What do I think of Miracle Noodles (Konjac Flour – Fibre in general actually)

Konjac Flour – Miracle noodle (low carb noodles)

Many people are just wanting to constantly try and make keto look like their old diet. The market knows this so these companies are constantly trying to find was to cheat the body into thinking it is eating food when it is actually eating frankenfood garbage.

There are mixed results on this stuff. From a WHO food additives safety report they show “no harm” but they did show weight increases in groups fed the Konjac flour vs. that of the control group which would seem to indicate a significant insulin response as the only factor between the two groups was the Konjac Flour addition to the feed. Calories and macros where the same for both groups. It also showed some increased insulin sensitivity but do we want insulin sensitivty or do we want low insulin?

There was also some evidence of enlarged colons in Konjac fed mice vs control groups. Colon enlargement is not a good thing and is a sign of underlying disease caused by inflammation. It was also shown that test animals given Konjac flour showed significant reductions in their ability to absorb vitamins and minerals therefore reducing their overall blood concentrations of various vital nutrients. This is typical of most fibre though. These results were duplicated in human subjects as well. Water soluble vitamins did not appear to be affected nearly as much as fat soluble ones mainly due to the effect of the fibre interfering with bile acid absorption which is vital for the absorption of most fat soluble vitamins as well as most minerals.

There was some evidence that diabetic test subjects (human) given Konjac flour with glucose showed significant decreases in in blood glucose and blood insulin levels at 30,60,90 and 120 minutes post prandial but showed significant increase at 180 minutes as compared to control. So that is not a benefit. Is it better to have lower levels short term or long term? I say long term is better. There were results that showed overall lowered fasting blood glucose after 30 days which could be promising but a total of 45 side effects were reported such as loose stool, flatulence, diarrhoea, and abdominal pain, sounds, or distension of the belly.

Some of the studies showed some reduction in bodyweight but it wasn’t determined if this was adipose or lean tissue. Weight loss is not always a positive benefit. It is not positive in sick people and the loss in weight could very well be due to the konjac causing malabsorption of vital nutrients.

There was some evidence as well of improved cholesterol but I think most of you know how I feel about the importance of cholesterol in overall health.

So it is a pretty mixed bag but to me the bad outweighs the good:


Lowered short term blood glucose
potential weight loss (could be bad)
Insulin sensitivity increases
slowed gastric emptying
Reduced Cholesterol


Weight increase (odd that some studies showed increases while others showed decreases)
Increased Blood glucose/insulin 180 minutes post prandial
Reduced ability to absorb vital nutriets
Enlarged colon (inflammation diseases)
Many gastro-intestinal side effects

Again I stand by my stance on whole real food vs man made frankenfoods. You cannot cheat your body into thinking it is eating nothing when you are eating something. Eating stuff like this has many effects. It is not like eating a glass marble. It won’t just pass through with no metabolic effects. You can’t cheat the system.
