Avoid Eating These 7 Foods Before Going To Gym

Foods can be fuel or kryptonite when it comes to your workout. Eating the wrong things before hitting the gym can leave you feeling sluggish and can sabotage your performance. To ensure you get the most out of your sweat session, steer clear of these 7 foods that can make you feel weighed down and hinder your workout progress. Let’s explore what to avoid for optimal gym performance.

Key Takeaways:

  • Avoid processed foods: Foods high in sugar, trans fats, and artificial ingredients can cause sluggishness during workouts.
  • Steer clear of heavy, greasy meals: Foods like burgers and fries can make you feel bloated and uncomfortable while exercising.
  • Avoid caffeine and spicy foods: These can lead to heartburn and indigestion during your gym session.

Foods That Can Cause Digestive Issues

Beans and Legumes

Cause bloating and gas due to their high fiber content. This can be uncomfortable during a workout and may affect your performance.

Broccoli and Cruciferous Vegetables

One common issue with broccoli and other cruciferous vegetables is that they contain sugars that are hard for the body to break down, leading to bloating and gas.

For instance, broccoli, cauliflower, and Brussels sprouts are known culprits for causing digestive discomfort. It’s best to avoid these vegetables before hitting the gym to prevent any unwanted gas or bloating during your workout.

Dairy Products

One potential issue with dairy products is lactose intolerance, which can lead to bloating, gas, and stomach discomfort. This can be distracting and uncomfortable while exercising.

Foods That Can Cause Energy Crashes

Some foods can cause energy crashes, leaving you feeling sluggish and unmotivated during your gym session. Avoid these foods before hitting the weights to ensure you have the energy you need to power through your workout.

Sugary Snacks

Energy crashes are common after consuming sugary snacks like candy bars, pastries, or sugary drinks. These foods cause a spike in blood sugar levels, followed by a sharp crash, leaving you feeling tired and drained. Instead of reaching for a sugary snack before your workout, opt for a balanced snack that includes protein, healthy fats, and fiber to provide sustained energy.

Refined Carbohydrates

An excess of refined carbohydrates such as white bread, pasta, and pastries can also lead to energy crashes. These foods are quickly digested and absorbed, causing a rapid increase in blood sugar levels followed by a sharp drop. This can leave you feeling fatigued and low on energy, making it harder to push through a tough workout.

Another downside of refined carbohydrates is that they lack imperative nutrients and fiber, which are important for sustained energy and overall health. Opt for complex carbohydrates like whole grains, fruits, and vegetables that provide a steadier release of energy to fuel your workout.

Foods That Can Cause Bloating and Discomfort

Carbonated Drinks

For some individuals, carbonated drinks can cause bloating and discomfort, making them a poor choice before hitting the gym. These fizzy beverages are filled with gas, which can lead to feelings of fullness and bloating. This can be especially uncomfortable during a workout, as it may cause cramping and reduce your overall performance.

If you want to stay hydrated before your workout, opt for still water or herbal teas instead of carbonated drinks to avoid any potential discomfort or bloating.

Processed Meats


Processed meats like sausages, bacon, and deli meats are high in sodium, preservatives, and fats that can cause bloating and discomfort. These foods can be difficult to digest, leading to feelings of heaviness and sluggishness during your workout. To avoid experiencing these negative effects, choose lean protein sources like grilled chicken, tofu, or legumes before exercising.

Another important factor to consider when it comes to processed meats is their high sodium content. Consuming high amounts of sodium before a workout can lead to water retention, bloating, and increased blood pressure. To optimize your performance at the gym, opt for whole, unprocessed foods that are lower in sodium and easier on your digestive system.

Foods That Can Interfere with Hydration

Now, let’s talk about some common foods that can interfere with your hydration levels, making it important to avoid them before hitting the gym.


One common culprit that can interfere with hydration is caffeine. While a cup of coffee or tea can provide a pre-workout energy boost, it’s important to be mindful of its diuretic effects. Caffeine can lead to increased urine output, potentially causing dehydration if not balanced with adequate water intake. It’s best to limit your caffeine consumption before a workout and opt for water or a sports drink to stay hydrated.

Sodium-Rich Foods

Hydration can also be affected by consuming sodium-rich foods before exercising. Sodium, found in high amounts in processed foods, can lead to water retention in the body. This can make you feel bloated and thirsty, affecting your performance during your workout. It’s advisable to steer clear of foods high in sodium to maintain proper hydration levels before hitting the gym.

For better hydration levels, it’s recommended to opt for fresh fruits and vegetables before your workout instead of sodium-rich snacks like chips or processed foods.

Foods That Can Affect Performance

High-Fat Foods

For optimal performance at the gym, it’s best to avoid consuming high-fat foods before your workout. Foods high in fat take longer to digest, which can make you feel sluggish and decrease your energy levels during exercise. Instead of reaching for greasy foods like burgers or fries, opt for lighter options that are easier on your stomach.

Spicy Foods

For a more comfortable workout experience, it’s advisable to steer clear of spicy foods before hitting the gym. Spicy foods can cause indigestion and heartburn, leading to discomfort while exercising. These foods can also increase your body temperature, making you sweat more profusely during your workout.

For instance, consuming spicy foods like curry or hot peppers before a cardio session may not be the best idea, as it can lead to stomach upset and a higher risk of dehydration. It’s best to stick to milder options that are gentle on your digestive system and won’t cause any unnecessary distractions during your workout.

Healthy Alternatives for Pre-Workout Meals

Once again, if you want to avoid the 7 foods you should NEVER eat before a workout, according to Women’s Health Magazine, it’s important to prioritize nutritious options that will fuel your body effectively.

Complex Carbohydrates

With complex carbohydrates, you can opt for whole grains like oats, quinoa, or sweet potatoes. These slow-digesting carbs provide a sustained release of energy throughout your workout, keeping you fueled and focused.

Lean Protein Sources

The key to incorporating lean protein sources into your pre-workout meal is to choose options like grilled chicken, turkey, tofu, or legumes. These proteins aid in muscle repair and growth, ensuring you have the strength and endurance for your gym session.

The right balance of carbohydrates and protein can enhance your performance, support muscle recovery, and optimize your overall workout results.

Hydrating Foods

Hydrating foods such as water-rich fruits like watermelon, cucumbers, and oranges can help keep you hydrated during your workout. These foods are not only refreshing but also provide important vitamins and minerals to support your body’s functions.

Staying hydrated is crucial for maintaining energy levels, regulating body temperature, and supporting muscle function during exercise. Including hydrating foods in your pre-workout meal can contribute to a more effective workout session.


Choosing a combination of complex carbohydrates, lean proteins, and hydrating foods for your pre-workout meal can set you up for success in the gym. By fueling your body with the right nutrients, you can enhance your performance, improve recovery, and maximize your fitness goals.

Summing up

To wrap up, avoiding certain foods before hitting the gym can significantly impact your workout performance. Steering clear of foods high in sugar, fats, and fiber can help prevent discomfort, sluggishness, and cramps during your exercise session. Instead, opt for easily digestible options like lean proteins, complex carbohydrates, and fruits for optimal energy levels and performance. Make smart food choices to fuel your body effectively and enhance your fitness journey.
