David Katz, M.D.
“Most of the relevant priorities came naturally to me. The hard one was to embrace the inevitability of failure in both personal and professional efforts.” — David Katz, M.D., founding director of the Prevention Research Center at Yale University
Neghar Fonooni
“The most important thing I’ve learned is to completely dissociate my physique from my happiness. Whether I gain or lose five pounds has nothing to do with my inherent happiness or my zest for life, and I can absolutely love my body no matter what it may look like at the moment. I’ve been through pregnancy, hormonal imbalances, orthorexia, and multiple health issues—and my body has been different every single step of the way. What’s kept me grounded—and ultimately healthy—is the knowledge that my physique doesn’t dictate my worth. ”
Adam Bornstein
“There is no perfect diet, workout, exercise, or overall health plan. It’s the big secret that all the smartest people know, and yet it’s the least shared health message. Make your focus what works for you, and anything you do in fitness and nutrition becomes a lot more effective and a lot less stressful.”
Chris Powell
“An incredible doctor friend of mine and I were talking about how to get people to eat totally healthy and incorporate exercise into their lives. He said this, and when it comes to lifelong change, it is so true. Small changes over time lead to extraordinary long-term results!”
Alan Aragon
In other words, missing one workout or going overboard on the ice cream one night (or maybe two) isn’t going to cancel out all the times you chose healthy. It’s the sum of all those small decisions that truly makes a difference in overall health and happiness. (And just for the record, eating dessert should never make you feel guilty.)
Alan Aragon is a continuing education provider for the Commission on Dietetic Registration and National Strength & Conditioning Association.
Jeanette Jenkins
“When you choose to perceive a situation in life, you then have to live in that perception, so if you choose to look for the negative, then you will live in a negative experience, and if you choose to look for the positive, then you will live in a positive experience. The choice is yours, so choose wisely.” — Jeanette Jenkins, founder and president of the Hollywood Trainer fitness company
Marion Nestle, Ph.D., M.P.H.
You can make it even easier with these 40 unexpected ways to add veggies to every meal, these plant-heavy detox recipes, or these super simple zucchini noodle recipes.
Marion Nestle, Ph.D., M.P.H., is the Paulette Goddard Professor of Nutrition, Food Studies, and Public Health at New York University.
Gretchen Rubin
“This is the best advice for happiness.”
Tony Gaskins, Jr.
Becoming more organized is actually easier than you’d think, and it’s possible to squeeze healthy habits into even the busiest schedules (this list is proof).
Tony Gaskins, Jr., is a motivational speaker and life coach.
Shaun “T” Blokker
“My grandfather told me this, and while he was a pastor and his mental drive was focused on religion, I was able to transfer that meaning to me to be a positive thinker. Making my thoughts more positive help me become stronger mentally, which helps me push past any barrier, be it physical or mental.”
Mike Boyle
“To paraphrase the Golden Rule… ”
Kathryn Budig
“Nothing in excess is good for us, so I always make sure to balance my hard work with recovery, rest, good food, and play.” — Kathryn Budig, international yoga instructor
