Empty calories

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.Magendie, F. (1816) "Sur les propriétés nutritives des substances qui ne contiennent pas d' azote", Annales de Chimie (ser. 2) 3:66-77, 408–410.

The following foods are often considered{{cite web |url=http://www.choosemyplate.gov/weight-management-calories/calories/empty-calories.html |title=What are Empty Calories? |publisher=Choosemyplate.gov |access-date=2013-05-21 |archive-date=2014-01-30 |archive-url=https://web.archive.org/web/20140130125320/http://www.choosemyplate.gov/weight-management-calories/calories/empty-calories.html |url-status=dead }}{{cite web|url=http://www.webmd.com/diet/features/beware-empty-calories |title=Beware-Empty-Calories |publisher=Webmd.com |access-date=2013-05-21}}{{cite web|url=http://www.livestrong.com/article/475404-definition-of-empty-calories/ |title=Definition Of Empty Calories |publisher=Livestrong.Com |access-date=2013-05-21}}{{cite web |url=http://caloriecount.about.com/foods-empty-calories-q639 |title=Which foods have empty calories? |publisher=Caloriecount.about.com |date=2008-04-10 |access-date=2013-05-21 |archive-date=2013-05-09 |archive-url=https://web.archive.org/web/20130509090555/http://caloriecount.about.com/foods-empty-calories-q639 |url-status=dead }} to contain mostly empty calories and commonly lead to body weight gain.

• Sugar: such as cakes, 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 margarine, shortening, artificial trans fats, other fats, and oils and foods high in them such as potato chips and most other deep fried and processed foods and snack products.
• Alcohol: such as beer, wine, 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.

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.{{cite journal |vauthors=Marriott BP, Olsho L, Hadden L, Connor P |title=Intake of added sugars and selected nutrients in the United States, National Health and Nutrition Examination Survey (NHANES) 2003-2006 |journal=Crit Rev Food Sci Nutr |volume=50 |issue=3 |pages=228–58 |year=2010 |pmid=20301013 |doi=10.1080/10408391003626223 |s2cid=205689533 }}

A diet high in alcohol can have the same effect, although in this case the nutrients at particular risk of deficiency are zinc, vitamin D, thiamine, folate, cyanocobalamin, and selenium. People with ALD also develop sarcopenia, but it is not clear if this is due to chronic low protein intake or the disease, which is known to inhibit muscle protein synthesis.{{cite journal |vauthors=Dasarathy S |title=Nutrition and Alcoholic Liver Disease: Effects of Alcoholism on Nutrition, Effects of Nutrition on Alcoholic Liver Disease, and Nutritional Therapies for Alcoholic Liver Disease |journal=Clin Liver Dis |volume=20 |issue=3 |pages=535–50 |year=2016 |pmid=27373615 |pmc=4934388 |doi=10.1016/j.cld.2016.02.010 }}

Typically, 90% of energy is expended simply to maintain current weight while idle,{{cite web |last1=Comana |first1=Fabio |title=Resting Metabolic Rate: How to Calculate and Improve Yours |url=https://blog.nasm.org/nutrition/resting-metabolic-rate-how-to-calculate-and-improve-yours |website=blog.nasm.org |access-date=3 March 2024 |language=en}} 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.{{cite web|url=https://www.cdc.gov/healthyweight/calories/index.html |title=Healthy Weight: Caloric Balance | DNPAO | CDC |publisher=Cdc.gov |date=2011-10-31 |access-date=2013-05-21}}{{cite web |url=http://www.health.gov/dietaryguidelines/dga2005/healthieryou/html/chapter6.html#2 |title=A Healthier You - Chapter 6.

Dietitians and other healthcare professionals can prevent malnutrition by designing eating programs and recommending dietary modifications according to each patient's needs.{{cite web|url=http://www.bls.gov/oco/ocos077.htm |title=Dietitians and Nutritionists : Outlook Handbook : U.S. Bureau of Labor Statistics |publisher=Bls.gov |date=2012-07-18 |access-date=2013-05-21}}{{cite web|url=http://www.eatright.org/Public/content.aspx?id=5554 |title=Vitamin and Nutrient Information from the Academy |publisher=Eatright.org |access-date=2013-05-21 |url-status=dead |archive-url=https://web.archive.org/web/20130508060232/http://www.eatright.org/Public/content.aspx?id=5554 |archive-date=2013-05-08 }}

The USDA advises the following levels of empty calorie consumption as an upper limit for individuals who engage in 30 minutes or less of moderate exercise daily.{{cite web|title=Empty Calories: How Many Empty Calories Can I Have? |work=USDA MyPlate 2011 |url=http://www.choosemyplate.gov/weight-management-calories/calories/empty-calories-amount.html |access-date=2014-01-22 |url-status=dead |archive-url=https://web.archive.org/web/20140201202229/http://www.choosemyplate.gov/weight-management-calories/calories/empty-calories-amount.html |archive-date=2014-02-01 }}
