16:8 diet helps aid weight loss and lower blood pressure

In daily fasting, or the 16:8 diet, people can eat whatever they like for 8 hours and fast for the remaining 16. A new study evaluates the benefits of this 16:8 pattern for obese individuals and finds that not only does the diet work, but also that it helps to lower blood pressure

More and more people now turn to intermittent fasting as a fast and effective way to lose weight.  There are different form of this diet, depending on the time intervals of ‘fasting’ and ‘feasting.’ The so-called 5:2 diet, for instance, consists of eating normally for 5 days every week and fasting for 2 days.

In the fasting days, the dieter restricts their calorie intake to 500 or 600 per day.

This research was led by corresponding author Krista Varady, an associate professor of kinesiology and nutrition at the University of Illinois at Chicago, and the findings were published in the journal Nutrition and Healthy Aging.

This is the first time researchers have studied the effect of time-restricted eating, where eating is limited to certain times of day, on weight loss among obese people.

Losing weight without counting calories

Varady and colleagues recruited 23 obese study participants who were aged 45 years, on average, with an average body mass index (BMI) of 35.

Between 10 a.m. and 6 p.m., the participants could eat whatever and however much they liked, but they were only allowed to drink water and calorie-free drinks for the remaining 16 hours.

All the study participants were followed for a period of 12 weeks, and their dieting outcomes were compared with those of a previous weight loss trial of another type of intermittent fasting called ‘alternate day fasting.’

In alternate day fasting, they can eat whatever they like for one day and fast for the following day.

On average, when compared with the control trial, those on the 16:8 diet consumed 350 fewer calories, lost 3% of their weight, and had lower blood pressure.

More specifically, the systolic blood pressure of those who fasted daily dropped by an average of 7 millimetres of mercury. However, insulin resistance, cholesterol, and fat mass remained the same between the two compared groups.

As Varady and her colleagues conclude, “These preliminary data offer promise for the use of time-restricted feeding as a weight loss technique in obese adults, but longer-term, large-scale randomized controlled trials are required.”

The study’s corresponding author also comments on the significance of the findings, saying, “The results we saw in this study are similar to the results we’ve seen in other studies on alternate day fasting.”

“But,” she adds, “one of the benefits of the 16:8 diet may be that it is easier for people to maintain. We observed that fewer participants dropped out of this study when compared to studies on other fasting diets.”

“The take-home message from this study is that there are options for weight loss that do not include calorie counting or eliminating certain foods,” said Krista Varady”

“The 16:8 diet is another tool for weight loss that we now have preliminary scientific evidence to support,” Varady concludes. “When it comes to weight loss, people need to find what works for them because even small amounts of success can lead to improvements in metabolic health.”
