The Study Breakdown · No. 1

We are starting a series where we take a study that caught our attention, break down what it actually shows, challenge anything that does not add up, and pull out what you can use straight away. First up, one that quietly changes how you should think about your daily walk.

Each time, we will be asking:

01What does the study show us?
02What are the limitations?
03What questions are we left with afterwards?
04What can we learn, and what can we apply in daily life?

This study was referenced in an excellent book, Longevity Simplified by Howard Luks MD, an orthopedic surgeon, sports-medicine specialist and endurance athlete. Over the course of the book he outlines a simple framework for optimal health.

Luks’ framework for optimal health
Create a caloric deficit, then stay lean
Move often, throughout the day
Get sleep
Push and pull heavy things
Eat real food
Socialise
Have a sense of purpose

If you have trained with us at ATP, you will know he is preaching to the choir. We are advocates for keeping things simple and executing on a daily basis. One of the studies he referred to really jumped out at us. The title was:

“Is it fun or exercise? The framing of physical activity biases subsequent snacking.”

The framing trap

It turns out that how we perceive activity is vitally important. If we are pursuing a weight-loss goal, the wrong framing can quietly sabotage our efforts.

If we treat physical activity as an imposition, we create a debt that needs paying off. We then square off our accounts with the requisite amount of reward.

Framed as exercise
Feels like work
Creates a debt to repay
The brain hunts for a reward
You snack more
Framed as fun
Enjoyable in itself
No debt is created
You just reap the benefits
You keep the win
“Engaging in a physical activity seems to trigger the search for reward when individuals perceive it as exercise, but not when they perceive it as fun.”

If we frame physical activity in terms of the enjoyment we get from it, in this case a scenic walk, then no such accounting is triggered and we are free to reap the benefits. There were three studies. Two with more of a general-population sample, and one with a more athletic group.

The three studies at a glance

Study 1

56 women were split into two groups. The first was told the 30-minute walk was exercise. The second was told it was recreational, and that they were testing music on an MP3 player. Afterwards they were taken to a buffet where the amount they ate was measured. Both groups had one main course, a fairly healthy pasta bolognese with vegetables and bread, then two choices each for drink and dessert:

Indulgent (hedonic)
Coke · Chocolate pudding
Sensible (utilitarian)
Bottled water · Applesauce

Both groups ate the same amount of the main course. But the group told they were exercising took in significantly more calories from the dessert and the drink.

EnergyMore tired, lower energyMore energy, less tired
The walkLess excitingMore exciting
MoodLess positiveMore positive
“When an effortful activity is perceived as exercise, it leads to increased consumption of hedonic foods (but not of utilitarian foods) compared with when the same activity is perceived as fun.”

A limitation. While directionally accurate, there are issues with the data. The total calories consumed are spectacularly low, which makes us think there was an error somewhere in the methodology or the formulas. As you can see below, the totals stay very low regardless of the choice.

*Regular meal was pasta with beef, green beans and bread. The only significant differences were in the hedonic dessert and drink, and the chocolate pudding, where the exercise group ate more.

Study 2

Same design, but they dropped the music cover story and simply framed the walk as scenic. They also skipped the sensible lunch and went straight to an unhealthy snack: M&Ms.

M&Ms eaten after the walk
Framed as exercise
374 cal
Framed as fun / scenic
166 cal
The “exercise” group ate 2.25× more than the “fun” group after the identical walk.

Study 3

The first two studies used a sedentary, non-athletic population, so it is interesting that the third supports the same central idea with athletes.

“Participants who had more fun during the race were more inclined to choose the cereal bar than participants who had less fun.”

There was a relationship between how much fun people had during a race and their snack choice afterwards. Neither snack is truly “healthy,” but chocolate bar versus cereal bar fits the general public’s view of an indulgent versus a virtuous choice.

Concluding thoughts

“Consumers who are contemplating beginning a physical activity routine in order to help lose weight would be well advised to make certain they reframe it so they see it as fun, or at least not as work or exercise. Listening to music during a run, making phone calls during a walk, or watching a video during a treadmill routine may be more related to weight-loss success and perseverance than previously thought.”

In other words, a podcast or music might make steady-state cardio far more enjoyable.

For us this reaffirms some long-held suspicions about how we operate: how our bodies and minds seek balance and equilibrium despite our best efforts. For coaches and clients, it means we should not suffer and sacrifice too much early on, or we stack up a debt that may need repaying later.

What to actually do with this
1The best form of exercise really is the one you enjoy.
2Find activities with intrinsic enjoyment, like a good walk.
3There is a reason our D.N.A. is Daily Routine, Nutrition, Activity, not Exercise. Activity is not always formal exercise.
4You will enjoy a lot of these activities far more once you have a base level of fitness and strength.
5Short-term sacrifices can sharpen fitness and body composition, but re-integrate into a lifestyle that is enjoyable rather than onerous.
6Fun is energising. We need fewer calories when we feel alive after activity we enjoy.
7Pair exercise with a non-food reward. A show, a podcast, or a scheduled call with a good friend.
8There are many ways to get healthier that do not hinge on sacrifice and deprivation. That is almost always the better path for a lifetime.
