Dude, you are too thin. 170kg I felt thin when I weighed 58kg, but now I feel a little muscular when I weigh 70kg. Eggs are an important food to supplement muscle synthesis. I eat six eggs a day, including egg white and yolk, what's more, yolk has high cholesterol. That is to say, those who only eat and don't exercise have no such worries at all. How can Phelps eat 20 eggs a day and still not pay for it? As long as you have enough exercise, you will run out of nutrition. You need to eat more and practice more if you want to gain weight. The key is persistence.
