It seems useless to eat protein powder three times a day for fitness.
If you eat on an empty stomach in the morning, the effect will not be very good (most of it will be converted into heat energy). It is best to eat after a normal diet; Just eat it before going to bed at night! In addition, it is recommended not to drink water and take a bath immediately after exercise (this will relax the already tense muscles); Twice a day is enough. Eating too much and too often is not recommended!
