Overly restrictive diets are not fit for most in the long run. Some people may like a particular very restrictive diet and do well. But most won't. If they lose weight they will gain it back.

Five Diet Fads From the Last 15 Years That Fizzled Out

Worldwide obesity has more than tripled in the past 50 years. But rather than face up to the root problem of our collective weight gain — over-consuming calories due partly to an abundance of hyper-palatable processed foods, coupled with a sedentary lifestyle — we instead pursue seductive diet fads that promise quick fixes to our bodily malaise.


As an international team of scientists wrote in a paper published in 2022, these diet fads are ultimately ineffective because they tend to promote short-term changes, are excessively stringent in the foods they recommend, are difficult to maintain for a long time, are often nutritionally inadequate, and lack scientific backing.


Over the past 15 years, numerous diet fads have sprung up and ultimately fizzled. Scientific scrutiny and a readily distracted public eager to move on to the next fashionable eating trend led to their demise. Here are five of the most prominent diet fads that died out.


1. Raw food diet

2. Paleolithic diet [there is a modification to this diet that does work well- it adds in fibrous carbs]

3.
Gluten-free diet

4. Detox diet

5. Ketogenic diet
