Mag ik vragen hoe je bij die 28-32 kcal komt?
Resting metabolic rate: 10-11 cal/lb. Women use 10, men use 11. If you work something like the Harris-Benedict equation (which includes age, weight, etc.) for most realistic ranges, it’s always within shooting distance of this value. So I use the quick estimate. For example, I plugged my numbers (37 year old male, 5’7″, 155 lbs) into one of the online calculators and it spit out 1630 calories for RMR. 155*11 = 1705 calories.
Thermic effect of activity: This is always a crapshoot since it can range from a mere 10-20% over basal (if you sit all day) to 100% of basal if you’re involved in heavy activity. Assuming relatively average daily activity and training levels, a 30-50% multiplier is usually sufficient here. So 10-11 cal/lb becomes in the realm of 13-15 cal/lb. This assumes and includes an hour of exercise per day or so.
Thermic effect of food: Although it can vary slightly (especially if you look at extremes of diet), TEF usually amounts to about 10% of the total food intake. So add another 10% to the above. So 13-15 cal/lb becomes 14-16 cal/lb or so.
Non-exercise activity thermogenesis: Of course there’s the additional component of NEAT which can vary massively between individuals. This can’t be readily estimated so I leave it out. It also only appears to be particularly relevant during conditions of overfeeding so I’m not sure it matters much for dieting applications in the first place.
In general, women or those with a ‘slower’ metabolic rate should use the lower value (14 cal/lb) and men or those with a ‘faster’ metabolic rate should use the higher value (16 cal/lb) as a STARTING POINT ESTIMATION for maintenance calories.
A Q&A addressing the estimates I use for both maintenance caloric intake and fat loss.

Als je een TDEE calculator gebruikt kom je ongeveer op hetzelfde uit, het zijn zowat de standaardwaarden die gebruikt worden.
Ik weeg 63 kcal. 63kg *30 kcal = 1890 kcal
Ik vind persoonlijk dat zo'n TDEE calculators je onderhoud altijd heel erg overschatten met die activiteitsfactor, zeker in het geval van krachttraining (want zoveel verbrand je daar niet mee). Dus ik gebruik liever de 28-32 kcal per kg-manier, doe je veel cardio neem je eerder het maximum, zo niet ga je meer naar de lower end. Komt in mijn ervaring ook altijd veel juister uit dan zo'n calculators (zeker als je zo weinig spelingsruimte hebt, iemand met een onderhoud van 3500 kcal zal het niet merken als ie er 100-200 kcal naast zit door zo'n calculator).
