Assuming you lift:
- 2g protein per kg of target bodyweight
- 1g fat per kg of target bodyweight
- remaining calories carbs
If you don't lift 1.5g protein per kg of bodyweight. If stress level is high, add 0.5g proten per kg of bodyweight.
If your target bodyweight is far above your current BW, say >10%, it is sensible to split the journey into more managable chunks <5%.
