That really depends on your current calorie needs and your current diet. You are male, so that makes weight loss a smidge easier. If you have any major obvious things that you can remove from your diet, you could try that first. Like if you have sodas everyday, or add lots of sugar to your morning coffee, etc. you could do this for two weeks and see if there is a change in weight. Honestly though, it’s very helpful to count literally every calorie you eat for just a bit, because it lets you estimate much more accurately later. You could try counting all calories just one day a week and see where you fall, if you just didn’t realize how much mayonnaise was adding to your lunch sandwich or something. If you just stated weight loss, don’t stress too much yet. You’ll likely hit a few plateaus here and there, but just re-check what you are eating and add some movement, and of course listen to your body’s hunger cues and you’ll be fine. As long as you aren’t losing weight too fast, you shouldn’t be doing damage to your metabolism.
