Calories Burned Examples
The 'Calories Burned Examples' hub demystifies how our bodies use energy throughout the day, focusing on cardio-related activities. From demanding professional roles to targeted fitness sessions, these scenarios provide practical insights into estimating energy output. By examining diverse situations, we aim to highlight the often-underestimated impact of daily movement on overall caloric burn.

Each scenario keeps the starting point, the outcome, and the actual lesson in one place so the page reads like a decision notebook, not a data dump.
- 1
Baseline ride
A 78 kg person cycles at a general, moderate effort (7.5 MET in the 2011 Compendium) for 45 minutes.
The estimate is 438.8 calories burned, a rate of 585 calories per hour, or about 380 calories above what resting would have burned.

MET-based estimates assume steady effort for the full duration. Walk breaks or a slower finish mean the real burn sits below this figure, so treat it as a ceiling rather than a guarantee.

Heavier person, same effort
A 95 kg person does the identical 45-minute, 7.5 MET ride.
The estimate rises to 534.4 calories, a rate of 712.5 calories per hour.

Burn scales directly with body weight because moving more mass costs more energy. The same session yields about 96 extra calories for a 17 kg heavier person, which is why generic calorie charts mislead lighter and heavier users alike.
- 3
Higher intensity
The 78 kg person switches to a hard run at 11.5 MET for the same 45 minutes.
The estimate climbs to 672.8 calories, a rate of 897 calories per hour.

Activity Met
11.5
Intensity is the strongest lever per minute of training time. Lifting the MET from 7.5 to 11.5 adds about 234 calories over the same 45 minutes, so harder efforts pay off when time is short.

A 30-minute run at 6 mph
The 78 kg person runs 30 minutes at 6 mph (10 min/mile), 9.8 MET in the 2011 Compendium.
The estimate is 382.2 calories burned, a rate of 764.4 calories per hour; 343.2 of those are above resting.

The net figure is the fairer one to set against food: about 39 of those calories would have been burned sitting on the sofa anyway. Hills raise the cost too, but pick the MET of the incline activity rather than stacking a multiplier on a flat one.

Calories burned = MET × body weight (kg) × hours. METs come from the Compendium of Physical Activities; 1 MET is about 1 kcal per kg per hour.
