I'm trying to gain weight, my daily goal is to get between 4000-4500 calories, I train 6 days a week. I'm never hungry in the morning, I don't feel like eating, in fact, I don't have an appetite before sports, I eat 3k calories or something after sports, and I usually do sports between 11.30-12. Since I can't get high calories at breakfast, it's hard for me to go over 4k calories. Do you have any suggestions to increase appetite?
