M 22y/o 178 lbs, 19% BF 150 BP 285 S 305 DL

I’ve recently lost about 10 pounds of fat and added about 5 lbs of muscle if I had to estimate. I’m starting to see a lot more def in my arms and legs, shoulders, and obliques. Still extra fat hanging on the love handles and lower stomach. I’ve done a lot of reading on how to shave the BF % down and I’m aiming for 15 or 16. What’s the best way to achieve this? I’ve seen tons of different advice, intermittent fasting, one meal a day, cutting carbs, strict keto, going paleo, more cardio, fasted cardio, HIIT, and supplements like L-carnitine and quadracarn. It seems like there’s so many strategies and I’m wondering if anyone’s had a similar BF reduction and could tell me what worked and what didn’t.

I’d love to get to my goal by May, is this achievable during a college semester? Thanks in advance.
