Intermittent fasting could cut weight and delay aging – but there’s a problem – SlashGear

Published

 on


Intermittent fasting could unlock lower rates of cancer and obesity as well as cut stress and even make us live longer, new research suggests, but significant hurdles are getting in the way of the diet’s advantage. Rather than the typical current diet plan of three meals per day, spread out fairly evenly through daylight hours, intermittent fasting sees people squeeze their meals into just a handful of hours.

It’s not a new concept, but it has gained traction in recent years with the rise of so-called “paleo” diets and greater attention paid toward atypical eating routines. At the same time, studies have looked at potential health and lifestyle benefits, focusing on how intermittent fasting can prompt what’s known as a metabolic switch, the body shifting from using glucose-based to ketone-based energy.

Usually, those following an intermittent fasting plan would eat within a six hour window each day, and then fast for the remaining 18 hours, though some extend that to as much as 20 hours. The potential benefits from that are more than just around weight loss. According to a new review by Rafael de Cabo, Ph.D., and Mark P. Mattson, Ph.D., of John Hopkins University School of Medicine, “many of the health benefits of intermittent fasting are not simply the result of reduced free-radical production or weight loss.”

Benefits of intermittent fasting

According to the review, “intermittent fasting elicits evolutionarily conserved, adaptive cellular responses that are integrated between and within organs in a manner that improves glucose regulation, increases stress resistance, and suppresses inflammation.” During periods of fasting, the body’s cells would normally shift into processes where damage is removed or repaired, and cellular stress is addressed. However, given the meal cadence of the typical diet, the processes don’t have much time to work.

One of the best-known benefits of intermittent fasting is a change in how the body generates its energy. After a meal, glucose from food is used for energy; fat is stored for later use. When fasting, that fat is broken down in turn, with the liver converting fatty aides to ketone bodies.

Those ketone bodies aren’t just a sign of fat being broken down, but act as “potent signaling molecules” for our cells and organs. For example, they can influence how proteins, molecules, and genes that influence factors like aging, neurodegenerative disorders, and overall health – among other factors – are produced. Other studies found intermittent fasting could also help improve glucose regulation, manage blood pressure, and cut down on body fat.

The problem with intermittent fasting

While the science may be there, the lifestyle changes for intermittent fasting are a much bigger issue, the study’s authors conclude. Perhaps the biggest issue is that we’re just not in the habit of abstaining for extended periods of the day.

“First, a diet of three meals with snacks every day is so ingrained in our culture that a change in this eating pattern will rarely be contemplated by patients or doctors,” they suggest. “The abundance of food and extensive marketing in developed nations are also major hurdles to be overcome.”

There are also barriers to sticking with such a diet, like the inevitable hunger, irritability, and a loss in concentration. That’s usually limited to the first month, the researchers point out, but it can be a significant hurdle during that period, and it relies on healthcare professionals making clear that it’s a temporary side-effect. Problem is, it’s also suggested, physicians themselves often lack the training to give good intermittent fasting advice.

Could a pill replace intermittent fasting?

One other avenue of research, mainly in animal models, has been the hunt for a pharmacologic alternative: a pill that replicates the benefits of intermittent fasting. That has included drugs that impose the same sort of challenge to the body’s metabolic system that fasting does, or that specifically triggers the sort of processes that go on during ketosis.

We’re still some way from a pill that can do that, however. According to the researchers, “the available data from animal models suggest that the safety and efficacy of such pharmacologic approaches are likely to be inferior to those of intermittent fasting.” In short, if you want the best results, you need to stick to the diet.

The best intermittent fasting diet

There are several diet structures that all fall under the umbrella term of “intermittent fasting,” and there’s no one single perfect meal plan for every person. The most common is probably the daily time-restricted feeding regimen, where you eat within a period of around six hours, and then avoid food for the remaining 18 hours period.

However there’s also the 5:2 intermittent-fasting regimen to consider. That limits daily calorific intake to just 500 calories on two days per week, with regular healthy eating on the remaining five days. Whichever structure is picked, there should be a focus on exercise and meal nutrition too.

What intermittent fasting shouldn’t be, though, is a sudden blow to the system. That, at the very least, is a recipe for quickly giving up on the diet. Instead, a four month transition period – preferably with regular monitoring of body weight, along with glucose and ketone levels – is recommended, in the hope of making a long-term behavioral change that maximizes the diet’s potential benefits to health.

