You need to eat food to fuel a workout, which is a great excuse to devour your favorite snack before hitting the gym. As David Wiener, training and nutrition specialist at fitness app Freeletics pointed out: “If you exercise on an empty stomach, your body won’t have enough energy to perform at its best.” But – and this is a pretty important but – it’s just as bad to eat the wrong thing before a workout as it is to eat nothing at all. And that’s because “all your energy will go towards digesting that food” instead of powering your exercise.
“While spicy foods may satisfy your taste buds, they should be avoided before exercise for a couple of reasons. Firstly, spicy food can result in indigestion or heartburn which can leave you in pain and having to abandon a workout. Secondly, spicy foods can lead to increased cramping which again could force you to halt a workout, or affect the amount of effort you’re able to put in.”
Avoid dairy products such as yogurt and cheese before getting your sweat on. These foods, while rich in protein, can result in gas, bloating and even diarrhea.
“It’s well known that fizzy drinks are nutritionally void and more often than now laden with sugar, so it shouldn’t be too surprising that they’re a poor choice for your pre-workout drink. Their high sugar content and carbonation can make you feel bloated, and lead not only to a sugar crash but also cause stomach cramps and nausea during your workout.”
“Cruciferous vegetables like broccoli, Brussels sprouts, and cauliflower are important vegetables to include in your diet, but they will wreak havoc on you while you exercise. This is because these vegetables are high in raffinose, an indigestible carbohydrate that can trigger abdominal bloating and excessive gas.”
“Inadequate amounts of sugars and carbohydrates in your system before a workout can lead to lethargy and fatigue, especially when you’re exercising, but you must pay attention to the source of sugar, and as always do your best to avoid refined sugar found in many manufactured products. Instead, opt for glucose which is found in carbohydrate-rich foods or fructose which is found in fruits and vegetables; your body uses these types of sugar far more effectively and efficiently.”
“Avocados should be avoided pre-workout due to their high-fat content (even though avocados are filled with good, mono-saturated fat). In addition, avocados are rich in fiber, and this combination takes the body longer to digest which could result in stomach cramps.”
Foods that are rich in fiber like wholegrain bread, whole-wheat pasta and oats are good for you to keep you full for longer and regulate the digestive system. But, before workout these foods should be a big no no! The reason being that it takes a long time for the body to digest and can lead to gastrointestinal distress. This can result in bloating, nausea, gas and stomach cramps which can be problematic during your workout.
