Keys to Successful Aging: Calorie Restriction or Exercise

Which is more important for “Successful Aging”, Calorie Restriction or Exercise?


With an interest in successful aging, a recent article in Exercise and Sports Sciences Reviews by Nicholas Broskey et al caught my attention. In the article, they discuss the concept of primary and secondary aging and hypothesize that both exercise and calorie restriction improve secondary aging but only calorie restriction improves primary aging.
As they outlined, primary aging is the variable progression of the age related decline in physiological homeostasis related to energy expenditure and oxidative stress. The oxidative stress is related to free radical production secondary to the higher energy expenditure seen in humans. Secondary aging is related to the external influences from disease, environmental exposure and lifestyle choices. Two common causes of secondary aging relate to the combination of overeating leading to weight gain associated with lack of physical exercise. This leads to impaired mitochondrial function and amplified oxidative stress which contributes to primary aging. Clearly the process of primary and secondary aging are interrelated – our lifestyle choices impact both types of aging.
They conclude that calorie restriction, but not exercise, reduces metabolic rate and decreases oxidative stress and has more impact on primary aging. Physical activity alone has not demonstrated the same improvements. With secondary aging, which is impacted by our lifestyle choices, both exercise and calorie restriction are powerful tools. It will be interesting to watch this area of research over time. However, clearly there is benefit from healthy nutrition and regular physical activity if we want to be “successful agers”. We should continue to promote both for our patients and our health care system.

Bike Share Programs and Exercise Prescription

Bike Share Programs and Exercise Prescription

On recent travels, we have seen evidence of the increasing interest in bike sharing services. Bike share programs have been around since the 1960’s in Europe, but only recently have taken off worldwide with increasing affiliation with communities and government and quick payment access through various apps. Bike sharing services have faced challenges but clearly have health benefits, can lead to cost savings for individuals, they decrease the impact of travel on the environment and allow an increase in exercise while outdoors. As promoted by Cycling CME and many others, exercise should be considered medicinal – exercise as medicine. This is the main focus of the organization, “Exercise Is Medicine” and is promoted worldwide.

A recent initiative in the UK has gone an extra step toward the health benefits by promoting the bike share program to patients at a medical center. Patients at medical centers in Cardiff, Wales will be offered 6-month subscriptions to a bike-rental service that will allow the user unlimited bike rides. This follows a similar initiative in Boson where physicians could “Prescribe-a-Bike” through a bike share program. These two programs are excellent examples of initiatives aimed at increasing the amount of exercise to improve an individual’s health using a practical and fun application. As cycling and exercise promoters, we hope that other communities and health systems will embrace these types of innovative projects.
