Can I Eat Whatever I Want If I Workout? Will I Gain Weight?

A man sits on a sofa, wondering if working out means he can eat pizza and chips, stuck in the "Can I Eat Whatever I Want If I Workout?" dilemma.

The general rule in dieting is that if you eat more than you burn, you’ll gain weight and if you burn more than you eat, you’ll lose weight. But then, does this mean you can eat whatever you want if you workout regularly? The answer is no. 

Why You Can’t Eat Whatever You Want When You Work Out

While you might believe that working out gives you a free pass to eat whatever you want, that’s not the case.

Regular exercise does increase your calorie needs, but the quality of the food you consume is just as important as the quantity.

Indulging in high-calorie or nutrient-poor foods simply because you’ve exercised might not give you the results you’re hoping for. Your body needs a balance of carbohydrates, proteins, and fats to function optimally.

And while your workouts do contribute to how many calories you burn, they do not counteract all the effects of eating foods high in sugar and saturated fat.

This balance is important if you aim to lose weight or improve specific aspects of your fitness.

Here are the reasons why you should be mindful of your diet.

Caloric Surplus Negates Workout Benefits

To lose weight, you must burn more calories than you consume. Overconsuming calories, therefore, leads to a surplus making weight loss unattainable. This undermines your workout efforts.

Junk Food Undermines Physical Performance

Nutrient-poor foods can harm your workout performance and recovery. It leads to sluggishness and reduced endurance, ultimately hindering progress.

Unhealthy Eating Affects Motivation and Energy

What you eat directly influences your energy levels and motivation. Unhealthy foods cause energy spikes and crashes that affect your workout routine and overall fitness goals.

Exercise Alone Can’t Compensate for Excessive Eating

Regular exercise cannot compensate for regular overeating.

Despite engaging in daily physical activity, consuming more calories than the body needs can still result in weight gain over time.

Research indicates that overeating, even for short periods, can lead to fat gain, with studies showing that a caloric surplus of about 1400 calories per day can result in approximately 0.2 pounds per day of fat gain. 

Poor Diet Leads to Mental Health Declines

A poor diet can indeed have negative effects on both physical health and mental well-being. This impacts your ability to stay focused and motivated during workouts, hindering your fitness gains.

Consuming highly refined carbohydrates can lead to obesity and diabetes, impacting psychological well-being.

Diets high in refined carbohydrates and sugars with a high glycemic index increase depressive symptom risks through blood glucose fluctuations and stress hormone releases.

High-calorie, saturated-fat diets can trigger inflammation linked to mood disorders, highlighting the impact of poor dietary choices on mental health.

You Risk Overtraining with Insufficient Nutrition

Studies have shown that proper nutrition helps to prevent overtraining syndrome and optimises athletic performance.

Poor nutrition can increase the risk of overtraining and injury. Your body won’t get the necessary nutrients to repair and strengthen after exercise. 

Choosing Short-Lived Pleasures Leads to Negative Long-Term Health Impacts

Opting for immediate gratification by eating high-calorie, processed foods often contradicts long-term health objectives, even with exercise.

These foods, rich in refined ingredients and artificial substances, contribute to weight gain, type 2 diabetes, inflammation, and other health issues. This emphasizes the importance of avoiding ultra-processed foods for overall well-being.

Establishing Healthy Eating Habits

I find it easy to establish and stick to healthy eating habits if you follow the basics.

Do not only focus on the quantity of the food you eat but also the quality.

Prioritize nutrient-rich foods, stay hydrated, and plan your meals. This leads to more effective and sustainable outcomes, especially with a consistent workout routine.

Here are the healthy eating habits to adopt:

Prioritize Nutrient-Dense Foods for Fuel

Your body requires a wide variety of nutrients to function optimally. Choose foods rich in vitamins, minerals, and fiber, such as fruits, vegetables, and legumes.

These foods give your body the necessary fuel for daily activities and workouts.

Hydrate with Water, Limit Sugary Drinks

Water is crucial for maintaining bodily functions, including metabolism and physical performance.

Aim to drink at least eight 8-ounce glasses of water a day, more if you exercise heavily. Avoid beverages high in sugar, as they can add unnecessary calories and lead to energy crashes.

Incorporate Protein-Rich Foods and Fermented Foods in Your Diet

Protein is essential for muscle repair and growth. Include a variety of protein sources such as lean meats, fish, tofu, and legumes in your daily meals.

Fermented foods like yoghurt, fermented soy products and kimchi introduce beneficial bacteria to your gut, supporting digestion and overall health.

Plan Your Meals and Snacks

Take control of your diet by planning your meals and snacks. This can help you avoid hunger-induced decisions that may lead to less nutritious choices.

Remember to pair carbohydrates with protein or healthy fats to keep you full and energized.

Choose Whole Grains and Healthy Snacks

Opt for whole grains over refined grains to maximize your nutrition intake.

Foods e.g., brown rice, quinoa, and whole-wheat pasta contain more fiber and nutrients than white sources.

Select nutrient-dense snacks like nuts, seeds, or a piece of fruit.

Cut Down on Processed Foods

Processed foods are high in unhealthy fats, sugars, and sodium.

Minimize your intake of these foods to prevent consuming empty calories that can hinder your wellness goals.

Instead, reach for whole-food alternatives that support your diet and exercise regimen.

Avoid Eating in Front of Screens

Mindful eating can help you better recognize hunger and fullness signals.

Avoid distractions like TV or smartphones during meals. This prevents overeating and improves digestion, ultimately contributing to a healthier dietary pattern.

How Much Exercise Can Counteract Unhealthy Eating?

There’s no magic number of exercise minutes to fix an unhealthy diet. While an intense workout might offset a single indulgent meal, consistent unhealthy eating habits will lead to weight gain over time, regardless if you work out every day.

Create sustainable healthy eating patterns and complement them with regular physical activity.

Together, these can improve your health without counting every calorie “burned” through exercise.


In conclusion, the belief that you can eat whatever you want as long as you work out is a myth that overlooks the critical balance between diet and exercise. Regular physical activity does increase your caloric needs, yet it doesn’t mean you can eat nutrient-poor, high-calorie foods without consequences.

Ignoring the quality of your diet can lead to not just physical health issues like weight gain and decreased physical performance, but also mental health declines due to dietary impacts on mood and well-being.

Therefore, adopting healthy eating habits such as prioritizing nutrient-dense foods, staying hydrated, planning your meals, and cutting down on processed foods is crucial. This holistic approach supports both your immediate fitness objectives and overall long-term health.
