Belly fat, also called abdominal or visceral adipose tissue, is associated with many aging health problems including metabolic syndrome.
A new animal study compared animals on a regular diet where they were allowed as much food as they wanted; animals on a calorie restricted, optimal nutrition diet; and animals who had their belly fat surgically removed and then were allowed as much food as they wanted.
As expected, the calorie restricted animals had the greatest mean and maximum lifespan.
While removal of the belly fat increased maximum lifespan only slightly, there was significant increase in mean lifespan compared to the regular diet animals (Muzumdar R, Visceral adipose tissue modulates mammalian longevity, Aging Cell, June 2008.
Both green tea, and certain diets have shown improvements in belly fat, while at the same time providing low calorie selections for calorie control.
Green Tea Catechins And Belly Fat News: Lose That Belly Fat?
Catechins from green tea are polyphenol antioxidants that include the powerful EGCG.
While green tea has been shown to improve blood fats like cholesterol levels, a new study examines how green tea catechins can improve other cardiovascular risk factors including belly fat.
The study took place during a 12-week multicenter trial with 240 Japanese women and men who had abdominal obesity or belly fat.
The subjects were given green tea with high catechins (583 mg.) or low catechins (96 mg.) daily under double-blind conditions where neither the doctor nor the subject knew which tea they received.
Compared to the low catechin group, the high catechin group lost more body weight, body fat mass, subcutaneous fat, and belly fat. They lost more distance around their waist and hips. They lowered their body mass index (BMI) more. Their blood pressure dropped more among those who started with systolic blood pressure higher than 130 mm Hg. Their LDL or bad cholesterol decreased more.
There were no side effects for either group (Nagao T, A green tea extract high in catechins reduces body fat and cardiovascular risks in humans. Obesity-Silver Spring, June 2007).

Brain and Belly Fat News: Will Fat Bellies Make You Crazy?
Belly fat is proving to be an independent risk factor for many life-threatening diseases. In other words, it's not only being overweight, but also where the extra fat is deposited that is dangerous.
Now a new study shows that belly fat in midlife is associated with an increased risk of developing dementia later.
Researchers comparing medical records of 6583 people beginning in 1964 and following them up to 2008 (average follow-up was 36 years). For obese people with abdominal fat, the risk of dementia was 3.6 times greater than for people of normal weight and no belly fat.
Overweight people with abdominal fat had an increased risk that was 2.3 times greater than normal.
Thus belly fat either doubled or quadrupled the risk of dementia depending on how much extra fat people carried.
What about normal weight people with a little belly fat?
Their risk of dementia increased 1.89 times, also almost doubling (Whitmer,R, Neurology, March 2008).
How do you get rid of belly fat? Everyone recommends improving your diet and exercise.
Oats And Belly Fat News: Whole Grains Blast Belly Fat
Did your grandparents tell you that your morning bowl of oatmeal would stick to your ribs?
Mine did.
I still don't know if that's true, but now a study shows that your morning oatmeal could help you lose belly fat.
Researchers tested obese adults with metabolic syndrome, age 20 to 65 years old, during a 12 week diet. Divided into two groups, both received the same information on weight loss and exercise. Dietary recommendations included five servings daily of fruits and vegetables, three low dairy, and two servings of lean meat daily. One group was instructed to eat whole grains only for their grain servings, and the other group was instructed to eat refined grains only.
Researchers measured weight, biomarkers, and belly fat.
While both groups lost approximately the same amount of weight, the whole grain group lost significantly more weight from the abdominal area--their belly fat.
The whole grain group also showed a 38% decrease in C-reactive protein, a protein biomarker associated with increased risk of diabetes, high blood pressure, and heart disease (Katcher HI, American Journal Of Clinical Nutrition, 2008).
Researchers stated that this amount of C-reactive protein reduction was similar to reductions seen with statin drugs.
Whole grain foods include oatmeal (thank you, grandparents!), whole grain cereal, whole grain breads (if listed as the first ingredient), brown or black rice, wild rice, buckwheat, whole wheat pastas, and other specialty grains like kamut and spelt.

Calories And Belly Fat News: Belly Fat Is Not Invincible
Calorie restriction with optimal nutrition is used in laboratories to create very large increases in average life span and maximum life span with a variety of species.
A new study using mice shows a sequence of improvements that helps create this longevity increase.
Researchers found there were substantial changes in the liver and pancreas within the first week of dietary restriction. Insulin dropped 50% and the liver PPARgamma mRNA fell to 13% of baseline.
Belly fat and other subcutaneous adipose tissue began to change after four weeks (Mulligan JD, Experimental Gerontology, 2007).
Tumor formation from precancerous conditions can decrease after eight weeks on calorie restriction.
These results are with mice, a species that is considerably more short-lived than humans. But the results confirm the consistent progression of anti-aging health benefits from calorie restriction without malnutrition.
Diabetics may want to discuss dietary energy/calorie restriction for insulin improvements with their physicians.
Your Brain And Belly Fat News: Big Bellies Bad For Men's Brains
A study from Finland tracked the total health of 49,996 men and women, aged 25 to 74. All participants were free of stroke and heart disease at the beginning of the study.
During almost 20 years of follow-up, 3228 people had strokes.
After comparing the stroke patients with a matched sample of men and women, the results were that BMI (body mass index or overweight) was related to strokes for both men and women.
But increased abdominal fat or belly fat was only associated with increased strokes for men, not for women (Hu G, Archives Internal Medicine, 2007).
Weight And Belly Fat News: English Belly Fat Is Expanding.
The National Health Survey for England has found that belly fat or abdominal fat has increased from 26.2% in 1993 to 39.0% in 2003 for men and from 32.4% in 1993 to 47.0% in 2003 for women.
Generalized obesity has also increased in England, now affecting over 25% of their population.
Both men and women with abdominal obesity showed a dramatically higher risk for diabetes, high blood pressure, and heart disease. By 2003, the risk of diabetes had more than doubled for those with abdominal fat.
Public health officials are urging immediate action to prevent epidemic levels of life-threatening consequences for obese people in the near future (Hirani V, Public Health Nutrition, 2007).
While weight loss is always based in calories in and calories out, you can learn about how green tea may help protect against belly fat here.
And remember, a nice cup of green tea is one of the best substitute behaviors on the planet!
Heart And Belly Fat News: Big Bellies And Artery Blockages
While being overweight increases the risk of many diseases, some kinds of overweight are worse than others.
In some ways, belly fat, also called abdominal fat, stomach fat, pot belly, or apple shape, might be more dangerous than your total weight.
In a new study, multi-ethnic adults from the Dallas Heart Study were checked for waist hip ratio (WHR), body mass index (BMI), waist circumference, and the development of atherosclerosis. Using MRI and EBCT, researchers measured atherosclerosis by the presence of calcium deposits in the arteries and heart.
The most significant predictor of atherosclerosis was surprisingly the waist hip ratio, that is, abdominal or belly fat (See R, Journal American College Cardiology, 2007).
