It seems like everyone is doing keto these days.
Kourtney Kardashian is back on it, Halle Berry is a fan and Alicia Vikander used it to get in shape for her role in Tomb Raider.
So it seems like a no-brainer to get onboard with the high-fat, low-carb plan which can help you drop kilos quickly.
But expert nutritionist Hebe Mills warns dieters that there’s such a thing as too much fat on the high-fat diet.
She told Express.co.uk that keto converts have to “be mindful of the high energy content in a number of foods recommended in the diet.
“Fat contains more calories than carbohydrate (which isn’t a bad thing in the slightest!) so it may be worth monitoring your energy intake if the purpose of the diet is for weight loss.”
The key to weight loss, no matter what plan you follow, is creating a calorie deficit and it’s too easy to go overboard when embarking on a keto’s high-fat eating plan.
Ms Mills also stresses the importance of keeping a varied diet while following the plan.
“Try to include as many different foods from the ‘allowed’ list as possible, this includes nuts, avocados, eggs, fish, meat aubergines, cheese and natural fats such as butter and olive oil. This will ensure you get a variety of nutrients,” she says.
“Seek advice from a nutrition expert and your GP before starting the diet – the ketogenic diet eliminates carbohydrates, forcing the body to rely on fat as a source of fuel.
“Considering carbohydrates provide the main fuel source to the brain, this is not a long term weight loss solution.
“I’m not a fan of elimination diets and think that excluding food groups is an unsustainable way to lose weight long term, but if you’re going to try it – do it properly under the guidance of an expert.”
Best keto foods
“It’s important to try and include a variety of foods while embarking on the diet to ensure you’re getting a range of nutrients,” Ms Mills says.
The easiest way to do this on keto is by eating foods that boast a varied nutrient profile, including; seafood such as including salmon, shellfish and tuna; non-starchy vegetables such as spinach, broccoli, kale and cauliflower; avocados, nuts and seeds; and berries.
