ET Monday, August 2, NOTE: News release was updated to "Cutting not calories daily and exercising may improve heart health in obese older adults" DALLAS, August 2, — Cutting just calories a day with moderate exercise reaped bigger rewards than exercise alone for older, obese adults.
None of the aortic stiffness measures changed significantly in either the exercise-only group or the exercise plus more intensive calorie restriction group. Changes in BMI, total fat mass, percent body fat, abdominal fat and waist circumference were greater in both of the calorie-restricted groups compared to the exercise-only group. Weight loss was similar between the calorie-restricted groups despite nearly two times fewer calories Taking more steps daily may lead to a longer life Obesity during adolescence linked to increased risk of stroke as an adult Calories by the clock?
Fasting on its own, without reducing the amount of food eaten, was just as powerful as calorie restriction with fasting. Fasting alone was enough to improve insulin sensitivity and to reprogram metabolism to focus more on using fats as a source of energy.
The livers of fasting mice also showed the hallmarks of healthier metabolism. The researchers did not study the effect of fasting alone on lifespan or frailty as mice aged, but other studies have suggested that fasting can provide these benefits as well. While the mice that ate fewer calories without ever fasting did show some improved blood sugar control, they also died younger.
Compared with mice who both ate less and fasted, these mice that only ate less died about 8 months earlier on average. The team also measured frailty through metrics like grip strength and coat condition.
The research reveals how difficult diet studies are, even in a laboratory environment. The new study can provide direction to future work trying to answer whether fasting improves human health.
