Meal Timing & Not Fasting Could Be A Key Reason You’re Not Losing Fat

  • The Facts:A couple of new studies outline the importance of meal timing when trying to lose weight and burn fat.
  • Reflect On:Why has fasting never been a medical intervention tool when it’s clearly extremely healthy and beneficial to the body in multiple ways?

Years ago, if a person withheld from eating for long periods of time in order to lose weight, it would work, but a common response from peers might have been, “Yeah, but you did it the unhealthy way.” Today, many more people are aware that caloric restriction and fasting are actually a great, safe, healthy and effective way to lose weight and shed fat from your body. In layman’s terms, when you fast, your body runs out of its glycogen (sugar) reserves, and when that happens it switches to fat burning mode. Fasting is now recognized as an effective tool to regenerate stem cells, kill cancer cells, repair damaged DNA, and help ward off and treat numerous age-related diseases like Parkinson’s and Alzheimer’s disease. It’s even been known to completely reverse type 2 diabetes. Every single study that has examined fasting or caloric restriction in living organisms has shown tremendous biological effects. Our biology is clearly built for it, and the ancients definitely knew what they were talking about. Modern day science has even confirmed it.

We don’t hear much from the mainstream medical industry regarding fasting, and the answer to that is simple, it’s because money can’t be made off of it. The science will only become popular when a pill, for example, is developed that mimics the effects of fasting. That would be unfortunate.

Long term fasts as well as intermittent fasting are, again, great ways to burn fat and lose weight, but that’s effective only when your eating periods are healthy. In my opinion, fasting combined with a whole foods, plant-based diet is what one needs to do if they want to optimize their health, and there is a tremendous amount of science to back that up.

A great place to start your research is at The Intensive Dietary Management. In addition to searching through all of the peer-reviewed literature that’s available online about fasting and caloric restriction, this blog is a great resource, which is primarily written by Dr. Jason Fung, a Toronto-based nephrologist who uses fasting to treat his diabetes patients.

On his blog, I came across some information that shows how important the times we choose to eat may be if you are looking to reduce fat and/or lose weight.

He points out an interesting study from Satchin Panda, a professor at the Salk institute. The study examined current eating happens tracked via a smartphone app.

The 10% of people who ate the least frequently, ate 3.3 times per day. That is, 90% of people ate more than 3.3 times per day. The top 10% of people ate an astounding 10 times per day. Essentially, we started eating as soon as we got up, and didn’t stop until we went to bed.

The median daily intake duration (the amount of time people spent eating) was 14.75 hours per day. That is, if you started eating breakfast at 8 am, you didn’t, on average, stop eating until 10:45! Practically the only time people stopped eating was while sleeping. This contrasts with a 1970’s era style of eating at 8am breakfast and dinner at 6pm, giving a rough eating duration of only 10 hours. The  ‘feedogram’ shows no let up in eating until after 11pm. There was also a noticeable bias towards late night eating, as many people are not hungry in the morning. An estimated 25% of calories are taken before noon, but 35% after 6pm.

When those overweight individuals eating more than 14 hours per day were simply instructed to curtail their eating times to only 10-11 hours, they lost weight (average 7.2 pounds) and felt better even though they were not instructed to overtly change what they ate, only when they ate.

The circadian rhythm seems to suggest that late night eating is not good for weight loss since excessive insulin is the main driver of obesity, and eating the same food early in the day or late at night have different insulin effects. You can learn more about the circadian rhythm of fasting here.

You can find some strategies on how to go about this type of time-restricted eating here, and as Dr. Fung mentions: “It took participants 12 days on average to adjust to this way of eating, It can take up to 3 or 4 weeks to adjust. Most found the fasting period relatively easy to adhere to, but more difficult to adjust to the time restriction.”

The Takeaway

This is just a brief write up about fasting and the importance regarding what time of day you eat if you are trying to lose weight and shed fat from your body. Please follow the links within the article for more details and information. We’ve published a number of articles on our website regarding fasting and cited lots of science, so feel free to browse through there. Some of those articles are linked earlier in this article as well. It’s not that simple, but if you want to improve your health and lose weight, fasting combined with a healthy diet and perhaps some time-restricted eating is a guaranteed way to do so.

Greenland is losing ice seven times faster than expected

Greenland is ceasing to be that vast white territory because it is losing ice at a speed seven times faster than in 1990.

The fatal scenario goes according to the context of global warming of Intergovernmental Panel on Climate Change (IPCC), which would expose 400 million people to coastal flooding in the year 2100.

A joint work of 96 scientists from 50 international organizations has generated the most detailed image so far of the ice loss from Greenland.

