A new study from the American College of Cardiology has found that the popular ketogenic or "keto" diet may contribute to higher levels of "bad cholesterol" and a twofold increase in the risk of heart attacks and strokes.
“Our study found that regular consumption of a self-reported diet low in carbohydrates and high in fat was associated with increased levels of LDL cholesterol— or “bad” cholesterol—and a higher risk of heart disease,” said Dr. Iulia Iatan, MD, PhD, lead author of the study and attending physician-scientist at the Healthy Heart Program Prevention Clinic in St. Paul’s Hospital.
“To our knowledge, our study is one of the first to examine the association between this type of dietary pattern and cardiovascular outcomes.”
The study points out that depriving the body of carbohydrates such as bread, pasta, and rice forces the body to break down fat for energy instead. This breakdown produces ketones in the liver, hence the name keto. Advocates for this type of diet suggest obtaining 60 to 80 percent of calories from fat.
By comparing this low-carbohydrate, high-fat (LCHF) diet with a more standard diet, the study found that it elevated levels of LDL cholesterol in some people, which is known to elevate the risk of heart disease.
Before starting this dietary pattern, they should consult a healthcare provider," Iatan said. "While on the diet, it is recommended they have their cholesterol levels monitored and should try to address other risk factors for heart disease or stroke, such as diabetes, high blood pressure, physical inactivity and smoking.”
Over 100 world leaders signed on to a pledge at the United Nations COP26 climate meeting with the aim of ending and reversing deforestation by 2030. Leaders agreed to conserve forests and ecosystems, support developing countries on deforestation prevention, and more. Rod Taylor, Global Forests Director at the World Resources Institute, joins Cheddar Climate to discuss the pledge, whether it will have a significant impact, whether 2030 is a suitable deadline, and how we can verify if forests are actually being protected.
President Joe Biden's "Build Back Better" bill could mean cheaper electric bicycles and scooters as the nation attempts to shift away from gas-powered cars. Noa Banayan, the director of federal affairs at PeopleForBikes, joined Cheddar's "Closing Bell" to provide some background on the E-Bike Act included in Biden's reconciliation bill that would provide tax credits for qualified purchases. "We want to make sure, from the bike industry's perspective, that this is a technology and a product that is available to the majority of Americans who want to lower their carbon footprint and get around town faster and do everything that they would normally do in a short car trip but by bike, because it's healthier, it's fast, it's efficient, you're not in traffic," she said.
It's being called the next big trend in crypto. A decentralized autonomous organization, or DAO, is an internet community of different types of groups and businesses. The purpose is to allow people to commit funds to a specific cause in a safe way. Now, one social platform is creating a do-it-yourself kit for those who want to step into the space. Upstream Collective just launched the beta mode of its platform with the goal of putting all facets of running a DAO in one place. Alex Taub, co-founder and CEO of Upstream, joins Cheddar News to discuss.
A NASA spacecraft that will deliberately crash into an asteroid is preparing to launch this week. The goal of the DART mission, or the Double Asteroid Redirection Test, is to hit the smaller of the two asteroids, Dimorphos, with the spacecraft at about 15,000 miles per hour and see how the impact changes the asteroid’s trajectory. Joey Roulette, space reporter at The New York Times, joins Cheddar News to talk more about it.
NFL Hall of Famer and "Good Morning America" host Michael Strahan will be able to add space travel to his list of accomplishments as he prepares to launch into orbit with the next Blue Origin mission.
NASA is gearing up this week for a mission to launch a SpaceX Falcon 9 rocket into a near-Earth asteroid in an attempt to move it slightly off its projected course. Thomas Zurbuchen, an associate administrator for the NASA Science Mission Directorate, joined Cheddar's "Opening Bell" to provide some additional details about the Double Asteroid Redirection Test (DART) and explained why it is necessary as a means to protect Earth.

If you’ve ever watched a show or movie where a character is unconscious for some reason - drowning, electrocution, stabbed in a knife fight - you probably know what to expect next. Some hero will come perform what looks like cardiopulmonary resuscitation (CPR) for a minute or two, perhaps in slow motion, and definitely with a dramatic musical score. And bing, bang, boom, the unconscious character miraculously comes back to life.
If you’ve ever suspected that this is a gross exaggeration of the efficacy of CPR, well, you’re right. But exactly how wrong Hollywood gets CPR is hilarious at best and downright dangerous at worst.
