Metrecal was a brand of low-calorie, powdered diet foods (to be mixed with water as a beverage) "containing the essential nutrients of protein, carbohydrate, fat, vitamins and minerals" introduced in the early 1960s by the Mead Johnson company, with the first variety going on the market on October 6, 1959, the same day as another Mead Johnson product, Enfamil. [1] Though the initial Metrecal products were criticized for their taste, which newer varieties of flavor tried to improve upon, it attained a niche in the popular culture of the time. Created and marketed initially by C. Joseph Genster of Mead Johnson & Company, it was eventually replaced in the market by competitors such as SlimFast and lost popularity.
Mead Johnson had a long history of creating nutritional supplements for infants (Enfamil) and invalids, and Metrecal was seen as a logical progression into weight loss for the general public. Genster was the group director for nutritional specialties at Mead Johnson, which launched the product in September 1959, though it was unclear who conceived the original concept. [2] Food innovator Sylvia Schur's company provided consulting work on the product's development. [3] The name for the product was generated by an IBM syllable-scrambling program, that when "meter" and "calories" were entered, referring to the measured caloric intake of the diet, the name "Metrecal" was created.
Originally the product came as a powder (containing powdered skim milk, soybean flour, sugar and corn oil and fortified with vitamins and minerals) which was to be mixed with water. Metrecal included more protein than other weight-loss products available at the time. The Metrecal diet plan had people consume four self-prepared shakes (or portion-controlled cans) of Metrecal a day, with each can providing 225 calories for a total of 900 per day. [4]
Many of those trying to subsist on 900 calories per day experienced hunger pangs, which would typically dissipate after a few days. In addition to the original vanilla flavor, later offerings included chocolate and butterscotch along with several other flavors, and the product line was extended to include Metrecal cookies, clam chowder and tuna with noodles. [2] Stating that "most users agree that the stuff is vile-tasting", Time reported that many dieters would add liquor to make it more palatable. [5]
Forbes noted how "Metrecal moved out of the medicine cabinet toward the kitchen, the patio, the pool", while an article in a November 1960 article in Time magazine reported that it was being purchased by "growing hordes of Schmoo-shaped addicts who were insisting on guzzling their way to the vanishing point" who were joined by the royalty of Greece and Saudi Arabia. [5] In her 1963 book The Feminine Mystique , Betty Friedan lamented how women "ate a chalk called Metrecal, instead of food, to shrink to the size of thin young models". [6]
The fad started fading in the mid-1960s, when Peter Wyden, author of the 1965 book The Overweight Society, noted that "even reasonably steadfast dieters simply grew tired" of the monotony of drinking the shakes day after day, as well as copycat products, such as Sego, taking market share. [2] By March 1977, The New York Times said that Metrecal had "gone the way of all flesh" and a spokesperson for Bristol-Myers, which then owned Mead Johnson, acknowledged that "Times change. The market changes." [7] Warnings regarding a wide range of liquid protein weight loss products were issued by the Food and Drug Administration starting later in 1977. [8] In 1978, Metrecal and other similar products were pulled off shelves after the FDA connected 59 deaths, between late 1977 to early 1978, to liquid protein products. [9]
Sucralose is an artificial sweetener and sugar substitute. As the majority of ingested sucralose is not metabolized by the body, it adds no calories. In the European Union, it is also known under the E number E955. It is produced by chlorination of sucrose, selectively replacing three of the hydroxy groups—in the C1 and C6 positions of the fructose portion and the C4 position of the glucose portion—to give a 1,6-dichloro-1,6-dideoxyfructose–4-chloro-4-deoxygalactose disaccharide. Sucralose is about 600 times sweeter than sucrose, three times as sweet as both aspartame and acesulfame potassium, and twice as sweet as sodium saccharin.
Infant formula, also called baby formula, simply formula, baby milk or infant milk, is an ultra-processed food designed and marketed for feeding to babies and infants under 12 months of age, usually prepared for bottle-feeding or cup-feeding from powder or liquid. The U.S. Federal Food, Drug, and Cosmetic Act (FFDCA) defines infant formula as "a food which purports to be or is represented for special dietary use solely as a food for infants by reason of its simulation of human milk or its suitability as a complete or partial substitute for human milk".
A dietary supplement is a manufactured product intended to supplement a person's diet by taking a pill, capsule, tablet, powder, or liquid. A supplement can provide nutrients either extracted from food sources, or that are synthetic. The classes of nutrient compounds in supplements include vitamins, minerals, fiber, fatty acids, and amino acids. Dietary supplements can also contain substances that have not been confirmed as being essential to life, and so are not nutrients per se, but are marketed as having a beneficial biological effect, such as plant pigments or polyphenols. Animals can also be a source of supplement ingredients, such as collagen from chickens or fish for example. These are also sold individually and in combination, and may be combined with nutrient ingredients. The European Commission has also established harmonized rules to help insure that food supplements are safe and appropriately labeled.
Olestra is a fat substitute that adds no calories to products. It has been used in the preparation of otherwise high-fat foods, thereby lowering or eliminating their fat content. The Food and Drug Administration (FDA) originally approved olestra for use in the US as a replacement for fats and oils in prepackaged ready-to-eat snacks in 1996, concluding that such use "meets the safety standard for food additives, reasonable certainty of no harm". In the late 2000s, olestra lost its popularity due to supposed side effects and has been largely phased out, but products containing the ingredient can still be purchased at grocery stores in some countries. As of 2023, no products are sold in the United States using Olestra.
Tang is an American drink mix brand that was formulated by General Foods Corporation food scientist William A.

A very-low-calorie diet (VLCD), also known as semistarvation diet and crash diet, is a type of diet with very or extremely low daily food energy consumption. VLCDs are defined as a diet of 800 kilocalories (3,300 kJ) per day or less. Modern medically supervised VLCDs use total meal replacements, with regulated formulations in Europe and Canada which contain the recommended daily requirements for vitamins, minerals, trace elements, fatty acids, protein and electrolyte balance. Carbohydrates may be entirely absent, or substituted for a portion of the protein; this choice has important metabolic effects. Medically supervised VLCDs have specific therapeutic applications for rapid weight loss, such as in morbid obesity or before a bariatric surgery, using formulated, nutritionally complete liquid meals containing 800 kilocalories or less per day for a maximum of 12 weeks.

Nutritional rating systems are used to communicate the nutritional value of food in a more-simplified manner, with a ranking, than nutrition facts labels. A system may be targeted at a specific audience. Rating systems have been developed by governments, non-profit organizations, private institutions, and companies. Common methods include point systems to rank foods based on general nutritional value or ratings for specific food attributes, such as cholesterol content. Graphics and symbols may be used to communicate the nutritional values to the target audience.
A meal replacement is a drink, bar, soup, etc. intended as a substitute for a solid food, usually with controlled quantities of calories and nutrients. Some drinks come in powdered form or pre-mixed health shakes that can be cheaper than solid foods with identical health qualities. Medically prescribed meal replacement drinks include the body's necessary vitamins and minerals. Bodybuilders sometimes use meal replacements, not formulated for weight loss, to save food preparation time when eating 5-6 meals a day.
Charles Joseph Genster was an American business executive at the nutrition company Mead Johnson who oversaw the development and marketing of Metrecal, a liquid diet drink that became a weight loss craze in the early 1960s.
