I’m just confused on how losing weight actually works. So if I cut myself down to 1500 calories a day, I would have to burn like 2000 calories to lose weight? That just seems like a lot of exercising to me, especially because I’m juggling a job and highschool still. Could you guys explain it to me in a better sense?

You don’t burn all 2000 of those calories just from exercise.
Everyone has a BMR (basal metabolic rate) which is the amount of calories they burn a day just by existing basically. This is calculated based on height, weight, age & gender, – you can calculate it [here](https://www.calculator.net/bmr-calculator.html). This will be a good estimate, but there are other factors: for example, people with higher muscle mass will have a higher BMR, and people who don’t sleep much/don’t get enough deep sleep will burn less.
