Running for Weight Loss

How to consistently lose weight with running.

1. A Hard Truth

First of all, a hard truth: if you are overweight it means you are eating too much. Now, mind my words. I didn’t say you are eating a lot, I simply said you are eating too much.

Let’s start from the beginning.

Food is our source of energy; it is the fuel that allows us to perform every task: from basic ones such as breathing, pumping the blood around the body and walking around to complex ones such as carrying the TV up the stairs or running when you’re late for the bus.

Our bodies are efficient machines. We come from a time when food was scarce and reducing waste was key to survival. Fat is the way your body stores extra energy. When you eat more than what your body needs, your brain doesn’t go “oh well, this is extra, I don’t need it – let’s get rid of it”. What your brain thinks is “Fantastic! Extra energy! Let me store this in case tomorrow you won’t be able to hunt a bison down so we can use this energy instead”.

Your body then proceeds to process that extra food and transform it into fat, which then gets stored under your skin a bit all around your body: your gut, (man) boobs, bum, legs and face.

You see, your brain doesn’t see fat as a bad thing. It sees it as a fantastic way to ensure survival in case you won’t be able to find food in the future.

2. The Good News

The good news is: the reverse process also applies and it’s also very efficient: if you don’t introduce enough fuel (energy/food), your body will promptly go and take it from its fat reserves.

 

The Caloric Deficit

We keep talking about energy and fuel because it’s an easy way to picture it. In science, this has a name which is CALORIE. A calorie is a unit of measure of energy. So you can replace everything you read as “fuel” in the paragraphs above with “calorie” and it will still be exact.

And why is this important? Because we can calculate it and plan our weight loss around it !

A Caloric Deficit represents the amount of calories that your body doesn’t get through food and has to go and find in its fat storage… (almost) literally burning it.

It’s actually very easy: eat less calories than the calories you burn and you will shed fat away.

3. Your Basal Metabolic Rate

The Basal Metabolic Rate (BMR) is simply the amount energy (calories) you burn each day at rest. Even when you think you aren’t doing anything, you are using energy to breathe, move around, keep your muscles active.

The BMR varies by individual and depends on a lot of factors such as gender, height, weight, body composition (fat vs. muscle)…

There are many formulas to calculate your BMR and you can find a good calculator here: http://www.bmi-calculator.net/bmr-calculator/

Let’s use me as an example. I am a 34 year old male, 6.2” for 185 lbs weight. My BMR is 1927 calories per day.

That means that if I do nothing all day and I eat 1927 calories, I will neither gain or lose weight. But we do indeed do something every day. Just walking around and moving will put more more or less at 2,200 calories (use the link above to calculate your values!).

So if I want to lose weight, I have two choices:

  1.  Eat less THAN 2,200 calories
  2.  Be more active and consume MORE than 2,200 calories

4. How running HELPS you lose weight

Running is a calorie-consuming activity. When you run you contract and release many muscles – in the legs, feet, arms… your heart rate goes up to keep feeding oxygen and nutrients (through the blood) to the muscles.

Do you remember the caloric deficit? By running you increase the calories you burn during the day. This is a ballpark figure, but it’s estimated that running 1 mile burns 150 calories (it’s a very average value and depends on many factors including your weight, running efficiency…).

So if I run 3 miles a day I will burn an extra 450 calories each day. It means if I keep eating the same I will lose weight!

How much weight? It is calculated that 1 pound of fat equals 3,500 calories. 1,800 calories a week (running 3 miles a day 4 days a week) means half a pound of fat per week. This if you eat to your daily caloric need. Chances are, if you are overweight, you eat more than that already.

Is it less than you were hoping? Don’t worry, you can lose more.

 

Slow and Steady wins the (weight loss) race.

Running is an amazing way to lose weight, but you need to understand that you need to build it up. When you start running you probably won’t even be able to run those 3 miles. Most beginners’ running programs will have you run-walk 3 times a week for a month before you can run 3 miles.

STICK TO IT! After all running is an endurance sport and as such, patience is what brings the best rewards. Don’t rush distances/speeds you are not ready for yet. They will come and it will all make it better very soon.

 

5. Why running WILL make you lose weight

As we said before, your running condition will improve with time and three things will happen:

  1. You will be able to run further
  2. In just a couple of months you will be able to run 8 miles in one session. Run 3 times a week for 8 miles each session and your weekly calorie expenditure will be 3,600 calories or a full pound of fat!

  3. You will be able to run faster
  4. Running faster will make you burn MORE calories per each mile.

  5. You will put on muscle

Remember your BMR (Basal Metabolic Rate) ? It’s higher when you have more muscles. That is because muscles are alive and need constant feeding just to be maintained, while fat just sits there.
Running will slowly but surely build muscles – especially in your legs. These muscles will consume extra calories even when you are not running, just because they are there !

To summarize: running is very hard at the beginning and you might not see results for a while (in terms of weight loss, but of course things like your cardio efficiency will be immediately and noticeably better). But keep running and in just a few months you will be a fat burning machine !

 

6. How to MAKE SURE you will lose weight (or, “mistakes to avoid”)

In the beginning the amounts of calories you will be burning is going to be low. And you will be very tired, because running is an effort that you are not used to.

You will feel like you spent more energy than you actually did.

