Jogging has long been considered the “golden exercise” to burn calories and improve cardiovascular health. Many people believe that if you just run hard and eat healthy, losing weight will become easy. However, in reality, many people fall into a paradox: running regularly, dieting seriously but their weight does not decrease, even increases. This makes many people confused and lose motivation to exercise.
In fact, gaining weight when jogging is not a sign of failure. It can be the result of many different factors, from diet, recovery habits, to natural changes in the body. So what is the cause and how to fix it?
Why do you still gain weight when jogging and eating healthy?
Gaining weight when jogging and eating healthy does not mean you are failing. This could be the result of overeating, poor food choices, post-workout hydration, or because you’re building muscle.
Here are some of the reasons why:
1. Eating more after running
Running causes the body to expend a lot of energy, creating a strong feeling of hunger. If you “compensate” with high-calorie foods like pastries, fried foods, or sugary drinks, the calories you take in can quickly exceed the calories you burn.
Solution: Prepare a nutritious but low-calorie post-run snack like Greek yogurt, fresh fruit, boiled eggs, or a smoothie made from vegetables and nuts.
2. The “reward” effect after exercise
A common habit is to allow yourself to eat more after a run: “I ran 5km today, I deserve some pizza.” This mentality can cause you to unintentionally eat more calories than you need.
Solution: Change your mindset: running is not an excuse to indulge, but rather part of a healthy lifestyle. You can reward yourself in other ways, such as taking a break, reading a book, or watching a movie.
3. “Healthy” but high-calorie foods
Many foods that are considered healthy are still high in calories, such as nuts, peanut butter, fruit smoothies, or lattes. If you don’t control your portion sizes, they can still contribute to weight gain.
Solution: Watch your portion sizes and pay attention to your total daily calories. Prioritize green vegetables, lean proteins, complex carbohydrates, and limit sugary drinks or processed foods.
4. Gain muscle while losing fat
One reason you gain weight even though you’re leaner is because you’re gaining muscle. When you run and strength train, your body tends to build muscle. Because muscle weighs more than fat, the scale may go up, but your body will be firmer and healthier.
Solution: Don’t obsess over the number on the scale. Look for changes in your waistline, feeling stronger, increasing your stamina, and clothes fitting better. That’s what really matters.
5. Lack of balance between training and recovery
Running burns a lot of energy, but if you cut back on food too much to lose weight quickly, your body will become tired, prone to injury, and slow down your metabolism. Over time, this can cause your weight to “get stuck” or even increase.
Solution: Make sure your body is getting enough carbohydrates to regenerate energy and protein to repair muscles. Rest and sleep are just as important as your workout, as that’s when your body regenerates and burns energy efficiently.
6. You drink a lot of “hidden” calories
Some people focus on controlling their meals but forget that drinks also contain calories. Sodas, energy drinks, even coffee with milk or high-sugar smoothies can add hundreds of calories per day.
Solution: Prioritize water, herbal tea or black coffee without sugar. If you drink smoothies, limit added sugar, replace with green vegetables, less sweet fruits and unsweetened milk.
7. Your body retains water after exercise
After long runs or high-intensity workouts, your muscles can become mildly inflamed, leading to water retention. This causes temporary weight gain, even though you haven’t actually gained fat.
Solution: Don’t worry too much if your weight increases for a few days after a heavy workout. Drink enough water, supplement minerals and give your body time to recover, and your weight will stabilize again.
8. Running but little movement outside of work
Running burns a lot of energy, but if you spend the rest of the day sitting, your total calorie burn will still be low. This is why some people work hard but still have trouble losing weight.
Solution: Increase light movement outside of work, such as walking more, climbing stairs, or simply standing up and walking around after every hour of work. These small activities also contribute to an effective calorie deficit.
