Heart HealthThe 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.

If you are to successfully lose weight you will likely focus on eating fewer calories and increasing your activity to burn more calories. It’s important that you also address inflammation on your journey to lose weight.
Research on mice has shown a “switch” controlling inflammation in the hypothalamus (region of the brain that regulates energy) becomes “flipped on” in response to high fat diets. It also shows that “overnutrition” (i.e. eating too much) turns on this inflammatory switch.
An increased level of inflammation leads our cells to become resistant to insulin and leptin.
Insulin plays a messenger role in that it tells cells it is time to take in glucose (sugar). If cells become resistant to insulin, they ignore the message that it is time to take in more glucose, glucose is converted to fatty acids, and is stored by our fat cells. If insulin resistance is persistent, eventually the fat cells will no longer respond and increased levels of fatty acids will remain in circulation.
Leptin is a hormone that triggers satiety. This is your body’s way of telling you you’ve had enough to eat. When production of leptin is hindered, we do not feel satisfied and tend to eat more.
As inflammation causes the cells to ignore the messages of insulin and leptin, you are more likely to consume more calories (because you still feel hungry) and potentially store increased levels of fat due to the increased level of circulating fatty acids.
Lose WeightWeight Discrimination – Is your health being affected?
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.
Lose WeightHow does your BMI measure up?
Being overweight increases your risk for heart disease, diabetes, and other illnesses. A quick and easy way to evaluate your risk is to check your body mass index (BMI).
To calculate your BMI all you need to know is your height and weight. Let’s calculate your BMI right now.
BMI = weight (lbs.) divided by height (in.) divided by height (in.) x 703
For example, if you weight is 200 pounds and you are 5’10” (70 in.), your BMI equals 29.
200 divided by 70 divided by 70 x 703 = 28.7

Lose WeightFat and Weight Loss – Do you need to eat fat to lose fat?
When it’s time to lose weight, many of us are trained to think “cut back on fat”. In a previous post – What’s the right amount of fat? – I discussed fat soluble vitamins, how much fat you should include in your daily diet, and some healthy fat sources. Now I want to cover one other important contribution fat makes when it comes to losing weight.
One of the beauties of fat is that it helps us to feel full. Fat is often referred to as the “satiety nutrient.” Have you ever eaten a meal that has been non fat or extremely low in fat? If so, then you might know what I mean. That meal typically doesn’t keep you satisfied for very long which leads to eating more food to get satisfaction. This can result in an overall higher calorie intake!
So for your weight loss efforts, it’s important to curb your appetite by including adequate fat sources with your meals and some snacks! Sixty grams of fat per day can add up quickly so you’ll want to make sure you’re making mindful choices.
Being careful you do not restrict your fat intake too low and include healthy fat sources in your diet everyday is just one of many factors that affect weight loss. To drastically increase your success with losing weight and keeping it off you must wade through all the weight loss information available and sort out what works from what doesn’t. Many methods used to lose weight are ineffective and some may even sabotage your weight loss efforts.

5 Biggest Dieting Myths Revealed
Lose WeightHeart Health – Increase Your Metabolism to Be Heart Healthy
Being overweight is linked to a 45% increased risk of developing heart disease. Shedding extra pounds is not easy, but by boosting your metabolism you increase the calories your burn throughout each day. This will lead to the heart healthy weight loss you desire.
You’ve probably heard the term “metabolism”, but do you really understand what it is and how to use it in your quest for heart health? Let me give you some pointers.
First, the definition of metabolism:
Metabolism is the minimum energy the body needs for basic bodily functions when resting and just awakened. Metabolism is more commonly referred to as the rate at which your body burns calories.
Why should you be concerned about metabolism?
If you boost your metabolism the more calories you burn when at rest and throughout your basic daily activities. This means fewer calories stored as fat and promotion of weight loss. The opposite is true also. If your metabolism drops, the calories you burn drops, and the result is weight gain.
Your muscle mass has the greatest impact on your metabolism. The more muscle you have, the more calories you burn. The less muscle equals the fewer calories. To add another wrench in your weight and heart health struggle, metabolism decreases as you age. The rate of decrease is about 2% every 10 years beginning at age 30. You can counteract this decline by being active and maintaining your muscle mass.
Building an extra 5 pounds of muscle will boost your metabolism by ~100 calories each day.
Tired of changes that don't last?
So, how do you build muscle?
The best way is to start strength training. If this is an area you are unfamiliar with it’s best to work with a trainer for one or two sessions until you feel comfortable. Remember to always consult your MD before starting an exercise program.
You may be thinking, but what about my time on the treadmill? Yes, cardiovascular exercise does build muscle through repetition, but the main purpose of cardiovascular activities is to increase your heart rate to burn calories, not building muscle. Cardiovascular exercise temporarily boosts the rate you burn calories during the activity, but this rate decreases back to your normal level after the activity is complete and your heart rate returns to normal. It does not affect your metabolic rate throughout your day like strength training.
Okay, you’ve decided you need to build some muscle and you’re gung ho to start. Great! But wait one second.
A mistake I frequently see people make is trying to make too many changes at once. If you’re not currently active, suddenly jumping into lifting weights and jogging 5 days a week is not realistic and you set yourself up for failure. You need to take it one step at a time.
Establishing a realistic plan is critical to your success when you strive to boost your metabolism, lose weight, and achieve heart health.
In part 2 you will learn about the “Metabolic Window” and how to maximize your muscle gains through what and when you eat pre/post workout.
