If you listen to some self-proclaimed exercise experts on social media, they swear that working out on an empty stomach burns more fat.
But it’s a common misconception that exercising in a fasted state improves performance or burns more calories, said Abby Langer, a dietitian in Toronto.
“The research shows that in terms of gains, it doesn’t really make much of a difference,” she said.
Does that mean you should load up on protein and carbs right before a workout? No, that’s not true either.
Here’s a look at when — and how — you should eat, before, after or even during a workout. (And remember, experts say what you eat is more important than when you eat.)
The calories in food literally are energy, so you need them to fuel your body for a proper workout. Eating too much too soon beforehand, though, can be problematic.
Exercising diverts blood from organs including the stomach to the muscles, said Langer, author of “Good Food, Bad Diet.” So exercising on a full stomach affects the digestive process, which could cause cramping or even make you feel sick.
That’s particularly the case with meals high in fat, protein or fiber, which take longer to digest than carbohydrates. Langer recommends eating a high ratio of carbs beforehand and waiting two to three hours before intense exercise.
“You don’t want to eat a big steak an hour before you play hockey,” she said.
If you exercise first thing in the morning or before dinner, it’s OK to have a carb-rich snack like a banana with peanut butter or yogurt with fruit beforehand. It will give you the energy to perform well, and you can fuel up afterward with a full meal.
That steak may serve you better afterward because that’s when a higher ratio of protein is easier to digest, said Krista Austin, a physiologist in Colorado Springs.
Austin said if it will be an hour or longer before you can have a full meal, it’s better to have a high-protein snack in the meantime to help curb your appetite. The reason has little to do with muscle recovery or nutrient absorption: Rather, people who are too hungry make poor dietary choices.
“A lot of people get very hungry about an hour after exercise, and you don’t want to do that,” said Austin, author of “Performance Nutrition: Applying the Science of Nutrient Timing.” “You want to catch it early, or you go and overeat.”
But it’s another myth that you need to grab a protein shake within minutes of finishing to build the biggest muscles, Langer said.
Many exercise enthusiasts point to what’s known as an “anabolic window” of about an hour within exercising that the body is primed to repair muscle. For the average person, you have a much longer window, and nutrient timing is less important than making sure you consume some protein at every meal, Langer said. The body needs a continuous supply of amino acids like protein for muscle repair and maintenance, she said, which means about 25 to 30 grams at every meal, depending on various factors.
“Prioritizing that will help with goals, either muscle building, satiety, weight loss, all of that,” Langer said.
Most people who are eating enough throughout the day don’t need anything during a workout. Langer and Austin said the threshold is about an hour of intense exercise. Longer than that — say you're training for a marathon — and you can benefit from a carb-rich snack in the middle.
Instead of focusing on when to eat, Austin said to focus on what and how much. She cautioned against overcomplicating the topic and recommended following the USDA’s My Plate recommendations for a balanced diet.
“The biggest thing we need to teach people is that nutrition is simple,” she said. “Maybe you need to stop focusing on the concept of nutrient timing and just make sure that you’re consistently eating throughout the day and focus on health.”

YANGON, Myanmar (AP) — Myanmar's powerful 7.7 magnitude earthquake has killed over 1,000 people, as the death toll keeps climbing amid rescue efforts.
The military government said Saturday that 1,002 people have now been found dead and another 2,376 injured, with 30 others missing.
The earthquake struck midday Friday, followed by several aftershocks including one measuring a strong 6.4 magnitude.
In Thailand, the quake rocked the greater Bangkok area, leaving six people dead, 26 injured and 47 still missing.
Several countries, including Malaysia, Russia and China have dispatched rescuers and relief teams.
Here is the latest:
Russia's Emergencies Ministry said 120 rescue workers have been sent to help search for victims trapped in the rubble and assist with clean-up/
According to a statement Friday evening, two aircraft were on their way from Moscow to the earthquake-stricken country, with anaesthesiologists, psychologists and canine units also on board.
The city’s chief executive, John Lee, also extended his condolences to the earthquake victims in a Facebook post on Saturday
Meanwhile, Taiwan’s National Fire Agency said a rescue team of 120 people was on standby for possible deployment. The team included rescue personnel, doctors, nurses, a vet, six search-and-rescue dogs and 15 tons of equipment.
Taiwan and Myanmar don’t have official ties. Most countries don’t recognize Chinese-claimed Taiwan as a country as Beijing prohibits other nations from having formal ties with Taipei.
An additional rescue team of 82 people left Bejing, hours after a different team of emergency responders from the Chinese province of Yunnan, bordering Myanmar, arrived in the earthquake-stricken country.
Additionally, 16 members of the Chinese civil relief squad Blue Sky Rescue Team in the city of Ruili, Yunnan, departed to Muse City in northern Myanmar to help with relief efforts, according to state broadcaster CGTN. Chinese authorities also sent a first batch of 80 tents and 290 blankets early Saturday.
Meanwhile, Chinese President Xi Jinping extended condolences to Myanmar’s leader Min Aung Hlaing.
The earthquake was felt in parts of China's Yunnan province, though casualties were limited. Two people in Ruili suffered minor injuries and 847 homes were damaged, according to authorities. Some high-rise buildings and older houses in urban areas were also partially damaged, but power and water supplies and transportation and communications lines have been restored.
New Zealand’s Foreign Minister Winston Peters wrote on X that his government would support relief efforts “via the International Red Cross Movement."
“Our thoughts are with all those who have lost loved ones, and to everyone else affected,” Peters said Saturday.
New Zealand’s foreign ministry said all embassy staff in Yangon and Bangkok were accounted for and no New Zealanders had been reported hurt or killed.
South Korea will send the aid through international organizations to support recovery efforts following the recent earthquake.
The Foreign Ministry stated on Saturday that Seoul will closely monitor the situation and consider additional support if needed.