“It’s Breast Cancer Awareness Month and I’m stretching my quads before joining my friends at Kit Undergarments and Third Love as they kick it to cancer by donating 15% of sales from the Kits To Kick Cancer collection to Women’s Cancer Research Fund,” the mother-of-three wrote to her more than 14 million followers.

The Fabletics co-founder’s post was met with praise, not just for bringing attention to the worthy cause, but for her strong and toned figure. 

Hudson’s post drew comparisons to fellow A-list celebrities like, Jennifer Lopez and Jennifer Aniston

“OK, I had no idea she was this ripped,” one person commented, while another added, “Definitely thought that was J.Lo at first glance.”

“I thought you were Jennifer Aniston at first,” someone else chimed in. “Can you imagine being a mom and 42 and looking this good? I am in shock.”

“Girl, you are in crazy good shape,”another commented. “I hope I look like this when I’m in my 40s.”

“The hair is irrelevant when you’re a mom with a body that looks this great,” someone else added.

“Thank you for promoting Breast Cancer Awareness Month and thank you for being this freaking hot,” another fan praised. “Keep up the hard work, sis. I see those abs!”

It’s no secret that the “How to Lose A Guy In 10 Days” star works hard for her body. In an interview with Women’s Health in June, Hudson revealed that she works out three or four times per week with a personal trainer. 

“I know I’m at my strongest is when I’m doing my Pilates because it never gets easier,” she said. “The more you do Pilates the harder the things you can do become. I love how flexible I feel and I like what it does to the shape of my body.”

Aside from pilates, Hudson prefers to keep her exercises as fun as possible. 

“I like to do any kind of dance workout,” she added. “I have the Peloton Tread, I just got it and I love Peloton. I think they make it so easy to have ‘no excuse’ workouts.”

Delta variant likely slammed brakes on U.S. economic growth in third quarter

Published

 on

The U.S. economy likely grew at its slowest pace in more than a year in the third quarter as COVID-19 infections flared up, further straining global supply chains and causing shortages of goods like automobiles that almost stifled consumer spending.

The Commerce Department‘s advance gross domestic product report on Thursday is also expected to show strong inflation, fueled by the economy-wide shortages and pandemic relief money from the government, cutting into growth. Ebbing fiscal stimulus and Hurricane Ida, which devastated U.S. offshore energy production at the end of August, also weighed on the economy.

But there are signs that economic activity picked up towards the end of the quarter amid declining coronavirus cases driven by the Delta variant.

“Delta is the biggest reason why we have this noticeable deceleration,” said Ryan Sweet, a senior economist at Moody’s Analytics in West Chester, Pennsylvania. “We’re going to see growth re-accelerate in the fourth quarter and the first half of next year as the effect of the Delta variant begins to wane. It doesn’t mean that we won’t have future waves of COVID, but with each passing wave, the economic costs continue to diminish.”

GDP growth likely increased at a 2.7% annualized rate last quarter, according to a Reuters survey of economists. The poll was, however, conducted before the release of data on Wednesday showing a sharp widening in the goods trade deficit in September amid a slump in exports.

The biggest goods trade deficit on record prompted some Wall Street banks to cut their GDP growth estimate, including Goldman Sachs, which trimmed its forecast by half a percentage point to a 2.75% rate. The Atlanta Federal Reserve trimmed its already low forecast to a 0.2% pace from a 0.5% rate.

Regardless of the actual number on Thursday, the economy’s performance last quarter was probably the weakest since the second quarter of 2020, when it suffered a historic contraction in the wake of stringent mandatory measures to contain the first wave of COVID-19 infections. The economy grew at a 6.7% rate in the second quarter. The Delta variant worsened labor shortages at factories, mines and ports, gumming up the supply chain.

The anticipated meager growth is seen coming mostly from a moderate pace of inventory drawdown. Overall inventory accumulation likely remained weak owing to shortages, especially of motor vehicles. Outside the shutdown in spring 2020, September was the worst month for motor vehicle production since 2010 because of a global shortage of semiconductors.

“The largest boost to GDP should come from a slower drawdown of inventories compared to in the second quarter, as supply shortage issues initially presented through weaker inventories but now have become a constraint on consumption instead,” said Veronica Clark, an economist at Citigroup in New York.

Consumer spending, which accounts for more than two-thirds of U.S. economic activity, is forecast to have stalled after a robust 12% growth pace in the April-June quarter. Though automobiles will account for a chunk of the anticipated stagnation, the Delta variant also curbed spending on services like air travel and dining out.

