The Connection Between Sleep Deprivation, Weight Gain, and Heart Disease
A lack of sleep can directly impact your weight and overall health.
Studies have shown a lack of sleep promotes the expression of a gene linked to obesity. Both sleeping too little (less than 5-6 hours per night) and too much (greater than 9-10 hours per night) are associated with weight gain.
Researchers also propose a lack of sleep can lead to a vicious cycle, meaning poor sleep equals weight gain equals conditions that interfere with sleep which equals continued sleep deprivation.
Appetite
Sleep quality and quantity impact the appetite regulation hormone ghrelin. Ghrelin levels decrease after a meal and increase between meals.
Leptin is another hormone that reduces feelings of hunger. Leptin levels increase during the day and peak at night.
Adipose tissue secretes leptin while the stomach secretes ghrelin.
Sleep deprivation has been shown to increase the ratio of ghrelin to leptin leading to increased appetite and specifically increased carbohydrate cravings. Many studies have shown a lack of sleep leads to increased caloric intake throughout the day.

There are times when it is normal for the heart to beat harder, such as if you are out hiking and encounter a bear. Your blood pressure will jump so larger levels of oxygenated, nutrient-rich blood is sent through your system and you are able to react. All part of the flight or fight response.
When you are diagnosed with high blood pressure your blood pressure is not just high for limited periods of time. It is consistently elevated. This means the heart is constantly working harder than it should.
Here are 7 reasons your heart may be dealing with this increased workload:
1. Atherosclerosis (narrowing of the arteries) – This may be caused by cholesterol deposits along arterial walls resulting in plaque buildup. Fibrosis or endothelial dysfunction may also result in narrower arteries.
When arteries narrow the heart has to pump harder (exert more force) to move blood throughout the system.

Purdue University researchers conducted a study to evaluate the impact of weight discrimination on health declines for obese individuals. The purpose of the study was to show that extra pounds alone don’t account for all the health problems and overweight or obese individual lives with. It is theorized that individuals with a higher body mass index are more likely to feel discriminated against due to their weight. The more an individual believes they are a victim of weight discrimination the more their health is impacted.
Obesity Rates Have Stabilized
Researchers periodically evaluate data from NHANES (National Healthy and Nutrition Examination Survey). Recently rates of obesity were compared over the past 50 years.
Between 1960-1980 the number of adults who were obese stayed relatively stable. Between 1976-1980 and 1988-1994 data the number of obese adults in the US increased 8 percentage points. Then between 1999-2000 data reported further increases in the number of U.S. obese adults.
Well, the latest research has been analyzed again and the good news is that the percentage of obese women did not significantly increase between 1999 and 2008.
If obesity is not longer increasing, that is great news; but the fact that 68% of U.S. adults are overweight or obese and 32% of U.S. school children are above the 85th percentile BMI-for-age leaves plenty of room for concern.
It’s still critical that individuals who are overweight or obese take steps to lose the extra pounds. Obesity is a major health risk increasing risk for many diseases, including heart disease and cancer.
Overweight is defined as a body mass index (BMI) between 25-29.9.
Obesity is defined as a body mass index above 30.0.
Don’t know where you fall? Here’s a how to calculate your BMI:
Weight divided by height divided by height x 703 = BMI
Here’s an example:
Height = 64 inches
Weight = 150 pounds
150 divided by 64 divided by 64 x 703 = 25.7 (overweight)
The first step is to evaluate your situation and outline a plan of action. A Mini Diet Makeover will complete this for you – https://www.lisanelsonrd.com/minidietmakeover.html.

Firefighters Health – Alarming rates of overweight and obesity
A study published in the journal of Obesity examined the health and fitness of new recruits for Boston-area emergency services. The study included 370 firefighter, emergency medical technician, and paramedic recruits with an average age of 26 years-old between October 2004 and June 2007. Out of the 370 recruits, 1 out of 5 were of normal weight, ~44% were overweight, and 33% were obese. The weight of the young recruits is significantly higher than older veteran firefighters from the 1980’s and 1990’s.
All recruits must pass a physical fitness treadmill test, which 93% of the overweight recruits did pass; however 42% of the obese participants failed the standard fitness test. Evidence that it isn’t muscle mass causing BMI scores to be high, which is a common misconception in the emergency responder community. Significant findings due to the increasing death rate in emergency responders due to cardiovascular disease and musculoskeletal injuries. It’s critical for emergency responders to be fit since they are responding to life-and-death situations. Obesity can lead to sleep apnea, which in turn results in drowsy, less alert emergency personnel. Enforcing fitness guidelines and making BMI a vital sign during medical examinations is a step towards improving the health of our emergency service recruits and veterans.

Top 5 Key Strategies to Lose Weight Permanently
Heart Disease – Reduce Heart Disease by Eating More Whole Grains
Your risk of heart failure is increased by a variety of factors, such as coronary artery disease, obesity, diabetes, insulin resistance, and hypertension. What you eat has a major impact on these risk factors.
A new study was recently released in the Journal of the American Dietetic Association that supports eating whole grains to reduce heart disease risk.
The 13 year study evaluated the association between seven different food categories (fruits/vegetables, whole grains, eggs, high-fat dairy, nuts, fish, and red meat) and heart failure risk in over 14,000 adults. During the study, 1,140 adults were hospitalized for heart failure. The study found that heart failure risk was significantly reduced in individuals with a high whole grain intake. Heart failure risk was significantly higher in individuals with increased intake of eggs and high-fat dairy.
A much smaller scale survey of 800 American adults shows promising changes. The first diet and exercise survey conducted by the American Dietetic Association was in 1991 and the most recent in 2002. The goal of the survey is to measure current attitudes and behaviors toward diet and health and identify behavior changes over time.
Findings of the 2008 survey show that consumption of whole grains, vegetables, and fruit has increased, while trans fat, beef, pork, and dairy consumption has decreased.
Increased in the past 5 years:
Whole grains – 56%
Vegetables – 50%
Fruits – 48%
Low-fat foods – 48%
Omega 3 fatty acids – 38%
Decreased in the past 5 years:
Trans fat – reduced 56%
Beef – reduced 41%
Port – reduced 33%
Dairy – reduced 23%
Low-sugar foods – reduced 20%
The survey divided participants into three groups based on diet and exercise habits. Here are the divisions:
I’m already doing it – 43% (5% increase from 2002)
I know I should – 38% (8% increase from 2002)
Don’t bother me – 19% (13% decrease from 2002)
So, overall it looks like American’s are wising up. However, what’s important is you. Where do you fall? Are you increasing your whole grain intake, eating more fruits/veggies, and cutting back on trans fats? Are you doing what you need to, in order to reduce heart failure risk?
