Low carb diets are very effective weight loss plans, especially for men, over the short term. Himbeer Ketone Low carb (or high protein) diets work by restricting the amount of carbohydrates you are allowed to eat to under 10% (usually) and increasing the amount of protein and fat you consume (to 40% to 60%). When you restrict carbohydrates, your body goes into a metabolic state called ketosis, where the body burns fat instead of carbs for fuel. Short term, this works great. Long term, however, this type of diet is believed to cause medical problems such as kidney failure, high cholesterol, kidney stones, gout, heart disease and even osteoporosis. The Atkins Diet and the South Beach Diet are the two most well known low carb diets.
