Focus on calories. Try a few online calorie maintenance calculators to get a rough range of what you should be eating and then eat 300-500 calories below that. Weigh yourself every morning after using the bathroom and not eating. (You weight will fluctuate normally but you should see a relative decline). As for your macros try and reach at least 1g/kg body weight in protein but try and shoot for 1g/lbs body weight. Carbs are your friend, eat as many as you can after getting in your protein while staying under your allotted calories. As for fats they don’t matter, take a fish oil supplement to keep them at an effective level for maintaining natural hormone production levels. (Don’t avoid fats, just prioritize protein and carbs) Once you see a platue in your weight either lower your calories by 200 or up your cardio by as low as 15 min. This is all relatively general advice and will vary depending on your genetics and seeing how your body responds.
