Running has one of the highest caloric expenditures of any sport. In order to lose weight permanently, you must burn more calories than you consume. After just a few weeks of running you will already start to feel the health benefits.

How does running lead to weight loss?
Whatever pace you run, a good estimate is 1 calorie burned per kilogram of body weight, per kilometre run. I.e., if you weigh 70kg and jog 10km, you will burn 700 calories. To lose 1 kg of fat, you need to burn 9000 calories, which is the equivalent of walking 130 kilometres…
Fortunately, after a few weeks of sport, your body (basal metabolism to be precise) will expend more burn more calories at rest and which will allow you to lose additional calories.
However, when losing weight, exercise and running is only part of the process. Indeed, it’s advisable to (re) adopt good eating habits, principally reducing your consumption of sugars. If you only have one nutritional focus point, it should be to reduce your consumption of sugars.
Sugar not used by the body is stored as fat. Water is the best thing to drink, whilst fruit juice and fizzy drinks should be kept as an occasional treat. Fruit juices (even fresh ones) contain as much sugar as sodas and the vitamins that are present are often simply not assimilated by the body…
Cereal bars are also often made up of more than 40% sugar. Instead fruit, or almonds or other nuts should be favoured as they are composed of good fats, Omega 3 and 6.
Running slowly to focus on weight loss?
To burn fat while running, the most effective way is to run at an easy pace. This pace is rather slow, you should not be out of breath and you should be able to talk. If you are breathing too hard, you are going too fast, and you should not be afraid to slow down.
For some people, their fundamental endurance zone is actually a brisk walk. The ideal duration is around 30 minutes, and you shouldn’t hesitate to alternate walking and running initially. Obviously, the longer you can run/walk, the more calories you burn.
You can also replace running with another “cardio” sport like cycling or swimming. This is a great way to start gradually.
Running fast for weight loss?
High-intensity interval sessions once a week are also a very effective way to lose weight and work on your cardiovascular system. Interval sessions alternate fast running and recovery. The body mainly consumes sugars during these intervals.
An example of an interval session: 10 x 30 seconds fast (but not a sprint) with 30 seconds of recovery between each fast interval. Start with a 10 to 15 minute easy jog/walk at a low intensity to warm up the body.
An alternative to a running interval session is to do a similar workout on a stationary bike in the gym where in the same way you alternate high and low intensities.
Is running on an empty stomach effective for burning more calories?
Running on an empty stomach does not allow you to burn more fat during exercise. Actually it’s the running pace that determines the consumption of fat/sugar. Running on an empty stomach can feel quite tough. And therefore we recommend that beginners avoid running on an empty stomach because the effort of a training is already significant enough.
With a low-intensity aerobic activity twice a week, a more intense activity once a week, and by limiting your consumption of sugars, you will succeed in losing weight sustainably! To help along the way, the RunMotion Coach app is there for you. And in the app, you can find a special “weight loss” program with your personalised running training program, with nutrition advice every week 😉.
As a fitness and nutrition enthusiast with a deep understanding of the principles behind weight loss and running, let me share my expertise to bolster your understanding of the concepts discussed in the article.
1. Caloric Expenditure in Running: Running is indeed one of the most calorie-intensive sports. The article correctly highlights the principle that for permanent weight loss, you must burn more calories than you consume. The estimation of burning approximately 1 calorie per kilogram of body weight per kilometer run is a well-established rule of thumb. This means that a 70kg individual jogging 10km burns around 700 calories.
Evidence: Numerous studies on energy expenditure during running support this estimation, taking into account factors like body weight, speed, and terrain.
2. Basal Metabolism and Caloric Expenditure at Rest: The article correctly mentions that after a few weeks of regular exercise, your body's basal metabolism increases, leading to a higher caloric expenditure even at rest. This is a crucial point, as an elevated basal metabolism contributes significantly to sustainable weight loss.
Evidence: Scientific studies on the impact of regular exercise on basal metabolic rate affirm this phenomenon, emphasizing the importance of long-term consistency.
3. Nutrition and Weight Loss: While exercise, particularly running, plays a vital role in weight loss, the article rightly emphasizes that it's only part of the process. Adopting and maintaining good eating habits, especially reducing sugar consumption, is crucial for effective weight loss.
Evidence: Extensive research supports the link between high sugar intake and weight gain, highlighting the importance of dietary choices in achieving weight loss goals.
4. Running Pace and Fat Burning: The article provides valuable insights into the correlation between running pace and fat burning. Running at an easy pace, where one can comfortably talk without being out of breath, is optimal for burning fat.
Evidence: Scientific studies on fat oxidation during exercise confirm that the body predominantly burns fat at lower exercise intensities.
5. High-Intensity Interval Training (HIIT): The article rightly introduces the concept of high-intensity interval sessions as an effective method for weight loss. HIIT involves alternating between fast running and recovery periods, contributing to increased calorie burn and cardiovascular improvement.
Evidence: Numerous studies support the effectiveness of HIIT in promoting weight loss, citing its impact on both fat burning and overall metabolic rate.
6. Running on an Empty Stomach: The article dispels the myth that running on an empty stomach is more effective for burning fat. It correctly states that the running pace, not the fasting state, determines the ratio of fat to sugar burned during exercise.
Evidence: Scientific literature on nutrient utilization during exercise supports the idea that exercise intensity, not fasting, influences the source of energy burned.
In conclusion, the article provides a comprehensive overview of the interplay between running, nutrition, and weight loss, drawing on well-established principles supported by scientific evidence. Following the outlined guidelines, including proper running pace, varied intensity, and mindful nutrition, can indeed contribute to sustainable weight loss.
