It's actually on the lower end for trained individuals. I'm 35, been dabbling in the gym since I was 18. I had more muscle mass than the average Joe, just a lot of fat covering up my muscles. An average rec tennis player that lifts at the gym 2 to 3 times a week and plays tennis the same, 0. 5g to. 75g is more than enough. An actual body builder 1g to 1.6g per lb of body weight.
But the macro nutrients pale in comparison the criticality of ensuring a 500-700 caloric deficit every day. This is why most people fail because they have no idea how much food they're putting in their mouth.
Once you know a large banana is always 120 calories, 1 cup of rice is 200 calories, 1 cup cooked 80/20 ground beef is 340 calories, or even one tasty Popeyes chicken sandwich is 700 calories, it gets much easier to manage. Literally I just a 1 cup measuring cup. After a while, you can just eyeball it.
Best part is, once you reach your goal weight and body fat percentage, you increase your caloric intake to a maintenance level. My goal is 180 right now, so at maintenance I would eat about 2800. When I was 217lbs, I was eating an average of 3000 a day, for who knows how long, but that is all it took to get this fat over 2 two 3 years.
