For anyone who wants to get slim or maintain a healthy body weight, reading food labels is widely considered a vital dietary strategy. Supermarkets have thousands of them, those black-and-white Nutrition Facts labels telling shoppers how many calories each portion of a product contains. Many recipes in magazines and diet books also indicate the calories you’ll take in with every serving.

Do you train clients outdoors? You may want to head for verdant forests and lush, grassy settings to boost participants’ mood and energy levels. Being exposed to the color green may be one reason why exercising in nature, also referred to as green exercise, produces physical and mental rewards beyond those that come from exercise alone.

One of life’s certainties is that we’re all aging. It’s also certain, however, that not everyone ages at the same rate. According to recent research, people with type 2 diabetes show signs of aging in their cardiovascular system significantly earlier than those without the disease. Fortunately, exercise can help slow this premature aging, bringing people with type 2 diabetes more in line with others who are not diabetic, says researcher Amy Huebschmann of the University of Colorado School of Medicine.newsletter_teaser: One of life’s certainties is that we’re all aging.
