Cycling calories, for your ride.

How this estimate works

Fat Gone stores an intensity value, called a MET, for each activity. One MET represents approximate resting energy use; a higher MET indicates more energy used during the same time. The app estimates basal metabolic rate (BMR) from age, height and weight, then calculates activity energy as BMR ÷ 24 × MET × hours. The calculator above follows that default app method. The app also offers a Harris–Benedict BMR option, so your in-app figure can differ if you choose it.

The default BMR estimate uses the Mifflin–St Jeor equation: 10 × weight in kg + 6.25 × height in cm − 5 × age in years, then +5 or −161 according to the selected formula parameter. It is an estimate of energy use at rest, not a measured metabolic rate. Fat Gone rounds BMR and then the final calorie result, so small differences from other calculators are expected.

Compare cycling effort and ride duration

The table keeps the example profile fixed: age 35, weight 75 kg, height 170 cm and the female formula parameter. Its estimated BMR is 1,477 kcal/day. Change the details in the calculator for your own estimate; the table is a comparison, not a universal calorie chart.

Easy, moderate or vigorous cycling?

The app entries shown here are self-selected cycling efforts. Easy cycling uses 4.3 MET, moderate cycling 7.0 MET and vigorous cycling 9.0 MET. They are broad categories rather than fixed speed bands. Select the effort that best describes the part of your ride you are estimating. A ride with changing effort can be split into separate sessions, calculated individually and added. Do not assign vigorous effort to the entire ride because it includes one difficult hill. The full app catalog offers more specific cycling entries, while this page deliberately keeps the choice short and understandable.

How many calories does 30 minutes of cycling burn?

For the example profile above, the app method estimates about 132 kcal at easy effort, 215 kcal at moderate effort and 277 kcal at vigorous effort for 30 minutes. A full hour at the same modeled effort doubles the unrounded estimate. Your body profile affects the result through the resting metabolic rate calculation, so these examples are not a promise for every rider. The displayed calories include estimated resting expenditure during the ride. If you compare them with a device showing only active calories, the two figures describe different things even before differences in measurement method are considered.

Count riding time rather than the entire outing

Enter minutes spent cycling at the selected effort. Time stopped at a café or waiting at a destination should not be counted as continuous cycling. If a trip lasts 45 minutes but includes 15 minutes off the bike, start with the 30 minutes actually spent riding. Long periods of coasting and frequent stops can also make a broad effort category less representative. Record separate sections when that gives a closer description. The calculator does not read GPS, a power meter or heart rate, and it does not infer your effort from the length of the route.

Why cycling speed is not enough for this estimate

A tailwind, a descent, a different bicycle or riding behind another cyclist can change speed without an equivalent change in effort. A headwind or uphill section can produce the opposite pattern. That is why this page asks for self-selected effort and time rather than claiming to calculate precise energy from distance alone. An electric bike’s assistance is another reason that road speed can be misleading. This tool has no motor-assistance adjustment. When the category does not fit, select an appropriate entry in the full app catalog instead of treating a fast assisted ride as vigorous cycling by default.

Keep estimates useful across repeated rides

Choose a repeatable route or a commute and log its actual riding time consistently. Use the same effort description for comparable sessions, and change it when the ride itself changes. Comparing an easy 60-minute ride with a vigorous 15-minute ride can help you understand the time and effort trade-off, but it should not dictate how hard you must ride. Use Fat Gone to keep cycling alongside walks and household movement in your daily record. Avoid counting a recorded ride again inside another total. Overall weight change depends on the pattern of intake and expenditure over time, not one calculated ride.

What the result can and cannot tell you

This tool estimates gross energy expenditure, which includes resting energy use during the activity. To compare a session with doing nothing for the same duration, subtract the estimated resting portion (BMR ÷ 24 × hours). Neither number is a direct measurement. MET values describe typical activity intensity, while the BMR formula predicts resting expenditure from population data.

Do not convert a single activity estimate directly into expected weight loss. Body-weight change depends on overall intake, expenditure and many other factors over time. The useful habit is to log comparable activities consistently and look for a sustainable pattern. If you are managing a health condition, pregnant, or recovering from an injury, use advice from a qualified clinician when planning activity.

Sources and product method

The selected codes and MET values are from the Fat Gone app’s bundled activity data. The app cites the Compendium of Physical Activities for activity intensity. Its default BMR calculation follows the Mifflin–St Jeor equation. Values are reviewed against the app source when this page changes; the live app remains the source of truth.
