Low carbohydrate diets can help a person lose weight and can help a person maintain good health.
Carbohydrates and Cholesterol
One of the most common debates among dieticians is the role that carbs play in eating a healthy diet. Some dieticians believe that carbs aren’t essential for adequate nutrition and that it increases your risk of neurological disorders, cancer, and diabetes.
Others believe that we need to eat carbohydrates in order to have good health and that carbs should be a part of everyone’s diet, making up the majority of the calories we take in.
The scientific research shows some significant evidence that low carb is actually better than low fat in reducing markers and risk factors for heart disease, including in regards to the lipid profile.
How many carbs do we need?
According to the Institute of Medicine, every adult should take in at least 175 grams of carbohydrates per day, especially women who are pregnant. This represents about 29 percent of the calories taken in by a diet containing about 2400 calories. In pregnancy, it is recommended that proteins be restricted to less than 15 percent of calories consumed and that about 30 percent of the calories taken in should come in the form of carbohydrates.
Adrenal fatigue is another medical condition that requires moderate carbohydrate consumption. Adrenal fatigue happens when the adrenal glands are overworked so that cortisol levels are too low. Cortisol levels increase whenever a person adopts a low carb diet.
Carbs are recommended for athletes who train up to six days per week because carbs are the optimal source for cellular fuel in intense workouts and weight lifting for adequate performance.
Athletes who restrict carbs generally develop poor training habits and need to go on a diet that contains at least some carbohydrates for cellular fuel during exercise. Athletes should take in about 20 percent of their calories as carbohydrates. It depends, however, on the health goals of the individual, the individual’s weight, and on their training schedule. Those that exercise heavily need 40 to 50 percent of their calories from carbohydrates. They also need fat, which will be quickly metabolized by the body during a workout.
In short, low carbohydrate diets are not for everyone.
Though, even bodybuilders and other athletes can and do follow modified low carb diets, namely, the Cyclical Ketogenic diet and Targeted Ketogenic Diet, where carb intake fluctuates round workouts.
For the obese and those with overweight issues, a low carb diet can really serve 2 major purposes, to lose the weight AND keep it off.
Additionally, those with type 2 diabetes or prediabetes will also benefit from a low carb plan in stabilizing blood sugar levels, and significant weight loss, which can result in the reversal of type 2 diabetes.
How Low Carb Diets Work
Low carb diets restrict carb intake to as little as 20 grams per day, such as the case in the Ketogenic diet. This restriction prompts a metabolic process known as ketosis, where the body begins to burn body fat and dietary fat for fuel instead of dietary carbs, which turn into glucose fuel in the body.
Contrary to all the hype about fat, low carb diets are fat rich, and are primarily focused on a high intake of healthy fats, which in turn promote the body’s natural fat burning process.
But what about cholesterol?
What The Studies Show
The Mayo Clinic states that a ketogenic diet has desirable effects on diabetes, heart disease, and metabolic syndrome and that eating a low carb diet is more effective in lowering bad HDL cholesterol than diets that are moderate in carbs.
While some studies have shown the intake of saturated fat to raise blood cholesterol levels, these studies are almost always short in duration, as little as a few weeks. In fact, several long-term studies have shown no association between saturated fat and high blood cholesterol levels.
Additionally, studies of low-carbohydrate high saturated fat diets suggest no impact on blood cholesterol and in fact lower markers for heart disease.
• Significant weight loss and reduced body mass index
• Significant improvements in several heart disease risk factors: lower level of triglycerides, healthier blood–pressure
• Improved fasting glucose
• Reduced risk for metabolic syndrome, which is a risk factor for heart disease
• Decreased levels of belly fat and waist size
• Improvements in the good HDL cholesterol levels
You should talk with your doctor before altering your diet, especially if you suffer from heart disease or high cholesterol. A nutritionist or a dietician can help as well.
