Eating is probably the last thing you think about when you're about to HIIT it hard at the gym, but making sure you're fueled with the right foods will help you make the most out of your workout. Noshing on the wrong foods can be a recipe for gas, bloating, diarrhea—none of which you want to deal with when you're doing deadlifts and downward dogging. To help you make every rep count and increase your calorie-burning prowess, we rounded up the best pre-workout foods. And while you're at it, check out our list of 12 Things You Should Never Drink Before a Workout. Because what you sip can make or break your sweat sesh.
It's true: Spinach is muscle fuel. But not because it instantly turns you lean and sexy. Researchers from Rutgers University found that a compound in the leafy green increases protein synthesis by 120 percent, helping your muscle tissue to repair itself faster after you work out. The problem, however, is that you'd have to eat Popeye-sized quantities to experiences dramatic results (we're talking almost 2 pounds of the iron-packed veggies a day). The good news is that spinach isn't the only option when it comes to foods that will help you lose weight and feel better than ever—even when you're not exercising.
Drinking cold water before and during exercise can help improve your endurance. In a British study, cyclists who drank about 30 ounces of a chilled drink in the half hour before riding in a hot, humid environment-and smaller amounts as they rode-were able to bike 23 percent longer than riders who downed lukewarm liquids. Drinking cold water may be the most direct way to reduce core body temperature, so it takes you longer to heat up and slow down. Better yet, rev up your calorie burn with these detox waters.
Pineapple & Papaya
Both of these tropical fruits are loaded with bromelain and papain, enzymes that not only help break down proteins for digestion but also have anti-inflammatory properties to speed up your post-workout recovery. For a full list of the best fruits for your belly, click here.
Australian researchers found that cyclists who took fish oil for 8 weeks had lower heart rates and consumed less oxygen during intense bicycling than a control group did. The fatty acids in fish oil need to become incorporated into muscle and heart cells to have an effect, and that takes weeks of consumption—so either take fish oil pills each day, or try to eat fish rich in fatty acids multiple times a week to see similar results.
Brazilian scientists found that participants who consumed three cups of green tea every day for a week had fewer markers of the cell damage caused by resistance to exercise. So drinking a few cups every day may help your muscles recover faster after an intense workout.

People who ate 20 more grams of protein every day than the group average had 6 percent lower waist-to-hip ratios. Not a fan of meat? Here are 7 Best Meat-Free Proteins That Boost Weight Loss.
Instead of reaching for a Gatorade, go for some chocolate milk. A study in the International Journal of Sport Nutrition and Exercise Metabolism found that folks who drank chocolate milk before riding on stationary bikes were able to last 49 percent longer than participants given a generic carb-replacement drink.
Not only can coffee boost your workout performance, it can also help with recovery. University of Georgia researchers found that taking a caffeine supplement equivalent to two cups of coffee post workout actually reduced muscle soreness more effectively than pain relievers. How so? Caffeine was found to deactivate pain receptors.
A study published in the Journal of Nutrition discovered that high-protein dairy can increase exercise-induced weight loss. To come to these findings, participants enjoyed six daily servings of dairy while the control group didn't. The group who ate more dairy maintained more lean muscle regardless of sharing the same fitness regime.
The small but mighty nuts are effective at both whittling your waistline and improving exercise performance.

Yes, we are looking at you egg white lovers. Next time you reach for an egg as a post-workout meal leave the yellow stuff in there, because a recent study published in The American Journal of Clinical Nutrition found that whole eggs stimulated muscle synthesis more than egg whites when eaten directly after resistance exercise. The egg whites and whole eggs had the same amount of protein, but healthy fats and other nutrients in the yolk promoted more efficient use of protein found in the whites.
A 2017 ESPN exclusive revealed peanut butter and jelly sandwiches to be the pre-workout snack of choice for NBA players. The sandwich is a staple for a reason, the carbs deliver players and athletes the boost of energy they need to perform while protein from the peanut butter helps in muscle recovery.
A study based off of data from the National Health and Nutrition Examination Survey found that consuming oats was consistent with a lower body mass index and better overall nutrient intake. Throw a scoop of your favorite protein powder and nuts into your oatmeal for a pre-workout meal packed with all the carbohydrates, fat, and protein your body needs to work at its full potential.
Cottage cheese contains high levels of casein protein, which is the best post-workout snack for a late night pump before bed because it is slow digesting. A study in the Journal of Nutrition also found dairy proteins like those in cottage cheese to have a superior effect on protein synthesis of soy proteins after workouts.
A study in The Journal of the American Pain Society found that ginger is effective in reducing inflammation and disability induced by eccentric exercise.
Brown rice is chock full of complex carbs, which help fuel your workout with lasting energy. The whole grain is also a great source of muscle-benefiting magnesium.

Muscles require a complete protein—with all nine essential amino acids—for proper rebuilding and growth. While meat is known for packing in all nine amino acids, there are vegetarian sources of complete proteins that do the trick, one of them being small but mighty chia seeds. In addition to packing complete protein, chia seeds also contain omega-3s (ALA specifically), which help torch fat.
A study in the American Journal of Clinical Nutrition found that iron can help reduce fatigue related to strenuous exercise by circulating oxygen to your muscles. Kale is a wonderful source of the nutrient, so why not whip up a chopped salad before your next run?
Lentils are loaded with iron—nearly 3 grams per 3.5-ounce serving—which can help increase muscle efficiency. And that's not all: The legume is chock full of magnesium, a mineral that's essential to muscle development, energy production, and carb metabolism.
A study in the Journal Physiology of Sport and Exercise discovered that insufficient water intake can prevent essential amino acids from entering muscle tissue. Not only will your workout sessions suffer, but insufficient liquids in your body will also hinder fat breakdown.

Bananas are the ultimate pre-workout snack, notorious for providing a potent energy boost. "Bananas are made up from three different types of sugar (fructose, glucose, and sucrose) which get absorbed into your blood at different speeds, meaning that you will get a quick boost of energy and won't suffer a slump as the sucrose will keep your blood levels steady," Nutritionist Frida Harju tells us.
For all-day energy and a potent workout boost, Monica Auslander, MS, RD, LD/N, founder of Essence Nutrition recommends a homemade matcha latte. "Matcha has a significant amount of caffeine and is a great alternative for folks who hate coffee or put horrible things in there (creamers!).

Additionally, salmon is one of the few natural sources of vitamin D, which may also help combat fatigue, causing you to feel more energized." Talk about a tasty workout boost!
Complex carbohydrates, like those found in sprouted, whole-grain bread will help you power through your workout thanks to the energizing B vitamins, fiber, and protein. Since it takes our bodies longer to break down complex carbs, opt for popping a slice into the toaster for long-lasting energy.
