How accurate is this swimming calorie calculator?

This calculator provides reasonable estimates based on established MET values for swimming. Actual calorie burn varies based on swimming technique, water temperature, and individual factors. Swimmers with efficient technique may burn slightly fewer calories at the same pace than beginners.

Which swimming stroke burns the most calories?

The butterfly stroke burns the most calories—up to 150% more than leisurely swimming—because it requires coordinated power from your entire body. Freestyle at a vigorous pace is second, followed by backstroke and breaststroke. However, most people can't sustain butterfly for long.

Is swimming good for weight loss?

Swimming is excellent for weight loss. A moderate 30-minute swim can burn 200-350 calories depending on your weight and intensity. It's low-impact, sustainable, and works your entire body. Many people find they can swim longer than they can run, leading to higher total calorie burn.

Why do I feel so hungry after swimming?

Swimming often increases appetite more than land-based exercise due to several factors: cold water exposure increases calorie burn and hunger signals, the horizontal position affects hunger hormones differently, and swimming uses many muscle groups. Be mindful of portion sizes post-swim if weight loss is your goal.

How does swimming compare to running for calorie burn?

Vigorous swimming burns similar calories to running—sometimes even more. A fast freestyle swim can burn 500-700 calories per hour, comparable to moderate-pace running. Swimming has the advantage of being zero-impact and working upper body muscles that running neglects.

Does treading water burn calories?

Yes, treading water burns significant calories—roughly 200-400 calories per hour depending on intensity and weight. Vigorous treading water approaches the calorie burn of moderate lap swimming because you're constantly working against water resistance to stay afloat.
