If you’ve recently thought about trying a new diet to shed some pounds, the keto diet is probably the first thing that’s come to mind. The idea of maintaining ketosis has taken over the weight loss space ever since celebrities like Kourtney Kardashian and Halle Berry touted the keto diet in years past, pushing an extremely high-fat and nearly zero-carb! Being curious about the keto diet is only natural, because c’mon: There are very few other diets where copious amounts of bacon and cheese are on the menu. Simply listing the different ingredients you can and can’t eat while working your way through the keto diet won’t explain how exactly it works. The diet’s main principle is maintaining ketosis, a metabolic state that pushes your body to burn fat for daily fuel rather than glucose sourced from carbohydrates. Originally designed to help patients fight epilepsy, the keto diet supposedly guides you into ketosis by eliminating some significant food groups that you normally interact with every day—mainly, items containing sugars and carbohydrates, as these don’t allow your metabolism to use fat as a main energy source. Sugar and carbohydrates do not sound like they’re part of a healthy meal to most — but in reality, they can be found in some pretty nutritious items you’ll have to cut out of your diet entirely. It’s why nutritionists and health experts may be critical of the keto diet, especially since deprivation requires tons of willpower that might be counterintuitive to your needs. While the keto diet could result in serious weight loss for those who can stick to the diet’s plan, if you know you simply can’t give up bread or fruits, it’s okay — Stefani Sassos, MS, RD, CDN, a registered dietitian within the Good Housekeeping Institute, says that the Mediterranean diet or ‘flexitarian’ meal plans could also help you lose weight in the long run.

The newest buzzword to hit the diet world seems to be keto — which refers to the high-fat, low-carb ketogenic diet. But what exactly is the ketogenic diet, and is the weight loss program right for you? When you consume foods that contain carbohydrates, the body converts those carbohydrates into glucose, or blood sugar, which it then uses for energy. When this occurs, fat is broken down in the liver, thereby producing ketones, which are by-products of your metabolism. These ketones are then used to fuel the body in the absence of glucose. Data suggest the average American man over age 20 consumes A modified version of the ketogenic diet, which allows you to eat protein more liberally — at 20 to 30 percent of your total calories — with the same carbohydrate restriction, is the more commonly used version of the diet today. The ketogenic diet for weight loss is based on the idea that driving the body into ketosis will maximize fat loss. When these stores are depleted, the body resorts to burning stored fat for energy instead of carbs.
In the world of weight-loss diets, low-carbohydrate, high-protein eating plans often grab attention. The Paleo, South Beach, and Atkins diets all fit into that category. They are sometimes referred to as ketogenic or “keto” diets. But a true ketogenic diet is different. And it’s not the type of diet to try as an experiment. While it also has been tried for weight loss, only short-term results have been studied, and the results have been mixed. We don’t know if it works in the long term, nor whether it’s safe,” warns registered dietitian Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women’s Hospital. The keto diet aims to force your body into using a different type of fuel. Instead of relying on sugar glucose that comes from carbohydrates such as grains, legumes, vegetables, and fruits, the keto diet relies on ketone bodies, a type of fuel that the liver produces from stored fat.
