What Is a Low-Carb Diet?

A low-carb diet is an eating plan that promotes proteins and fats while limiting carbohydrates. Some versions of the diet allow certain carbohydrates, but others suggest eliminating most forms of carbohydrates for quicker weight loss.

Many people successfully lose weight by following a low-carb diet.The carbohydrates limited or excluded from this eating plan include sweets, most processed foods, legumes, grains, fruits and most vegetables.

Proponents of the low-carb diet claim these foods cause insulin spikes, which the body burns as fuel rather than burning fat. Foods encouraged on a low-carb diet include red meats, eggs, fish, poultry, nuts and non-starchy vegetables. Eating these foods helps to build lean muscle and burn fat.
