Dietary tweaks using certain vegetables and healthy fats can increase levels of serotonin, which is linked to better mood, said registered dietitian nutritionist Michelle Smith. RDN Michelle Olsen said skipping meals can adversely affect mood and leave people open to stress and the temptation to eat unhealthy foods.
Recent research linked Western diets high in meat products to adverse environmental effects, and registered dietitian nutritionist Sharon Palmer said studies consistently show that reducing consumption of animal food and eating a plant-based diet can reduce the impact on the planet. Palmer said while a vegetarian or vegan diet is not for everyone, people can adopt a flexitarian diet plan, in which they reduce but don't give up meat.
A study in the Journal of the American Medical Association, which included more than 1,400 adults who had roux-en-Y gastric bypass surgery, linked the rate of regained weight to the likelihood of future health problems. Researchers said a person who lost 150 pounds after surgery but regained 28 pounds had a 51% higher risk of diabetes progression and a 28% higher risk of decreasing physical-health-related quality of life.
Youths with autism spectrum disorder and those with developmental delays had 1.57 times and 1.38 times increased odds of being overweight or obese, respectively, compared with those in the general population, according to a study in the Journal of Pediatrics. The findings, based on data involving about 2,500 children ages 2 to 5, also showed a 1.7 times higher overweight or obesity risk among those with severe ASD symptoms, compared with those with mild ASD symptoms.
Spanish researchers analyzed data on 3,896 adults ages 60 and older and found that any of the components of the FRAIL scale -- fatigue, illness, limitation in ambulation, low resistance and weight loss -- was associated with an increased risk of all-cause mortality, while pre-frail and frail people were at a higher risk of dying from cardiovascular disease, compared with robust individuals. The findings in the Journal of the American Geriatrics Society showed that CVD-related death rates among physically active but frail individuals were the same as those for pre-frail and physically inactive people.
A study in the Journal of Diabetes and its Complications showed an association between adverse experiences in childhood and an increased risk for developing prediabetes indicators in adulthood, such as higher body mass index, insulin resistance or waist circumference. Researchers used a cohort of 1,054 individuals with a mean age of 55 and found that physical abuse was tied to increased fasting insulin levels and waist circumference, while sexual abuse and financial strain correlated with an increased BMI.
