1800 calories per day, is it okay?

Hello, I’ve been dieting on an 1800 calorie diet and have had great results so far. I have been losing at least 1-2 pounds per week. While this sounds good, I’m afraid of losing muscle. I understand muscle loss is inevitable when dieting, but I do not want to take it to the extreme and look super skinny afterwards.

I don’t think I’ve experienced much muscle loss, and I have been taking measures to prevent too much such as resistance training, high protein, and taking amino acid supplements. The diet has went well so far, I don’t get extreme cravings at all.

I’m male, 6’3, and weight 186 lbs currently. I’m mostly sedentary besides my workouts three times per week.