GLIMMERS OF HOPE

Inflation, which overshot the Federal Reserve’s 2% flexible target, also reduced households’ spending power. Price pressures and the supply chain disruptions saw the International Monetary Fund this month cutting its 2021 growth estimate for the United States to 6.0% from 7.0% in July.

Slower growth will have no impact on the Fed’s plans to start reducing as soon as next month the amount of money it is pumping into the economy through monthly bond purchases.

But there is light at the end of the tunnel. The summer wave of COVID-19 infections is behind, with cases declining significantly in recent weeks. Vaccinations have also picked up. The improving public health helped to lift consumer confidence this month. The number of Americans filing new claims for unemployment benefits has dropped to a 19-month low.

That declining trend is expected to be confirmed by a separate report from the Labor Department on Thursday.

According to a Reuters survey, initial claims for state unemployment benefits likely held at a seasonally adjusted 290,000 last week. That would mark the third straight week that claims remained below the 300,000 threshold.

Economists are split on whether business investment in equipment maintained its pace of double-digit growth last quarter. Data on Wednesday showed a surge in shipments of capital goods excluding aircraft in September.

While some economists saw this as an indication of strong equipment spending, others cautioned that high prices flattered the value of shipments. There are also concerns that the scarcity of motor vehicles hindered efforts by companies to replace or increase their auto fleet.

“Just as the collapse in motor vehicle sales is dragging down consumption, the corresponding collapse in fleet sales is also weighing on business equipment investment,” said Michael Pearce, a senior U.S. economist at Capital Economics in New York. “The sharp fall in auto and truck shipments means that, rather than a double-digit annualized gain, business equipment investment probably contracted slightly in the third quarter.”

Trade was likely a drag on GDP growth for a fifth straight quarter also following a sharp drop in industrial materials exports in September. Expensive building materials and soaring house prices likely weighed on the housing market again last quarter, while government spending probably rebounded.

Confused about COVID-19 booster shots? Here’s what you need to know – North Delta Reporter

Published

 on


The province announced that COVID-19 booster shots will be available to every British Columbian ages 12 and up by the end of May 2o22.

The announcement came after months of health officials saying simply that they were studying the science of booster shots and who would need them.

So, what is the science?

Provincial health officer Dr. Bonnie Henry said that while two doses of a COVID-19 vaccine are absolutely effective in preventing hospitalization from the virus, some groups are starting to see breakthrough cases. This is most likely to happen in older individuals, the immunocompromised and Indigenous Peoples – and that’s why those groups are being prioritized. The immunocompromised – about 115,000 people – have already received an invitation to get their third dose, as have residents in long-term care and assisted living.

As time goes on, however, other people may also become vulnerable, especially those who got their vaccines in the winter and early spring. That includes many seniors, the clinically extremely vulnerable and Indigenous Peoples.

“Our vaccines are highly effective. However, we are starting to see a gradual decline in protection over time. As a result, we are taking the proactive step of expanding boosters to everyone in our province,” said Henry. “We’re starting with the people who need them most to continue to do all we can to keep people in B.C. safe from this virus and its variants.”

What shots will be offered as boosters?

Booster shots will be either Pfizer or Moderna mRNA vaccines, including for individuals who received one or two doses of AstraZeneca. Health officials say it doesn’t matter which of the mRNA shots you get as a booster – they are interchangeable.

Do I have to get it?

No. Health officials say that for the purposes of the B.C. vaccine card program and for immunization mandates – such as for health care workers – two doses will be sufficient.

When will I be eligible?

That depends. In general, the goal is for everyone to get their booster shot six to eight months after they received their second dose. Long-term care residents and immunocompromised individuals are already eligible, but here’s who comes next:.

From now until the end of 2021:

  • Seniors 70+
  • Indigenous Peoples 12+
  • Long-term care support clients
  • Seniors in independent living
  • Health care workers who got dose one and dose two in a shorter interval.

From January to May 2022

  • Clinically extremely vulnerable (who are not immunosuppressed)
  • Health care workers in acute care, long-term care and assisted living
  • Health care workers in the community
  • Everyone in B.C ages 12+.

How will I find out when I’m eligible?

Everyone will be contacted via the Get Vaccinated system, the same way you were likely contacted for your first two shots. If you’re not registered yet, you can do so at getvaccinated.gov.bc.ca or by calling 1-833-838-2323. If you are already registered from your first two shots, you don’t need to register again.

Where can I get the shot?

Booster shots will be available at community immunization clinics run by health authorities and pharmacies across the province. In small or remote communities, everyone may be vaccinated at the same time through a “whole of community system,” as happened in places such as Tofino and Prince Rupert for first and second doses.
