Science Says One Night Of Poor Sleep Equals Six Months On A High-Fat Diet

Science Says One Night Of Poor Sleep Equals Six Months On A High-Fat Diet

You might have read the title of this post and incredulously wondered how on earth one night of poor sleep equals six months on a high-fat diet. Well, it all has to do with our insulin sensitivity. Insulin is a type of hormone that helps keep our blood sugar levels from getting too high (hyperglycemia) or too low (hypoglycemia).

According to a new study conducted by Josiane Broussard, PhD, and colleagues from Cedars-Sinai Medical Center in Los Angeles, one night of bad sleep lowers our body’s sensitivity to insulin in a similar degree as six months on a high-fat diet.

When the body becomes less sensitive to insulin or “insulin resistant,” it’s unable to produce enough insulin to keep blood sugar stable. This may eventually lead to Type 2 diabetes, a disease where there is too much sugar in the blood and the body’s insulin response doesn’t work properly.

Diabetes is associated with a number of serious health complications, including heart disease. The less sensitive you are to the effects of insulin, the more trouble you have absorbing nutrients, digesting carbohydrates, and maintaining a healthy weight.

People who have a hard time maintaining a healthy weight or those with obesity are prone to develop insulin resistance and subsequently diabetes. It’s a terrible, vicious cycle that could all start with one night of poor sleep.

How poor sleep affects insulin sensitivity

In the study led by Dr Broussard, the researchers used a canine model to investigate whether sleep deprivation and high-fat diets affect insulin sensitivity in similar ways. They measured insulin sensitivity in eight male dogs before and after the dogs were fed a high-fat diet for six months. The researchers found that the dogs that were sleep deprived for one night had a decrease of 33 percent in insulin sensitivity. After being fed a high-fat diet, the canines had a 21 percent decrease.

Although this study was done on animals and not humans, it is sill relevant. These types of basic scientific studies involving canines are common and play a critical role in helping to understand the causes and complications of obesity, as well as in identifying processes that may help with its prevention or cure. What this particular study, which was presented on November 5 at The Obesity Society Annual Meeting in Los Angeles, highlights is that pulling all-nighters is not good for the body.

“It is critical for health practitioners to emphasize the importance of sleep to their patients,” said Caroline M. Apovian, MD, FACP, FACN, a Fellow and spokesperson for The Obesity Society. “Many patients understand the importance of a balanced diet, but they might not have a clear idea of how critical sleep is to maintaining equilibrium in the body.”

Ramifications of sleep deprivation

Dr. Broussard noted that, “One night of sleep deprivation and six months of a high-fat diet both reduced insulin sensitivity by a similar degree in canines. However, there was no additive effect of sleep loss and high-fat diet.” Relating these findings to humans, Dr. Broussard added: “This [study] may suggest a similar mechanism by which both insufficient sleep and a high-fat diet induce insulin resistance. It could also mean that after high-fat feeding, insulin sensitivity cannot be reduced further by sleep loss.”

Perhaps referring to numerous other studies (and there have been many this year) that have correlated the ramifications of sleep deprivation on insulin sensitivity, Dr. Broussard said: “Research has shown that sleep deficiency and a high-fat diet both lead to impaired insulin sensitivity, but it was previously unknown which leads to more severe insulin resistance.”

“Our study,” he continued, “suggests that one night of total sleep deprivation may be as detrimental to insulin sensitivity as six months on a high-fat diet. This research demonstrates the importance of adequate sleep in maintaining blood sugar levels and reducing risk for metabolic diseases like obesity and diabetes.”

The takeaway

If there is one thing you can take away from this study, it is that you should take your sleep habits seriously. Get enough sleep each night, 7 to 9 hours at least. And if you think missing one hour or one night of sleep is not a big deal, then think again. Another study published in Diabetes Care showed how seven Type 1 diabetics suffered peripheral insulin resistance after just one night of four hours sleep.

The good news, though, is that some of the damage caused by sleep deprivation (such as decreased insulin sensitivity and other metabolic issues) can be reversed with recovery sleep. So, go to bed a half-hour earlier to pay your sleep debt. And tuck in by a reasonable hour every night for sleep.

