For who says that “A calorie is a calorie” in this perspective mean to suggest that macronutrient proportions are extraneous to weight management. All that substances are the total number of calories consumed, in spite of whether the plurality comes from fat or carbohydrate.
It sounds reasonable, but it’s actually it’s wrong. A calorie is not a calorie, in more than one sense. Carbohydrate, fat and protein calories are indeed equal by label in terms of their energy content, but the body processes each in a distinct way, and these differences have real propositions for weight management. In connection, food calories of all categories may have very different effects on the body depending on when they are eaten and what they are eaten with. Below are the five particular reasons why all calories are not equal.
1. The energy cost to metabolize fat, carbohydrates and protein are not the same
The body must consume energy to digest, take in and metabolize the energy in food. It so happens that the body consumes dissimilar quantities of energy to process different energy-containing nutrients. In general, additional energy is required to process protein than carbohydrates, and additional energy is required to process carbohydrates than fat.
2. Calorie constraint slows metabolism
The major problem with using linear calorie equations for fat loss is that the lesser calories you intake, the lesser calories your body burns. Therefore, if, based on the 3,500-calorie rule mentioned above, you make a decision to cut your daily energy consumed by 500 calories in hopes of losing a pound a week (500 calories/day x 7 days = 3,500 calories), you will most likely find that you do certainly lose a pound in the first week but fewer in each following week. This incident is believed to represent a metabolic adaptation to prevent malnourishment. Your body exactly runs cooler to conserve the reduced number of calories you’re eating, thus effectively increasing the value of each calorie.
3. Protein decreases appetite
Protein in general decreases appetite more per calorie than fat and carbohydrate. Thus ,a person who increases his daily protein consumed without making any conscious attempt to eat less is likely to eat less in any case due to reduced appetite. This is one more important sense in which protein, carbohydrate and fat calories are not equal.
4. Fiber decreases calorie amalgamation
Fiber is a form of carbohydrate that contributes to satiety without contributing calories, because it is not being absorbed into the body. as a result, a 100-calorie high-fiber food will decreases appetite and succeeding eating more than a 100-calorie low-fiber food. Similarly, a person who increases his daily fiber consumption without making any conscious effort to eat less will wind up eating less anyway due to reduced appetite. Thus, a calorie inside a high-fiber food is not equal to a calorie inside a low-calorie food-yet a fourth way in which “a calorie is not a calorie.”
