The number of calories burned while serving food depends on your weight and amount of time spent on your feet. Serving food for your family burns fewer calories than a food-service job with long shifts that requires lifting trays.
Formula
METs is a number that represents how much energy you exert during an activity. According to PeerTrainer, the formula for calculating calories burned while serving food is METs x 3.5 x weight in kg ÷ 200 x duration in minutes. To convert your weight to kilograms, divide pounds by 2.2. A 125-pound person weighs 56.8 kg.
Energy Output
Based on the Physical Activity Tracking Guide by Dr. Bill Haskell, serving food at home has a METs value of 2.5. An occupation that allows little resting time and requires you to continuously lift up to 20-pound items has a METs value of 4.0. An occupation that requires you to carry items while standing and using stairs has a METs value of 5.0.
Calories Burned
If you weigh 125 pounds and serve food to your family for about 10 minutes, you'll burn 25 calories. If you're a waiter, on your feet for a six-hour shift and using stairs, at 125 pounds, you will burn 1,796 calories, according to Dr. Gily.
