Question

An analysis of a patient diet shows that they are 90-gram carbohydrate, 10-gram protein and 10 grams fat each day. Approximately how many calories did this patient consume in one day?

Answer 1

How much energy food provides to the body is measured by a unit of energy known as a calorie. To function properly our body needs calories. In food or drink items the amount of energy is measured in the form of calories.

Complete answer:
90% of the dry weight of the diet and 100% of energy are supplied by carbohydrate proteins and fats. All these provided energies measured in the calories. They all are very much different depending on how quickly they supply energy.
-Carbohydrates provide energy very fast whereas fats provide energy very slow.
-The carbohydrates, proteins, and fats are broken down into the basic unit by the intestine. The basic units are -
-Carbohydrates into sugars
-Proteins into amino acids
-Fats into fatty acids and glycerol
to build the substance needed for the growth, maintenance, and activity these basic units are used by the body.
-Diet of energy in 1 gram of a basic human diet are -
-4 calories in a gram of carbohydrate or proteins
-9 calories in a gram of fat
Therefore,
1)The 4 calories per gram present in the carbohydrate which means calories present in 90 grams of carbohydrate = 4×90 = 360 calories.
2)The 4 calories per gram present in the proteins which means calories present in 10 grams of proteins = 4×10 = 40 calories.
3)The 9 calories per gram present in the fat which means calories present in 10 grams of fats = 9×10 = 90 calories.

So, in the present patient diet total calories present are = 360 + 40 + 90 = 490 calories.
-From the carbohydrates proteins and fats calories comes in the food. 4 calories present in 1 gram of carbohydrate, 4 calories also present in 1 gram of protein, and 9 calories present in 1 gram of fat which is twice the amount of the other two.
-Therefore calories do not depend upon one food with the same serving size. more calories are present in high-fat food as compared to food that is low in fat. Calories are higher in proteins or carbohydrates.

Note:
-The amount of force significantly impacts on body functions that we consume daily.
-Calories are burnt by the body for a living. This is known as the basal metabolic rate which maintains the heartbeat, digestion of food, creating new tissue cells.
