Pubmed Ketogenic Diet
Diets have been at the center of animated debates for decades and many claims have been made in one direction or the other by supporters of opposite camps, often with limited evidence. At times emphasis has been put on a single new aspect that the previous diets had overlooked and the new one was to embrace in order to improve weight loss and well-being. Unfortunately, very few randomized clinical trials involving diets have addressed the combined question of weight loss and cardiovascular outcomes. The recently introduced ketogenic diet requires a rigorous limitation of carbohydrates while allowing a liberal ingestion of fats (including saturated fats) and has generated a flurry of interest with many taking the pro position and as many taking the cons position. The ketogenic diet causes a rapid and sensible weight loss along with favourable biomarker changes, such as a reduction in serum hemoglobin A1c in patients with diabetes mellitus type 2. However, it also causes a substantial rise in low density lipoprotein cholesterol levels and many physicians are therefore hesitant to endorse it. In view of the popular uptake of the keto diet even among subjects not in need of weight loss, there is some preoccupation with the potential long-term consequences of a wide embrace of this diet by large segments of the population. On the contrary, numerous lines of evidence show that plant-based diets are associated with reduction in oncological and cardiovascular diseases and a prolonged life span. The debate reproduced in this article took place during a continuous medical education program between two cardiologists with largely differing views on the matter of effectiveness, sustainability, and safety of the ketogenic diet compared to alternative options.
Despite continuous advances in the medical world, obesity continues to remain a major worldwide health hazard with adult mortality as high as 2.8 million per year. The majority of chronic diseases like diabetes, hypertension, and heart disease are largely related to obesity which is usually a product of unhealthy lifestyle and poor dietary habits. Appropriately tailored diet regimens for weight reduction can help manage the obesity epidemic to some extent. One diet regimen that has proven to be very effective for rapid weight loss is a very-low-carbohydrate and high-fat ketogenic diet.
Some people begin the ketogenic diet with the best of intentions but find it difficult to maintain over time. Bear in mind that keeping up with a 100 percent ketogenic diet all the time may not be practical or desirable over the long term. There may be times that you have a period of higher carbohydrate intake, such as before you go to the gym. You also may experience an uncomfortably low level of energy if you are in ketosis for a long period of time. However, you can still take advantage of the ketogenic diet, by using it in a targeted cycle. This would mean eating keto for several days then having a two-day break where you eat a higher level of carbs.
There are many diets to choose from and the ketogenic diet is just one of them. In the short term, proper diet and exercise helps you control your weight but there are many long term benefits. Lower rates of high blood pressure, high cholesterol, metabolic diseases like diabetes are all reasons to start dieting and exercising today. These lifestyle modifications do not need to be drastic and can start as simple promises to yourself. You can start by swearing off potato chips or go for a short walk around the neighborhood once a day. People do slip from time to time but it is not a reason to give up completely on dieting and exercising. Reward yourself occasionally with a nice delicious smoothie or day off at the gym if you’ve been going regularly. We wish you the best of health.
