This estimates loss from cycling calories only, not diet. It is not medical advice; aim for about one to two pounds per week and combine riding with sensible eating.

The maths

How the calculator works

Weight loss from cycling comes down to the calories you burn adding up over the weeks, then converting that energy into pounds of fat.

1
Per session = MET x 3.5 x weight in kg divided by 200, times your session minutes. Heavier riders and harder efforts burn more.
2
Per week = calories per session x your sessions per week. This is the engine of your weekly deficit.
3
Pounds per week = weekly calories divided by 3,500, the rough energy stored in a pound of body fat.
4
Weeks to goal = your goal in pounds divided by the weekly loss. Ride more or harder to shorten it.
+
Add diet = trimming a few hundred food calories a day stacks on top of this and reaches the goal faster.

The 3,500-calories-per-pound rule is a useful planning estimate rather than a law of physics; real loss slows a little as you get lighter. Treat the timeline as a guide and keep the deficit moderate.

FAQ

Exercise bike weight-loss FAQ

Yes. Indoor cycling burns hundreds of calories per session with very low joint impact, so most people can do it often. Steady rides four to five times a week add up to a meaningful weekly calorie deficit, which is what drives fat loss when paired with sensible eating.

The tool works out calories per session with the MET method (MET x 3.5 x weight in kg divided by 200, times minutes), multiplies by your sessions per week, then divides the weekly burn by 3,500 calories, the rough energy in one pound of fat. That gives an estimated weekly loss from cycling alone.

It depends on how much and how hard you ride. A 180 lb rider doing four 45-minute moderate sessions a week burns about 1,750 calories, roughly half a pound of fat per week, so around 20 weeks for 10 pounds from exercise alone. Adding a small calorie cut from food speeds it up considerably.

Both matter, but you cannot out-ride a poor diet. Exercise creates part of the deficit and protects muscle and fitness, while cutting a few hundred calories a day from food is often the easier lever. The fastest, most sustainable results come from combining the two.

This figure counts calories burned by cycling only, not the extra deficit you create by eating less. It is intentionally conservative so you are not disappointed. Your total loss will be faster once you factor in dietary changes on top of the rides.

Most health guidance suggests aiming for about one to two pounds per week. If your inputs push weekly loss much higher, spread the deficit across diet and exercise and avoid extreme calorie cuts. Slow, steady loss is easier to keep off and better for retaining muscle.
