One of the most recent trends in dieting is the low-carbohydrate or "low-carb" diet. Examples of these diets are the Atkins' diet and the South Beach diet. Low-carb diets dramatically restrict the number of calories from foods such as bread, pasta, potatoes, rice, cereals, and sweets.
In the short term, these diets may provide positive results. However, studies have shown that after 6 months, low-carb diets are no more effective than other diets for weight loss. Although studies have also shown that, in most cases, these diets are relatively safe for up to 1 year, long-term studies are not yet available.
Because many low-carb diets restrict fruits and vegetables, most health care professionals recommended that people on these diets take a daily multi-vitamin and fiber supplement.
Before beginning any weight loss program, it is important to talk to a qualified health care provider. Possible side effects of a low-carb diet include constipation, diarrhea, dizziness, bad breath, headaches, sleeping problems, and nausea. Women who are pregnant and people who have diabetes, heart disease, high cholesterol, kidney stones, or a history of stroke should be cautious about trying a low-carb diet.
