Well the distance you are doing does not require much in the way of carbohydrates.

In bicycling, you fuel your exercise either by burning fat or burning carbohydrates. The rule of thumb is that you burn between 30 cal and 55 cal per mile depending on speed and weight (rider+bike). So 10 miles is only going to burn 300 calories and that is not a real big deal.

If you are riding at a low level of intensity (just starting to breathe differently), then you will burn more fat. If you are riding nearly flat out, you will burn nearly 100% carbohydrate. After intense rides, I find that my hunger cravings especially for sweet stuff just goes off scale. On long less intense rides, I have less of a hunger effect.

Also everyone responds a bit differently both to food and exercise. I can get up and reel off 50 miles before breakfast, but that is me and I wouldn't advise that for the general population.

A problem with exercise is that a lot of people go out and exercise a little and then eat a lot more to "reward" themselves.

What has worked for me, is to get rid of the junk in my diet (fats & sweets) and not increase my food much if any and exercise.

I can lose weight at an incredible rate if I wish. I was on a 2 week tour in the Rockies where we rode about 70 miles per day and climbed around 4000' per day and I lost 10 lbs in 2 weeks. I ate enough carbohydrates to replenish my muscle glycogen but otherwise, I was reasonably careful (I still ate a fair bit). But some people on the same tour GAINED weight because they came in and went out and ate a big old cheese burger and fries with a soft drink and then had a large hot fudge sundae to top it all off! I suppose that no matter how much you exercise, you can eat enough to eliminate any possible benefit.
