Plateauing!! Help!

(M20 SW295) First post here; I’m stuck at 250bw in my weight loss journey. I had this problem the first time I lost weight, also at 250, and what worked then isn’t working now. Any tips on how to overcome plateaus?

Please avoid intense life style changes in replies, I am not too worried about my weight, just worried that I’m doing something wrong. I’m much happier than I was 4 months ago and I’m much healthier. I have a good diet, eat 2-3 times a day but still snack on fries at work. TLDR I eat good and workout hard, why doesn’t the scale go down?