How Setting Small Daily Goals Makes You Achieve Big Success

How Setting Small Daily Goals Makes You Achieve Big Success

Successful people “think” success all the time. That is why their goals are firmly lodged in their subconscious.

While most believe that having a long-term goal is crucial to success, successful people understand that without small, daily goals, you will get demotivated easily; success will in turn become hard.

In this article, we will look into the importance of setting daily goals and how to having daily goals that help you achieve success.

How to “think” success with your subconscious

The subconscious is brilliant at prioritizing. It listens to you and gauges from your thoughts what you think is the most important task. This means that what you think about most of the time is what the subconscious will think is the most important thing for you, and will try to find creative solutions.

If you think about problems, the subconscious will try to find you more problems. If you think about solutions, goals and dreams, it will try to make them come true.

But the subconscious goes even further when trying to understand what you think is important; it “listens” to your feelings.

Luckily, it has been proven that a positive thought is over 100 times as positive as a negative thought. This makes it a lot easier to drive positive emotions into your subconscious.

How daily goals keep you positive

It is enough to be positive and keep your thoughts on what you want — and you don’t have to go monitoring your thoughts all the time.

It is enough to imbue your thoughts a few times a day with a powerful positive emotion when thinking about your goals. The more you can do it, the more powerful this exercise will be.

For many, reading their goals or making plans become a chore, something that fills them with negative emotions. This ruins the full potential of these activities; filling yourself with positive emotions while thinking about your goals will make them a lot more powerful.

Over the last several years, I have been taught several exercises that can help you focus more on your goals and spend more time thinking about and feeling about them. What I want you to remember when doing these exercises is to have fun. Never see them as a chore, you are living your goals, it is something to enjoy.

If you don’t feel uplifted at the thought of focusing on your goals, you might as well not do the exercise today. Do it tomorrow instead because it will do more harm than good if you are in the wrong mood when thinking about your goals.

Why positive thoughts inspire you ideas

In my business, I constantly need to come up with new ways to improve efficiency, new ideas to test and new subjects to teach. It takes a lot of creative work — and creative work has always been one of my weaker areas.

Luckily, thanks to all my work with goal setting (and because of my focus on my goals), my subconscious knows these are the things I need the most help with and that they are very important to me.

Every day I get new ideas of things I can try out, products I can create, seminar subjects I can offer, and so on.  All of them aren’t good but when you throw enough “mud against the wall”, something will stick. And that is what my subconscious does — it feeds me idea after idea.

How to set daily goals for yourself

This method is used by countless thousands around the world and for everyone who has tried it, the effects have been incredible:

  1. Each morning, take a pen and a piece of paper and write down your 10 top goals. Don’t look at the day before, just think about what you want to most and write them down.
  2. Remember to write them in the positive present tense and remember to set a deadline for each goal. Just like we did when setting your long term and short term goals. (For example you could set the goal “I make 10,000 dollars per month by the December 31 next year.”)
  3. Do this for all 10 goals.

In the beginning, writing down 10 goals might be difficult. Each day, they might look a bit different and some of the goals you write never come back again.

If you forget a goal, it is because it wasn’t all that important and something more important has taken its place.

What difference does it make?

By starting your day setting your 10 top goals, you jump-start your creativity — which will motivate you for the rest of the day. You will have programmed yourself to focus on your goals and to move towards them and their completion.

What will happen to you?

If you do this, you will start to realize what is important to you. You’ll see what goals keep surfacing and what goals vanish.

You will know what you want and you will find yourself presented with opportunities that you haven’t noticed before.

You will be more creative in finding ideas and chances to make your dreams reality.

The bottom line

Having goals on a daily basis can change your life for the better. It will help you keep moving faster and faster towards your goals and dreams.

So now set your goals and make having daily goals your good habit:

  1. Buy a notebook and a pen at your local bookstore.
  2. Start writing down 10 goals every morning, without looking at the day before.
  3. Take advantage of the opportunities that come your way and capitalize on them.
What’s next after setting your goals? While your routine is the key to achieving your goals, you can take these 6 simple steps to make progress towards achieving goals.
