What do you mean by 15/1? 15 what to 1 what. Excuse me for my ignorance.
15/1 means your macro for eating should be:
For every 15 calories you consume, you should have 1g of protein
IE 1500 calories a day = 100 grams of protein minimum a day
2700 calories = 180 grams of protein minimum a day
when bulking, protein content is key. The higher the amount of protein, the more you have for potential muscle gains(as long as its constrained by the overall calorie number)
just because you need 180g protein doesnt mean gorge on 3500 cals of food, anything you dont use for muscle is converted to fat
15/1 is a maximum ratio so ideally you want something closer to 10/1(probably the best you can manage eating normal food)
