Lose Weight, Control Blood Sugar & Reduce Disease Risk with This Crucial Nutrient


Why Bushmen are Healthier than the Average Westerner.

Dr. Dennis Burkitt, a famous English physician, studied the differences between indigenous African bushmen and their civilized western counterparts. The bushmen appeared free of modern lifes scourges, including heart disease, cancer, diabetes, and obesity.

Dr. Burkitt discovered the average bushman had a stool weight of two pounds, whereas civilized men had a stool weight of only four ounces. What constituted that monumental difference? The amount of fiber they ate.

Today, the average American eats about eight grams of fiber a day, yet researchers determined hunter-gatherer ancestors got about 100 grams of fiber from roots, berries, leaves, and plant foods. That fiber helped our ancestors stay healthy, and getting sufficient amounts can help you maintain peak health today.

Benefits of Fiber

Dietary fiber boasts an impressive resume. Sufficient amounts can actually prevent obesity and chronic disease because fiber slows the rate food enters your bloodstream and increases the speed food exits through the digestive tract, which helps balance your blood sugar. Fiber also helps quickly eliminate toxins from your gut and reduces your appetite.

One study showed how gut bacteria can utilize certain dietary fibers to turn on an anticancer gene and turns off colon cancer. In fact, fiber has been shown to reduce the risk of colon cancer up to one-third and breast cancerby almost 40 percent.

Fiber also lowers cholesterol and reduces the risk of heart disease by as much as 40 percent. If you have diabetes, adding fiber to your diet may even help you use less insulin.

Fiber comes in two flavors: soluble and insoluble. Most of the benefits I described come from soluble fiber, which can also balance hormone levels, remove excess estrogen, make vitamins and minerals, provide food for the colon cells, and much more.

Youll find soluble fiber in fruits, vegetables, beans, nuts, seeds, and most whole grains. Gut bacteria metabolize this soluble fiber, and thats when the benefits start.

That doesnt mean insoluble fiber, found in foods like bran, isnt important. It works as a scouring pad for your intestines, helping you stay regular and reducing constipation and other elimination problems.


The Benefits of Super Fiber

Glucomannan (GM) is a soluble, fermentable, and highly viscous dietary fiber from the root of the elephant yam. The konjac tuber has been used for centuries as an herbal remedy and to make traditional foods such as konjac jelly, tofu, and noodles. More recently, purified konjac flour, or GM, has been used as a food stabilizer, gelling agent, and supplement.

What makes this fiber super? It can absorb up to 50 times its weight in water, making it one of the most viscous dietary fibers known. That means GM can help you shed pounds. In many studies, doses of two to four grams of GM per day resulted in significant weight loss in overweight and obese individuals.

GM works by promoting a sense of fullness, pushing more calories out through your colon rather than letting them be absorbed. GM also lowers your foods energy density. In other words, it bulks up food in your gut, creating a lower calorie content per weight of food you eat.

Since fiber has almost no calories but a lot of weight, adding it to your diet lowers the energy-to-weight ratio of food. Studies show that the weight of food controls your appetite. Fiber increases the foods weight without increasing calories, a critical factor in weight control.

Because of its viscosity, GM leaves your stomach and small bowel slowly. By slowing the rate of food absorption from the gut to the bloodstream, GM reduces the amount of insulin produced after a meal and increases gut hormones like cholecystokinin, further controlling your appetite. And finally, you lose more calories through stool because GM soaks up all those extra calories!

Beyond weight reduction, GM has been studied for its effects on constipation, serum cholesterol, blood glucose, blood pressure, and insulin resistance syndrome.


Nine Strategies to Increase Dietary Fiber

I hope you can understand how crucial dietary fiber is for optimal health and weight. Ideally, you want to get 30 to 50 grams every day. That becomes a breeze when you apply these nine strategies.

  1. Get the flax. Get a coffee grinder just for flax seeds, grind 1/2 cup at a time, and keep in a tightly sealed glass jar in the fridge or freezer. Eat two tablespoons of ground flax seeds a day. Sprinkle on salads, grains, or vegetable dishes or mix in a little unsweetened applesauce.
  2. Load up on legumes. Beans beat out everything else for fiber content!
  3. Bulk up on vegetables. With low levels of calories and high levels of antioxidants and protective phytochemicals, these excellent fiber sources should be heaped on your plate daily.
  4. Go with the grain. Whole grains like brown rice or quinoa (actually a seed) are rich in fiber.
  5. Eat more fruit. Include a few servings of low-sugar fruits to your diet daily. Berries are highest in fiber and other protective phytochemicals.
  6. Go nuts. Include a few handfuls of almonds, walnuts, pecans, or hazelnuts to your diet every day.
  7. Start slowly. Switching abruptly to a high-fiber diet can cause gas and bloating. Increase your fiber intake slowly until you get up to 50 grams a day.
  8. Consider a good fiber supplement. If you have trouble meeting your fiber quota, choose a supplement that contains both soluble and insoluble fiber with no sweeteners or additives.
  9. Choose GM. My favorite fiber is glucomannan (GM) or konjac. Many companies sell it in capsule form. Youll take two to four capsules with a glass of water, 30 to 60 minutes before eating. Dont take any medications within one hour before or two hours after taking it, since fiber may absorb the medication.
