You must have sweated off
hundreds of calories during that Spin class, so it’s totally okay to
indulge in a bowl of ice cream when you get home—right? Not so fast.
Research shows that people tend to reward themselves with rich foods and
large portions after exercising, and that they often eat back all of
(if not more than) the calories they just burned. There’s nothing wrong
with small snack or a filling dinner after exercising, says Emily Brown,
RD, a wellness dietitian at the Mayo Clinic in Rochester, Minn. and
former professional runner. But before you dig in, you have to
understand your body’s true nutrition needs so you don’t end up gaining
weight despite all your hard work. Read on for the smartest ways to
refuel—and silence that rumbling belly.
Work out right before a meal
If
you’re always hungry after you exercise—regardless of whether you ate
beforehand or how many calories you burned—try to schedule your workouts
before one of your main meals, says Brown. That way, you can refuel
with calories you would have consumed anyway, without having to add
extra snacks into your day.

This strategy can work
regardless of whether you’re a morning, noon, or nighttime exerciser.
Have a small snack when you wake up and eat a larger breakfast after
your a.m. run; hit the gym at lunchtime and pick up a sandwich on the
way back to the office; or prep your dinner ahead of time so you can
just heat it up when you get home from an evening barre class.
Make your workout fun
Thinking
about exercise less as a chore and more as something you do because you
enjoy it can help you eat less afterward, according to a 2014 Cornell
University study. Researchers led volunteers on a 1.4—mile walk, telling
half of them that it was for exercise and half that it was a scenic
stroll. The “exercise” group ate 35% more chocolate pudding for dessert
than the “scenic” group. In another experiment, volunteers were given
post-walk snacks, and the “exercisers” ate 124% more calories than those
who were told it was just for fun.

Pair protein and carbs
When
you do need a snack to recover from a tough sweat session, Brown
recommends a 4:1 ratio of carbohydrates to protein. “This will allow you
to begin to replenish your energy levels and repair muscle damage
resulting from the workout,” she says. For workouts less than an hour,
keep your snack to 150 to 200 calories total—an open-faced peanut butter
and jelly sandwich, a slice of turkey and cheese on crackers, or a
handful of trail mix, for example. If you worked out for longer than an
hour and aren’t eating a full meal soon, aim for half a gram of
carbohydrates for every pound of body weight. A 140-pound person, for
example, should refuel with 70 grams of carbs and about 18 grams of
protein. (An energy bar or protein shake, plus one of the healthy snacks
above, should fit the bill.)
Get milk
Low-fat
dairy is another great recovery food with plenty of protein to help
tide you over until your next mea., says Jim White, RD, owner of Jim
White Fitness and Nutrition Studios in Virginia Beach. Plus, studies
have shown that refueling with dairy—low-fat chocolate milk,
specifically—helps improve subsequent athletic performances better than
traditional sports drinks.
Stop eating out of habit
Sometimes,
overeating after exercise is more a consequence of routine than
anything else. “When you consistently consume a 500-calorie smoothie
after you finish up at the gym, you start to get into that habit of
consuming a smoothie no matter how long or intense your exercise was,”
says Brown. Her solution? Choose different snacks for different
workouts—the shorter the duration, the fewer calories you need to
replenish— and always pay attention to your hunger cues. “It’s important
for weight loss and weight maintenance to get in tune with your body
and learn to eat in response to hunger, versus eating in response to
boredom, stress, or the idea of rewarding yourself for exercising.”

Don’t trust your tracker
Activity
trackers like the Fitbit and Jawbone have become a trendy way to
estimate physical activity expenditure throughout the day. But a 2014
Iowa State University study found that not all devices are accurate in
estimating calorie burn during workouts. The least accurate device, the
Basis Band, had an error rate of 23.5%. Even the most accurate trackers
can still only provide an estimate of true calorie burn, says Brown, and
it’s not smart to base your refueling strategy entirely on their
calculations. “You also want to get in the habit of eating in response
to hunger and stopping in response to comfortable fullness. This is
dictated less by numbers and more by listening to your body.”
Snack throughout the day
It
may seem counterintuitive, but eating more throughout the day may be
your ticket to consuming fewer calories overall, especially if you tend
to pig out post-workout. “Incorporating two to three healthy snacks
throughout the day will help regulate hunger between meals, increase
energy, and keep metabolism bumped up,” says White.

Don’t overestimate
You
may feel like you burned a million calories during your Spin class, but
research shows that we tend to overestimate our energy expenditure
during exercise—by as much as four-fold, according to a study from the
University of Ottawa. When volunteers were then asked to eat back all
the calories they’d just burned, they tended to consume two to three
times more than what they’d actually expended. One high-tech way to
prevent overestimating your calorie burn: wear a heart-rate monitor.
Most of these include a sensor worn around your chest and a wristwatch,
which sync together wirelessly. Still, if your heart-rate monitor says
you burned 600 calories, that’s not automatically an excuse to scarf
down a 600-calorie sundae. “If you are trying to lose weight, you will
need to consume fewer calories than you expend,” Brown says.
Drink water as soon as you’re done
Replacing
the fluids you lost during a workout should be priority number one,
Matt Fitzgerald, a certified sports nutritionist and author of Diet
Cults and The New Rules of Marathon and Half-Marathon Nutrition. “Having
a lot of water in the belly also reduces appetite—not a lot, but a
little,” he says. “Guzzle water as soon as you walk in the door to
quench your thirst and take up space in your tummy.” Just don’t consume
massive quantities. Taking in too much water (or any fluid) can cause
water intoxication due to excessively low levels of salt in the body.

Ask yourself if you really need to eat
You’ve
probably heard that it’s important to eat something immediately after
your workout to help your muscles recover. But the truth is, you might
not need to, says Brown. Say you’ve just finished up a tough run and you
know you’d like to hit the gym for weight training in the morning. In
that case, yes you should have something to eat. “But if you’re taking a
few days off before your next hard workout, you probably don’t need to
worry about refueling quickly,” Brown explains. If you’re not hungry,
then don’t force yourself to eat, she says. “You’re going to eat those
calories eventually, so why not save them for your next meal when you’re
actually hungry?”
Refuel along the way
For
workouts lasting longer than two hours—like a long bike ride or a
marathon training run—sucking down a gel or sipping a sports drink will
keep you from feeling ravenous afterward. “Research has shown that
people eat fewer calories after exercise when they take in carbs during
exercise,” says Fitzgerald. “In fact, their total calorie intake for the
24-hour period that includes the workout comes out to be slightly lower
if they fuel up during it.” (Also important: You won’t run out of steam
halfway through your training session.) Try to consume 30 to 60 grams
of carbs—that’s 120 to 240 calories—every hour after your first hour.
Avoid anything with protein, since it takes longer to for the stomach to
digest.
