Ok, so an assumption that I wanted to start out with is that calories-in, calories-out (CICO) is the only way to lose weight. This is not up for debate in this thread. However, I wanted to discuss things that may make a difference in either the CI side or the CO side and help an individual lose weight.
For instance: More sleep leads to more energy which means you may workout or move around more, which increases in calories out.
Or: If you eat healthier foods you are more satiated on fewer calories, so you eat less (fewer calories in.)
What are some things that you think affect weightloss because they may affect CICO?
Note, this doesn't mean that any of these things are universal, because again, CICO is what actually changes things, but I've noticed people have some things which help them achieve their calorie and activity goals.
