>>1079939I'm very similar physically, 5'6", 140lbs, 27yo with what used to be a lightning quick metabolism that's slowing down (eating less) I used to eat plates of food but these days and my appetite, touching 2000 cal is a miracle.
You use about 1000 cal to keep yourself alive every day plus extra burned from physical activity. So you're using roughly 2200+ cal if you had a 1200 cal workout along with the daily 1000 cal for sustenance.
I started general multivitamin supplements to increase cellular metabolism the past month. It helped me have more energy for longer rides. I also hungered for foods I normally would not eat and tasted much better than normal. The frequency of my hunger matched my projected caloric intake.
