IT sounds like it’s too good to be true, there’s a diet that allows you to eat junk food three times a day.
The “dirty keto” diet follows the same rules as the original keto diet – low carbs high fat – but pays more attention from where the macros in the food come from.

Macros are essentially the macro nutrients in food, so rather than following calories you can make sure you’re body is getting all it needs by eating the right macros.
The dirty keto diet still says you need 60-75 per cent of your daily calories from fat, 15-30 per cent from protein and 5-10 per cent from carbs.
As long as you meet these percentages that’s all that matters.
So that means instead of focusing on healthier high-fat foods you can go mad on junk foods like cheese and low-carb burgers.

But that’s not a good choice for your long-term health and could cause life-threatening conditions like heart disease.
“If you are replacing carbs with junk food you are going to be increasing the amount of free sugars, the type you should be cutting down on,” dietitian Helen Bond told The Sun Online.
“It’s also higher in salt and higher in cholesterol raising fat, so they’re all not good for your long term health.
“High sugar intake is linked to dental cavities, high energy can lead to weight gain if you’re not compensating elsewhere, high salt is blood pressure raising and high saturated fat is cholesterol raising.

“It’s teaching you to go from sugar high to sugar high rather than having wholesome, sustainable carbohydrates which is the food group you’ve removed.
“It’s a short term goal in terms of weight loss, but sustainability in the long-term is very short lived.
“These aren’t abiding by healthy eating principles you can stick to for life.”
Low carb high fat diets have been around since the 1920s but have soared in popularity in the last few years with the backing of celebs like Kim Kardashian.
They are said to force the body to burn fats as fuel, leading to rapid weight loss.

“It will result in weight loss because you are removing a food group from your diet, and anything that involves removing a food group obviously cuts calories,” Helen added.
“But from a health point of view carbohydrates should be 50 per cent of your diet, they are a source of fuel for your body and brain so you will feel very grumpy and moody if you cut them out.
“Plus they are a key point of fibre in your diet so you will be missing out on the healthy 30g a day.”
As well as helping you slim down, ketogenic diets are also thought to keep blood sugar levels stable.
But new research suggests this claim could be misconceived.

Tests on mice put on ketogenic diets showed evidence of insulin resistance in the liver – a condition that prevents the body responding properly to the hormone insulin and is a stepping stone to type 2 diabetes.
Lead researcher Professor Christian Wolfrum, from ETH Zurich University in Switzerland, said: “Diabetes is one of the biggest health issues we face.
“Although ketogenic diets are known to be healthy, our findings indicate that there may be an increased risk of insulin resistance with this type of diet that may lead to type 2 diabetes.

“The next step is to try to identify the mechanism for this effect and to address whether this is a physiological adaptation.
“Our hypothesis is that when fatty acids are metabolised, their products might have important signalling roles to play in the brain.”
The findings are reported in the Journal of Physiology.
The ketogenic diet was first developed in the 1920s as a treatment for epilepsy.
Doctors discovered that a low-carb diet appeared to help reduce seizures, possibly by altering the supply of energy to the brain.
