It’s a Weight-Loss Miracle.
According to a study by the University of Southern California and advanced by the AARP the most effective way to curb your desire to snack is to eat your meals with your nondominant hand. Stop snacking, lose weight. The discomfort you feel may act as mild form of aversion therapy.
This is just one of many advantages of nondominant hand usage identified by multiple research studies. I currently use my nondominant left hand to wave, turn pages in a book, lift a glass and write a phone number as well as many other innocuous activities as it may help maintain mental acuity as we age.
That leaves only one activity that requires my dominant hand to achieve the desired results. Fortunately the frequency of this activity assures that my right hand will never atrophy.
