Smaller meals vs. 3 meals a day

So I’ve been trying to figure out my hunger patterns since I have increased my training regimine to working out in the evenings before dinner, usually for an hour and a half. I either do a 90 minute road bike ride or a 60 minute cardio workout (running/elliptical/indoor bike trainer) and 30 minutes of lifting/core. I eat 45g at breakfast around 6:30am and am rarely hunger when lunch rolls around at noon. I eat 45g at lunch and get pretty hungry by late afternoon. After working out, I’m starving! I have been eating 45g at dinner and then another bowl of cereal a few hours after dinner. I’ve been kicking around the idea of keeping my breakfast at 45g, taking my lunch down to 30g, then having mini meals throughout the afternoon and evening, rather than having a big dinner. I know there’s a lot of info out there about eating 6 mini meals a day rather than 3 larger meals, but I haven’t tried it and don’t know how I’ll manage it with diabetes. I’m on an insulin pump and really don’t like to stack boluses. Any ideas? I eat really high fiber foods and relatively low fat meals, with protein at each meal. My nutritionist suggested increasing my protein intake at lunch and dinner to help with hunger.

i eat at 7am, 10am, 1pm, 4pm, 7pm, and 10pm and find that i eat less and have more energy, less carbs at each meal, and less insulin given. i typically have no more than 15-20 carbs a meal. you should try it, it might help.
