Waist circumference has a direct relationship to high blood pressure and lipid (cholesterol) levels.
A study published in the Archives of Pediatrics & Adolescent Medicine found the greater the Waist-to-Height Ratio the worse the lipid profile and hypertension in adolescents.
This particular study evaluated 4,104 ninth-grade students between the ages of 14 and 15 years-old during the 2009 – 2012 school year. Body mass index was used to classify waist measurements.
The greater the waist-to-height ratio, the greater the risk for poor lipid profiles and high blood pressure compared to those with normal body mass indexes and waist-to-height ratios.

Here are 3 foods containing nutrients that promote a lower blood pressure:
1. Sweet potatoes
Sweet potatoes are a rick source of potassium. Adequate potassium intake is essential to balance sodium and promote a lower blood pressure. The recommended ratio of potassium to sodium is 5:1. Increasing potassium intake can result in a blood pressure reduction of ~5 mm Hg systolic and ~2.5 mm Hg diastolic.
Do you struggle with extra fat around your midsection? Excess abdominal fat is not only visually unappealing to some, but it increases your heart disease risk.
What causes abdominal obesity?
There are many different reasons your body likes to store fat in the abdomen. I want to discuss one possibility – cortisol.
Cortisol is a hormone made by the adrenal glands in the kidney. Cortisol levels are highest in the morning. Through gluconeogeneis (term for glucose production), cortisol breaks down muscle to provide the body with needed glucose for energy needs. Cortisol also relocates fat cell deposits into the visceral cavities of the abdomen.When we are confronted with stress our body’s initial response is “fight or flight”. When we go into “fight” mode our body releases the hormone norepinephrine. When we respond with “flight” (or anxiety) our body releases epinephrine. If the stressful situation is long term and you begin to feel distressed and defeated, the hypothalamus in the brain becomes involved, eventually leading to the release of cortisol from the adrenal gland in the kidney.
Why is “fight or flight” important to understand?
Your perception of an event can determine your body’s physical response. Do you feel stressed, but challenged by an obstacle or do you feel overwhelmed and out of control? If you feel challenged and “fight” your body responds with an accelerated heart rate that increases the release of fatty acids into circulation. If you feel out of control and defeated (“flight”), the body increases fat formation (lipogenesis), breakdowns tissue (muscle), suppresses the immune system, and increases visceral fat deposits.
What is visceral fat?
Visceral fat is the fat around and between your organs. Subcutaneous fat is the fat layer beneath your skin.
Excess visceral fat leads to the “beer belly” effect (also referred to as the “apple” shape). Visceral fat is connected to insulin resistance and glucose intolerance (linked to diabetes), high cholesterol, high blood pressure, and heart disease.
Are you at risk?
Get out a tape measure.
Wrap the tape measure around your abdomen at the level of your navel (belly button). Make sure the tape measure is level all the way around (you may need extra hands). Resist the temptation to cinch in the tape measure for a lower number, instead hold the tape measure lightly against your skin.
Men – A waist measurement of 40 inches (102 cm) or greater equal’s abdominal obesity.
Women – A waist measurement of 35 inches (88 cm) or greater equal’s abdominal obesity.
How to reduce stress for minimal impact on abdominal fat and heart disease risk?
Stress is a part of living, but you can take steps to reduce your stress levels.
Physical activity, especially aerobic activity, is a great stress management tool. Activity releases the “feel good” hormone serotonin to help combat the negative effects of long term stress. As an added bonus, you burn calories to shed the extra layer of fat.
p>Additional interventions to reduce stress include deep breathing, progressive relaxation, meditation, and visualization. Don’t be afraid to step out of your comfort zone and try something new that may be effective at reducing your stress levels. Getting enough sleep and making healthy food choices are two additional steps to promote stress management.

I enjoy the show The Biggest Loser. On one of the episodes this season they had an individual from Prevention magazine share some tips based on the “Flat Belly” diet. I was very excited because it sounded like a link had been found between the Mediterranean diet and reduced abdominal obesity. Hence, the reason for this article!
The Mediterranean diet contains an increased level of monounsaturated fat compared to the typical American diet. Monounsaturated fat is a type of heart healthy unsaturated fat. One of the best monounsaturated fat sources is olive oil. I went to work researching to find scientific evidence to support a link between a diet high in monounsaturated fat and reduced belly fat.
Here’s the main study supporting the connection between decreased abdominal obesity and monounsaturated fats.
Study: Published in the Diabetes Care back in 2007 by J.A. Paniagua, MD, PHD, A. Gallego de la Sacristana, MD, I. Romero, PHD, A. Vidal-Puig, MD, PHD, J.M. Latre, MD, PHD, E. Sanchez, MD, P. Perez-Martinez, MD, PHD, J. Lopez-Miranda, MD, PHD and F. Perez-Jimenez, MD, PHD
Monounsaturated Fat-Rich Diet Prevents Central Body Fat Distribution and Decreases Postprandial Adiponectin Expression Induced by a Carbohydrate-Rich Diet in Insulin-Resistant Subjects
The purpose of this study was to show that central obesity is linked with insulin resistance (when the body does not respond normally to insulin) and studied the effect of three different diets with the same level of calories on fat distribution, insulin sensitivity, and peripheral adiponectin (fat hormone) gene expression. The study included 11 individuals that were considered insulin resistant. Everyone in the study spent 28 days on each of the following diets: 1. diet enriched in saturated fat, 2. diet rich in monounsaturated fat, 3. diet rich in carbohydrates.
The study found weight, body composition, and metabolism unchanged during all three diets. On a high carbohydrate diet, fat tended to be redistributed to the abdominal area versus the high fat diets.
There have been many studies conducted on this theory, but the results are all conflicting.
Expert Opinion
1. Not enough evidence to support a connection.
This was a fairly small study of only eleven individuals. A study on 62 women published in the Journal of Nutrition in 2004 did not find a link between a diet high in monounsaturated fat and changed body fat distribution. There needs to be more large scale studies that conclusively establish a link before we can jump on the bandwagon.
2. Follow a Mediterranean Diet anyway!
Whether or not a Mediterranean Diet targets belly fat or not, the benefits of this type of diet are well known when it comes to heart health and weight loss.
Those that follow a Mediterranean Diet have a reduced risk of developing heart disease and dying from a heart attack. Even those that have survived a heart attack and lived to adopt the Mediterranean Diet significantly reduce their risk of a second heart attack and other complications.
Also, those that follow the Mediterranean diet have increased satiety (feelings of fullness) due to the adequate fat and fiber content. This means a decreased urge to overeat which promotes weight loss.
Characteristics common to a Mediterranean Diet include:
Consume high intake of fruits and vegetables
Select whole grains
Consume healthy fats (canola and olive oil)
Eat nuts in moderation
Low red wine consumption
Limit eggs to less than 4 times per week
Consume little red meat
Eat fish regularly
If you adopt this style of eating now and some conclusive evidence comes out in the future supporting a link with decreased belly fat, it won’t matter. You’ll already be lean with a healthy heart!
