You are on point my friend. Staying lean is a pain in the ass lol.I use to compete in some amateur bodybuilding about 10 years ago. Kinda messed me up when it comes to dieting. I work in a gym so getting in a workout is easier for me than most. However, I'm not one of those guys that shaves his legs and arms and poses in front of the mirror. I lift 5 days a week, eat protein with every meal, eat healthy fats and carbs, sometimes I eat junk food (because it's good) and do some mild cardio. I'm what you would call "thick" or "built" but not necessarily lean. I just don't have the desire to keep track of my intake to keep my body fat down around 10% because I'm naturally not lean to begin with. But, I'm more fit than you would think. My point is, exercise and make it something you like to do. Don't get caught up in the minor stuff and start off simple. I'm a huge advocate of working out in the gym because it's a destination. The energy is better than at home and you make friends who you look forward to seeing. There is so much equipment (at least here at my gym) that you can't really get bored. Eat every 3-4 hours (protein, healthy carbs, and healthy fats), drink a gallon of water per day and have lots of sex and you'll be good as new in a few months. "You can't go anywhere if you don't get on the train."
Meal frequency does not matter though. At the end of the day it is calories in calories out. What gym do you go to?
