What is a keto diet? 

Keto diets have gained significant popularity over the last couple of years. This type of diet has been found to be effective in helping people lose weight and improve their health. The Keto diet works by minimising carbohydrate intake and increasing fat intake in order to make the body utilise fat as a form of energy, subsequently burning more fat.

To see the benefits of keto, you need to restrict yourself to eating between 20-50 grams of carbs a day. To put that in perspective, the average person eats between 225 and 325 grams of carbohydrates a day, so sticking to the keto requirements is quite a commitment! Instead of carbs, a keto diet involves eating foods rich in proteins and fats, such as meats, eggs, cheese, fish, nuts, butter, oils, seeds, and vegetables.
