However if we dive into more specific recommendations
by the NIH and Institute of Medicine you'll see there are more variances, mostly due to different total

As researchers in this review pointed out, ``... the 3500 - kcal rule predicts that a person who increases daily energy expenditure
by 100 kcal
by walking 1 mile (1.6 km) per day will lose more than 50 lb (22.7 kg) over a period of 5 years, the true weight loss is only about 10 lb (4.5 kg), assuming no compensatory increase in
caloric intake, because changes in mass concomitantly alter the energy
requirements of the body.»
