Fitness: Is exercise still considered important for weight loss?
Carrying too much weight increases the risk of heart disease, high blood pressure, stroke, type 2 diabetes, some cancers and breathing problems.
Article content
The American College of Sports Medicine recently published a consensus statement summarizing the latest research on physical activity and excess body weight. Exercise has long been recommended as part of treatment plan designed to lose unwanted pounds, but does science still support the notion exercise is an important component in weight loss?
Societal standards of what constitutes an ideal weight aside, most health-care professionals advocate weight loss based on its effect on health, not how you look in a pair of jeans. Carrying too much weight increases the risk of heart disease, high blood pressure, stroke, type 2 diabetes, some cancers and breathing problems.

Yet the difficulty in prescribing exercise as a weight-loss tool is not only does it take a lot of exercise to affect weight, but individuals carrying excess pounds are less likely to start an exercise program and if they do, they are also more likely to drop out.
Another issue is weight-loss success from exercise alone isn’t guaranteed, even if the same group of people follow the same exercise routine. And while there’s some evidence suggesting it takes a minimum of 150 minutes per week of moderate to vigorous intensity exercise to move the numbers on the scale, there’s no consensus among experts it’s enough, especially given the variability of the results in study subjects.
Even then weight loss is modest if there’s no concurrent reduction in the daily number of calories consumed. According to the ACSM, one can expect a modest weight loss of only 0.5-3 kg when using exercise as the sole strategy to lose weight. It’s only when diet and exercise are combined the results become more significant.
“When combined with an energy-restricted diet, the effect of physical activity on body weight and adiposity is additive to diet and enhances weight loss by approximately 20 per cent, compared to what is observed with an energy-restricted diet alone,” said the authors of the ACSM’s latest consensus statement.

As to what kind of exercise is most effective at losing unwanted weight, there is little evidence suggesting one form of physical activity is better than the other. But if you want the most bang for your buck in the gym, it’s clear intensity matters. Moderate to vigorous intensity workouts will burn calories at a greater rate than light intensity activities, so keep that in mind if finding time to exercise is an issue.
The same goes for diet. There’s no evidence suggesting one diet is more effective than the other when it comes to creating a successful weight-loss routine, including time-restricted eating and intermittent fasting. The most important thing is to consume fewer calories, how you do it seems to make little difference in the long run.
“At the population level, one type of diet and macronutrient composition does not appear to be more effective for weight loss when compared to other approaches, provided these approaches result in similar effects in achieving negative energy balance,” stated the ASCM in its consensus statement.
In addition to clearing up any confusion as to whether one diet and exercise combination is more effective than another, the ACSM also addressed the idea eating at a certain time of day may be more advantageous for weight loss. Based on the theory exercise blunts appetite and eating fewer calories in the morning results in a greater negative energy balance than eating fewer calories at night, there’s little evidence restricting eating and exercise to certain times of day is an effective weight-loss strategy.

Also, worthy of mention by the ACSM is except for intense exercise (greater than 70 per cent of maximum effort), physical activity has little effect on appetite. Any suppression of hunger post-exercise is short-lived and doesn’t have an effect on the number of calories consumed daily, so don’t count on exercise to make that trip to the cookie jar seem less appealing.
What does aid diet and exercise in whittling down body weight is the use of smart watches/wearables and apps. Not surprisingly, the ability to set daily activity and energy expenditure goals, track physical activity and diet and get real time feedback on lifestyle habits as well as reminders to get moving has proved to enhance weight loss.
“In 73 per cent of instances, greater monitoring of physical activity behaviour was linked to greater weight losses,” stated the ACSM consensus statement. “This suggests that for those with overweight and obesity, the self-regulatory process of monitoring raises awareness of physical activity and diet behaviour and enables a feedback loop of gathering and receiving personal data to make progress toward weight-related goals.”

