A Brief History of Fad Diets

Posted on 21 November 2016 by Leonie Satori

With a combination of information overload and a penchant for quick fixes, it seems understandable that fad diets and new ways of eating can get confusing and a little jejune.

I am often fascinated with the food choices that people make, when we seem to have an abundance of food available. Knowing what is healthy is hard to identify when we are bombarded with information from family and friends, the internet and media and not to mention the marketing pitches of celebrities and product manufacturers is becoming more and more bewildering.

A Brief History of Fad Diets

So what is a fad diet?

A fad diet is essentially an eating program that promises dramatic weight loss in a short period of time. A fad diet often incorporates a combination of excluding certain foods with increased consumption of some kind of super food or elixir. Lets say that fad diets can be more or less an unhealthy and unsustainable way of eating, but for some these fashionable eating habits seem to draw in the curious and those seemingly desperate to shed kilos, or simply feel better.

When did it all start?

Obviously us humans have been following some varied styles of eating for generations and fashions do come and go. However fad diets came into modern culture in the 20th century, when international communication began to mould our social influences.

The 20th century and fad diets

The grapefruit diet became most popular in the 1930s. The thinking with the grapefruit diet was that consumption of a grapefruit with every meal would stimulate digestion and speed up metabolism. Even today, you may find some weight conscious individuals who may consume grapefruit and black coffee for breakfast. While grapefruit is an excellent food, eating any foods, especially citrus, out of season and in excess is a recipe for digestive discomfort and possible development of food sensitivity. Grapefruit is best consumed in small amounts and really only when grown in season. Grapefruit contains a phytochemical which promotes the production of glutathione, a co-enzyme said to have anti-tumor and antioxidant qualities. Those on medications, with histamine reactions (rashes, allergies, or even asthma) should avoid eating grapefruit in excess.

The 1950s made way for the economical, if not a little odorous cabbage soup diet. The belief with this diet is that you consume, almost exclusively cabbage soup for most of your meals. If the malodorous side effects of this particular diet didn't scare off family and friends, the ongoing noises of your grumbling tummy would. Obviously excluding a good many essential nutrients, the cabbage soup diet is definitely the 'poster girl' of fad diets. Similar to a mono-diet (where you eat only one food at a time) the cabbage soup diet is neither sustainable nor healthy, in fact for many people this has the potential to cause much digestive discomfort. Cabbages are an excellent source of vitamin C, they are high in the amino acid glutamine for soothing the mucous membranes in the digestive tract. Cabbages are also rich in two very cleansing minerals – chlorine and sulphur. These two minerals help to expel the body of wastes, however most of these two minerals are destroyed with overcooking. Enjoy cabbage in moderation, it is especially nutritious when fermented in sauerkraut and kim chi.

A quick skip through the 1960s and 70s with some more than ridiculous fad diets including the cookie diet, the baby food diet and the burger diet. We need not go into too much detail about these fad diets.

Surprisingly, the 1980s showed a renewed interest in the cabbage soup diet. Interestingly, it was in the 80s that the pre-paleo diet or the caveman diet came into popularity … well just for a short period of time anyway. While most of us were basking in the overindulgence of the 80s, there was an undercurrent of individuals who were getting back to nature with eating increased amounts of animal flesh and meats. Perhaps due to the differences in cultural communication at the time, the caveman diet never really reached it's way into the modern vernacular, let alone the Oxford dictionary (more on this diet later).

Low fat diets were popularised in the 80s, with the Pritikin diet showing more of the modern signs of slick marketing and product advertising as we do see today with fad diets. The Pritikin diet viewed fat as the enemy, a common theme that can still be seen today in the supermarket shelves with many commercially available 'low fat' products. While fats were eschewed, high fibre grains were in vogue and the Pritikin muffin was the 'thing' to eat with your low fat decaf coffee with nutrasweet. Fibre is definitely an important component of a healthy diet and plays a big role in healthy digestion and bowel function. However, the downfall with this particular fad diet is in the proportions of nutrients. It was, incidentally in the 1980s that the 'healthy food pyramid' began its circulation throughout Australia (the Swedes have a bit to answer for here). But is consuming 8-12 servings of carbohydrates really going to help with weight loss? Fibre is found in many kinds of foods, including fruits such as pears and apples, all different kinds of vegetables, from the stringy parts of celery to starch fibres in sweet potato, plus fresh cooked wholegrains.

The 1990s turned the philosophy of the Pritkin diet on it's head with seemingly indulgent high fat diets with the zone diet and the Atkins diet. A boon for tired, exhausted and undernourished dieters, these two diets of the 1990s were popularised by celebrities in the media. These two diets seemingly attempted to re-balance the proportions of proteins, fats and carbohydrates in the diet, with an emphasis on low carbohydrate and high fat, however, the Atkins diet particularly was perceived to give the dieter a license to gorge on fatty foods. The subject of scientific studies, the Atkins diet is still being tested for safety and efficacy. But what can realistically be gleaned from the assessments of the zone and Atkins diets is that neither is sustainable for long term healthy eating (the definition of a fad diet). A healthy way of eating includes consuming foods not for their particular fat or protein components, but more for the overall balance of whole nutrients. I would speculate, that this is the point where dietary and nutritional confusion begins to spiral out of control.

The 21st century - an era of fad diets?

Rapidly gaining momentum through increased communication on a global level, it seems everyone is on some kind of fad diet in the 21st century. The 1990s are still influencing the fat, protein and carbohydrate proportions of food and meals, and while so many people are suddenly experts on nutrition, Australia is fast becoming one of the fattest nations in the world.

By the second decade of the 21st century, if you haven't been on a grain free diet, a raw vegan diet, blood type diet or paleo diet you must have been living in a cave (lucky for you). But, 'the paleo diet isn't a fad diet' I hear you exclaim ... or is it? For those of you unaware, the paleo diet (short for palaeolithic diet) is the modern version of the 1980s caveman diet, this diet eschews all types of agricultural foods, including grains, legumes and processed foods. And, although in theory this seems a magnificent way of encouraging healthier eating habits, again it is the balance of eating and consuming only 'paleo foods' without proper understanding of the 'why' is where people lose focus. Avoiding processed food is tantamount to a healthy diet, but does adding coconut oil to your almond milk latte, to drink with your grain free raw paleo brownie make your meal healthy - or is it just adhering to the label guidelines of a paleo diet?

So what is the moral of the fad diet story?

My background in Naturopathic & Ayurvedic nutrition plus a wise, and slightly cynical approach to fad diets encourages me to analyse and question the philosophy of any style of eating. It is good to understand the motives of the person or the group who are behind the theories and design of a particular diet. Question their background in nutrition, and the reason why they suggest consuming said foods and avoiding others. As I have noted with the above fad diets, there is usually some grounding philosophy that can be understood with a diet, however, balanced nutrition and a good healthy, wholefoods plant based diet should not include excessive consumption of any foods, natural or otherwise.

Healthy eating and good nutrition need not be about following a certain style or fashion, it is, essentially about understanding your own personal nutritional needs, which will change through your life. As a consulting Naturopath I act as a guide for people to understand and identify their own health balance, and aid them in making the right kinds of food choices.
