Have we known that carbohydrate restriction fights cancer for nearly 100 years? One of the defining characteristics of cancer cells is the inefficient metabolism of glucose to lactate even in the presence of oxygen. This aerobic glycloysis (the breakdown of glucose by enzymes without oxygen) is known as the Warburg effect and has been known since the 1920s. Yet, little has been done to utilize this fact in helping to prevent or treat cancer.
The National Cancer Institute predicts that “in 2018, an estimated 1,735,350 new cases of cancer will be diagnosed in the United States and 609,640 people will die from the disease.”
In spite of all the cancer research, the number of people getting cancer in on the increase.

Shouldn’t we limit the primary nutrient of cancer cells as a means of fighting cancer?
Sugar is a Key Nutrient for Cancer Cells
Your body typically processes glucose (a sugar from carbohydrates) in two ways. Each way produces ATP molecules (adenosine 5′-triphosphate, the energy source for all cells of the body). Continue reading →
You’ve gone to the gym to do aerobics. You’ve done crunches and tried hours of spinning classes. You’ve done resistance exercises to build muscle to raise your metabolism.
You’ve tried the Zone diet, the South Beach diet, the Mediterranean diet, and even the Weight Watchers diet.
And you’re still ready to shout: Why Can’t I Lose Weight?
Missing Key to Weight Loss
You probably know that to lose weight, especially to lose fat, you need to cut back on calories. Calories represent the energy value of foods. Now, the cells of your body get their energy from these sources: Continue reading →
Eat healthy foods. This means plenty of fruits and vegetables, avoid processed meats and, if you must drink alcohol, drink in moderation.
Avoid obesity. Maintain a healthy weight and get plenty of exercise.
Avoid overexposure to the sun. Skin cancer is a common form of cancer.
Avoid carcinogens. These include viruses, bacteria, and parasites as well as air, water and soil pollution.
Avoid a compromised immune system.
Some Cancer Prevention Research to Keep in Mind
Eat Your Veggies
One study published in the journal Epidemiology studied how fruits and vegetables affected rates of cancer of the colon, rectum, and breast. The authors indicated that carotenoids, flavonoids, phenols, isothiocynates, fiber, and vitamins C and E could have anti-carcinogenic effects.
They found that raw carrots were the only vegetable that lowered cancer risks by 20% or more for all three types of cancer. They also found that apples, pears, and kiwi were associated with at least a 5% risk reduction for all three cancer types.
Overall high intake of raw vegetables lowered risks by 20% for colon cancer, 18% for cancer of the rectum, and 15% for breast cancer.
Cooked vegetables also reduced risks by 28% for colon cancer, 20% for cancer of the rectum, and 4% for breast cancer.
Watch Out for Sugar
Cancer cells love glucose (blood sugar). They take in and metabolize glucose faster than normal cells.
This fact allows positron emission tomography (PET) scans to detect cancerous tumors without invasive operations. This is possible by giving the patient a glucose analogue of slightly radioactive FDG, The cancer cells suck this up and it accumulates in cancerous tumors and can easily be detected in a PET scan.
Another study published in the journal Cancer investigated various glucose transport mechanisms in human breast cancer.
Glucose transport across cell boundaries is performed with the help of various protein enzymes. They found that the so-called Glut-1, Glut-2 and Glut-4 protein enzymes were active in breast cancer, but Glut-3 and Glut-5 mechanisms were not as active. Glut-1 was the most actives means of taking glucose into breast cancer cells. Such studies can help identify ways to slow down or inhibit the sugar feeding of cancer cells.
Another study published in the British Journal of Cancer looked at breast cancer rates in various countries. The researchers found that the rate of breast cancer in older women (aged 65-69) were positively correlated with sugar and fat consumption.
Yet another study published in The American Journal of Clinical Nutrition examined risks for pancreatic cancer and consumption of sugar sweetened foods. The study looked at 77,797 women and men.
This study found that those who consumed the most sugar were 1.95 times as likely to get pancreatic cancer as those consuming the least amount of sugar. Similarly for soft drinks, those who consumed most were 2.3 times as likely to get pancreatic cancer as those who consumed the fewest soft drinks.
The researchers thought that high levels of blood glucose created oxidative stress which resulted in free radical damage to the pancreatic cells. The idea is that the regions of the pancreas produce hormones have low concentrations of antioxidant enzymes. Thus, they are especially susceptible to glucose created free radicals.
Yet another study published in the British Medical Journal examined how the consumption of sugar and fat affected the risk of colorectal cancer.
They found that the overall calorie intake of those with large bowel cancer was 18% higher than their control group without cancer. Those with cancer consumed 21% more carbohydrates than those without cancer.
The cancer patients consumed 41% more sugars with little or no fiber and 19% less natural sugars with fiber. They found that the third of the study group consuming the most refined sugars (with high energy to fiber ratios) had an 8 times greater risk of contracting large bowel cancer than those in the lower third of refined sugar consumption.
If you’re not convinced already, another study published in the journal Cancer Causes and Control looked at the medical history of 98,030 women aged 55 to 69 years in Iowa. These women were mailed a questionnaire on known and suspected cancer risk-factors.
