If you increase intensity, you will want to adjust your energy intake accordingly. You need more energy, so you will need to eat more.
When you 'bulk' you eat a caloric surplus to give your body extra room for growth. How you achieve that caloric intake in 24 hours is up to you, really. It is recommended that you keep a muscle-focused spread between the big nutrient families though. Something like 20%fat, 30%protein, 50%carbs.
Without measuring your food intake though, it is difficult to say what is happening. I just advise you to trust your instincts and eat stuff you want to eat... without breaking your carbs-cap for the day.

Increase your fiber intake. Take longer to chew your food. Drink more water.
There is an obsession with protein in bodybuilding that is almost entirely hype and bro science, but supplement sellers are more than happy to feed into the misinformation. Too much protein will definitely make you fat, so be careful about that.
