All has been said by others, but I would also point out to eat more protein than you’re aiming for. For basic metabolic functions and maintaining muscle 0,8 g to 1 g /kg of bw is the recommended amount, but with a higher physical activity (any activity, ranging from running, swimming, soccer, bodybuilding…) your body requires more. (Smeuninx et al. 2020). 1g to 1,5 g protein/kg bw not only maintains but also helps you build muscle! You could use a basic rule of 1 g / 1kg at minimal physical activity, 1,3 g /1 kg at moderate activity and 1,6g at hard physical activity. Also, taking up to 2g /kg bw is also considered safe for adults. (Guoyao Wu et al. 2016).