This latest update on the role of exercise in weight loss hasn’t shaken the ACSM’s belief it’s still a valuable weight-loss tool, including for those taking anti-obesity medications. Diet and exercise still move the numbers on the scale. It’s also a reminder the benefits of exercise go beyond cinching your belt a little tighter. Improved health, vitality, sleep and mood and more muscle mass are just some of the advantages of regular exercise, even for those who struggle to reach their weight-loss goals. It takes as little as a five per cent decrease in body weight to start accruing health benefits, so every workout offers a reward — even if it can’t be seen.
“ACSM advocates for physical activity to be a key element of prevention and treatment efforts for exercise body weight and adiposity, with a focus on implementation of inclusive approaches to facilitate adoption and sustained engagement of physical activity of all persons,” stated the ACSM in their consensus statement.

From Lifespan to ‘Health-span’: Use the New Year to Focus on Both Health and Fitness
Fitness encompasses cardiovascular endurance, strength training, and mobility/flexibility. These are non-negotiables for continuing to live throughout your later years with your independence and ability to move and socialize still intact.
Instead of thinking simply about living longer, let’s use the start of a new year to focus on getting healthier, so we live better. More than any other time each year, the New Year is a popular time to focus on a “fresh start.” Temporal landmarks like New Year’s Day, Mondays, birthdays and the change of seasons are standard starting lines for many of us when we have a goal to work toward and bad habits to break.
Science Says Fitness Matters (Even More than Weight)
A recent study published in the British Journal of Medicine, Cardiorespiratory Fitness, BMI, and Mortality: A Systematic Review and Meta-Analysis, shows that, regardless of body weight (obese, overweight or normal), fitness matters more for all-cause mortality. They measured the weight, BMI and fitness of six groups: normal weight-fit; normal weight-unfit; overweight-fit; overweight-unfit; obese-fit; and obese-unfit.
The analyses revealed that individuals classified as fit, regardless of their BMI, did not have a statistically significantly higher risk of cardiovascular disease or all-cause mortality compared to normal weight-fit people. At the same time, all unfit groups across different BMI categories exhibited a two- to threefold higher risk of cardiovascular disease and all-cause mortality compared to their regular weight-fit counterparts.
About Body Mass Index (BMI)
Now, you may be saying, “But BMI is flawed!” Sure. BMI is not the best indicator for distinguishing normal weight, overweight and obesity because it is simply a height-to-weight ratio that does not account for differences in body fat/muscle composition, age, sex or other factors. Before you discredit this entire study because of the BMI issue, remember that it measured fitness levels among people of different sizes. Some had more muscle and were considered fit in the overweight/obese group, while others were deemed unfit in the normal weight group. Still, BMI helps place people of differing sizes (height and weight groups) and focuses on measuring each group’s fitness. In the end, fitness matters more than BMI, so the goal is to exercise, get in shape, build muscle and lose fat.
Set Your Training Goals to Be Long-Term
It is fine to have short-term, specific training goals, such as strength gains and endurance times, or weight gain or weight loss. However, start this year with a 10-year fitness focus, as what you do in your 40s-50s will determine how you live in your 60s-70s. Always think 10 years ahead, no matter what your age, because what you gain today and maintain tomorrow is needed to continue to live independently for a few more generations in your family’s lineage. You can focus on longevity and optimal performance for your fitness and health goals at the same time by maintaining a consistent activity level and healthful nutrition, sleep and recovery.
Try This Goal: Make Annual Physical and Blood Screening Appointments
If you have not been to a doctor in a while, set an appointment in January, and get into the habit of annual health and wellness screenings. Treat annual physicals with the doctor as opportunities to PR (personal record) common blood work results, such as cholesterol, triglycerides, blood sugar, body weight and blood pressure. These are just the basics to help you assess how to adjust your sleep, nutrition, physical activity and stress management. These meetings are also quite satisfying when you achieve solid results that show health and wellness.
Don’t Give Up
While a large portion of us (nearly half of Americans) will create a New Year’s resolution, only about 9%-10% will achieve their goals. After a stressful holiday season, we are typically burned out in January. This may not be the best time to start a lifestyle change, complete with quitting bad habits (over-eating, smoking, drinking) and starting new healthy habits (gym membership, diet, etc.).
Instead, use the first few weeks of January to focus on stress mitigation and recovery. This should include building easy habits of walking every day, stretching, taking deep breaths and simply not overeating. This is a great way to move into a new fitness focus. Then, when feeling back to normal, focus a little harder, with more intensity, duration of training, and specificity to your fitness and health goals.
There are many ways to expand your “health-span.” Check out these options and get consistent with any or all of them:
Final Advice
If you want to get started on a focused health and wellness goal of being able to do physical activities, stay social and be independent, start with the basics of walking and stretching daily for a month. The following month, add calisthenics such as squats, lunges, push-ups and the plank pose. The following month, add weights such as dumbbells or kettlebells, or suspension trainers such as the TRX.
This steady progression helps you ease into fitness habits gently and adds a new component each month to keep it interesting. To achieve results with lifelong wellness goals, you need to keep endurance, strength and mobility/flexibility as primary focuses. Stability, durability, balance, speed and agility can also be developed once you have built the foundation. This is the beauty of long-term goals. Focus on doing something each day, being disciplined about eating and drinking healthfully, and learning stress-mitigation techniques such as breathing to take into your next decade on this planet.

