It is essential to be consistent and not expect significant changes overnight. There is no one size fits all answer for how much cardio exercise a person should do to lose weight. However, tools are available that can create individual activity plans for different people.
Cardio is excellent for weight loss and staying healthy. Combining cardio with other types of exercise has great benefits, such as strength training. Making sure the exercise is enjoyable will help a person maintain the habit. This might involve some trial and error before a person finds the type of exercise that suits them best. Being a healthy weight offers many health benefits, as well as a feeling of wellbeing. Fast weight loss is rarely easy, but it is possible to lose….

A person's fat burning heart rate depends on their age. Staying within this heart rate range during exercise is supposed to help people lose weight…. Swimming can benefit the mind and body in various ways. Here, learn more about the range of health benefits that swimming can offer.
Cardio for weight loss: What to know. Medically reviewed by Daniel Bubnis, M. Department of Health and Human Services recommends getting at least to minutes of moderate-intensity cardio or 75 to minutes of vigorous-intensity cardio per week for substantial change.
Moderate intensity cardio includes a brisk walk that gets you a little sweaty and breathing a little heavier than usual, but you can still talk. Vigorous-intensity cardio makes you breathe fast and hard, making it too hard to talk think a killer HIIT sesh or a run. So, at a bare minimum, you could do a minute brisk walk 5 days a week to get some cardio in. But depending on your body, you might need to spend more time walking or try something more intense. If weight loss is your goal, choosing exercises that burn the most calories in the shortest amount of time will help you make the most out of your workout.
The Center for Disease Control and Prevention says that a pound person doing a minute cardio workout can burn between and calories. Popular cardio activities and the estimated number of calories they can burn in 30 minutes include:. Keep in mind that these are estimates.
The actual number of calories that you burn will depend on your current weight and other factors unique to your body. Do what works for you and your routine. If you hate running with a burning passion, walk or hike.
Combining cardio, strength training, and a healthy diet will put you on a path to weight loss. Starting with just 30 minutes of walking a day can get you going. Then you can build up to adding different types of cardio and strength training at least twice a week.
Or if you really want to challenge yourself, look for fitness classes or activities that combine cardio and strength training in one sweet sweat sesh.

Consider this review of exercise intervention studies, published in It found that after 20 weeks, weight loss was less than expected, and that "the amount of exercise energy expenditure had no correlation with weight loss in these longer studies.
To explore the effects of more exercise on weight, researchers have followed everybody from people training for marathons to sedentary young twins to post-menopausal overweight and obese women who ramp up their physical activity through running, cycling, or personal training sessions.
Most people in these studies typically only lost a few pounds at best, even under highly controlled scenarios where their diets were kept constant. Other meta-analyses, which looked at a bunch of exercise studies, have come to similarly lackluster conclusions about exercise for losing weight. This Cochrane Review of all the best available evidence on exercise for weight loss found that physical activity alone led to only modest reductions.
Ditto for another review published in University of Alabama obesity researcher David Allison sums up the research this way: Adding physical activity has a very modest effect on weight loss — "a lesser effect than you'd mathematically predict," he said. We've long thought of weight loss in simple "calories in, calories out" terms. In a much-cited study, researcher Max Wishnofsky outlined a rule that many organizations — from the Mayo Clinic to Livestrong — still use to predict weight loss: A pound of human fat represents about 3, calories; therefore, cutting calories per day, through diet or physical activity, results in about a pound of weight loss per week.
Similarly, adding calories a day results in a weight gain of about the same. Today, researchers view this rule as overly simplistic. They now think of human energy balance as "a dynamic and adaptable system," as one study describes. When you alter one component — cutting the number of calories you eat in a day to lose weight, doing more exercise than usual — this sets off a cascade of changes in the body that affect how many calories you use up and, in turn, your bodyweight.
One very underappreciated fact about exercise is that even when you work out, those extra calories burned only account for a tiny part of your total energy expenditure. There are three main components to energy expenditure, Kravitz explained: 1 basal metabolic rate, or the energy used for basic functioning when the body is at rest; 2 the energy used to break down food; and 3 the energy used in physical activity. We have very little control over our basal metabolic rate, but it's our biggest energy hog.
Digesting food accounts for about 10 percent. That leaves only 10 to 30 percent for physical activity, of which exercise is only a subset.
You can read more about this concept here and here. Using the National Institutes of Health Body Weight Planner — which gives a more realistic estimation for weight loss than the old 3,calorie rule —the NIH's Kevin Hall created this model to show why adding a regular exercise program is unlikely to lead to significant weight loss. If a hypothetical pound man added 60 minutes of medium-intensity running four days per week while keeping his calorie intake the same, and he did this for 30 days, he'd lose five pounds.
More on these "compensatory mechanisms" later. So if one is overweight or obese, and presumably trying to lose dozens of pounds, it would take an incredible amount of time, will, and effort to make a real impact through exercise. That's why Hall thinks researchers find again and again that exercise can help maintain weight loss, but it doesn't help people lose weight. Exercise can even undermine weight loss in subtle ways.
How much we move is connected to how much we eat. As Hall put it, "I don't think anybody believes calories in and calories out are independent of each other. One study shows that people seemed to increase their food intake after exercise — either because they thought they burned off a lot of calories or because they were hungrier. Another review of studies from found people generally overestimated how much energy exercise burned and ate more when they worked out. A single slice of pizza, for example, could undo the calories burned in an hour's workout.
So could a cafe mocha or an ice cream cone. There's also evidence to suggest that some people simply slow down after a workout, using less energy on their non-gym activities. They might decide to lie down for a rest, fidget less because they're tired, or take the elevator instead of the stairs. These changes are usually called "compensatory behaviors," and they simply refer to adjustments we may unconsciously make after working out to offset the calories burned.
The most intriguing theories about why exercise isn't great for weight loss describe changes in how our bodies regulate energy after exercise. Researchers have discovered a phenomenon called "metabolic compensation. In other words, our bodies may actively fight our efforts to lose weight. For one fascinating study, published in the journal Obesity Research in , researchers subjected seven pairs of young, sedentary identical twins to a day period of intense exercise.
For two hours a day, nearly every day, they'd hit a stationary bike. The twins were also housed as inpatients in a research lab under hour supervision and fed by watchful nutritionists who measured their every calorie to make sure their energy intake remained constant.
