Walking might be pedestrian, but it does a lot for you. So if you're doing the most pedestrian of things, putting one foot in front of the other and just walking—not jogging, not running—are you burning fat? Short answer is yes, walking for exercise burns fat.
Fat Stores
Fat, and not carbs, becomes your main source of energy when walking or exercising at a moderate pace. If you are trying to lose weight, walking can help you burn some of your extra fat.
Carbohydrates contain 4 calories per gram, whereas body fat contains 9 calories per gram. When you walk, your body burns calories regardless of whether they come from carbohydrates or body fat.
Cut Fat: "For losing weight and reducing body fat, it's better to restrict fat intake than to restrict carbohydrates," says Tanya Zuckerbrot, author of The F-Factor Diet. "Restricting either can help you lose weight, especially if by doing so you are cutting overall calories.
One of the most effective ways to reduce belly fat is to regularly take part in aerobic exercise, such as walking ( 19 , 20 ). In one small study, women with obesity who walked for 50–70 minutes three times per week for 12 weeks, on average, reduced their waist circumference and their body fat.
In a new study, which looks at activity tracker data from 78,500 people, walking at a brisk pace for about 30 minutes a day led to a reduced risk of heart disease, cancer, dementia and death, compared with walking a similar number of steps but at a slower pace.
Physical activity, such as walking, is important for weight control because it helps you burn calories. If you add 30 minutes of brisk walking to your daily routine, you could burn about 150 more calories a day. Of course, the more you walk and the quicker your pace, the more calories you'll burn.
The first place men typically lose weight is the belly, while women tend to lose weight all over, but hold onto weight in their thighs and hips, Dr. Block explains.
While you can't spot-reduce fat, walking can help reduce overall fat (including belly fat), which, despite being one of the most dangerous types of fat, is also one of the easiest to lose. The key, though, is staying consistent and walking in the right heart rate zone to maximize calorie and fat burn.
In any given workout, you're burning a combination of fat and carbs. It takes longer to convert fat into energy than it does carbs. Carbs only have 4 calories worth of energy per gram, whereas fat has 9 calories per gram. As you run out of energy from carbs, you start utilizing fat reserves.
Studies show walking is one of the best ways to shed belly fat, in less time than you think. Researchers reviewed 40 years of studies on exercise and belly fat and found that just 2 1/2 hours of brisk walking a week--about 20 minutes a day--can shrink your belly by about 1 inch in 4 weeks.
Depending on your weight, you can burn 100-200 calories with 30 minutes of brisk walking. You can burn anywhere between 500-1000 calories per week by doing this at least 5 days a week. If you want to burn more calories while walking, aim for more than 30 minutes.
High-intensity interval training (HIIT): It is probably one of the fastest and most efficient ways to lose stomach fat and reduce the overall body fat percentage. HIIT is a high-intensity short period of exercise that usually doesn't exceed 30 minutes, with short breaks of recovery periods of 30-60 seconds.
Sugar and refined carbs are the main culprits here. So, if you want to decrease the amount of fat your body stores, you'll need to reduce or avoid sugars and refined carbs and replace them with vegetables, fruits, and whole grains.
Reducing your carb intake can be very beneficial for losing fat, including abdominal fat. Diets with under 50 grams of carbs per day cause belly fat loss in people who are overweight, those at risk for type 2 diabetes, and women with polycystic ovary syndrome (PCOS) ( 31 , 32 , 33 ).
We've all heard the term 'fat-burning', but how does it really happen in the body? Fat cells in the body release a hormone that signals to the brain that there is enough energy stored. This triggers your body to burn energy stored as fat.
In addition to an oily appearance, your urine might also have a milky white color. This is due to the presence of fat and protein in lymph fluid.
The first stage of weight loss is when you tend to lose the most weight and begin to notice changes in your appearance and how your clothes fit. It usually happens within the first 4–6 weeks ( 1 ). Most of the weight loss in this stage comes from carb stores, protein, and water — and to a lesser extent, body fat.
Average walking speed by age:
20-29 years: 3.00 mph (4.83 km/h) 30-39 years: 2.82 mph (4.54 km/h) 40-49 years: 2.82 mph (4.54 km/h) 50-59 years: 2.75 mph (4.43 km/h)
Walking is a form of low impact, moderate intensity exercise that has a range of health benefits and few risks. As a result, the CDC recommend that most adults aim for 10,000 steps per day . For most people, this is the equivalent of about 8 kilometers, or 5 miles.
You might start with five minutes a day the first week, and then increase your time by five minutes each week until you reach at least 30 minutes. For even more health benefits, aim for at least 60 minutes of physical activity most days of the week.
