The Claim
Physical exercise increases total daily energy expenditure by approximately 5%.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who engage in physical exercise burn about 5% more energy per day than those who do not.
See the scientific wording
Physical exercise increases total daily energy expenditure by approximately 5%.
When a person exercises regularly, their muscles grow larger and work more efficiently, which makes them burn more energy even at rest. This extra energy use comes from the muscles needing more fuel to maintain their new size and activity, and from the body moving more during daily tasks because it has become stronger and more capable. The total energy burned each day goes up because the body is using more fuel to support these changes.
What the research says
2 studiesPeople who started exercising burned about 5% more energy each day than before, even though they ended up eating a bit more, which is why they didn’t lose as much weight as expected.
People who exercised regularly for 12 weeks burned about 270 extra calories per day — way more than the 5% increase claimed. So yes, exercise boosts daily calorie burn, but even more than the claim says.
