Question

Sunil weighs 150 pounds and would like to lose a little weight by replacing his sugary beverages with water or black tea and adding brisk walking to his normally sedentary life. If these measures decreased his former calorie intake by 250 calories a day and increased his energy expenditure by 250 calories a day, how long would it take Sunil to lose about one pound?

Answer 1

Sunil would take approximately 7 days to lose about one pound by replacing sugary beverages with water or black tea and adding brisk walking to his sedentary life.

Step-by-step explanation:

To calculate how long it would take Sunil to lose about one pound, we need to understand that one pound of weight loss is equivalent to 3,500 calories. Sunil's measures of replacing sugary beverages with water or black tea and adding brisk walking decrease his calorie intake by 250 calories a day and increase his energy expenditure by 250 calories a day. So, the total calorie deficit per day is 500 calories (250 calories decrease in intake + 250 calories increase in energy expenditure).

To determine how long it would take to lose one pound, we divide the total calorie deficit of 500 calories per day into the total calorie deficit needed to lose one pound, which is 3,500 calories. This can be calculated as follows:

Time = Total calorie deficit needed / Total calorie deficit per day

Time = 3,500 calories / 500 calories per day

Time = 7 days

Thus, it would take Sunil approximately 7 days to lose about one pound by implementing these measures.

Answer 2

About 1 week or 7 days

Step-by-step explanation:

According to the 3500 calorie rule, one person can lose about 3500 calories or 1 pound in a week if a person cut his 500 calories everyday.

In the given question, if the person loses 500 calorie everyday by no consuming 250 calorie and exercise to lose bout 250 calories. This results in the loss of about 500 calorie per day and as a result of this the person will lose 1 pound of his weight in about 7 days.

Thus, 1 week or 7 days is correct.
