ELI5, what happens when you consume more calories than you use, if you are working out? Do you gain weight as muscles, fat or both?
In: Biology
Both.
How much depends on a few things.
1. Training age. If you’re a beginner, you can gain more lean mass. As you get more advanced, your muscle gain will slow down.
2. Training efficacy. Some people are actually training, but a lot of people are “working out.” This is something the typical redditor on r/fitness does. They skip sessions, are constantly deloading to “work on form”, and are hopping from one program to another. These people have poor progress.
3. Calorie surplus. If you’re eating a 200 kcal surplus, then it’s more likely that most of that will be going toward muscle. If you’re eating a 2,000 kcal surplus, you will get very fat.
4. Other. This is things like genetics, meal and nutrient timing. I guess anabolics can be indexed here as well.
