Fitness IQ: Does Exercise Help You Lose Weight? – Mishpacha Magazine
The latest research shows exercise has little to no effect on the rate of your metabolism

IT

seems straightforward — if you want to boost your metabolism and lose weight, burn calories by moving and exercising more. But the latest research shows exercise has little to no effect on the rate of your metabolism.

Dr. Herman Pontzer, an anthropologist at Duke University, is an expert on human metabolism and energy expenditure. Through his research, he discovered that the average daily expenditure — the amount of calories we burn per day — is the same for everyone, regardless of how much you move.  This means the office worker and the personal trainer both burn the same amount of calories a day, and the amount of time one spends being active has very little to do with the speed of metabolism. Not only is the rate of metabolism the same from person to person regardless of gender, it also remains steady for most of a person’s life. The biggest metabolism drop is at your first birthday, followed by a drop in your twenties. There is a drop again when you hit 60, accompanied by an overall slowdown throughout the body.

Dr. Pontzer’s studies included a wide range of subjects — a modern-day tribe in Tanzania, marathon runners who raced across the US, and people who are sedentary. Study after study showed that active people and sedentary people use the same amount of calories per day.

Before beginning his research, Dr. Pontzer assumed exercise pushes your body into to a calorie deficit, forcing it to burn more calories than you put in. That’s why he chose to study the Tanzanian hunter-gatherers. He assumed that because of the enormous energy they put into their daily activities, they’d be burning thousands of calories a day. However, the research showed otherwise.

The results of his research counter much of what we think about exercise and weight loss. It may also generate questions among those who’ve seen weight loss results after beginning a new fitness routine.

Initially, when you change the intensity of your workout, you may see a change in your weight. But over time, your body makes adjustments to reduce what you burn. For example, say you start a weekly routine where your daily workout burns 500 calories a day. Logically, what would follow is a burn of an extra 3,500 calories per week, resulting in a loss of a pound per week. Instead, what happens is that your body notices the change, and then adjusts to prevent the loss of so many calories. Over time, you’ll notice diminishing returns as your body returns to the baseline metabolic rate.

This is what Dr. Pontzer observed among the marathon runners. The runners ran 26 miles a day from Los Angeles to Washington, DC, over five months. He measured their metabolic levels at three points: prior to beginning the five-month race, a week into the race, and then at the end of the race, a week or two before they reached their final destination. The metabolic rate during the first week of racing rose from pre-race levels as expected. The runners were burning an average of an extra 2,600 calories per day — think 100 calories per mile. But five months later it was below what you’d expect. The runners were burning only an extra 600 calories per day after running 26 miles.

When you think about it, burning an extra 600 calories a day is pretty impressive. But considering the input needed to burn those calories — running a marathon a day — the results are negligible. Also, notice how the bodies of the runners made adjustments so that the initial loss dwindled by 2,000 calories per day.

According to Dr. Pontzer, only the reduction of caloric intake will result in weight loss.

While exercise can’t make you lose weight, it can help control weight in other ways.

A recent study suggested that some exercise could suppress appetite. Researchers focused on ghrelin levels of both men and women before and after exercise. Ghrelin, also known as the hunger hormone, is associated with feelings of hunger. Researchers found that high intensity exercise suppressed ghrelin levels.

Exercise also protects against cardiovascular disease, diabetes, inflammation, and dementia. It’s a mood booster, and has been linked to longevity. So even though exercise won’t kick those extra pounds, it has multiple benefits that make it worth your while.

How to get started at the gym – and keep going

It’s important to have goals in mind as you set out on your fitness journey, whether you’re trying to lose weight, gain muscle or train for a race.skynesher/Supplied

January is notoriously the busiest time of year at the gym. A survey from Ipsos reported that a third of Canadians made exercise-based resolutions for the new year, with many folks working out for the first time or returning to fitness after some time away. If you’re new to exercise, the gym can feel like an intimidating place. But it doesn’t need to be. Below we’ve put together a few suggestions to help you get started.

Have a plan going in

For success at the gym, it’s crucial to have a plan. Before you start, it’s important to identify your goals. Are you looking to get stronger? Training for a race or competition? Do you want to improve body composition? While almost any consistent exercise is going to improve your overall health, specific results require specific training.

Following a workout program can help you stay committed – here’s how to write your own

Those completely new to working out may want to invest in a few sessions with a personal trainer. A reputable trainer will be able to put together a plan based on your preferences and skill level, while walking you through the proper form for each exercise. If cost is an issue, many gyms offer a free intro training session as a sign-up perk. There are also hundreds of different workout programs you can find online and video tutorials outlining proper form.

If you’re intimidated to exercise on your own, a fitness class allows you to follow along with an instructor while getting some quick pointers on how to properly perform the workout. Many gyms offer discounted or free classes to first-time visitors.

Trying to do too much, too fast will burn you out, leave you injured or both

When you’re motivated by a new year’s resolution, it’s tempting to pencil in long gym sessions multiple times a week. But that kind of regime is rarely sustainable. If you’d like to make exercising a habit beyond January – and you’ll need to for any kind of lasting results – it’s best to think about what you can do in the long term.

“You can either do an hour of weightlifting a few days a week, and actually do it, or you have these imaginary 10-hour training sessions you’ll never actually have time for,” said Dan John, strength coach and author. “I try to focus on [programs that are] doable, repeatable and reasonable.”

Similarly, trying to immediately push beyond your physical limitations is a great way to get injured. For weightlifting, it’s important to consider proper warm-ups, active mobility exercises and learning the right techniques before trying to lift anything too heavy. For cardio, Canada Running Series offers a Couch to 5K plan that eases newcomers into jogging by starting small and gradually increasing the length/difficulty of each run.

Follow basic gym etiquette

The gym is a shared public space. Everyone there is trying to get in a good workout. That’s harder to do when people are having phone conversations, listening to videos without using headphones and refusing to wipe down their equipment after use.

In March, fitness trainer Paul Landini wrote an article explaining some unofficial rules to follow when going to the gym, including being mindful of other people’s space and making sure you’re not monopolizing equipment during busy hours.

Try to find what you like about the gym

Changes in body composition, strength and overall health take time. They also need upkeep over the long term. Building a consistent fitness habit is something that will help with all those goals. One of the best ways to do that is finding something at the gym you genuinely enjoy doing. That can be working out with a friend to add a social aspect to exercise and accountability to show up. It can entail learning a new fitness-adjacent skill such as boxing or training for a competition like Hyrox. It can be rooted in the sense of accomplishment that comes with getting stronger. Whatever the reason, finding the joy in exercise is going to be key if you want to move beyond short-term motivation.
