actually the sum of all chemical reactions that take place in the body. Metabolic reactions that produce energy are dependent on the cardiovascular system‚ which send oxygen to all the cells in your body. Although metabolism is not primarily made of reactions that burn nutrients like carbohydrates‚ fats and protein‚ these are perhaps the most widely known of the metabolic

regular diet for it to be more nutritious. By reviewing my regular eating patterns‚ I realized I eat too many carbohydrates a day. The amount of carbohydrates I consumed was more than double the RDA‚ Recommended Dietary Allowance. To help reduce my carbohydrate consumption‚ I plan on eating less cereal because that has become a go-to meal for me at college. Cereal can add up in sugar and carbohydrates quickly when it is eaten as a meal or in large amounts. I also plan to eliminate the amount of bread I

Edward F. Coyle’s article‚ Fat Metabolism During Exercise: New Concept‚ focuses on answering the question to “what limits the rate at which people can convert their body fat into energy during exercise. He focuses on the different components of fats‚ such as the adipose tissue‚ blood plasma‚ and the oxidization of fats. He highlights how within the adipose tissue there an estimated 50‚000 to 60‚000 kcal energy stored as triglyceride and an obese individual will have more energy than compared to an

Metabolic Rate of a Mouse Lab Write-Up A . The purpose of this experiment was to measure the oxygen consumption of a mouse in which I concluded that they would have less consumption considering their much smaller size. It turned out that they produced 60 O /min which means they use about 0.0024 cal/min or 3.5 cal/day. That is indeed less than the amount we humans use‚ but if the given the mass of a human‚ they would use 15‚ 313 cal/day which is more than the 2‚000 calories we use on an

substitutes; fats; free foods; combination foods; fast foods; and alcohol. Carbohydrate Counting When you eat a healthy meal or snack‚ it is usually a mixture of carbohydrate‚ pro- tein‚ and fat. However‚ your body changes carbohydrate into glucose faster than it changes protein and fat into glucose. It is the carbohydrate that makes your blood glucose level go up. In carbohydrate counting‚ you count foods that are mostly carbohydrate. These include starches (breads‚ cereals‚ pasta)‚ fruits and fruit

Carbohydrates Carbohydrates are the most important nutrient for the body as it is the largest possible source of energy. Carbohydrate supplies the body with energy‚ which allows the brain to function more effectively and allows organs to operate sufficiently. When the body has energy this allows each person to perform a variety of exercise regimes such as high intensity‚ fat burn and continuous training. When the body consumes carbohydrates the digestive system changes carbohydrates to glucose
