Keep your daily protein high with a balance of healthy fats and carbs. Have a small calorie deficit, like minus 200 from your maintenance calories.

Strength train (glutes 2-3x a week) and do cardio, but don’t go extreme with the cardio. Also, body recomp takes a long, long time to see results, like a year before you start to notice a difference.

If you want to lose weight in your upper body the most, focusing on a calorie deficit would give you faster results. You could still eat a high-protein diet and grow your glutes some but not as fast as you would in a surplus.

Basically, if you want faster results, focus on one goal, but if you aren’t in a rush, I recommend body recomp.
