    For men, the average increase was 168 calories per day (2450 calories in 1971 and 2618 calories in 2000). Most of these extra calories came from an increase in carbohydrate consumption, though there was also an increase in fat consumption over the same time period. [7] The increase in caloric consumption is attributed primarily to the ...

  4. Energy expenditure - Wikipedia

    Obese individuals burn more energy than lean individuals due to increase in the amount of calories needed to maintain adipose tissue and other organs that grow in size in response to obesity. [2] At rest, the largest fractions of energy are burned by the skeletal muscles, brain, and liver; around 20 percent each. [ 2 ]

    This decreased to 51% in the year 2000. [17] Combined with this has been a change to a diet higher in meat and oil, [ 17 ] and an increase in overall available calories. [ 18 ] Available calories per person increased from 2,330 kilocalories (9,700 kJ) per day in 1980 to 2,940 kilocalories (12,300 kJ) per day in 2002. [ 18 ]

    en.wikipedia.org/wiki/Dieting

    Dieting is the practice of eating food in a regulated way to decrease, maintain, or increase body weight, or to prevent and treat diseases such as diabetes and obesity.As weight loss depends on calorie intake, different kinds of calorie-reduced diets, such as those emphasising particular macronutrients (low-fat, low-carbohydrate, etc.), have been shown to be no more effective than one another.

    For an overall efficiency of 20%, one watt of mechanical power is equivalent to 18 kJ/h (4.3 kcal/h). For example, a manufacturer of rowing equipment shows calories released from "burning" food as four times the actual mechanical work, plus 1,300 kJ (300 kcal) per hour, [16] which amounts to about 20% efficiency at 250 watts of mechanical output.

  8. Energy homeostasis - Wikipedia

    en.wikipedia.org/wiki/Energy_homeostasis

    Energy intake is measured by the amount of calories consumed from food and fluids. [1] Energy intake is modulated by hunger, which is primarily regulated by the hypothalamus, [1] and choice, which is determined by the sets of brain structures that are responsible for stimulus control (i.e., operant conditioning and classical conditioning) and cognitive control of eating behavior.

    For all age groups, males on average need to consume higher amounts of macronutrients than females. In general, intakes increase with age until the second or third decade of life. [10] Some nutrients can be stored – the fat-soluble vitamins – while others are required more or less continuously.
