How to Keep Patients from Sabotaging Their
Exercise Programs

by Jonathan Cannizzo, MSc

A recent publication in PeerJ documented compelling evidence that exercise might not be the key to controlling body weight. This study found that over a three-year period, total weight gain was greater among participants who met the physical activity guidelines of two and a half hours a week, compared to those who did not.

This leads us to the question: Does exercise lead to weight gain and possibly obesity?

As we dig into this question, I want to be clear that the reason we prescribe exercise is not to lose weight. We prescribe exercise because it prevents disease and is part of a healthy lifestyle.

This publication is one we must all understand, because it helps illustrate the daily challenges every patient goes through with exercise adherence, food choices, weight loss and progress.

When prescribing exercise to your patients, remember this: You are not attempting to get your patients to start exercising; you are attempting to get your patients to change a behavior pattern—and that can be extremely difficult.

Exercise Does Not Equal Physical Activity

Wake up, drive to work, sit at a desk for eight hours, drive home, eat dinner, watch television, go to sleep. Repeat. That’s a day in the life of most Americans and, as you can see, a lot of time is spent being sedentary. Even if we squeeze in 30 minutes of moderate exercise, it still doesn’t change the negative effects of sitting for long stretches. This lifestyle pattern led researchers to coin the phrase “Sitting is the New Smoking” because they documented that having a sedentary lifestyle is as predictive of cardiovascular disease as smoking. 1

We Are All Cheaters

As a former dietician and exercise physiologist, lifestyle medicine is my life. I pride myself on the fact that I exercise daily and eat a whole-food, plant-based diet, but, last week after lunch, we were celebrating a colleague’s birthday with cookies. Naturally, I picked up a cookie and ate it. My internal justification was, “It’s OK to eat this cookie, I got in a great workout this morning.” How familiar does that sound? Sure, long-term it’s only one cookie, and I am usually very diligent with my lifestyle choices. But for most patients who haven’t been so diligent, that cookie is a big deal and it will affect them long-term. In fact, researchers found that given the ability to choose the amount of food you eat, people ate more after an exercise session (and even more if the exercise session was intense) than people who did not exercise. 2

The Truth Will Set You Free

One thing I will always remember from my time as a clinician was just how much patients exaggerated their diet and exercise programs. During consults, I’d frequently hear something like, “Yes, I exercise every day and I eat a huge salad with salmon for lunch” from just about every patient. But when I’d examine their food and exercise logs, they would tell a significantly different (i.e., worse) story. The truth is, self-perception of compliance to a lifestyle-based program often does not line up with reality. To illustrate that, a group of researchers looked at self-reported frequency of exercise. They found that males and females exaggerate their exercise frequency by 44% and 138%, respectfully. 3

So, what do we do about this?

It’s important to remember the greatest challenges for patients is to change the behavior patterns surrounding the simple choices they make each day. Knowing this, we must stress the following tips:

1. Don't be an exercise couch potato!

Challenge patients to set a cell phone alarm to go off every 45 minutes to remind them to get up and take a walk. Even if that walk is to the water cooler and back, it still counts!

2. Don’t fill your Ferrari with orange juice.

The body is an engine and needs to be fed properly. Remind patients that exercise is not a reward to cheat on your diet.

3. Journal every day.

For at least the first 30 days of a program, encourage patients to keep a daily diet and exercise log. This will give them an idea of the challenges they face each day, as well as help them find ways to improve compliance.

To answer our original question, no, exercise does not lead to weight gain and obesity, but exercise is also not the only determining factor in weight loss. Continue to remind your patients that the goal of exercise is not to lose weight. The goal of exercise is to be healthy and prevent disease!
