In 1977, the FDA and CDC began investigating the deaths of people on liquid protein diets, with the front page of the Chicago Tribune proclaiming, Liquid Protein Diet May Kill. By the following year, 58 deaths, primarily of women aged 25 to 44, were linked to these diets. While the exact cause of these deaths remains unknown, it is assumed that the products lacked essential nutrients like potassium and contained poor-quality protein. The liquid protein diet was found to have great potential for damage, and sales dropped by 95% between 1977 and 1978.

What You'll Learn
Cardiac complications
In 1977, the FDA and CDC began investigating the reported deaths of people on liquid protein diets. The FDA issued a warning, stating that at least 16 women had died as a result of using liquid diet products. The following year, it was found that 58 deaths were linked to liquid diets, with all victims being women. The CDC attributed these deaths to "prolonged use of the liquid protein diet".
Several victims died of derangements of heart rhythm that could not be corrected by drugs or electric shock. It is possible that the liquid protein products have a subtle nutritional lacking that creates a crucial deficit over time. Studies have shown that these diets are often nutritionally deficient, lacking the full complement of essential amino acids.
The liquid protein diet is typically very low in calories, with fewer than 400 calories per day. This drastic reduction in calorie intake can lead to cardiac complications, especially when combined with underlying health issues. It is crucial for individuals to consult a medical professional before starting any extreme diet, as unsupervised liquid diets have been associated with serious health risks.
While the liquid diet trend included soups, it also included shakes, milk, frozen yogurt, and other liquid meal replacements. These liquid meals often lacked essential nutrients and could not provide adequate fibre, vitamins, and minerals. As a result, individuals on a full liquid diet may require vitamin and fibre supplements to meet their nutritional needs.

Nutritional deficiencies
The liquid protein products were suspected to have subtle nutritional deficiencies that created crucial deficits over time. A report published by the CDC stated that the diets were usually made from enzymatically digested cowhide, collagen, gelatin, saccharin, and artificial flavoring. The report also noted that the proteins in these diets were "nutritionally of low biological quality," indicating a lack of essential amino acids.
Additionally, it was suggested that these diets might be deficient in essential nutrients like potassium, which is necessary for cardiac function. This could have contributed to the sudden deaths, as several victims died of derangements in heart rhythm that could not be corrected by drugs or electric shock.
While the exact cause of the deaths remains unknown, it is generally accepted that unsupervised liquid protein diets can be dangerous. They may lead to nutritional deficiencies and increase the risk of physiological consequences, especially for those with underlying health issues.
To address nutritional deficiencies, some people on liquid diets may need to take vitamin and mineral supplements. For example, a full liquid diet may not provide enough fiber, so supplements can be recommended to ensure adequate intake. However, it is important to consult a healthcare professional before making any dietary changes or taking supplements.

Lack of medical supervision
In 1977, the FDA and CDC began investigating the deaths of people on liquid protein diets. By the following year, 58 deaths were linked to liquid diets, with victims dying of derangements of heart rhythm. It was found that the diets were purchased without a prescription and were usually made from enzymatically digested cowhide, collagen, or gelatin, with saccharin and artificial flavoring added. The protein in these diets was deemed to be of low biological quality, indicating a lack of essential amino acids.
The liquid protein diet was found to be especially dangerous for women between the ages of 25 and 44, with prolonged use resulting in a significant increase in mortality within this age group. It is now accepted that these diets are unsafe when not supervised by a medical professional.
A full liquid diet consists of fluids and foods that turn to liquid at room or body temperature. It is often prescribed for a short period before a medical procedure or surgery to rest the digestive system. It can also be recommended after surgery on the stomach or intestine, or for those with swallowing difficulties. While it can provide sufficient energy, protein, and fat, it does not provide enough fiber or essential vitamins and minerals.
For this reason, those on a full liquid diet for an extended period need to be under the care of a dietitian and may be advised to take certain vitamins and supplements. It is also important to follow the diet exactly to avoid complications with procedures or surgery.
In summary, the liquid protein diet, particularly when unsupervised by a medical professional, has been linked to a significant number of deaths, especially among young and middle-aged women. The lack of medical supervision, combined with the diet's potential nutritional deficiencies, likely contributed to the tragic outcomes associated with this weight-loss fad.

Poor-quality protein
In the 1970s, a number of deaths were linked to the liquid protein diet. The victims, mostly women, died of derangements of heart rhythm. While the exact cause of these deaths remains unknown, it is assumed that the liquid protein products were nutritionally deficient and lacked essential amino acids.
The liquid protein diet was a fad diet that gained popularity in the 1970s. It consisted of shakes, milk, frozen yogurt, and creamy soups that became liquid at body temperature. The diet was marketed as a quick and easy way to lose weight, and consumers seemed to focus on protein as a key ingredient.
The liquid protein products were typically made from enzymatically digested cowhide, collagen, or gelatin, with saccharin and artificial flavoring added. A report published in 1977 stated that the proteins included in such diets were "nutritionally of low biological quality" and did not contain all the essential amino acids. This suggests that the liquid protein products were made from poor-quality protein.
Additionally, it is important to note that the liquid protein diet was not supervised by medical professionals, which likely increased the risk of health complications. As a result of these deaths, the FDA now requires that all ""very low-calorie" liquid protein diets come with a warning label stating that the product "may cause serious illness or death."

Very low calorie intake
A very low-calorie diet (VLCD) is typically defined as a diet of 800 calories or fewer per day. VLCDs are often used for rapid weight loss and are sometimes prescribed by healthcare professionals for obese patients. While VLCDs can be effective for weight loss in the short term, they are not a sustainable or healthy long-term solution and can have serious health risks, including death.
In the late 1970s, a fad diet consisting of liquid protein products gained popularity. These liquid diets were typically very low in calories, with fewer than 400 calories per day. The products were often made from enzymatically digested cowhide, collagen, or gelatin, with added saccharin and artificial flavouring. They were marketed as a quick and easy way to lose weight and were sold without a prescription under various brand names.
However, it soon became apparent that these liquid diets could be dangerous. Between late 1977 and early 1978, 58 deaths were linked to liquid diets, all of them women between the ages of 25 and 44. The FDA and CDC issued warnings, stating that the low-calorie liquid protein diets had "great potential for damage". Studies suggested that these diets were nutritionally deficient, lacking essential amino acids, potassium, and other nutrients critical for cardiac function.
The exact cause of the deaths remains uncertain, but it is assumed that a combination of underlying health issues and the nutritional deficiencies of the diets played a role. Additionally, the sudden drop in calorie intake can be a shock to the body, especially when not done under medical supervision. As a result of these incidents, the FDA now requires that all "very low-calorie" liquid protein diets carry a warning label stating that the product "may cause serious illness or death."
It is important to note that any significant reduction in calorie intake can have negative health consequences, especially when not done safely and under the guidance of a healthcare professional. A balanced diet that meets an individual's nutritional needs is always preferable to a restrictive diet that could potentially cause harm.
