Eating and brahmacharya

Since I practice this brahmacharya for 3 weeks or around, when I eat little I feel im full. I eat the same things al before but the quantity itself is half and little, maximum 2 meals a day with just water as liquid. Even though I still continue to eat meat but half the quantity of before. I eat at 12:00 pm and 5 p.m. If I eat as much as before I feel heavy with difficulty to breath.

So when someone practice brahmacharya he needs less food? WHat you think of the meals hours? No eating at morning and night.
