When Shay Butler and his then-11-year-old son Gavin Butler started a 30-day challenge to eat healthier and lose weight last summer, it was a challenge they planned to do together.

He was excited, Shay Butler said of Gavins reaction. They listed some activities they wanted to do, including swimming, biking, soccer, running and basketball.

When Butler, a digital entrepreneur and vlogger known for his Shaytards YouTube channel, would travel for work, Gavin came along too.

No matter where I was, he traveled with me, Butler said in an interview with the Deseret News. Its been a big relationship-building experience for us.

Their journey along the 30 days is included in their book, Fat Dad, Fat Kid: One Father and Sons Journey to Take Power Away From the F-Word (Atria/Keywords Press, $16.99), which was released Dec. 29. The lime green on the cover, turning the word Fat to Fit, was Gavins idea, Butler said.

One of the biggest challenges they had during the 30 days was not eating sugar.

When youre done with dinner and you want dessert, you want dessert, Butler said. When you cant have dessert, its really, really hard.

But he didnt cheat once.

The only reason I didnt cheat was because of my son, Butler said. Hes strong, hes strong-willed.

And knowing Gavin was keeping his end of their challenge helped Butler stay away from treats and other foods with processed sugar, such as soft drinks.

Gavins perspective is shared through journal excerpts along with several father-son conversations from during the 30 days.

There have definitely been times when Ive really wanted something thats not healthy, and weve been able to talk each other through it, Gavin wrote on Day 16. The other night, I was eating homemade pizza and we talked about how its not healthy to eat another slice just because we want it.

The 208-page book has 30 chapters, one for each day of the challenge, and each chapter is centered around a lesson from the challenge or a life experience that helps contribute to living a healthier lifestyle.

Butler shares about how he got into posting YouTube videos and how it became his familys main source of income, stories from his active childhood, and how he slowly but surely gained weight.

You get more focused on a career and providing for your family than having a healthy body, Butler said. He also shares about his initial weight-loss journey, when he weighed 281 pounds and decided he needed to be healthier.

He signed up to run a marathon, printed the registration and hung it on the refrigerator.

I couldnt even run one mile, he said. I went out for that first run, and I couldnt make it around the block.

The first step was setting a reasonable time frame in which to do it.

I knew that if I worked for six months, I could do it, he said.

He bought a bike and started riding it on a trail along Venice Beach.

I kept going farther and farther every day, he said. I worked up until I could ride my bike 20 miles in one outing, and that was a huge accomplishment for me.

Then he ran the marathon, along with a handful of others. He documented his journey on the ShayLoss YouTube channel.

Butler took the lessons he learned about health and losing weight while training for the marathon and applied them during the 30-day challenge with his son.

The secrets of life are hiding in the word cliche, Butler said. He pointed to eating fruits and vegetables, drinking enough water, getting enough sleep, exercising and working hard.

After the marathons, he was burned out with running, and eventually 30 pounds crept back on, he said.

When the book opportunity came along, he decided he wanted to do the 30-day challenge with his son and write about it.

I just want to motivate people to realize that we have a limited amount of time on this earth and we are alive on it right now, he said. And these memories were creating with our loved ones are the most valuable commodities you can have. In order have more of them and better of them, we need to have healthy bodies.

Butler recognizes hes not an expert.

Ive never claimed to be an expert, he writes in the book. Im just a regular dude trying to lose weight and get in shape, and trying to bring his son along on the journey to find healthier ways to live his life. Regular dudes fail. They mess up and have to start all over again.

Now, his New Years resolution is to not drink soft drinks.

Since Jan. 1, Butler and Gavin have been posting videos representing each chapter of their book along with exercises to do at home on the ShayLoss YouTube channel.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
