A Brief History of Diets

The idea of dieting - as opposed to having a diet - is fairly new to human history, not really gaining traction within a mass audience until after World War II. Since then the diet industry has surged (to a $64 billion business in 2014), with this fad and that promising better health and less weight. Recently though the growth trend has begun to reverse as more and more people realize that actual nutritionists have been right all along: a varied, balanced diet is best.

Here is a rundown of 60 years of diets.

1950: The Cabbage Soup Diet
           "Lose 10 - 20 pounds in one week!"
           Well ok, but you do it by basically eating water for 7 days.
           Besides being unhealthy, you can't remain on this "diet" for
           very long.

1965: Weight Watchers
           "Follow our point system to maintain balanced, healthy
            eating habits long term."
           Combined with AA-style support groups and a simple to
           follow system rather than a list of permitted and forbidden
           foods, this is one of the few really sensible diet programs to
           come along.

1990: Diet Shakes
          "Simply replace one meal a day with one of our tasty, easy
           to use shakes, and watch the pounds melt off."
           Slim Fast Foods built a following of 23 million people on this
           promise (and $100 million in advertising). There is little
           evidence that it works long term.

1995: Low Fat Diets
          "Cut out the fat to lose weight and protect your heart!"
          Manufacturers rolled out some 1,300 new fat free and low
          fat foods in response to the government's recommendation
          to adopt a low fat diet. They pretty much all crashed and
          burned because the products were packed with sugar.

2000: The Blood Type Diet
          "Customize your diet to your own unique blood type
           and metabolism!"
          This really was a thing. Sadly there is ample evidence
          showing no variation in nutritional requirement by
          blood type.

2003: The Atkins Diet
          "Ultra-low carbs not only solve blood sugar problems
           but improve your health and energy across the board!"
          It also gave people headaches and fatigue and proved
          too difficult for most people to stick with.

2004: The South Beach Diet
          "The realistic Atkins Diet: low carbs and reduced fat."
          This quickly became the best selling diet book of all time
          and is one of the better approaches and still popular today.

2015: Gluten Free
          "Eliminate this wheat protein from your diet an enjoy
           almost unlimited benefits."
           Perhaps 3% of the US population needs to be on a gluten
           free or reduced gluten diet. The rest apparently just likes
           to eat whatever is popular in Hollywood.

2016: The Paleo Diet
          "If it worked for cave people it will work for us!"
          Experts warn that the diet, which attempts to recreate the
          meat heavy, grain and dairy free diet of our paleolithic
          ancestors is dangerously misguided. The meats available
          to our ancestors is not available to us but were "biologically
          distinct". Also, the food groups eliminated have significant
          nutritional benefits.

2017: The Ketogenic Diet
         "Burn fat instead of carbs!"
         Originally developed as a treatment for pediatric epilepsy,
         this diet forces your body into a potentially dangerous state
         of ketosis. Ketosis occurs when people eat a low- or no-carb
         diet and molecules called ketones build up in their
         bloodstream. It can indeed help you shed a few pounds, but
         Ketosis is actually a mild form of ketoacidosis. Ketoacidosis
         mostly affects people with type 1 diabetes. In fact, it is the
         leading cause of death of people with diabetes who are
         under 24 years of age.

Since 2018, eating plans promoting balance and variety began making headway. The DASH, Mediterranean and Flexitarian diets were ranked #1, #2 and #3 on the US News and World Report diet plan listing. Atkins, Paleo and Ketogenic were the worst three diets evaluated.
