Apply deodorant the night before. Studies show it needs time to work to be effective, so in the morning after a shower is less effective. Reportedly deodorant applied the night before will still hold up even after a morning shower.

Years ago I liked soft merino wool jerseys, even in summer. Very comfortable, low odor, didn't need to be rewashed daily.

Nowadays I'm sold on the Pearl Izumi Transfer baselayer, with their fancypants poly "minerale" material. Warm in cold weather, cool during this weekend's ride in warm humid weather, and I've gone as far as five rides between washes -- even then it wasn't stinky. I like it well enough to pony up a bit more cash for a Pearl Izumi jersey from the same material, although my Garneau poly jersey isn't bad.

Diet, medications and supplements make a significant difference in body odor.

I love dark beer but everything stinks afterward, from my urine to my body odor. Lighter ales seem more body friendly, and it's not the alcohol content - some potent ales taste deceptively light.

Strong seasonings and spices contribute to body odor. I love hot spicy foods -- Mexican, Asian and curries -- but my body odor is more pungent the next day. Not unpleasant -- to me -- but noticeable. A diet rich in fatty meats can also contribute.

Some prescription medications produce noticeable body odors. Years ago when I worked in nursing I could tell which patients -- young and old -- were on certain heart medications. Some anti-anxiety and anti-depressant meds can also cause heavy perspiration and body odor. About 20 years ago during a very stressful time I took a then-common anti-anxiety med that caused a ridiculous amount of perspiration in places I'd never sweat before. I even had to put antiperspirant/deodorant on my chest! After a couple of months the doctor switched me to something else and the excessive sweating stopped.
