Greetings gentlemen

I have been doing Brazilian Jiu Jitsu for around two months now, and have one tab on my belt. I am entering a local competition in February. It is win by submission only, and anyone can enter. There are specific categories for belts, so as to prevent people like me fighting black belts.

I was talking to a friend of mine at my gym. He is the exact same age and build as me, only an inch or so taller. He wants to drop from 82 kg (181 pounds) to 76 kg (168 pounds). I weigh the same as him, and after talking to one of the coaches about it, he told me to seriously consider losing weight.

I restarted going to the gym 3 times a week. I do BJJ twice a week plus yoga on a Sunday. At the gym, I do the C25K program, and I am in week 6 of 8 on that. I started the Stronglifts 5x5 program for weights.

I squat 72.5 kg (160 pounds), bench 42.5 kg (94 pounds), bent over row 45 kg (99 pounds), deadlift 60 kg (132 pounds) and military press 22.5 kg (50 pounds).

I am at 24% body fat. I am also going to post this on r/BJJ and r/Fitness under a throwaway, but since everyone here is or should be lifting, I wanted your advice. I want to drop to 76 kg, and ideally 16% body fat. What diet and exercise changes should I make? I eat a Middle Eastern heavy carb heavy meat diet.

Thanks in advance.
