This is such a tricky time with feeding etc. Part of the problem is that they are not as hungry at this age as they have been up til now. So, it might be good to look at his week rather than the day, of eating. Also, one thing that my kids love, that I dont feel quilty about at all, is english muffin pizza. We use whole wheat english muffins, ,cut them open, spread a tomato sauce on, and low fat mozz cheese. I tend to serve it with a cold veggie and dip, but they think they are getting pizza, and I know they are eating a healthy meal. So I guess finding creative ways to serve him might help. They also love fruit salad (meaning apples, oranges, and bananas cut up together.) My kids are older and get to use a toothpick to eat that, but maybe something similar like a special fruit spoon or fork. I also sneak yogurt and fruit into a smoothie, and they think it is a shake! My girls have one for breakfast almost every day. Good luck, just keep offering him a little of everything that you are eating, along with some of his healthy favorites, and you will get there!
