What Are Low-Carbohydrate Diets?
Low-carbohydrate diets are those that reduce the amount of carbohydrate-containing foods you eat each day, from about 60% of total calories in the typical American diet to as little as 5%. Foods that contain mostly protein and fat are substituted.
Low-carbohydrate diets have not been scientifically proven to be effective for long-term weight management, and their long-term safety is questionable and unproven.
Disadvantages of Low-Carbohydrate Diets
The following is the list of disadvantages of low-carbohydrate diets:
- Important nutrients are missing from these diets and cannot be replaced by supplements.
- These diets are hard to follow because they lack variety, resulting in cravings for high- carbohydrate, high-fat foods. Eating less than 100 grams of carbohydrates a day is very hard in the long run, since Americans are accustomed to eating 275 grams a day.
- Although the diet produces rapid weight loss initially, the weight loss doesn't come from weight loss alone. Instead, it comes from loss of water and electrolytes.
- Maintaining weight loss is difficult, and if a dieter "cheats", a surge of insulin can cause sodium and water retention and subsequent weight gain.
- Poor athletic performance may result in the depletion of stored glycogen. Carbohydrates are the main source of this chemical in human body.
- Potential risks include:
- The risk of chronic disease from too much fat and protein.
- The risk of heart disease, cancer, and stroke from diet low in fruits, vegetables, and
whole-grains.
- Dizziness, headaches, confusion, nausea, fatigue, sleep problems, etc. that result from mild dehydration.
- Rise in blood pressure with age.
- Rapid falls in blood pressure when standing up.
The Smart Way to Lose Weight
Follow official dietary guidelines, such as those of the
American Heart Association. A safe rate of weight loss is no more than 1 to 2 pounds per week.
- Make small, consistent changes in food selection and control portion sizes.
- Eat a variety of grains, fruits, and vegetables daily.
- Select food low in saturated fat and cholesterol and moderate in other fats.
- Reduce sweets, desserts, and beverages that contain sugar.
- Drink alcoholic beverages in moderation, if at all.
- Stay physically active.
- Record your body weight frequently.
Keeping the Weight Off
Anyone can lose weight on a diet. The harder part is maintaining the weight off. The diets do not deal with the underlying causes of being overweight, nor do they teach better lifelong eating and exercise habits. No food or diet provides a magic answer. Good habits are the key.
Ultimately, there is no escaping the fact that weight loss boils down to eating less (of the wrong foods) and moving more.
