The Advantages of a High Protein Low Carb Diet

The advantages of a high-protein, low-carb diet stem from its restriction of refined carbohydrates, according to Brigham and Women's Hospital. White rice, white bread, tonics, white crackers, sweets, jams and jellies are examples of refined carbohydrates. Reducing consumption of such foods helps to control blood sugar and insulin levels. A high-protein, low-carb diet---also known as the Atkins diet---has other benefits, such as weight loss and lower triglyceride levels.

Research and Scientific Proof

• Brigham and Women's Hospital explains that high-protein, low-carbohydrate diets improve triglyceride and cholesterol levels. High-protein, low-carbohydrate diets were also found to help more with weight loss than a traditional low-fat diet over a six-month period.
  However, over a one-year period, a high-protein, low-carb diet is no more effective than a traditional low-fat diet. There's no proof that low-calorie diets are less effective than high-protein, low-carb diets, according to Brigham and Women's Hospital.

Concerns

• High-protein, low-carb diets may produce short-term results but should be avoided over the long term, according to Brigham and Women's Hospital.
  Brigham and Women's Hospital states that there are some major health concerns associated with low-carb diets that are high in protein. High-protein diets make kidney stress significantly more likely. Also, a lack of carbohydrates can cause ketosis and bad breath. High-protein, low-carb diets also contain less plant protein, fiber and fresh fruit than other types of diets. Low-carb diets that sacrifice vegetables and whole grain also sacrifice valuable nutrients such as fiber and vitamins, according to MyPyramid.gov. This can lead to constipation and hinder cancer prevention.
  High-protein, low-carbohydrate diets should be avoided during pregnancy, breast feeding or during the childhood and preteen years, according to the Virginia State University Cooperative Extension. During these periods of life, the body requires large quantities and varieties of nutrients on a daily basis to stay healthy.
