Karen is interested in speeding up her basal metabolic rate to promote fat loss; you would advise her to:

Select one:

a. Fast at least one day each week

b. Participate in endurance and strength-building exercise daily

c. Start smoking

d. Follow a low carbohydrate diet

Answer 1

4 )

a) storage of energy

• Proteins are large macromolecule , which consist of small amino acid which are linked together by peptide bond.
• Main storage form of energy in the body is carbobhydrate .The body uses , energy from carbohydrate if there is immediate requirement .
• Energy from protein is taken , if there is a long starvation.
• The primary function of protein include building of muscle and bone , synthesis of hormones , enzymes and antibodies. Hence option B , C and D are incorrect.

10)

b) It supports basic body processes

• BMR ( Basal metabolic rate) is the amount of energy used by a person at rest.
• BMR is required for normal activities of body performed by organ like kidney , heart , muscle etc
• There are many factors affecting BMR , which include muscle mass , age , body size , gender , diet etc
• Option A is incorrect because thyroid hormone control basic metabolic rate .
• Option C is incorrect because BMR doesnot affect fever.
• Option D is incorrect because BMR affects the lean muscle tissue .More amount energy is required , if there is large muscle mass .

11)

b) 157

• After digestion 1 gram of carbohydrate gives 4 calorie of energy , 1 gram of protein give 4 calorie of enrgy and 1 gram of fat gives 9 calorie of energy.

Given ,

• 20g of carbohydrate = 20 x 4

   = 80 calories

• 8 g of protein = 8 x 4

= 32 calories

• 5g of fat = 5 x 9

= 45 calories .

• Total Calories = 80 + 32+ 45

= 157 calories

• All other options are wrong because of incorrect value

15)

b) Partcipate in endurance and strength-building excercise daily.

• One of the important factors affecting BMR include physical activity . By performing strength traaining excercise daily cause speed up of BMR and increase fat loss.
• High intensity excercise cause burning of calories very quickly and increases amount of muscle.
• Option A is wrong because fasting atleast one day doesnot cause speed up BMR , because more amount of food will be taken remaining day of the week , and no change in total calorie count.
• Option D is wrong because , high protein diet cause fat loss , low carboydrate doesnot speed up basal metabolic rate.
• Option C is wrong because smoking doesnot cause fat loss and it is injurious to health.
