For the longest time I always considered myself a “low carb” kind of girl, but now I know my diet is quite the opposite. Actually, I don’t think I am on a “diet” at all…I just eat food! The goal of this article is not to bash “low carb” diets at all, but rather to empower you to be a proactive participate in your health and not fall victim to another diet scheme.
What Defines a Low Carb Diet?
A low carb diet limits or restricts carbohydrate consumption and is often used for weight loss. In general, low carb diets focus on proteins, including meat, poultry, fish, and eggs, and some non-starchy vegetables. Foods high in easily digestible carbohydrates (i.e. sugar, bread, pasta) are eliminated and low carb diets limit most grains, beans, fruits, starchy vegetables, and sometimes nuts and seeds. Not all low carb diets are the same and some diet plans allow certain fruits, vegetables and whole grains. The typical low carb diet includes less than 20% of your total daily calorie intake from carbohydrates (400 calories daily from carbohydrates*). Whereas the 2010 Dietary Guidelines for Americans recommends that carbohydrates make up 45-65% of your total daily calorie intake from carbohydrates (900-1,300 calories daily from carbohydrates*).
*Based on a 2,000 daily caloric intake
Carbohydrate Refresher
As previously discussed, carbohydrates are a type of macronutrient found in many foods and beverages, and naturally occur in plant-based foods (i.e. fruits, vegetables, nuts, grains, seeds, and legumes). However, some food manufacturers do add carbohydrates to processed foods in the form of starch or added sugar, which can be harmful to our overall health and waistline. Our bodies use carbohydrates as our primary energy source. Simple or complex carbohydrates are broken down into glucose, absorbed into the bloodstream (blood glucose), and then with the help of insulin the glucose enter our cells. Glucose can either be used by our body for energy, stored in our liver, muscle, or other cells for later use, or is converted to fat.
The Low-Carb Theory:
The theory behind the low-carb diet is that by decreasing carbohydrate intake our insulin levels are reduced, which causes the body to burn stored fat for energy and ultimately helps you shed excess weight and reduce risk factors for a variety of health conditions. Some low carb diets are ketogenic, meaning that they restrict carbohydrate intake sufficiently to cause ketosis (i.e. the Induction Phase of the Atkins Diet). Simply, ketosis means that our bodies are using fat for energy.
Weight Loss: Everybody is Doing it!
Two-thirds of Americans and an estimated 2.3 billion people worldwide are either overweight (BMI 25-29.9 kg/m2) or obese (≥ 30 kg/m2), and this epidemic is not getting any better. Unfortunately, many weight-loss programs don’t work or only offer temporary benefits. Our market is bombarded with so many diet plans, diet pills, high-protein programs, shakes, and other diet trends that claim your success in weight loss, or at least provide you with temporary benefits. Sadly, the term “diet” has turned into a fad and the pleasure and enjoyment of eating because something makes you feel good has long been overlooked. These mass produced weight loss “diets” aren’t sustainable long-term, and some are very dangerous. Truthfully, what good is a diet plan that helps you lose weight but now your health is at risk?
A High Carbohydrate Diet for Your Health:
The ancient Greek physician Hippocrates said, “Let thy food be thy medicine and thy medicine be thy food.” Since ancient times, plant-based foods, herbs, and spices have been used in the prevention of ailments and chronic diseases, including cancer. Epidemiological studies have demonstrated the correlation of fruit and vegetable consumption and the reduced risk of various diseases. So my question to you is why would we want to limit these extraordinary fruits, vegetables, nuts, whole-grains, seeds, and legumes simply because their carbohydrate content is higher than lean proteins? Studies have shown that high-protein diets, or diets rich in animal products and low in fruits and unrefined carbohydrates, are positively associated with colon cancer risk. Are animal products the enemy? Not necessarily, but they must be consumed in moderation and accompanied by an abundant amount of unprocessed plant-based foods. Dr. Fuhrman has a health equation that I live my life by:
H = N/C (Health = Nutrients/Calories)
“Your health is predicted by your nutrient intake divided by your intake of calories.” Dr. Fuhrman
Don’t limit your health by the amount of carbohydrates in your food, rather enhance your health by eating plentiful amounts of nutrient dense foods. Please note that I am not recommending you to stuff your bellies full of worthless carbohydrate crap, like cakes, sweets, pastries, and over processed refined grains. My goodness friends, eat food–real, raw, nutrient loaded, juicy, health-benefiting, wonderful, amazing, and delicious food! Your life and waistline will thank you!
