I don't think so. I chose 28s for better dampening. I'd prefer to run 23s but my back wouldn't like it for long. The 25 gator skins I'm using on my now commuter bike ( inside joke with my friends) are not too bad just want to try 28s and see if there is more relief to be had. Roads here are pretty rough from tractors and cattle trucks tearing them up. One of the guys I ride with is using 42s iirc and those things while huge smooth out the bumps he says.

I have long ago used 28mm tires but i want put on my road bike 23mm. i have hear some pro riders use 25mm tires but i not know if that is truth

When you ride a lot, you become more efficient and burn fewer calories riding the same distances.

Also, lean mass is what burns a lot of calories. It's possible he still has a high body fat percentage, and below average percentage of lean mass.

As Grant Petersen would say, a cyclist is basically sitting on a chair and spinning their legs really fast. The momentum of pedaling and of the wheels spinning is what carries the bicycle forward: this doesn't require a lot of exertion on the cyclist's part, especially once the bike is up to speed.

I see lots and lots of heavy set riders on the rec trails when I ride.

I have zero data to support any claims and anything said is purely conjecture. My buddy however did swap 23s in place of the 25s he was running to help keep on the wheels of a fast group ride. He could hang in the flats but was dropped in the hills. But not bad enough where he couldn't make up the distance. It's a 36 mile ride with just shy of 3k climbed. They do it 19-20 av speed. he weighs 20-50 pounds more than most of the group and rides a 2003 felt. The others are riding the 6-9k carbon bikes except one guy on An olderTitanium.

My my buddy seems to think the 23s gave him an advantage over the 25s, whether that's real or perceived idk. It is likely I will never find out as those guys drop me at, hello.

Well when I ride a lot I drop weight, and can eat & eat, and still drop weight maybe I have not hit the zone were the weight remains a constanst number.

Wider tires, in theory, have less rolling resistance than narrow tires but their aerodynamics are worse (especially on narrow rims) and they weigh more. Unless you're trying to win a race, it probably doesn't matter whether you use 23mm or 28mm tires.

That doesn't happen for everyone. I did 163 miles last week and weight is up today. Genetics are a ***** sometimes.

Thank you for the very helpfull answers. I not race but when i ride in flats i try go the faster i can. In hills too i try that

The pros run 24-25mm tyres, but they're also tubular tyres that are a smoother ride in any case compared to equivalent clinchers. I've ridden on 'standard' 19mm wide rims and the new trend 23mm wide rims, and the improvement in ride quality is noticeable, but only on certain road surfaces. Most of the time, there was no perceivable difference. Cornering was improved and ride on rough chip seal was improved as well. Also worthy to note, the difference between a thinner race tyre and a more durable puncture proof tyre can be felt too in a similar way.
