Empty calories
In
Research
The lack of complete nutrition found in high energy foods was first scientifically tested by French physiologist François Magendie, who experimented on dogs and described the process in his book Précis élémentaire de Physiologie. He demonstrated that the eating of nothing but sugar, olive oil, or butter could be the cause of the death of his test animals within 30 to 40 days.[5]
Examples
The following foods are often considered[6][7][8][9] to contain mostly empty calories and commonly lead to body weight gain.
- Sugar: such as cookies, sweets, candy, soft drinks, frozen desserts such as ice cream and milkshakes, fruit-flavored sweet beverages, and other foods containing mostly added sugars, including high-fructose corn syrup.
- Fat: such as processed foods and snack products.
- Alcohol: such as spirits, and other alcoholic beverages. While moderate amounts can lead to body weight gain, chronic consumption of large amounts of alcohol can lead to body weight loss because alcoholic liver disease (ALD) is characterized by an increased metabolic rate and impaired muscle protein synthesis, resulting in sarcopenia.[10]
Impact on other nutrients
A diet high in added sugar typically alters behavior to reduce consumption of foods that contain essential nutrients. One study reported that when there was increased consumption of added sugars, nutrients at most risk for deficiency were magnesium and vitamins A, C, E. Intake of these nutrients dropped with each 5% increase in added sugar intake.[11]
A diet high in alcohol can have the same effect, although in this case the nutrients at particular risk of deficiency are
Threshold for health impact
Typically, 90% of energy is expended simply to maintain current weight while idle,[12] but in extremely active individuals physical exercise must be balanced with food intake to maintain healthy body weight. Sedentary individuals and those eating less to lose weight will be subject to malnutrition if they eat food primarily composed of empty calories.[13][14] In contrast, people who engage in heavier physical activity need more food energy as fuel and can have a larger amount of calorie-rich, essential nutrient-poor foods. Dietitians and other healthcare professionals can prevent malnutrition by designing eating programs and recommending dietary modifications according to each patient's needs.[15][16]
The USDA advises the following levels of empty calorie consumption as an upper limit for individuals who engage in 30 minutes or less of
Gender | Age (years) | Total daily calorie needs | Daily limit for empty calories |
