Study: Eating Meals Earlier In The Day Can Cut Diabetes Risk And Lower Blood Pressure

In our ongoing dieting dialogue we spend a lot of time talking about what to eat, but what if we’re leaving out something just as important? What if changing when we eat could significantly improve our health? For the first time, a study offers hard data supporting precisely that argument, showing that eating earlier in the day could affect our health as much as what we’re eating.

Animal studies have found that time-restricted diets can reduce diabetes risk by stabilizing blood sugar. To see if the same holds true for humans, a research team from the University of Alabama at Birmingham (UAB) recruited a group of overweight men, all nearly diabetic, to participate in a controlled 10-week study. Half of the group ate three meals a day within a six-hour period starting around 6:30 am and ending by 3 pm (in effect, they fasted for 18 hours a day). The other half ate three meals during a typical 12-hour day. The groups swapped eating regimens at the end of the first five weeks.

By the end of the study, it was clear that eating within a six-hour window versus a 12-hour window produced three big benefits. First, the participants’ insulin sensitivity increased, resulting in better blood sugar control (insulin is the hormone that keeps blood sugar in check; reduced sensitivity to insulin is a hallmark of prediabetes and diabetes). Their blood pressure also improved as much as if they’d been taking an average dose of blood pressure medication. And their appetite was reduced (a paradoxical outcome considering how many hours a day they weren’t eating, but predictable because their blood sugar had leveled out).

The researchers think that the results come from aligning eating times with natural circadian rhythms.

“If you eat late at night, it’s bad for your metabolism,” said lead study author Courtney Petersen, assistant professor in the UAB Department of Nutrition Sciences. “Our bodies are optimized to do certain things at certain times of the day, and eating in sync with our circadian rhythms seem to improve our health in multiple ways.”

Importantly, the benefits didn’t come from weight loss, because all of the participants ate enough calories to maintain their bodyweight. Rather, the results seemed to come directly from changing when they consumed the same amount of calories.

“Our body’s ability to keep our blood sugar under control is better in the morning than it is in the afternoon and evening,” added Petersen, “so it makes sense to eat most of our food in the morning and early afternoon.”

This was a small study of just eight participants and far from the last word on this topic, but as an initial proof-of-concept, the results are important. As diabetes continues to explode across an increasingly obese population, strategies like shifting eating times to stabilize blood sugar could make a big difference. Same for blood pressure – reducing the amount of medication patients take by changing when they eat is an approach that makes sense.

Having said that, time-restricted diets aren’t easy to follow. Compressing every meal between 6:30 am and 3 pm takes commitment and more than a little willingness to endure stomach grumbles, at least initially before blood sugar spikes level out. We’re accustomed to eating dinner in the 5 – 7 pm window, often followed by a snack or two later at night. Changing that mindset takes work.

Further complicating matters is the growing popularity of fasting diets, mostly unsupported by evidence-based science, but fueled, as all diet fads are, by public demand to conquer our bodies’ worst tendencies. The latest study uses a fasting method (since the participants didn’t eat for 18 hours instead of a typical 10 or 12), but the focus wasn’t on restricting calories via fasting, but rather shifting when they’re eaten.

More research with more participants is needed, no doubt, but these preliminary findings are worth some attention. Food choices matter, but when we consume the food we choose may matter just as much.

The study was published in the journal Cell Metabolism.

The Amazing Ways Samsung Is Using Big Data, Artificial Intelligence And Robots To Drive Performance

, Opinions expressed by Forbes Contributors are their own.

Until recently, Korean company Samsung was said to behind its competitors in terms of researching and developing artificial intelligence (AI) technology, but the company’s recent strategy suggests that it’s committed to closing the gap and even competing for the top spot. Since 70 percent of the world’s data is produced and stored on Samsung’s products, the company is the leading provider of data storage products in the world. By revenue, Samsung is the largest consumer electronics company in the world—yes, it has even overtaken Apple and sells 500 million connected devices a year. From industry events to setting goals with AI at the forefront to updating products to use artificial intelligence, Samsung seems to have gone full throttle in preparing for the 4th industrial revolution.

Bringing innovators together

Samsung started 2018 with intention to be an artificial intelligence leader by organizing the Artificial Intelligence (AI) Summit and brought together 300 university students, technical experts and leading academics to explore ways to accelerate AI research and to develop the best commercial applications of AI.

Samsung has Dr. Larry Heck, world-renowned AI and voice recognition leader, on their AI research team. At the summit, Dr. Heck emphasized the need for collaboration within the AI industry so that there would be a higher level of confidence and adoption by consumers and to allow AI to flourish. Samsung announced plans to host more AI-related events as well as the creation of a new AI Research Center dedicated to AI research and development. The research center will bolster Samsung’s expertise in artificial intelligence.

Bixby: Samsung’s AI Assistant

Bixby, Samsung’s artificial intelligence system designed to make device interaction easier, debuted with the Samsung Galaxy S8. The latest version, 2.0, is a “fundamental leap forward for digital assistants.” Bixby 2.0 allows the AI system to be available on all devices including TVs, refrigerators, washers, smartphones and other connected devices. It’s also open to developers so that it will be more likely to integrate with other products and services.

Bixby is contextually aware and understands natural language to help users interact with increasingly complex devices. Samsung plans to introduce a Bixby speaker to compete with Google Home and Amazon Alexa.
