Chances are you aren’t happy with progress b/c you aren’t eating enough.
You don’t need a ‘diet’ where all you meals and macros are laid out the week before hand. But if you’re anal about that shit - I’m so clever - you can.
A good starting point for you, without any history, would be 3000-3500 calories per day. Eat 300g protein a day and fill in the rest with the best fat/carbs you can afford.
If you aren’t gaining weight after 2 weeks, add 250-500 calories per day. Gaining too much fat, most likely not, subtract 250 calories per day.
You can still be healthy and look good with out eating expensive, 100% organic, grass fed, omega3 blah blah blah food.
Im 6ft, 225lbs and I am still skinny as hell. Although it is better then when I was 175lbs, Im no where close to being considered big. As a very general guideline MAF14 started you off. All I can say is make food your best friend.
