Intermittent Fasting May Help With Weight Loss, Blood Pressure
Obesity is associated with a range of health problems and contributes to an estimated 2.8 million deaths per year worldwide. A recent study suggests following time-restricted eating, a 16:8 diet which entails fasting for 16 hours and eight hours of eating, may help with weight reduction and lowering blood pressure in obese people.
Participants in the study included 23 obese people with an average age of 45 and average body mass index (BMI) of 35. Over the course of 12 weeks, they were allowed to eat any type and quantity of food they wanted between the hours of 10 am and 6 pm. For the remaining 16 hours, they were instructed to only drink water or calorie-free beverages.
When the researchers compared the data from this trial with a matched historical control group from a previous weight loss trial that focused on a different type of fasting, the researchers found that the people who followed the time-restricted diet consumed fewer calories, lost weight, and had improvements in blood pressure. Specifically, they consumed approximately 350 fewer calories, lost approximately 3% of their body weight, and saw an average decrease in systolic blood pressure of 7 mm Hg.
Fat mass, insulin resistance, and cholesterol levels were similar between the fasting group and the control group.
Researchers from the University of Illinois at Chicago conducted the study. It was published on June 15, 2018, in Nutrition and Healthy Aging.
