Abnormal eating schedules affect skin’s protection from harmful UV rays of the sun

Sunbathers may want to avoid midnight snacks before catching some rays. A study in mice from the O’Donnell Brain Institute and UC Irvine shows that eating at abnormal times disrupts the biological clock of the skin, including the daytime potency of an enzyme that protects against the sun’s harmful ultraviolet radiation.

You Asked: Can You Lose Weight Just from Your Stomach?

[brightcove:5438204957001 default]

This article originally appeared on Time.com.

Whether you have some extra weight in your upper arms or rear end, it makes sense that targeting those areas with exercise—curls for your arms, lunges for your butt—would slim them down.

Weight-loss experts refer to this as “spot reduction.” But it turns out that in most cases, this kind of laser-focused weight loss isn’t possible. One study in the Journal of Strength and Conditioning Research found that six weeks of intensive ab workouts did nothing to slim the exercisers’ midsections. A related study found that 12-weeks of one-armed workouts resulted in less loose skin in the trained arm, but zero fat loss.

Working out just one part of your body probably won’t slim it down, but some body parts are more likely to shed fat when you exercise. Your stomach is one of them.

“Some fat deposits are more metabolically active than others, and those may be more responsive to exercise interventions,” says Arthur Weltman, a professor of medicine and chair of the department of kinesiology at the University of Virginia. “Abdominal fat in particular is one of the most metabolically active fats.”

When you exercise, your workouts trigger the release of hormones, Weltman explains. The higher the exercise intensity, the more of these hormones your body pumps out, and the more of that metabolically active fat you lose. (Some of Weltman’s research suggests that high intensity interval training (HIIT), in particular, may slim your midsection.)

If you have fat stored in your gut, arms and chest, a lot of your fat is metabolically active, so it will likely respond to exercise and diet changes, he says. That’s especially true of your abdominal fat. The bad news is that extra fat in these regions is also linked with a greater risk for diabetes, heart disease, cancer and other ailments.

On the other hand, if you store excess fat in the hips, butt and thighs, that fat is not metabolically active. You have a lower risk for many diseases, "but that fat is very hard to reduce,” he says.

What type of exercise is best for targeting the tummy? One studycompared strength training to aerobic training in terms of fat reduction in different parts of the body and found that while aerobic training—running, swimming, cycling—led to greater whole-body fat loss, resistance training targeted abdominal fat in particular.

In a nutshell, spot-targeting fat isn't very effective—in most cases. But if you’re trying to lose fat around your stomach, a mix of resistance training and high-intensity aerobic exercise, along with a healthy diet, may help reduce your belly fat.

Oprah Says Her Weight Troubles Were 'Always Such a Physical, Spiritual, Emotional Burden'

[brightcove:5479177955001 default]

This article originally appeared on People.com.

Oprah Winfrey sunk into a period of depression at age 44 — and she can pinpoint the moment when it happened.

The media mogul had just put her heart into her latest film — 1998’s Beloved — and the movie had opened one day prior.

“I shall never forget Saturday morning, October 17,” Winfrey, 63, tells Vogue for their September issue. “I got a call from someone at the studio, and they said, ‘It’s over. You got beat by Chucky.’ And I said, ‘Who’s Chucky? What do you mean it’s over? It’s just Saturday morning!’ I knew nothing about box office projections or weekend openings. It was ten o’clock in the morning, and I said to Art [Smith, her personal chef at the time], ‘I would like macaroni and cheese for breakfast.’ ”

Laughing, Winfrey says, “And soooo began my long plunge into food and depression and suppressing all my feelings.”

The box office failure of Beloved left Winfrey in a six-week-long depression, though she had trouble recognizing it at first.

“I actually started to think, maybe I really am depressed. Because it’s more than ‘I feel bad about this.’ I felt like I was behind a veil. I felt like what many people had described over the years on my show, and I could never imagine it,” she says. “What’s depression? Why don’t you just pick yourself up?”

Thinking about the positives in her life pulled her out.

“That’s when the gratitude practice became really strong for me,” Winfrey says, “because it’s hard to remain sad if you’re focused on what you have instead of what you don’t have.”

And Winfrey says she’s very different now than she was at 44, when Beloved came out.

“By the time you hit 60, there are just no…damn…apologies. And certainly not at 63,” she says. “And the weight thing that was always such a physical, spiritual, emotional burden for me — no apologies for that either.”

A mismatch of sweeteness and calories could be triggering weight gain, study says

A new research published in the journal Current Biology, which was done by a group of researchers from the Yale University, U.S suggests that diet drinks as well as foods might actually increase weight and thereby trigger diabetes as the brain slows down metabolism when there is a mismatch between sweetness and calories.

Immunotherapy shows promise in treatment of Type 1 diabetes

Around 1.25 million Americans are living with type 1 diabetes and 40,000 new cases are detected each year. In this condition body’s own immune system attacks and damages the insulin-producing β-cells inside the pancreas leading to impaired glucose metabolism in the body. There is no other treatment for this condition than regular painful insulin injections to maintain the normal insulin levels in the body. Type 1 diabetes is currently considered to be incurable.
