Optimal Diet

I've heard about that program, the program designed for athletes I believe. Well I'd like to add some respectable muscle to myself but I'd also like to increase my currently pathetically weak bench, my squat and deadlift are fine but BP needs to improve. source

Yeah, I find some people around here recommend lowering calories too quickly. I would advise against it except as a last resort if all else fails. And that's not to say lowering calories is not a good idea. I just can't see someone with your stats and amount of exercise eating less than 2000 calories per day. As it is I think you might be short on calories at around 2150. Of course, the only way to find out is with some experimentation. But before making too much of an increase or decrease, I'd focus on what you're actually eating. Try to eat mostly complex carbs, lean meats, and healthy fats. If you lose the Snickers and balance out some of your meals and still see no fat loss, it's time to try increasing or decreasing your cals. source

Keto diets usually decrease your appetite due to the fat and lack of insulin spikes from carbs. I would find it hard to eat enough on a keto diet to bulk or even maintain my weight. source

Herbivores do have thicker tooth enamel which allows them to eat carbs without it rotting their teeth. The fact that humans have comparatively thinner enamel is a pretty compelling argument against us eating too much like herbivores. Despite the proclamations of "plant based diet" advocates. source

My friend is six three and has always been skinny. When he was trying to build muscle, he estimated he was knocking back almost 7,000 calories a day. source
