Benefits of a Low-Carb Diet
A low-carbohydrate diet limits dietary carbs, such as grains, starchy vegetables, and fruits. This dietary plan emphasizes dietary protein and fat and it is used for weight loss and to lower the risk of heart disease, diabetes, and certain cancers.
As the name implies, a low-carb diet restricts your consumption of carbohydrates, a type of macronutrient. Common foods that contain carbs include grains, seeds, legumes, vegetables, fruits, and milk. Your body needs some carbs for fuel. Sugars and starches are broken to simple sugars during the digestion process. They go into the bloodstream to form glucose and enter the cells of the body. Extra glucose is stored in the muscles and liver for later, or it is converted to adipose tissue (fat).
Low-Carb Diet Theory
The theory behind the low-carb diet is that insulin prevents the breakdown of fat by allowing sugar to be used for energy. By decreasing carbs, you have lower insulin levels, which allow the body to burn stored fat and shed excess pounds.
The low-carb diet plan allows for certain vegetables, fruits, and whole grains. The daily limit for carbohydrates is 50 to 150 grams. The 2010 Dietary Guidelines for Americans recommends that your carbohydrate intake make up around 50 percent of your total daily calorie needs.
Benefits of a Low-Carb Diet
There are two main benefits of the low-carb diet: weight loss and prevention or control of certain diseases.
- Weight Loss – Many people can lose weight on the low-carb diet. Studies show, that you must continue to follow this dietary plan in order to maintain your weight. Those who continued for two years lost an average of 9 pounds. Researchers believe that this diet works because the extra protein keeps you feeling full for a longer period of time so you don't eat as often.
- Prevents or Controls Diseases – Any diet that helps you lose weight will reduce or even reverse the risk factors for diabetes and heart disease. Also, the low-carb diet improves HDL cholesterol, the good kind of cholesterol that helps the body eliminate fat buildup.
The Disadvantages of the Low-Carb Diet
As with most other diets, the low carb diet has some disadvantages. These include:
- Side Effects – When you suddenly restrict or drastically eliminate carbs, you could experience a variety of temporary health side effects. These include dizziness, headaches, fatigue, and constipation.
- Nutritional Deficiencies – With this dietary plan, you could suffer certain nutritional deficiencies, as well as insufficient fiber. To avoid this, take vitamins or supplements while you are cutting out carbs.
- Ketosis – When you do not have enough glucose for energy, the body breaks down stored fat. This causes ketones to build up in the body, a condition known as ketosis. Restricting carbohydrates can cause ketosis, and symptoms include nausea, bad breath, and mental fatigue.
Studies Find that Low-Carb Diet Helps Overall Health
A recent review of 17 different studies that followed obese people on low-carb diet plans found that dieters lost around 18 pounds during a six month to one year period. Overall, these participants showed improvement in blood pressure, fasting blood sugar, waist measurement, triglycerides, and HDL cholesterol. One small study found that dieters who were trying to maintain weight loss burned more calories each day by eating a low-carb diet.
