Weight loss diet plans are not hard to find but knowing which one is best can be a challenge. The low-carb and high-fat ketogenic, or keto, plan has proved popular in recent years.
He told Express.co.uk: “The keto diet is the high-fat, high protein and low carbohydrate diet.
“Your body goes into a state of ketosis, where it is burning fat as the primary energy source, rather than carbohydrates.
“Eating fat only helps to burn fat if you are in a state of ketosis.
“When you are on a low carbohydrate, high protein and fat diet the body utilises fat as its primary energy source; this process is called ketosis.”
What can you eat?
Those on the diet plan can tuck into foods that are low in carbs, high in healthy fats and with a moderate protein content.
This includes eating high fat foods such as fish, meat, dairy, eggs, avocados and nuts.
Slimmers should avoid foods high in carbs including pasta, rice, bread, some fruits and sugary treats.
While many people will follow the diet plan, slimmers should be careful not to make some common mistakes.
“A classic mistake is people use ‘high fat’ as an excuse to eat unhealthily,” Harry explained.
“Eating bacon with every meal, chugging whole milk and covering everything with oil or butter just because ‘you can’ or just because ‘it’s high fat’ is not good diet practice to get into.
“Another mistake is cutting out all veg – there are low carb veggies that are packed full of essential nutrients that you need to be eating.
“Keto diet isn’t an excuse to cut out all vegetables.”
Although the diet plan is a popular option, it might not be suitable for everyone.
The expert added: “The keto diet is not for everyone, it can be very ‘heavy’ on the digestion system and does not work with some people.
“While it can be very effective at losing fat, it does not suit some people. If you’re a vegetarian or vegan for example, it can be extremely difficult and monotonous to do as you’re limited to only a few food options.”
