The professional pilot life is demanding physically, you will need to be a bit of a health nut if you want it to work out for you Mike. Getting adequate exercise and whole foods on the road is sometimes a challenge, airliners expose you to thin air, and every six months you are staring at some doctor checking your vitals. Smoking and drinking has to be super light. To be a pro pilot means committing yourself to a lifetime of wellness if you want the best of it. You better like gym workouts in hotel gyms and balanced diets even when you have no access to a grocery store. I have known a few fat pilots and they appear out of place to me. How can you sit in an airplane for 8 hours without taking a crap if you eat that much every day? You can eat well sometimes (I certainly like to), but you had better obey your limits on the road. I used to fly 10 hour shifts in aerial survey airplanes, and up to 12 hour shifts in drop zone airplanes, no way is that going to happen unless you are fit, don't smoke, drink lightly most of the time, and respect some sort of diet.