They found that BMI was related directly to cancer risk. Cancer risk for 60% of the women with the highest BMIs was from 40 to 70 percent higher than for those in the lowest 40% of BMIs. There was also double the risk of colon cancer in women consuming the most sucrose-containing foods.
You Can Stop Cancer Before it Starts
Research tells us not only the causes of cancer, but how to prevent many cancers types.
Cancer prevention strategies include consuming healthy fruits and vegetables and avoiding processed sugars that are depleted of fiber.
Unfortunately, this requires some effort on your part. You’ll need to about most of the manufactured foods that contain lots of added sugars. And, you’ll need to eat more raw fruits and vegetables.
While many blame genetics, the gene pool has not changed dramatically enough to cause the epidemic of obesity. What has changed is the foods we eat. The genetic code allows for enormous fat increases when the body is provided with a typical modern Western diet.
The Proceedings of the Nutrition Society article Body-weight regulation: causes of obesity indicates: “However, the increasing rates of obesity cannot be explained exclusively by changes in the gene pool, although genetic variants that were previously ‘silent’ are now being triggered by the high availability of energy- and fat-dense foods, and by the increasingly sedentary lifestyle of modern societies.”
Our Western lifestyle consists increasingly of a low energy, sedentary life with many labor saving devices. Couple this with high-energy, low fiber meals containing lots of refined sugars. This lack of physical activity while consuming far too many calories can only lead to energy storage in the form of ugly fat.
In addition, when we eat we are not receiving the “I’m full” signals that would cause of to stop eating. Instead of consuming fiber rich foods that fill up the stomach, we are consuming highly refined carbohydrates with nearly all the fiber removed. We get the sugars without the fiber in the raw foods that would slow digestion.
Another article in the European Journal of Clinical Nutrition entitled A satiety index of common foods tells us, “These kinds of extremely low-fat, high-carb meals do not keep hunger at bay because they are not based on slowly-digested carbs and probably don’t contain enough protein.”
The modern food industry is dedicated to sales, marketing, and food research. They have scientifically investigated different levels of salt, sugar, fat, the chewing sound, and the feeling of food in your mouth. They optimize these factors in order to drives sales. Michael Moss’ book, Salt Sugar Fat tells the story of how the food industry has become so profitable by concentrating on taste, convenience and cost. All important to the modern consumer.
And, don’t forget that these convenience foods are, well, convenient. They are always at hand. As soon as you think you’re hungry you can reach for a convenience food. You may remember the Snickers candy bar slogan, “Don’t let hunger happen to you.” So, always have a few candy bars with you so you don’t experience hunger.
2001 Commercial – “Don’t Let Hunger Happen to You”
Eventually you may develop a food addiction. You’ll fall in love with a food that makes you feel good. You won’t be able to resist another severing until that food is gone. You’ll always find reasons to indulge in more of the food. And, you’ll eat too much even while knowing it’s not healthy.
The best way to pack on the fat is to avoid natural, raw foods. Instead, consume as many manufactured convenience foods as possible. Avoid raw foods that contain fiber which slows digestion, helps moderate insulin levels, and helps prevent constipation, hemorrhoids, and some cancers.
Much research has goon into manufactured foods to ensure that they are engineered to be highly palatable. They will taste good and you will enjoy eating them. They contain precise amounts of sugar, salt and fat to make you want to eat them. And, often, eat them to excess.
Second, ensure that the manufactured foods you consume do not contain much fiber.
You want to make sure that the sugars in the manufactured foods are digested and get into your blood stream as quickly as possible. This puts more glucose into your blood than you can possible use. Excess blood glucose causes insulin to spike in order to store this sugar energy in fat cells.
Your fat cells will bulge and even more ugly fat cells will be created to store all this excess energy.
Third, watch the TV commercials for new convenience foods. Make sure to give them a try. After all, they have been engineered to taste great and be less filling so you can have more.
Do Not Exercise After Meals
After all, you want the excess glucose to be stored as fat for later use. Using it after meals for exercise defeats the purpose of consuming the manufactured foods.
As your insulin levels begin to spike as more glucose enters you blood stream, the glucose is stored. The spike in insulin levels actually will remove a lot of glucose from your blood stream, lowering glucose levels and decreasing your overall energy level. You will begin to feel tired, and will definitely not want to exercise.
This is a time for a nap. Take an after meal siesta to celebrate the addition of fat to your already bulging fat cells.
Packing on Ugly Fat is Easy
Just do what the average American already does to experience weight gain. Have a “busy” life that requires manufactured convenience foods. Eat these meals every day and watch your ugly fat accumulate.
But, if you want to burn more fat and get slimmer, you need to do two things:
Release fat from the fat cells so it can be “burned” for energy more easily. The best product for this is [popup_product]forskolin[/popup_product]. You can look at our page on forskolin for more information.
Burn more fat by increasing your metabolism. Diets usually lower your metabolism. But, by taking [popup_product]7 Keto DHEA[/popup_product] you can actually increase your metabolism. Take a look at our post about 7 Keto DHEA for more information.
