Smoking has a significant effect on an individual's weight. Those who quit smoking gain an average of 4.4 kilograms (9.7 lb) for men and 5.0 kilograms (11.0 lb) for women over ten years. [156] However, changing rates of smoking have had little effect on the overall rates of obesity. [157]
Molecular weights of the species in the representative octane combustion are 114, 32, 44, and 18 for C 8 H 18, O 2, CO 2, and H 2 O, respectively; therefore one kilogram (2.2 lb) of fuel reacts with 3.51 kilograms (7.7 lb) of oxygen to produce 3.09 kilograms (6.8 lb) of carbon dioxide and 1.42 kilograms (3.1 lb) of water.
A 68 kg (150 lb) person walking at 4 km/h (2.5 mph) requires approximately 210 kilocalories (880 kJ) of food energy per hour, which is equivalent to 4.55 km/MJ. [ 15 ] 1 US gal (3.8 L) of petrol contains about 114,000 British thermal units (120 MJ) [ 52 ] of energy, so this is approximately equivalent to 360 miles per US gallon (0.65 L/100 km).
Recommendations on energy requirements in the most medically compromised patients vary, from 5–10 kcal/kg/day to 1900 kcal/day. [ 177 ] [ 178 ] This risk-averse approach can lead to underfeeding, which results in poorer outcomes for short- and long-term recovery.
It is recommended that a cat's diet should contain 4000 kcal per kg of dry food [50] while pregnant; during lactation it is recommended that the cat consumes 240–354 kcal ME per kg of body weight. [50] Studies show that increasing the intake of food for a pregnant animal in order to help it gain weight can have negative effects. [50]
Driving in Formula One is highly demanding physically, with drivers typically burning around 1,000 calories per hour and losing 2–4 kg (4–9 lb) of weight per race. [ 138 ] [ 139 ] A key reason for the physical demands is the extreme g-forces generated by driving at high speeds, with modern Formula One cars capable of generating forces of up ...
