“Research shows that diets that are too low in protein can deplete the immune system. So I make sure to get protein-rich foods throughout the day, especially fish, eggs and yogurt.”
—Douglas Kalman, PhD, RD, director of nutrition and applied clinical trials at Miami Research Associates
3. Wipe out
“Gyms are crawling with sweaty towels, dirty sneakers and other germy grossness. Instead of sitting directly on a mat or bench, I’ll place a clean towel on it first. Any equipment that I have to touch—like free weights or bicycle handlebars— I’ll clean first with antibacterial wipes.”
—Franci Cohen, group-exercise instructor and owner of Fuel Fitness, in Brooklyn, N.Y.
