Fat loss versus muscle loss
It is important to understand the difference between losing weight and losing fat . Weight loss typically involves the loss of fat, water and muscle. A dieter can lose weight without losing too much fat. People who are overweight should try to lose fat and preserve muscle , since muscle burns more calories than fat. Generally, the more muscle mass have higher metabolism so you burn more calories even at rest. Since muscles are denser than fat, muscle loss results in a small physical loss compared to a loss of fat. To determine if weight loss is due to the fat have been developed several methods to measure body fat percentage.Get the facts at https://24timeravis.dk/kostvejlederuddannelse-bliv-kostvejleder-og-diaetist-uddannelse/ website
Muscle loss during weight loss can be restricted lifting weights regularly (or other exercises designed to increase thrust force) and maintaining a sufficient intake of protein . According to the National Academy of Sciences, the necessary protein intake for adults is 0.8 grams per kilo of weight.
Dieters low carb , especially those who do vigorous exercise should increase protein intake. However, this may involve risks. According to the American Heart Association, excessive protein intake can cause liver and kidney problems, and may be a risk factor for heart disease. There is no conclusive evidence that diets moderately high in protein are dangerous to healthy individuals, but they are in people who already have liver or kidney problems.
Energy from food
The energy we get from food is limited by the efficiency of digestion and energy conversion. The efficiency of digestion is largely dependent on the type of food you eat. The little seeds are not digested well-chewed. Refined sugars and fats are absorbed almost completely. Despite the claims of some popular diets, the chewing and digestion do not use a substantial amount of energy offered by any food. Even celery, known for its low calories, contains enough sugars (including sucrose, glucose and galactose) to easily offset the cost of energy invested in chewing . The efficiency of conversion of energy by skeletal muscles is about 20%, ie the chemical energy used, 20% is spent on work and 80% creates heat.
