The Link between Carbohydrates and Obesity
There is a popular belief that overweight people eat more carbohydrates than those without weight issues. But on the contrary, it’s the kind of carbohydrates you consume, not how much, that matters when it comes to weight management.
The results of a study on obesity showed that people with a higher body mass index – which takes into account both a person’s height and weight – tend to eat carbohydrates with a higher glycemic index.
Glycemic index ranks carbohydrates based on how they affect our blood sugar levels. Low GI foods only cause small fluctuations in our blood sugar and insulin levels while high GI foods do the opposite.
The height and weight of around 600 healthy participants were measured and they were asked to record the kind of carbohydrates they ate for a year.
The researchers noted two key findings: 1. as mentioned earlier, those with a higher body mass index ate more carbohydrates with a higher glycemic index; and, 2. the amount of carbohydrates they ate did not influence body mass index.
The results of the study suggests that a low-carb diet like the Atkins diet, which asks dieters to cut back on all carbohydrates, is missing the mark, when it’s actually the kind of carbohydrates you eat that determines your risk of obesity.
That’s because not all carbohydrates are created equal and because one-third of Americans need a high-carb diet.
Dr. Joseph Mercola explains that your body prefers the carbohydrates found in vegetables rather than grains because they are converted into simple sugars slower and decreases your insulin level.
However, if you’re addicted to refined carbohydrates like white bread, pasta and sugar-rich processed foods, don’t be surprised if you don’t like what you see when you step on the weighing scale.
How Refined Carbohydrates Increase Your Obesity Risk
Everyone needs to eat a certain amount of carbohydrates but your body’s ability to store carbohydrates is limited, so if you consume more carbohydrates than what you need, they are converted, through insulin, into fat and stored as fat, thereby increasing your risk of obesity, bloating, depression, fatigue, frequent sleepiness, and almost all chronic degenerative diseases.
Eating a meal or snack high in grain and sugar carbohydrates will typically generate a spike in blood glucose. Your pancreas compensates for this surge by secreting insulin into your bloodstream, which lowers your blood sugar. Increased insulin levels will suppress two other important hormones – glucagon and growth hormone – which are responsible for burning fat and sugar and promoting muscle growth.
While many dietitians consider the glycemic index to be an important tool, Dr. Mercola explains that is not very reliable because it contains many exceptions that render it ineffective.
For example, if you would follow the index standards, you will find that fructose is acceptable because it has a very low glycemic index, when in reality, fructose (especially in the form of high fructose corn syrup) is one of the main reasons why people are overweight. If your goal is weight loss, you should also avoid other low-glycemic-index foods like apple juice, chocolate and cherries.
The glycemic index is not a reliable method to lose weight or improve your health. One of the best ways to prevent your insulin levels from going overboard and your body from storing too much fat is by eliminating grains and sugars, which you can achieve through the no-grain diet.

How the No-Grain Diet Helps in Clearing Up Acne
Acne, pimples or zits, whatever you may want to call it, this common skin condition affects more than 80 percent of Americans, teenagers and adults alike, at some point in their lifetime.
An acne breakout can be a very stressful episode, at whatever age it may strike. Acne comes and goes on its own but some people develop severe cases of acne that warrant medical attention.
Every year, people suffering from acne spend hundreds of millions of dollars on different over-the-counter and prescription acne treatment methods, including antibiotics, drugs like Accutane, and even acne gadgets.
But what is the best way to treat acne?
Many dermatologists will tell you that what you eat has nothing to do with acne but they couldn’t be further from the truth.
Dr. Joseph Mercola explains that some people are predisposed to developing acne lesions. And if your diet is causing an increase in your insulin levels and associated insulin growth factors, it will trigger an acne breakout.
When you consume refined carbohydrates and sugar, it causes a spike in your insulin levels and a surge in an insulin-like growth factor called IGF-1 in your body. This in turn, leads to an overproduction of male hormones, causing your pores to secrete a greasy substance called sebum, which attracts the acne-causing propioniform bacteria.
Some say that acne started in the West because studies show that it is almost non-existent in non-westernized countries where refined carbohydrates and sugar are not widely consumed. No acne cases were found among Papua New Guinea islanders and Paraguayan hunter-gatherers, suggesting the significant role of environmental factors, such as diet, in acne.
So why isn’t your doctor telling you to change your eating habits to treat your acne? Simple: a healthy diet can’t be “sold,” and they can’t prescribe you with conventional acne treatments like topical acne creams and antibiotics.
The no-grain diet will help you radically reduce your insulin production by reducing or severely limiting your consumption of grains and sugars. This will involve avoiding bread, cereal, pasta, rice, potatoes, and corn.
For 40 years, Dr. Mercola had his own struggles with acne but after understanding the influence and dangers of grains on health, acne became a non-issue for him.
But helping prevent acne is just a side effect of the no-grain diet; leading you to optimal health is its main goal.
