Do High-Fat Foods Disrupt Your Body Clock?

[Guest guest]

Hi,

Here are 2 articles that DR Mercola talks about.

This article really should have a subject title as to say:

" Keeping the light on while you sleep disturbs your sleeping patterns. "

Or " Dont eat after the sun goes down "

I must have all lights off when falling asleep, I am really fanatic

about that, no TV on while falling asleep, I really dont like the

digital light from the clock facing me, I cover it with a bottle of

lotion.

Also, I stop eating at 6pm, that is my cut off time, and this really

helps with the dieting and keeping the weight off.

For some reason the body's metabolism slows down when the sun goes

down. This to me is always been apparent, even as a young teenager to

me.

And I sleep better when my stomach isnt full! and no heart heartburn.

Ok heres the articles:

Do High-Fat Foods Disrupt Your Body Clock?

http://articles.mercola.com/sites/articles/archive/2007/12/01/do-high-

fat-foods-disrupt-your-body-clock.aspx

Mice that ate a high-fat diet gained weight and experienced a

disruption in their circadian clocks, which regulate metabolic

functions such as when they go to sleep, wake up and become hungry.

The disruption threw off the timing of the animals' internal signals,

including appetite control. As a result, the mice ate extra calories

during the time when they would have otherwise been asleep or resting.

For humans, this would be the equivalent of raiding the refrigerator in

the middle of the night.

The high-fat diet and resulting weight gain also triggered diminished

expression of genes that encode the clock in the brain and in

peripheral tissues.

The findings suggest that changes in metabolic state that occur with

obesity and diabetes affect not only circadian rhythms of behavior but

also physiology.

Past studies have found that a misaligned body clock can throw off your

metabolism, and increase your risk of obesity and diabetes.

This represents a " vicious loop, " according to researchers, because

once weight is gained, your internal clock is disrupted, and a

disrupted clock makes the original problem worse.

" Timing and metabolism evolved together and are almost a conjoined

system, " said one of the study's authors Joe Bass, M.D., assistant

professor of medicine and neurobiology and physiology at Northwestern

and head of the division of endocrinology and metabolism at ENH. " If we

perturb the delicate balance between the two, we see deleterious

effects. "

Dr. Mercola's Comments:

The problem with virtually all diet studies like the one above is that

they tend to ignore a profound foundational element of human

physiology. The very foundation of their study presumes that all humans

have similar food requirements.

If you have been reading this site for a while you will know that

nothing could be further from the truth. Some were designed to eat high-

fat, high-protein diets while others thrive on low-fat, low-protein

diets.

Analysis of these premises becomes a bit more cloudy when you switch to

animal models, as they tend to have a more homogenous genetic

background, especially the animals that are bred for scientific

experiments. The researchers are assuming they can generalize their

findings to humans, but for this type of research I do not believe the

science supports it.

So Just What Can You Do to Improve Your Sleep Cycle?

Your sleep/wake cycle, regulated by your circadian rhythm (or your

body's internal clock), has evolved over many years. If you violate

these very powerful biorhythms, you are asking for trouble.

What may surprise you is that your body has many internal clocks -- in

your brain, lungs, liver, heart and even your skeletal muscles -- and

they all work to keep your body running smoothly by controlling

temperature and the release of hormones.

Your heart rate, body temperature and hormone production vary with your

personal internal clock. This, in turn, influences such things as:

The easiest time to detect disease in your body

The times when you'll be less sensitive to pain

The times when you'll be more productive at work

However, this is a very delicate system, and it is easily thrown off

kilter.

Does your diet also impact your internal clock? Definitely.

What you eat sends your body signals about when to wake up and go to

sleep. Your meals, which are typically at relatively consistent times

throughout the day, also help to reinforce other time-setting

activities.

In terms of foods themselves, protein-rich foods help your body to

produce chemicals that tell you to wake up. High-carbohydrate foods,

meanwhile, produce chemicals that tell you to go to sleep.

This is why jet lag, which occurs when your body's inner clock is out

of sync with the time cues it receives from your environment, can be

significantly reduced by eating the right foods.

Another questionable aspect of the study is the fact that the mice were

kept in darkness for the entire duration.

Changes in light dramatically impact your health and your biological

clock. Mice do not typically live in complete darkness, so I question

whether this impacted the results.

How to Keep Your Circadian Rhythm in Balance

Aside from being linked to obesity and diabetes, a disrupted circadian

rhythm may influence cancer progression through shifts in hormones like

melatonin, which your brain makes during sleep. So it's crucial that

you support your body's natural sleep/wake cycle.

The following tips will help to keep your body's internal clock running

smoothly:

Sleep in total darkness!! If there is even the tiniest bit of light in

your room it can disrupt your circadian rhythm and your pineal gland's

production of the hormones melatonin and serotonin.

This is the " hidden " secret that most people tend to ignore. This was

recently brought to my attention when the highly knowledgeable

chiropractor who works in my clinic, Dr. Lloyd Fielder, told me that he

never fully appreciated the power of this intervention. He recently

installed black out drapes in his bedroom and was shocked at how much

better he felt -- it radically improved the quality of his sleep.

So do yourself a favor this holiday season and purchase yourself some

black out drapes. You will be shocked at how much better you feel, and

you will also radically lower your risk of cancer.

Sleep when it's dark outside and get up when the sun comes up. This is

another largely ignored -- yet vitally important -- health principle.

You should at least strive to sleep between 10 p.m. and 6 a.m. This

means you should be in bed, with the lights out, by 10 p.m. and be up

by 6 a.m. If this is difficult for you, keep in mind that people

naturally followed this pattern before the advent of electricity. This

has been an important part of Ayurvedic medicine for over 5,000 years.

Avoid working the night shift. It's been linked to significantly lower

levels of serotonin, which may cause sleep problems, anger, depression

and anxiety. If you currently work the night shift, I would strongly

suggest trying to switch your hours, or at the very least not keeping

the night shift for longer than a couple of months at a time (and

giving your body a chance to readjust in between).
