This may be why the 80/20 rule has become popular, stating that weight loss is the result of 80% diet and 20% exercise. For example, if you’re aiming for a 500-calorie deficit per day, you can cut 400 calories (80%) by eating lower-calorie meals, smaller portions, and snacks.

There are many ways exercise can support weight loss. Strength training helps maintain and build muscle mass. This increases your metabolism over time, allowing your body to burn more calories even at rest. Plus, a single strength training session can boost your metabolic rate for up to 72 hours. Aerobic exercise, such as walking, jogging, and cycling, can burn a significant number of calories per session and contribute to calorie deficit, especially if done at low to moderate intensity for 30 minutes or more.
