Blueberries May Help Banish Belly Fat

You've probably heard me rant and rave about blueberries. I eat them about six out of seven days a week, I gave them a "star" in my book "The 150 Healthiest Foods on Earth", and I've spoken at length about their high antioxidant content, their low sugar content, and their ability to boost memory.

Well, get ready for some hot news: Blueberries may also help banish belly fat.

A new study by researcher E. Mitchell Seymour, MS, of the University of Michigan shows that rats that ate a diet high in blueberries lost abdominal fat- the kind linked to increased waist size and increased risk for diabetes and heart disease. This happened even when the rats ate a high-fat diet. As an extra added bonus, the blueberry eating rats also had improved glucose control (meaning their blood sugar was more stable).

The researchers suggest that blueberries- with their high antioxidant content- may somehow alter the way the body stores and processes sugar, great news for those at risk for both heart disease and diabetes. "Our findings in regard to blueberries show the naturally occurring chemicals they contain, such as anthocyanins, show promise in mitigating these health conditions," said researcher Steven Bolling, MD, of the University of Michigan,

In the current study- presented at Experimental Biology 2009- rats were bred to become obese were fed either a low-fat diet or a high-carb diet, both of which were enriched with whole blueberry powder (about 2% of their total caloric intake).

After three months the rats fed the blueberries had improved glucose control and improved insulin sensitivity. Better glucose control and improved insulin sensitivity are both strongly related to lowering the risk for diabetes.

I find blueberries one of the easiest foods to incorporate into your diet. In season or not, you can always get them frozen, and I like to eat them right out of the freezer (mixed with frozen cherries). I put some FACE 2% yogurt on them, sprinkle with some slivered almonds, flaked unsweetened coconut and some probiotic powder and have them as a nightly "dessert". It's the ultimate "anti-aging" treat!

Withdrawn: Advice on Low-Fat diets for Obesity!

Have you heard that a low-fat diet is the way to go for weight loss?

Of course you have. Who hasn't? And like much "conventional" advice, it's turning out to be bogus.

Recently, researchers combed through hundreds of previously published studies that investigated low-fat diets in comparison to other weight loss strategies. They looked at the Cochrane Controlled Trials Registry, MEDLINE, and EMBASE, all sources of rigorously controlled published trials. They were interested in the ability of people to actually sustain weight loss over a long period of time, so they investigated the studies in which people were given specific dietary advice (like eat a low-fat diet, or reduce calories). Three independent reviewers poured over the studies that met the criteria for inclusion.

Guess what they concluded?

"Fat-restricted diets are no better than calorie restricted diets in achieving long term weight loss in overweight or obese people".

The title of their research paper- published in the prestigious Cochrane Database System Review was "Withdrawn: Advice on Low-Fat Diets for Obesity".

That kind of says it all, doesn't it?

You can lose weight on a low-fat diet, you can lose weight on a low-carb diet, and you can lose weight on a calorie-restricted diet. The choice should be based on what makes you feel better, reduces your cravings and increases your energy.

There's absolutely no advantage of a low-fat approach over any other, and in fact, there may be some disadvantages.

One disadvantage of a low-fat approach is that people eat more processed carbohydrates when they reduce fat too much. Another may be lower intake of valuable and healthy fats like omega-3's.

And a third disadvantage of low-fat diets is the constant cravings that frequently accompany them! I've never heard of anyone binging on buttered broccoli and steak, but I've sure heard of binging on cereal and bread!
