Americans put on anywhere from 1 to 5 pounds during the holidays. There are safe and not-so-safe methods of losing those few extra pounds, according to LSU AgCenter nutritionist Dr. Heli Roy.
If you are tempted to try a low-carbohydrate diet, research shows that those diets are not safe. High-meat, low-carbohydrate diets lead to an increased risk of kidney stones, says the LSU AgCenter nutritionist.
In the August issue of the "American Journal of Kidney Diseases," Dr Chia-Ying Wang said that acid load in the blood increased as much as 90 percent while subjects were on diets that severely restricted carbohydrates. Another compound found in the kidney that inhibits kidney stone formation was reduced by almost 25 percent.
"People may lose a lot of weight quickly on the diet, but this is water loss,"
The LSU AgCenter nutritionist says, however, that the body loss is not fat loss and therefore is not permanent. As soon as you eat carbohydrates more liberally, you will hold water and gain weight.
When carbohydrates are restricted, the body goes into ketoacidosis. This condition results from burning too much fat when there aren’t adequate sources of carbohydrates available and when ketones, which are formed when fat is burned for energy, accumulate in the blood.
"Ketones increase blood acidity and can lead to coma if they go too far,"
What are some safe ways to diet?