Remember. One 3-mile run will burn 450 calories (approximation!). After the run you think “I need to re-hydrate, let me have a Gatorade”. A bottle of Gatorade has 300 calories. Does it make sense to run 3 miles to only reap the benefit of 1 of them? Energy drinks have a place, but when you run less than 1 or 2 hours, stick with water.

Also, many people think “Well, I ran this morning, I can treat myself to a candy bar!”. Do you know how many calories in a standard bar of Snickers, Mars or Lion? Almost 300. Two of your three miles are gone.

If you want to lose weight while running, don’t add calories to your diet. Not at the beginning.

What to eat ?

I am not a cook, but in our household we started cooking some of the recipes from the Metabolic Cookbook by Karine Losier. They’re easy to cook, tasty and with a decently low amount of calories – we don’t see it as a diet, just food to cook for the family. Try it out!

 

Last word of advice: don’t take shortcuts.

a) Running is a taxating sport for your body. If you aren’t patient and increase mileage/speed too fast you can get injured. This means pain, no running and no weight loss.

b) Decreasing your caloric intake is a good step, but don’t take it too far. You can easily and healthily burn 2-3 pounds of fat a week. But if you keep underfeeding your body, your brain will start breaking down the muscles instead of the fat (the logic is “we don’t have enough energy to survive! Let’s cut down those high-maintenance muscle fibers!”).

  • Good article. I gained 5 lbs while training for my half marathon because I was eating too many carbs throughout training. The amount of calories you burn depends on your current weight. You may be able to burn 450 calories in 3 miles, but since I’m much shorter and weigh less than you I would have to run 4.3 miles to burn the same number of calories. But I may not have to burn as many calories as you to lose weight because I would have a lower BMR anyways.

    • Hi Shorty, you are right the number of calories burnt varies greatly depending on the person! I included my example and I want to invite people to do the math for themselves but most of all try on experience! Thanks for passing by and leaving your comment !

  • Hello , I’m beginner in running and I would like to ask you few questions.Usually I’m runinning in the morning, could you tell me should I run before breakfast or after breakfast ?

    • Hi ! I also run mostly in the mornings!

      On a general level, running before or after breakfast doesn’t matter in terms of calories.

      It does have an impact though. It’s long to go through here, but the thing is that your body runs on carbohydrates while it finds them, and turns to burning fat once the carbs are finished. So in theory running on an empty stomach is beneficial for fat loss, but in reality this only matters if the run is over 40 minutes in lenght (and at a slow pace). Running on “fat” is not something your body likes to do, so you need to gradually train it to do it efficiently.

      • Hi! I’m referring to an answer you gave to a previous question. How do you train your body to run on fat?

        • If you eat no carbs, and fat is the only thing to burn, your metabolism will adapt to burn it faster. But for most people it takes 6-8 weeks of hell to get rid of the bread/pasta addiction.

  • This is a easy to understand yet informative article. Although I run about 20-30 miles per week, I hadn’t heard of the BMR before. Thanks for writing this up.

    Oh and by the way, I don’t believe ‘taxating’ is a word. :)

  • Really well written article. I have been running for about seven years and I find that when training hard for a race my mind tells me that I need to eat a lot more than the bit of extra food that I actually need, so I consequently end up loosing weight very slowly. I always see a much quicker weight loss by cutting calories and increasing activity rather than one or the other.

  • Hi, I’m a beginner in running and I run three days a week – Monday Wednesday and Friday for 30-35 minutes without stopping by one month. I want to ask if I begin to walk on four days a week to run and how much time should be lowered to less weight. Thank you.
    Sorry for my english.

  • Can anyone help, please.

  • hi there sir.., i normally run 10-12km per day in the morning 3-4 times a week this is my way of balancing my diet coz i like to eat chocolates and chips..wat do you think is this healthy for me?? and as a long time runner i begun to have a plantar fasciitis to bad for me :( but that doesnt stop me from running i recently finished a fulmary 42.195km at 4km my right foot was in severe pain but i manage to finished the race..,any suggestion on my plantar fasciitis sir?? i want it to heal properly and quickly tnx in advance sir GOD bless =)

  • Hi, I just came to this fantastic website…. I started running november 2012 and I have lost 33 pounds while running…. Basically if we want to loss weight we just have to burn more calories and eat less…. when started just could ran 2 miles at the most… now I run 7miles everyday easily…. thanks for the great tips. If I just had found this website sooner I could have known about the right shoes and everything I had to learn the bad way… :/

    Keep up with the great work!!

  • Not a good article. Calories is all that counts?

  • I am new to this. I’m 5’5″ ~ weight fluctuates 130 to 134. I want to get to at least 125lbs. Problem is I find it hard to diet. I like my sweets. I have been going to the gym, started walking on treadmill @4.4speed, work up to a walk /run 6.3speed, for the past 2 week I have gotten in 4 miles a day in 48min. Would like to go longer & faster, but feet/shins start to hurt .Any suggestions on what shoes to wear.??

  • I run 3-4 miles each day 3 days a week. I do elliptical for 2o mins at 90rpm per min. I do weight training 3 times a week. I neither lose nor gain weight. I m 5’7 and 163 lbs male. I feel fit, but can’t reduce weight. Of course I m gaining muscle. I m a veggie and that makes it even harder. I watch my food too. But all I have gained s extra calf muscle, biceps and triceps. Need help to get that magic body
