[Other] loosing weight way too fast

Im a 16y/o boy, i am 5,7 and currently weigh 141lbs, 2 years ago i was overweigh and was 180lbs, i started exercising and manage to lose around 20lbs in a year, at the beginning of quarantine i was 166lbs, i continued excercising but then noticed my weigh loss was not consistent, two days ago i used to be 147, two day later i was 142, i am not sure if loosing that much weigh is normal, i really don't think it is, what could cause the weight loss? i haven't done exercise recently, the last time i did was on saturday, and i mostly eat 1,600 calories or 2000 calories a day, why am i loosing so much weight and is it bad?
