Why am I always hungry? Are women biologically hungrier than men?
Do you frequently ask yourself – why am I always hungry?
I just read an interesting study I want to share with you. This research was done at Brookhaven National Laboratory. Thirteen men women and 10 men were asked about their favorite foods, taught a cognitive inhibition technique, and then were asked to fast overnight. The next day they received brain scans as they were presented their favorite foods. Results showed all participants indicated the cognitive-inhibition technique helped reduce their level of hunger. Interestingly, only men’s brains showed a decrease in hunger signals. Even though women stated they were less hungry, the brain scans showed their brains firing away signals to eat.
Maybe this is one reason the incidence of obesity is higher for women. It’s speculated that the difference is biological and women are programmed to eat whenever food is available as part of the ingrained need to provide nutrition to children.

Weight Loss – Are low carb diets affecting your brain function?
Some studies are being conducted evaluating the effects of low carb diets, such as the Atkins diet, on cognitive ability. Brain function on a low carb diet may be impaired because glucose is the nutrient used by the brain for energy and the brain is not capable of storing glucose, but is depended on the bodies production of this nutrient.
Many low carb diets restrict intake to as little as 20 grams per day, while the RDA for carbs is at least 130 grams (taking into account the brains energy needs).
One study compared long and short term memory, spatial memory, and visual attention of women prior to beginning a low carb diet, post low carb diet, and after reintroduction of carbs. Those following a low carb diet had a gradual decline in memory performance and slower reaction time on all tests. Interestingly, attention span was improved on the low carb diet.
Fortunately, memory skills and scores returned to normal after carbohydrates were reintroduced.

Weight Loss – Have you tried Stevia, the new zero-calorie sweetener?
Stevia has been approved by the FDA (U.S. Food and Drug Administration) as “generally recognized as safe”, meaning it can be marketed as a dietary supplement and added to food and drink products.
Stevia is using the label “natural” since it’s derived from the leaf of the stevia plant. This may be hard to accept due to the “bad rap” many artificial sweeteners have. Currently there are 5 artificial sweeteners approved by the FDA – aspartame (Nutrasweet, Equal), saccharin (Sweet’N Low), acesulfame-K (Sunett, Sweet One), neotame (made by NutraSweet), and sucralose (Splenda). Even though these sweeteners have received FDA approval, many question the safety and research studies are ongoing.
On the plus side for Stevia, it actually comes from a plant versus a lab. Stevia is a highly refined part of the plant called rebiana or Reb-A. This is the sweetest, purest part of the plant. A company out of Malaysia, PureCircle, claims to be the world’s largest supplier of Reb-A and has worked with a Swiss company to make the bitter, licorice flavor more palatable.
Regardless, we’ll soon be presented with many products containing Stevia in the near future. PepsiCo and Coca-Cola are launching new lines of stevia sweetened products along with producers of other food products, including baked goods and breakfast cereals.

Weight Loss – How Stress and Cortisol Affect Weight Loss
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.

Heart Health and Weight Loss – How much fat do you need?
I want to talk about the fat in your diet. When it comes time to lose weight one of the first steps is to switch to a low fat diet. I want to caution you not to drop your fat intake too low. Yes, you need to watch the fat calories, but some fat is needed everyday for optimal health.
Fat is an essential component of a healthy diet providing energy and the fat soluble vitamins A, D, E, and K. Some types of fat even reduce your risk for certain chronic diseases, such as heart disease.
What’s important is the amount and type of fat. I recommend restricting fat intake to ~30% of your total daily calories. This would mean if you are consuming 1500 calories per day, 450 calories or 50 grams would come from fat sources.
Now, you need to make sure these fat sources are healthy. Here are examples of healthy fat sources to include in your diet in moderation:
Olive oil
Avocados
Seeds
Nuts
Peanut butter
Fish
Some fat in your diet actually promotes weight loss by helping you feel full longer, decreasing your likelihood to snack too much and overeat!
