Calories Burned in an Hour of Exercise for Weight Loss
Introduction
Exercise is a cornerstone of any weight loss journey. By engaging in physical activity, you increase the number of calories your body burns, creating a calorie deficit when combined with proper nutrition. A calorie deficit—burning more calories than you consume—is the foundation of weight loss. But not all exercises burn calories at the same rate. High-intensity cardio might torch calories quickly, while strength training offers long-term benefits by building muscle. In this article, we’ll explore how different exercises contribute to weight loss by estimating the calories burned in one hour. Note that these figures are based on a 155-pound individual, and your actual calorie burn may vary depending on factors like weight, age, gender, and fitness level.
Balancing Nutrition and Exercise for a Healthy Weight
Understanding Calorie Burn
How do we estimate calories burned during exercise? One common method uses Metabolic Equivalents (METs), which measure the energy cost of an activity. One MET is the energy you expend at rest—about 1 calorie per kilogram of body weight per hour. Activities with higher MET values, like running or swimming, burn more calories because they require more effort. The formula to calculate calories burned per minute is:
For simplicity, we’ll use established estimates from reputable sources rather than calculating each one manually. For example, Harvard Health provides data on calories burned in 30 minutes, which we’ve doubled to estimate hourly rates for a 155-pound person. Understanding this helps you see why some exercises burn more calories than others.
Factors Affecting Calorie Burn
Calorie burn isn’t one-size-fits-all. Several factors influence how many calories you burn during exercise:
- Body Weight: Heavier people burn more calories because it takes more energy to move a larger mass.
- Intensity: The harder you work, the more calories you burn. Running at 7.5 mph burns more than walking at 3.5 mph.
- Duration: Longer sessions burn more calories, though high-intensity exercises might limit how long you can sustain them.
- Fitness Level: As you get fitter, your body becomes more efficient, potentially burning fewer calories for the same effort.
- Age and Gender: Metabolic rates decline with age, and men often burn more calories than women due to higher muscle mass.
These variables mean the numbers below are estimates. Your results might differ, but they’re a solid starting point for planning your weight loss workouts.
Cardio Exercises for Calorie Burn
Cardio exercises get your heart pumping and are some of the best ways to burn calories quickly. Here’s a rundown of popular cardio activities and their hourly calorie burn for a 155-pound person.
Running
Running is a classic calorie-burning exercise. The faster you go, the more calories you torch:
- 5 mph (12 min/mile): 480 calories per hour
- 6 mph (10 min/mile): 600 calories per hour
- 7.5 mph (8 min/mile): 750 calories per hour
Running is high-impact, so start at a pace you can maintain. It’s perfect for weight loss because it engages large muscle groups and elevates your heart rate. (Source)
