I Weight 255 Pounds And I Wanted To Know The Best Way To Drop Atleast 70-80 Pounds By Spring Break?

I would love to be around 180 pounds by spring break going into my prom night and next summer, because i’ve lost about 30 pounds in the last 4-5 months with minimal exercise from more than half that time accept for my bowling leagues about 3 days a week and if theres a better way to quicken up the weight loss process please let me know.
