I would suggest eating at a caloric deficit aiming to lose 1 lb per week so if you know your maintenance caloric intake just subtract 500kcals per day and if not try multiplying your current body weight in lbs by 12 and use that figure and adjust calories up or down depending on weight loss (weekly) and stick to heavy compound exercises such as squats, deadlifts, bench press, oh press and barbell rows on a 3 day week full body routine with low intensity cardio on your off days
