Increase protein intake on workout days?

[evinahmad86]

Started cycling since september and finally added a diet to my training. I've already lost about 3 kg in the last couple of weeks, but I'm strugling with my macro intake. I've been using the iifym diet since it's something that really motivates me but i am confused about what macronutrient i should increase on workout days. I eat about 1.5g protein per kg bodyweight on a daily basis and have read that eating more isn't necessary because the body won't process any extra intake. Is this true or should i take in more proteins when i burn more kcal?
