How many calories does gardening burn?

At 3.8 METs, a 70 kg person uses about 133 kcal in thirty minutes. Energy use scales with body weight, so a 90 kg person uses roughly a third more for the same session.

What is the MET value for gardening?

3.8 METs, listed under Compendium code 08239. A MET is a multiple of resting metabolic rate.

Should I subtract my resting metabolism?

If you are adding this to a maintenance figure that already includes rest, yes. The net figure removes the roughly one MET-hour per hour your body would have spent anyway, which for gardening leaves about 74 per cent of the gross total.

Why does body weight change the answer?

A MET value is energy per kilogram of body mass, so the same activity costs more for a heavier body. That is why weight is an input rather than an assumption, and why generic calories-burned figures without a weight are close to meaningless.

How accurate is this figure?

It is an estimate from a population average. Published comparisons against indirect calorimetry find individual discrepancies of twenty to thirty per cent, so use it to compare activities rather than as a ledger to eat back.

Calories burned gardening

This page turns the published MET value for gardening into an energy figure for your body weight. Heavier bodies use more for the same activity, which is why weight is an input rather than an assumption.

Result

These are estimates from population-level equations, not a measurement of you and not medical advice. Individual results vary widely. Talk to a doctor or a registered dietitian before making significant changes to how you eat or train.

The MET value and where it comes from

MET value: 3.8
Compendium code: 08239
Listed as: Weeding, cultivating garden, light to moderate effort
Category: Home and garden

Metabolic equivalents express energy cost relative to rest. Gardening sits at 3.8, which places it in the moderate band on the range the Compendium covers.

kcal = MET × kg × h
     = 3.8 × weight × hours

net of resting:
kcal = (3.8 − 1) × weight × hours

If you already chose an activity multiplier that assumes you train, adding this figure on top counts gardening twice. Use the net figure, or set your activity level to sedentary and add sessions separately.

This figure is an estimate built on an average. Two people doing gardening at the same nominal intensity can differ by twenty per cent or more, and no equation using only weight and time can see that.

Calories burned by body weight and duration

Gross energy in kilocalories. Read across from your weight and down from your duration. A 70 kg person uses about 266 kcal an hour, of which roughly 196 is above what resting would have cost.
