Finding yourself confused by the seemingly endless promotion of weight-loss strategies and diet plans? In this series, we take a look at some popular diets—and review the research behind them. In the 19 th century, the ketogenic diet was commonly used to help control diabetes. In it was introduced as an effective treatment for epilepsy in children in whom medication was ineffective. However, this diet is gaining considerable attention as a potential weight-loss strategy due to the low-carb diet craze, which started in the s with the Atkins diet a very low-carbohydrate, high-protein diet, which was a commercial success and popularized low-carb diets to a new level. Today, other low-carb diets including the Paleo, South Beach, and Dukan diets are all high in protein but moderate in fat. The brain demands the most glucose in a steady supply, about grams daily, because it cannot store glucose. During fasting, or when very little carbohydrate is eaten, the body first pulls stored glucose from the liver and temporarily breaks down muscle to release glucose. If this continues for days and stored glucose is fully depleted, blood levels of a hormone called insulin decrease, and the body begins to use fat as its primary fuel. The liver produces ketone bodies from fat, which can be used in the absence of glucose.
One argument against the consumption of a high fat diet is that it causes obesity. Sumithran P. Now I know patients that are starting this program are on diabetic medicines and when dropping carbs need to adjust their meds but as they say this ain’t rocket science. HDL cholesterol levels significantly increased, whereas LDL cholesterol levels significantly decreased after treatment. However, it is possible to modify the diet to emphasize foods low in saturated fat such as olive oil, avocado, nuts, seeds, and fatty fish. As I explain in Unsavory Truth, the influence of industry funding is often unconscious, unintentional, and unrecognized. What is it? I have high cholesterol and I am type 2 diabetic using 30 units approximately of insulin. Blood levels during a normal diet, ketogenic diet and diabetic ketoacidosis [ 35 ]. A modified carbohydrate diet following the Healthy Eating Plate model may produce adequate health benefits and weight reduction in the general population. Abstract Obesity is reaching epidemic proportions and is a strong risk factor for a number of cardiovascular and metabolic disorders such as hypertension, type 2 diabetes, dyslipidemia, atherosclerosis, and also certain types of cancers.
Obesity is reaching epidemic proportions and is a strong risk factor for a number of cardiovascular and metabolic disorders such as hypertension, type 2 diabetes, dyslipidemia, atherosclerosis, and also certain types of cancers. Despite the constant recommendations of health care organizations regarding the importance of weight control, this goal often fails. Genetic predisposition in combination with inactive lifestyles and high caloric intake leads to excessive weight gain. Even though there may be agreement about the concept that lifestyle changes affecting dietary habits and physical activity are essential to promote weight loss and weight control, the ideal amount and type of exercise and also the ideal diet are still under debate. For many years, nutritional intervention studies have been focused on reducing dietary fat with little positive results over the long-term. One of the most studied strategies in the recent years for weight loss is the ketogenic diet. Many studies have shown that this kind of nutritional approach has a solid physiological and biochemical basis and is able to induce effective weight loss along with improvement in several cardiovascular risk parameters. This review discusses the physiological basis of ketogenic diets and the rationale for their use in obesity, discussing the strengths and the weaknesses of these diets together with cautions that should be used in obese patients. Obesity is a rapidly growing epidemic worldwide [ 1 ] that has nearly doubled since For family physicians, obesity is one of the most challenging problems confronted in daily practice and despite the efforts of both patients and physicians, this disorder is increasing in prevalence. Obesity is one of the principle risk factors for cardiovascular disease and along with dyslipidaemia, hypertension and diabetes contributes to the metabolic syndrome [ 3 ].
