To lose fat, you need to burn more calories in a day than you eat (also known as creating a caloric deficit) — and you have to do this over and over again. If you do this long enough, your body will use existing fat stores for energy.
The result?
Fat-loss!
You can create a caloric deficit by making dietary changes, but exercise can also help. In fact, exercise may even amplify your results: In one study, overweight and obese women who followed a diet and exercise program for one year lost more weight than women who followed a diet-only program (10.8% versus 8.5%).
If you’re thinking of adding exercise to your fat-loss plan, you might consider starting with the easiest option: brisk walking. A 15-year study published in the 2009 issue of The American Journal of Clinical Nutrition found walking was associated with less weight gain over time. In other words, walking regularly may help you maintain — or even lose — weight over the long term.
Regular cardio exercise like walking can also lower levels of abdominal and organ fat, which play a key role in the development of chronic diseases like diabetes, high blood pressure and obesity, even though you may not see a change on the scales. A 2015 study in the Journal of Hepatology, for example, found regular aerobic exercise improved liver fat by 18–29% in overweight and obese people — regardless of exercise intensity.
TRY BRISK WALKING
Thankfully, walking is a pretty straightforward activity. This fundamental form of locomotion is a great way to burn those extra calories, among many other health benefits. It can be done in almost any environment and with minimal equipment. And when I say brisk, I mean BRISK. Walking at a BRISK pace as opposed to a casual pace.
Walking at any pace does offer benefits, but walking at a brisk pace may offer even further fat-loss benefits. Consider these estimates from Harvard Medical School: A 70-kilogram person who walks for 30 minutes at a pace of 5.5 km/hr burns roughly 149 calories, but if that same person bumps up the pace to 6.5 km/hr, he/she burns roughly 167 calories in 30 minutes.
So, what qualifies as “brisk walking”? According to the Centers for Disease Control and Prevention (CDC), walking at a pace of at least 4 km/hr is considered brisk walking, and falls under the category of moderate-intensity exercise.
However, walking at a pace of 4 km/hr will feel more or less intense depending on your height, weight, fitness level, as well as the terrain (i.e., hilly or uneven terrain makes your walk feel more intense than flat or even terrain), it might be better to gauge your intensity on a scale of 0–10. On this scale, 0 corresponds to sitting, while 10 corresponds to the highest level of effort possible. According to the CDC, moderate-intensity activities — like brisk walking — should feel like a 5 or 6.
If you’re not sure where to start, try following these recommendations from the CDC: Aim to get at least two-and-a-half hours of moderate-intensity cardio (i.e., brisk walking) every week. For even greater health benefits (e.g., reduced risk of heart disease, Type 2 diabetes and fat gain), double these recommendations.
Be sure to pair your walking routine with a healthy eating habit. Whilst exercise can help you create a caloric deficit — through the calories burned both during and after the workout — your healthy eating habit is critical. One of the keys for fat loss is how much energy you expend with each exercise session, and how many calories you’re consuming via what you are eating.
If you’re new to exercise or have special considerations, it is recommended to get help from a fitness professional, such as a Personal Trainer.
OTHER REASONS TO WALK
Fat loss is only one reason to add walking to your routine. Exercise is one of the most important things you can do for good health.
For one thing, regular exercise like brisk walking can improve your cardiorespiratory fitness. Cardiorespiratory fitness is important for health and longevity that leading physicians have called for it to be measured in routine check-ups as a vital sign of overall health.
According to a statement from the American Heart Association, having low cardiorespiratory fitness is associated with a high risk of heart disease, death from any cause and death from various cancers. What’s more, even small improvements in cardiorespiratory fitness can lead to considerably lower rates (10–30%) of heart attacks, strokes and other adverse cardiovascular events.
Research in The Primary Care Companion also reveals cardio exercise like walking can reduce anxiety and depression and improve self-esteem and mental function.
