Good For: Being the most extreme diet ever to reach the UK.
Overview:
Imagine a diet with NO FOOD for 10 days – that’s the KEN diet. KEN, standing for Ketogenic Enteral Nutrition, prohibits food completely and instead ‘feeds’ the dieter a special liquid formula via a tube up the nose. The tube delivers a constant drip of 130 calories, made up of protein and nutrients; dieters are also given extra supplements, antacids and laxatives.
They must wear the tube 23 hours a day (one hour a day is allowed off for bathing).
The diet is so severe that it encourages the body to enter into starvation mode, where it uses its existing fat stores for energy.
While there is nothing to physically prevent you from eating or drinking what you want while on the diet, the promoters say you won’t want to eat anything after a couple of days. Eating or drinking non-sanctioned food can obviously impact on the success of the diet, of course.
Pros:
- Claimed to help you lose up to 10% (average 4-9%) of your bodyweight every 10 days with KEN.
- Of that 10%, 66% is apparently fat, just under a third is water and you shouldn’t lose any muscle at all, say the creators.
- Allows subsequent cycles of KEN as long as you have 10 days off between cycles, during which time you will need to follow a special diet designed by the clinic.
- Supposedly suitable for most people; the liquid formula isn’t a high protein diet which can cause kidney problems. That said, however, anyone with existing kidney problems is not recommended to use it.
- The creators claim you won’t go hungry on the KEN diet.
- As well as losing weight, it is also claimed to help reduce blood pressure, blood sugar and cholesterol.
Cons:
- A healthy weight loss is considered to be 1-2lbs a week; this rapid weight loss can potentially be dangerous.
- Delivers an incredibly low 130 calories a day.
- Doesn’t help anyone who eats for emotional reasons.
- Doesn’t help the dieter to learn about proper portion control or healthy foods.
- Dieter has to walk around with a tube attached to their nose, and carry both the liquid and electric pump at all times. Even if it doesn’t feel uncomfortable, it’s certainly going to look odd.
- Installation of the tube in the first place can be unpleasant.
- Side-effects can include constipation as a result of a lack of fibre (though you will be given laxatives), as well as bad breath and exhaustion. Headaches can also be a problem if you don’t drink enough water.
- The KEN diet is expensive; at £350 per cycle, it’s not a cheap option.
- Experts warn it may encourage anorexia in those prone to it or with prior problems.
- You have to mix your own food; you will be given KEN powdered food to mix with a litre of water twice a day.
- As the diet is new in the UK, it remains to be seen if dieters can keep this weight off afterwards.
- If the tube becomes dislodged, there may be a risk of food going straight into the lungs.
Exercise:
Not recommended while on such a drastically reduced calorie diet.

Health Warnings:
Not suitable for anyone with kidney failure or an allergy to milk proteins.
Conclusion:
We’re willing to accept that the KEN diet does help people to lose weight; how can it not when you’re not actually eating anything? We still remain to be convinced of its safety however. Quite how refusing to eat anything at all can be considered a good thing, even for those clinically obese people whose health is in the balance, we can’t fathom.
One expert put it very well when he evaluated the KEN diet; he said the extreme nature of the diet was turning food into the enemy. We agree with him. The best diets are those that help dieters to address their issues with food and learn healthy eating habits, as opposed to making food your nemesis.
We think the KEN diet is just another example of an expensive fad diet that promises quick results with little consideration of the longer term.
