Does Running Make a Skinny Person Get Skinnier?

Many people, concerned with weight and fitness, often wonder if running can lead to them losing too much weight.

Is it true that running will lead to a skinny person getting skinnier, or is this just an urban legend?

The truth is that running does not cause people to lose weight. Losing weight has more to do with calories burned than the act of exercising overall. 

The real issue for many skinny people who run is not running itself but rather what they eat before and after their workout.

Running does not mean thin people will get slimmer, and skinny people who run will not get any more skeletal if they continue to eat the same amount of calories they did before. 

Likewise, eating healthy and exercising regularly will help a person who is overweight or obese lose weight if the number of calories consumed is less than the number burned by exercise.

Why Does Running Make You Skinnier?

As people move their legs while running, they can burn significant amounts of calories while moving large parts of oxygen to their organs. A person will burn between 100 and 400 calories per mile. 

Is it bad to run if your skinny?
Most people do not realize that they can burn more than 1000 calories in a 5K (3.1 miles) race, depending on their weight and running speed! 

If you are interested in burning the most calories per workout and making the most progress towards your weight loss goals, you can combine training with interval running. 

Interval running involves short bursts of higher-intensity activity followed by short rest periods to allow for more efficient calorie burning and training adaptations.

Make the most of your workout time by combining interval running with strength training.

Aerobic exercise that is performed repeatedly over time is known to help the body burn fat more effectively. 

This is because aerobic exercise changes how fat cells function, which increases your body’s ability to burn fat for energy. 

For example, one of the main reasons skinny people get skinnier when they run is that it helps them burn fat more effectively.

But just because running does not cause skinny people to get thinner, that doesn’t mean that a thin person can’t lose too much weight. Here are some signs that may suggest that your diet is not in check:

  • A person feels lightheaded or dizzy when close to standing up after sitting or lying down. (This occurs because the body has less blood flow to it.)
  • A person experiences more than three bowel movements per day. (The body is losing too much fluid.)
  • A person feels faint or tired when standing up, making it difficult to perform routine daily activities. (The body does not have enough nutrients or protein.)

If you are worried that your diet might be deficient in calories, try adding some peanut butter to an apple before your workout. Eating high-energy snacks can help boost your energy levels during training. 

Another option is to add a scoop of protein powder to a glass of skim milk before you exercise. Protein powder helps the body recover from exercise, and it also helps repair muscle tissue, which can help you lose weight.

What to do if running is causing you to lose weight?

Runners who know they are veering towards the skinny side and who do not wish to become so can change their diets and begin eating more calories. 

People of all sizes need to get the proper amount of calories every time they eat, so running does not need to be abandoned entirely if it is causing a slim person to get skinnier. 

A person can still enjoy running by combining interval training, strength training, and aerobic exercise to help burn fat more effectively.

You can also reduce the number of days you are running each week. For example, instead of running six days a week, you can run three days and perform strength training exercises for the remaining three days.

 It will cut down on your calorie burn and prevent you from becoming skinnier than you already are.

What are the benefits of running for a skinny person?

Besides burning fat, running will also help a person become healthier overall. In addition to helping you lose weight, regular exercise can also reduce the risk of many chronic diseases such as type 2 diabetes and heart disease. 

Does running make you get skinnier?
Running improves cardiovascular health by increasing blood flow, which helps the heart to pump more efficiently. 

Regular exercise can also lower a person’s blood pressure and cholesterol levels, protect against strokes and certain types of cancer, improve sleep patterns and strengthen bones by increasing bone density.


In conclusion, running does not cause a person to get skinnier. If a thin person runs, they will only get skinnier if they continue to eat the same calories as before.

Running does not directly affect weight loss, but it does have an indirect effect by helping a person burn fat more effectively.

 If a skinny person wants to lose weight, they can lower their calorie intake or try interval training to help burn more calories during their workouts.

If you are concerned that you are becoming too skinny, talk with your doctor before you begin running so that they can monitor your progress. 

If a thin person wants to maintain weight, they should watch their diet, perform strength training, and run three times a week for 30 minutes.
