How accurate are the calorie burn calculations and what affects accuracy?

The calculator uses scientifically-established MET (Metabolic Equivalent) values from exercise science research, providing highly accurate estimates for most people. However, individual factors like fitness level, age, gender, body composition, and metabolism can cause 10-20% variations from calculated values. Use calculations as reliable guidelines for planning and comparison rather than exact measurements.

What are MET values and how do they determine calorie burn?

MET (Metabolic Equivalent) values measure exercise intensity compared to resting metabolic rate. 1 MET equals your resting state calorie burn, while 3 METs means you burn 3 times more calories than at rest. The calculator uses the formula: Calories = MET × Weight (kg) × Time (hours). Higher MET values indicate more intense activities that burn calories faster.

Can I use this calculator for weight loss planning and calorie deficit creation?

Absolutely! The calculator is excellent for weight loss planning. Use it to calculate calorie deficits from exercise, compare different activities for efficiency, and track daily calorie burn. Remember that creating sustainable calorie deficits of 500-1000 calories per day (through diet and exercise combined) typically leads to healthy weight loss of 1-2 pounds per week.

How do intensity levels affect calorie burn calculations?

Intensity levels adjust base MET values to reflect your effort: Light intensity uses 80% of base MET values (comfortable pace), Moderate uses 100% (challenging but sustainable), and Vigorous uses 130% (maximum effort). This accounts for the increased energy expenditure when you exercise harder, ensuring accurate calorie calculations that match your actual effort level.

Which activities burn the most calories per minute?

High-intensity activities like running fast, competitive cycling, swimming vigorous freestyle, and intense strength training typically burn the most calories per minute due to their high MET values (8-16+ METs). However, the best activities for you depend on your preferences, fitness level, and available time - consistency with enjoyable activities burns more calories long-term than occasional intense workouts you dread.

How do I use calorie burn results for meal planning and nutrition?

Use calorie burn data to inform your nutrition strategy by adding exercise calories to your basal metabolic rate for total daily energy expenditure. If you burn 400 calories during morning exercise, you might adjust your daily calorie intake or post-workout nutrition accordingly. This helps maintain energy balance whether your goal is weight loss, maintenance, or muscle gain.
