Hello! Kudos to you for responsibly watching what you eat. Not many people try to even stop for a moment and think about what they are putting in their bodies. Your exercise depends on your goal and yes it is quite challenging especially if you're exercising for muscle mass. It's tiresome and you need to wait months before results appear in the mirror. Provided that you train with weights consistently, you'll gain roughly 1-2 pounds of pure muscle per month. But that's what makes it all worth it. Enjoy the journey and don't think too much of the destination. Cheers!
