Question

In general, a lb of fat is about 3500 Cal. If you receive a surplus 500 Cal per day through your meals (assume the surplus is store as fat), how many lbs of weight gained in a week?

Answer 1

An excess of 500 calories every day for a week would result in an average weight gain of one pound if all excess calories are stored as fat, as there are roughly 3500 calories in a pound of fat.

Step-by-step explanation:

In order to calculate the pounds of weight possibly gained in a week from a surplus of 500 calories per day, we first establish that a pound of fat is equivalent to about 3500 calories. As such, to gain a pound you would have to consume an excess of 3500 calories beyond your body's needs. If a person is consuming an extra 500 calories per day above their body's energy expenditure, we can calculate how much weight they would gain in a week by multiplying the surplus calories per day by the number of days in a week.

The total surplus for a week would be 500 calories * 7 days = 3500 calories. As we know that accumulating an extra 3500 calories results in a weight gain of one pound, it follows that a surplus of 500 calories per day would, on average, result in a weight gain of around 1 pound per week, assuming all surplus calories are stored as fat.

However, this is a simplified version of weight gain. Body mass, age, gender, activity level, and individual metabolic rate can also impact how those calories are processed and either burned or stored within the individual's body.
