It really varies by person. Have you ever used a calorie counter? I use
MyFitnessPal. You can enter in your height, starting weight and goal weight, and how active your lifestyle is, (they give examples for each intensity to make this easier), and it will give you a calorie goal to hit as well as carbs, fat, protein, etc. Doesn't mean you necessarily have to use it to keep track, but you can at least complete that step and get a good idea for yourself. Hope this helps. Good luck to you!
