What is the Ketogenic Diet?

The ketogenic diet is a low-carb, high-fat diet that limits carbohydrate consumption to 50g per day.1 The aim of the diet is to reduce carbohydrate intake to a level that puts the body in a state of ketosis. When in this state, the body burns fat for fuel instead of glucose. There is evidence suggesting that ketogenic diets can help with fat loss and appetite control.1

A ketogenic diet can be restrictive, and it may be difficult to include enough fibre in your diet (the NHS recommends 30g a day for adults) . This ketogenic diet food list will help you follow a keto diet while helping to reduce the risk of any nutritional deficiencies.

 

Ketogenic Diet Food List

Animal Proteins

1. Chicken thighs

Per 100g: 295kcal; protein 23g; carbs 0g; fat 23g

Chicken thighs contain more fat than chicken breasts. This makes them a good keto option as many of your calories will need to come from fat. For those with high daily calorie requirements, fattier cuts of meat will be a good source of energy. Chicken thighs are also rich in B vitamins and selenium.

 

2. Pork chop

Per 100g: 774kcal; protein 32g; carbs 0g; fat 6.4g

3. Sirloin steak

Per 100g: 213kcal; protein 25g; carbs 0g; fat 13g

A good red meat option for followers of a keto diet. Sirloin steak’s high in iron, zinc and B12, which are all important for energy production.3 A protein source that’s high in essential amino acids, an average-sized steak (6oz or 170g) will provide 40g of protein and 362 calories.

Take home message

A ketogenic diet is a very low-carb, high-fat diet. Because carbohydrates are restricted to less than 50g per day on the diet, it’s important to make sure energy and nutrients are consumed from other dietary sources.

If you’re interested in following a ketogenic diet, consider eating some of the foods listed in this article to make sure you consume a range of vitamins and minerals as well as adequate amounts of protein and fibre.
