How Much food does a human consume over a average lifetime?

Answer 1

For a 150-pound person, the average daily consumption of calories would be 12 calories per pound per day x 150 pounds = 1800 calories per day. Now multiply that by the number of days in a lifetime and you'll have your answer. During the first 10 years of life, the number of calories consumed daily is probably less than 1800, but during the teenage years (when the person is growing) it's certainly greater than 1800. So it averages out.

Answer 2

It depends on how much energy the human body expends on a daily base and on a few factors such as age, gender, weight, muscle/fat composition, activities etc. To calculate your daily energy requirements: The Harris Benedict formula. Key: M= weight in kilograms. H= height in centimetres. A= age. AF= activity factor. how do I know what activity factor im at?? Very light AF (sit and stand still most of the day) is 1.3 for men and women. Light active (house cleaning ,slowly walking ,playing Golf most of the day) is 1.6 for men and 11.5 for women. Mild active (walking at faster pase, riding bike, dancing, gym, playing sport such as tennis, riding bike...) is a AF of 1.7 for men and 1.6 for women. Very active (playing tough sports such as Rugby, soccer, long duration aerobic excersize daily, working in a mine...) is a AF of 2.1 for men and 1.9 for women. Now take your details and substitute it in the following equasions: Men: 66.5 + 13.8 (M) + 5 (H) - 6.8(A) Women: 655 + 9.6 (M) + 1.8 (H) - 4.7 (A) Now you get an answer from the equasion.

Take this answer, multiply it by 4.2

Then multiply this by your AF This is the amount of kilojoules you can comsume daily.

To know how many calories this is ,divide your final answer by 4.2 The amount of food your body needs daily ,is the amount of food it takes to sustain this energy requirement of your body. Check labels of products for kilojoule content or get yourself a kilojoule/calorie counter booklet. (If you really want to). If you want to lose wight, subtract 3000 kJ (KJ, NOT CALORIES) from your energy requirement. If you want to pick up weight, add 3000 kJ to your energy requirement and focus on lean meats and complex carbohydrates.

Answer 3

(This is based on an average person)

Assuming three meals a day of about a pound of food and about 700 calories, eaten for seventy years, a person might eat...

3 x 1 x 365 x 70 = 76,650 pounds or about 38 tons. That would fill a 53-foot semi to capacity, and could easily stock a large grocery store.

3 x 700 x 365 x 70 = 53,655,000 calories. That's a lot more than eleven Hot Dogs!

Answer 4

The average person will consume 50 tonnes of food in a lifetime.

Answer 5

25 tons of food pass through the gastrointestinal tract.

Answer 6

On average, a human consumes about 35 tons of food over their lifetime. The actual amount can vary based on factors such as age, gender, lifestyle, and dietary choices.
