cook

184 kcal / hour Cook burns approximately 184 calories per hour for a 70 kg (154 lb) adult, and 92 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 131 to 315 kcal.

It carries a MET value of 2.5 in the 2024 Adult Compendium of Physical Activities.

Calories burned cook by body weight

Energy cost scales with the mass you move, so body weight changes the answer more than anything else.

What 184 calories an hour actually means

At MET 2.5, cook counts as light activity — it uses about 2.5 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 3 kcal per minute, or 184 kcal across a full hour.

Within occupation, that ranks 54th of 72 activities by energy cost, a little below sitting, teaching stretching or yoga (MET 2.8) and above bookbinding (MET 2.3).

Put differently: one hour of cook costs about the same energy as 38 minutes of ordinary walking.

On the food side, a can of cola (about 140 kcal) takes roughly 46 minutes of cook to offset at that body weight. That framing is useful for scale, but it is worth saying plainly: exercise and diet are not a ledger that cancels neatly, and appetite tends to rise with activity.

Questions

How many calories does cook burn per hour?

About 184 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 2.5. A 90 kg adult burns closer to 236 kcal in the same hour, because energy cost scales almost directly with body mass.

How many calories does 30 minutes of cook burn?

Roughly 92 kcal at 70 kg, 79 kcal at 60 kg and 131 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.

What is the MET value of cook?

2.5. One MET is the energy you use sitting quietly, so MET 2.5 means 2.5 times that rate.

Is this an exact number of calories?

No, and no calculator can give you one. MET values are population averages measured in laboratory conditions; your own figure varies with fitness, technique, terrain, temperature and body composition. Treat these numbers as a solid estimate for planning, not a precise measurement — and treat any device or site claiming three-digit precision with suspicion.

MET value from the 2024 Adult Compendium of Physical Activities (activity code 11135). Calories computed as MET × 3.5 × weight kg ÷ 200 per minute. General information only — not medical, fitness or nutrition advice. Calorie figures are population estimates and vary between individuals.
