Low Carb Diet Basics
Most people use low-carb diets as a way to lose weight, and research shows that a moderately low-carbohydrate diet can be heart-healthy when low in saturated fat. Carbohydrates, or carbs, are the sugars, starches, and fiber contained in grains, fruits, vegetables, and dairy products. With the exception of fiber, carbohydrates are the body's preferred energy source.
An extremely low carb eating plan causes the body to go into a metabolic state known as ketosis, which happens when the body burns stored fat for energy and may result in weight loss.
There are a number of diets based on the principle of reducing carbs, including the Atkins diet, Dukan diet, keto diet, paleo diet, Whole30 diet, and the South Beach diet. These diets differ in the particulars of how many carbs may be consumed, and what specific foods are in or out, but all of them are based on significantly lowering the amount of carbohydrates consumed.
A low-carbohydrate diet is commonly defined as consuming no more than 20 g of carbohydrate per day, while a moderate-carbohydrate diet is thought to provide between 40% and 55% of calories from carb, which amounts to at least 200 grams daily on a 2,000-calorie diet.(see #2 reference, below)
Foods that are limited or avoided include bread, pasta, whole and refined grains, potatoes and other starchy vegetables, sugar, sweets (including cookies, ice cream, candy, and soda), milk, and high-carb fruits like apples, grapes, and bananas.

What to Eat on a Low Carb Diet
On a low-carb diet, foods that are low in carbohydrates are the central focus. While it is not possible (or desirable) to eliminate carbs altogether, the goal of a low-carb diet is to consume no more than 20 grams of carbohydrate per day on a 2,000-calorie diet. One simple guideline for vegetables is that vegetables grown above ground (as opposed to root vegetables) tend to be lower in carbs. Typical foods to eat include:
Low Carb Foods Nonstarchy vegetables (such as zucchini, broccoli, cauliflower, cabbage, spinach, and lettuce)
Meat (including beef, poultry, pork, and lamb)
Fish and seafood
Eggs
Dairy (including cheese, butter, cream, and yogurt)
Lower-carb fruits (berries, cherries, plums, kiwi, and melon)
Nuts and seeds (including nut butters)
