It's all very confusing on what I should do and opinions and I really need to find a weeks routine that I can stick to otherwise I loose faith.
I understand your woes, the gym can be overwhelming at first. Don't worry you'll learn to love it. If you don't want to worry about diet and just focus on lifting then go for it! Once you've got the bug you'll realise that nutrition is incredibly important but I'll admit it took me a while before I started taking nutrition really, really seriously (but honestly good nutrition is just as important as good lifting).
For what it's worth this is what I ate yesterday, I am cutting though so you should want to eat more. I am boring and basically eat the same thing day after day after day, breakfast is always some kind of egg on toast and I rotate about 6 or 7 different recipes for the rest of my day. I am quite anal.
6.30am: Pre-workout shake (1 scoop whey, 350ml skimmed milk), Coffee (horribly strong).
7.00am: Lift
8.30am: Post-workout shake (1 scoop whey, 350ml skimmed milk, 15g Nesquick)
10.00am: Scrambled Eggs (3 medium eggs), 2 slices wholemeal toast
2.00pm: 120g Salmon, 100g Broccoli, 50g Carrots
5.30pm: 300g Chicken Breast, 30g Light Mayonnaise (these were kebabs so vegetables were involved, lots of jalapenos).
9.00pm: Protein Shake
1800 calories, 224g protein (49.8%), 84g Carbs (18.7%), 67g of fat (33.3%)
I order food from ASDA every 2 weeks, costs me about £60 each time. I would definitely buy whey protein though, it's an easy way to get protein when you're in a hurry or just as supplementation if you've not made your numbers each day. Also as you're not cutting you'd probably wish to eat more carbs than me.
Good luck!