Exercise ‘snacks’ can keep your fitness on track when time is tight – try these 3 today
December is great for many things – socialising, scoffing, falling out with relatives – but sticking to a training schedule is not one of them.
Heading out the door on Christmas morning for a two-hour long run is likely to put anyone on the naughty list, while it takes a dedicated runner indeed to spend part of the festive period running loops of the track.
What the mere mortal needs is exercise “snacks”. These can be enjoyed/endured alongside the carb-based variety and snuck in to even the busiest Christmas schedule.
A review in Sports Medicine and Health Research confirmed that regular, short bursts of physical activity throughout the day improved cardiovascular respiratory fitness, increased fat oxidation and polished off blood sugar levels after eating.
Vigorous intermittent exercises, such as sprints, were good for building muscle strength. Meanwhile, 10-minute resistance training sessions were found to be particularly beneficial to older people. The researchers concluded that exercise snacks could be a viable alternative to longer, less frequent sessions.
Cram in vigorous bouts of stair climbing for muscle strength, or one or two sub-10 minute morsels for muscle growth as an efficient alternative to meatier long sessions. Here’s some inspo below…

Study shows the antioxidants in this tea improve exercise recovery
I love many different herbal teas just as much as I enjoy a good old-fashioned British cup of PG tips, Earl Grey, or Glengettie — a Welsh favorite from the rolling valleys where I was born. In an interesting study, researchers explored whether drinking green or matcha tea can improve sports performance and exercise recovery, and the results might have you reaching for a vibrant green drink. If you want to get straight to the results, the short answer is that drinking green and matcha tea can support hydration, body fat control, and exercise recovery. Still, it definitely won’t be a game-changer when it comes to your performance in the gym, on the court, or on the field.
Hydrating with tea
In a study published in Nutrition and Food Technology, researchers reviewed existing studies of athletes and active adults that focused solely on drinking tea — no pills or extracts. They revealed that green or matcha tea can help hydrate the body when consumed in normal amounts. Tea counts toward your daily water intake.
Antioxidants and recovery

The research highlighted how the widely-studied antioxidants in green and matcha tea can improve exercise recovery and help protect your cells from the stress associated with intense exercise. That said, the research shows that drinking tea won’t lead to faster or better strength gains, so it’s no silver bullet for helping you achieve your fitness goals. However, they also concluded that low-caffeine green tea could even improve sleep quality, which I would argue could potentially help you power through that workout if you’re getting better sleep the night before.
Linked to lower body fat

Interestingly, the study authors also concluded that drinking around two or three cups of green or matcha tea per day was associated with slightly lower body fat and improved body composition and fat burning. While the effects weren’t overly significant, they were noted in the research. Cup of tea, anyone?
