There are viruses that get people to gain weight. They might do that by getting people to eat more. They might also do that by getting people to burn less calories.
The hypothesis that viruses are responsible for the obesity epidemic is a possible one. If it would be the main cause literal CICO or Mass-In-Mass-out would still be correct but not very useful when thinking about how to combat the epidemic.
The virus hypothesis has for example the advantage that it explains why the lab animals with controlled diets also gained weight and not just the humans who have a free choice about what to eat in a world with more processed food.
Overeating due to addicting processed food also doesn’t explain why people fail so often at diets and regain their weight. In that model it would be easier to lose weight longterm by avoiding processed food.
The obesity epidemic must be due to either overeating or lack of exercise, or both.
No, the healthy body has plenty of different ways to burn calories then exercise and is willing to use them to stay at a constant weight.