The team called Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) used 26 surveys to calculate changes in the Greenland ice sheet mass between 1992 and 2018.

The worst case scenario

The research results show that Greenland has lost so far 3.8 billion tons of ice, since 1992. This thaw is enough to raise the sea level by 10.6 millimeters.

The figures are alarming as they show a seven-fold increase in ice loss in just three decades.

In 2013, the IPCC predicted that worldwide sea level would rise 60 centimeters by 2100, leaving 360 million people at risk due to coastal flooding. However, the new study shows that the ice loss is increasing faster than expected, which would generate an increase of even 7 centimeters more at sea level.

Andrew Shepherd in the University of Leeds, lead author of the research, he said in a statement:

As a general rule, for every one-centimeter increase in global sea level, another six million people are exposed to coastal flooding across the planet.

According to current trends, the melting of ice in Greenland will cause 100 million people to flood each year at the end of the century, which adds up to 400 million in total due to all the sea level rise. These are not unlikely events or small impacts; they are happening and will be devastating for coastal communities. ”

Caused by warming

The climate models regionals used by the team of researchers showed that half of the ice loss was due to rising air temperatures. The other half was caused by the rising ocean temperature.

The doctor. Erik Ivins of the Jet Propulsion Laboratory NASA and lead author of the study said in a statement:

Polar ice satellite observations are essential to monitor and predict how the climate change could affect ice losses and sea level rise. While computer simulation allows us to make projections from climate change scenarios, satellite measurements provide irrefutable evidence. ”

The team expects to continue monitoring the ice reduction in Greenland to determine the possible sea surge each year.

The research findings have been published in the journal. Nature.

Bright Meteor Fireball Streaks over Phoenix, Arizona

Does it seem like these are on the rise?

via AZ Central:

By now, we all know, it didn’t really happen unless it’s confirmed via social media.

And that’s what was happening Friday night, as numerous Twitter posts surfaced from people who said they saw a bright light streak across the nighttime sky over Phoenix sometime around 9:30 p.m.

The posts described the sight as a green streak or light, possibly a large meteor or “shooting star,” but definitely more than a quick flash that such a phenomenon usually produces.

The Arizona Republic could not immediately confirm the source of the bright light, but several other Twitter posts reported seeing it from vantage points such as 32nd Street and Thomas Road, near the Phoenix Art Museum, or in north Phoenix.

Life on Earth can be explained by asteroid-eating bacteria

A new study suggests that asteroids can be a food source for living things, more specifically a microorganism called  Metallosphaera sedula , a metal-eating species.

Metallosphaera sedula  is a species of bacteria-like microbes, originally isolated from a volcanic field in Italy. The first part of the name can roughly be translated as a “metal mobilizing sphere,” while the word “sedulus” means busy. This describes the efficiency of these organisms in mobilizing metals, including those found in asteroids.

According to research led by University of Vienna astrobiologist Tetyana Milojevic, these microbes derive their energy from inorganic substances through oxidation, and can collect energy sources faster from extraterrestrial rocks than from simple ancient terrestrial minerals. Milojevic explains that the study was conducted to find “microbial fingerprints” left in meteorites. “This should be useful for tracking life-seeking biosignatures in other parts of the universe,” she concludes.

This kind of research, according to the astrobiologist, can provide her colleagues with “little tips” on what they can look for in their search for alien life. “If there was ever life on another planet, similar microbial fingerprints may still be preserved in the geological record,” she said.

The team examined how Metallosphaera sedula  interacts with NWA 1172, a rocky meteorite found in northwest Africa that contains about 30 different metals. Using various spectroscopy techniques and an electron microscope, the researchers documented the signatures left by the organism. Thus, they found that M. sedula  is able to consume extraterrestrial material much faster than it does with terrestrial minerals, resulting in healthier cells.

While terrestrial minerals provide only a few nutrients for the microorganism, “NWA 1172 iron is used as an energy source to meet M. sedula’s bioenergetic needs  as microbes breathe due to iron oxidation,” Milojevic explained. The wide range of metals in NWA 1172 can also be used for other metabolic processes, such as accelerating vital chemical reactions within cells. And because the meteorite is so porous, it can promote M. sedula’s improved growth rate.

That means iron meteorites could have brought more metal elements and phosphorus to Earth, making life’s evolution easier, according to Milojevic. In addition, research may also support the panspermia hypothesis, an idea that cannot yet be substantiated, but it is not ruled out either, as scientists have not yet completely unraveled the origin of life on our planet. And Milojevic is interested in exploring this possibility: To do so, her team plans to “test the survival of  M. sedula  under simulated and real environmental conditions from outer space,” the astrobiologist said. The plan, however, will have to find the funding needed to send the microorganisms into space.
