What is Keto Diet? | Keto Meal Plan | Keto Supplements | Holland & Barrett

This on-trend way to eat has soared in popularity in recent years with its rep of helping people to lose weight thanks to its high-fat and low-carb methods.

Keto diet for beginners

The ketogenic diet, or keto diet for short, is a high-fat and low-carb plan that aims to turn your body into a metabolic state called ketosis.

Ketosis is where your body burns fat, rather than carbohydrates for fuel. The body usually opts to burn glucose, a sugar found in carbohydrates, for fuel, but if there’s no carbohydrates, the body’s next option is fat.

Changing to a keto diet, means the fat that you consume, or that is stored, is burnt. This is why the keto diet has become a favourite with those looking to lose excess pounds.

It’s worth noting that the body takes a few days to switch from choosing to burn glucose, to fat, so results aren’t instant.

Keto diet foods

A keto diet is made up of around 70% fats, 25% protein and 5% carbs.

To kickstart ketosis, 20g, and no more than 50g, of carbs should be eaten per day. Minimise potatoes, pasta, bread and rice. Carbohydrates are also in alcohol, sweets and fizzy drinks in the form of glucose and sugars. Fruits, especially the sweeter ones, contain carbs; a small banana has around 20g of carbs.

A normal keto meal plan is packed with high fat foods like avocados, meat, fish, eggs, cheeses, oils, butter, nuts and seeds and can be suitable for vegetarians.

Veggies aren’t off the menu; cauliflower, cabbage, spinach, courgette, lettuce, cucumber, asparagus and kale are all keto dieters go-tos thanks to their low carb content. Cook your veggies in butter and drizzle salads with oil to increase the fat content. Peppers, green beans, broccoli and sprouts also are a fave, but do have a higher carb content.

Keto diet side effects

Keto flu is the most common side-effect people experience when adapting to the ketogenic diet. Symptoms like fatigue and fogginess are common in the first few days as your body gets used to eating little-to-no carbohydrates6. To tackle keto flu, make sure you drink plenty of water and get plenty of sleep.

Can you exercise on the keto diet?

Yes, you are able to exercise while following the keto diet. However, if you’ve just made the transition to keto, you may find that your body may struggle to complete certain activities.

When taking part in high intensity exercises like circuits and sprinting, your body looks for something to burn quickly, which is usually carbohydrates. And, seeing as the keto diet limits the amount of carbs, you may find high intensity workouts a little more difficult. Avoid HIIT and circuits while your body gets used to restricting carbs.

Low intensity cardio burns more fat to fuel your body. Try swimming, jogging and cycling.  If cardio isn’t your thing, strength training is also an option – try fewer reps with lighter weights to see how you fair.

Keto supplements

Before you do any exercise, it’s important to ensure you’re eating enough, both calories and fat. If you already supplement your diet with sports products, check the carbohydrate content on the labels. There are also specific keto diet friendly supplements that you could also try to fuel your next workout.
