While Keto Diet is good for weight loss, there are a few well-known side effects related to it.

Some of them can be unpleasant. Some side effects of the keto diet are bound to occur, though others only happen when the diet is implemented poorly, typically by failing to eat balanced, nutrient-rich foods as a part of a high-fat, low-carb diet. Below are the side effects that you should know about.

• Keto flu: It is an immediate side effect of switching to a very-low-carbohydrate diet and is one explanation why people often find sticking with it in the early days pretty challenging.

• Nutritional deficiencies: Keto requires eliminating a variety of nutritious, carbohydrate-rich foods from the diet, like whole grains and certain fruits and vegetables. 

• Ketoacidosis: While healthy people typically produce enough insulin to prevent excessive ketones from forming, there is a small risk that ketone levels can climb too high, causing a dangerous condition called ketoacidosis, where acid levels in the blood reach toxic levels.

The keto diet may help you to reduce your carb intake and lose weight, but it does have side effects, including constipation. You can also reduce your risk of constipation by eating more whole, high-fiber foods to help keep your bowels moving.
