At the turn of the 20th century, it was fashionable to chew food until liquefied, sometimes up to 722 times before swallowing, thanks to the advice of a popular nutrition expert named Horace Fletcher.

Lore has it that at about the same time, President William Howard Taft adopted a fairly contemporary plan—low fat, low calorie, with a daily food log—after he got stuck in a White House bathtub.

The diet trend coincided with weight gain. Instead, in a cruel twist, it remained low, burning about 700 fewer calories per day than it did before they started losing weight in the first place. Most people who lose weight gain back the pounds they lost at a rate of 2 to 4 lb. The findings also make it seem as if the body itself will sabotage any effort to keep weight off in the long term.
