I'm trying to gain strength right now for the next 3-4 months. I'm at ~84 kg right now. Bodyfat % is probably ~15-16%.
What should be my approach in these 3-4 months in terms of eating? Should I eat like a bull everyday regardless if I go to the gym/I consume calories that day or should I just eat a lot in the training days/after training and keep a low calorie, low carb intake in my rest days?
eat one big meal on rest days, the rest of your meals should be low carb high + mod/high protein + moderate fat snacks.. on training days, same thing, but consume more in the meal after training (which is after he post workout shake).. so basically two big meals on training days.
Should I take a protein shake that's 50% protein 50% carbs after my training/in my training days instead of the 90% protein one that I'm taking right now?
wouldn't worry too much about that, but i'd lean more towards the 50/50 split, you'd want more carbs than 10% thats for sure.
Do you think I should aim at re-composition in this 3-4 month period (meaning - trying to build muscle in my training days in terms of nutrition and lose fat in the off days, maybe doing some running, cardio etc)? Or should I go all out into muscle building and forget about cardio and stuff, with the idea of shedding fat later?
definitely do the cardio, i'd say your focus is more on putting on MOSTLY lean mass with minimal fat, rather than losing fat & gaining muscle.. so, putting on mostly lean mass will have your body composition improving, and you'll have less fat to 'cut' when you reach your goals 3-4 months from now.. cleaning up your diet so it's less frequently carb heavy & getting in the cardio will help you achieve this.
so, on your rest days, for your snacks, you want something that is low carb + high protein + moderate fat... such as 2% milk + protein.. i imagine you will have a "blood thirst" kind of feeling once you start eating like this, and that's a bad sign.. once you are satisfied with a lower carb snack like that throughout the day, you'll be seeing some major physique changes. You could obviously use something else too, such as green veggies + small chicken breast or a sandwhich or something like that.. the point here is, eat most of your carbs in one meal, then eat them in much lesser amounts throughout the day.
avoid stuffing your face all day
peace
