1. 32 year old male, 5'8" tall, medium built performing moderate activity.
2. 28 year old female, 5'2" tall, medium built performing light activity.

Answer 1

  (a) DBW ( desirable body weight )  

we can calculate our ideal body weight by - Tannhauser formula is -

• subtract our height in centimeters by 100 . the answer in kg will be our body weight . If our height is 178  cm then our ideal body weight should be 78kg.
• For small frame , the calculation is ( height-100 ) - {10% of (height-100) } in kg
• for medium frame , ( height -100 ) kg is the ideal weight .
• For large frame , the calculation is ( height - 100) + {10% of ( height -100 ) } in kg.

DBW (kg) = [ Ht (cm) - 100 ] +/- 10%

(b) Basal Metabolic Rate , (BMR) is often used interchangeable with resting metabolic rate (RMR) . while BMR is a minimum number of calories required for basic functions at rest , RMR ---- also called resting energy expenditiure (REE) ---- is the number of calories that our body burns while it's at rest .

Our popular method to calculate BMR is through the Harris - Benedict formula , which takes into account weight, height , age and the gender,

Women ;-

BMR = 655+ (9.6 x   weight in kg ) + (1.8 x   height in cm ) - (4.7 x  age in years)

Mem;-

BMR = 66 + ( 13.7 x  weight inkg ) + ( 5 x height in cm ) - (6.8 x age in years)

(c)

The physical activity level is a way to express a person daily physical activity as a number and is used to estimate a person 's toatl energy expenditure , it is the combination with the basal metabollic rate , it can be used to compute the amount of food energy a person needs to consume in order to maintainm a particular lifestlye

It is calcuted by the formula, that the total energy expenditure (TEE) in a 24 hour period , divided by his or her basal metabolic rate (BMR) .

Physical activity level = TEE(24hrs) / BMR

(d) Specific dynamic action (SDA) is also known as Thermic effect of food (TEF) or the dietary induced thermogenesis (DIT) , it is the amount of energy expenditure above the basal metabolic rate due to the cost of processing food for use and storage ,

THE phenomenon of the extra heat production by the body , over and above the calculated caloric value , when a given food is metabolized by the body is known as specific dyanamic action ( SDA)

SDA of food is due to the energy required for digestion , absorption, transport , metabolis and storage of foods in the body ,

The SDA of protein is primarily to meet the energy requirements for deamination , synthesis of urea , biosynthesis of protein ,, synthesis of tricylglycerol ( from carbon skeleton of amino acids ) .

Phenylalanine , glycine and alanine increse the SDA

The SDA of carbohydrates is attributed to the energy expenditure for the conversion of glucose to glycogen ,

fat , the SDA be due to its storage mobilization and oxidation .

Consumption of protein rich diet cold climates

IN a cold climates , diet rich in protein is recommended , it helps to maintain the body temperature,

DUe to its high SDA , liberates extra heat .

(e) Total energy requriment also know as energy expenditure , it is the amount of energy that a person needs to carry out physical functions such as breathing , circulating blood , digested food or excersicing .

Energy is measured in calories and our total daily energy expenditure (TDEE) is the number of calories our burn in each day .

To prevent weight gain , energy intake must be balanced with energy expenditure .

Total energy expenditure or calories expended = RMR ( resting metabolic rate ) + TEF ( thermic effect of food ) + PA 9physical activity )

(f) The Calories is refers to everything we eat or drink that has calories in it . 'Calories out ' isv everything we do that uses energy , from simply being alive ( heart beating , lung breathing , and digestion ) to walking , talking and the working out proccess . The realationship between the input and output of calories dictates whether we gain , lose or maintaining weight .

calories in > Calories out = calorie surplus & weight gain

Calories Out - calories In = balance & weight maintaining

Calories in < Calories out = calorie deficit & weight loss

Fat loss = our body weight in lbs x 12

maintenance = our body weight in lbs x 14

muscle building = our body weight in lbs x 16
