Using a fitness watch or wearable fitness tracker may help some people lose weight when combined with a healthy diet and regular exercise. Fitness watches allow the wearer to track daily statistics such as his number of steps taken, calories consumed and sleep habits.
Tracking the number of calories consumed each day helps a person understand how much and what types of foods he should eat to reach his goal weight. Tracking calories and foods using a fitness watch makes it easier to monitor and limit food intake.
Fitness watches that track the number of steps taken each day and the number of calories burned can help the wearer set daily goals for calorie intake and ensure that the number of calories burned is greater than the number consumed.
