Currently, there is overwhelming evidence showing that consuming fewer calories helps one live longer: this is true whether you’re a single-celled amoeba or a human. Consuming excess calories day after day accelerates aging and then significantly contributes to your death. Simply stated, the results of decades of research confirm that caloric restriction is the only valid, scientifically proven dietary intervention that has been shown to slow the aging process. Also, it can save you lots of money on your weekly food bill.
Now there’s more good news about caloric restriction diets. Scientists at The University of Texas Health Science Center in San Antonio published the results of a study in the journal Aging Cell showing that eating fewer calories may actually be therapeutic for people with various neurological disorders such as Parkinson’s disease, myasthenia gravis and amyotrophic lateral sclerosis (Lou Gehrig’s disease).
The purpose of their research was to try and better understand the mechanisms underlying the benefits of caloric restriction. The researchers were surprised to discover that caloric restriction could directly affect the amount of neurotransmitter secreted by individual neurons in the brain. No one before had observed, or expected, that simply eating fewer calories would change how individual neurons would behave. Their results suggest that modifying the diet might become an effective therapy for improving muscle function during motor diseases such as Parkinson’s disease, myasthenia gravis and amyotrophic lateral sclerosis.
