Not a good news for keto according to this new study.

My thoughts on this study:

- There is not enough information on that link for any of us to have a clue what was actually going on

- 17 men on 50% carb diet for 4 weeks, and then switching to 5% carb for the next 4 weeks? Not enough people. Too short, and goodness, it would take me more than 4 weeks of keto to recover from how dreadful I would feel after 4 weeks of all that carb.

- here is a link to an article on NuSi describing the design issues and disagreements the organisation encountered.

- ‘isocalorific’ diets were used. An isocalorific diet is a diet where the fat, protein and carb percentages are strictly controlled, but what those percentages are made up of, is not important. So basically you can eat processed rubbish, but so long as it fits your macros, you think you are doing great. Milk chocolate? Salad? Donut? Steak? Weetabix? Vegan cheese? Banana milkshake? Polyunsaturated veg oil? Lard? Coconut butter? Chicken nuggets? Huge salads? Processed tinned bean salads? Turkey Twizzlers? Organic shoulder of lamb? Battered fish, deepfried in soya oil?
So long as the macro quotas are met, you can eat what you like.

My experience:

- so long as I avoid the gluten and carbs that cause my autoimmune inflammatory issues and so long as I eat minimal carbs, then my inflammation is massively reduced. My cholesterol is great. My blood glucose is under control. I feel well. None of those would be the case on a 50% carb diet. I know this because adding carbs to my diet makes me feel progressively more grotty the more carbs I eat.

I understand the issues posted above about the study. However, my personal experience after changing to a keto Dr Bernstein diet immediately after being diagnosed with diabetes, is that I found myself three months later with a total cholesterol of 10 mmol/L, high inflammation markers and even though I was eating less than 30 g of carbohydrates a day, I had almost zero ketones on my blood ketone monitor on waking and I was putting on abdominal fat. After an enormous battle with my diabetes specialist (who would only read medical articles referenced through the Lancet) and who always wanted me on insulin with my low c-peptide (even now though my blood sugars were now impaired rather than diabetic) and now statins, I was given another 3 months grace. I found that through counting my cholesterol (200 mg a day maximum) and intermittent fasting that I managed to normalise the changes. I'm happy to say that my diabetes specialist is now supporting my efforts.

What do I think is going on here? I think I'm thin type 2 rather than type 1 which I was diagnosed as. Thin type 2's can't generate enough new fat cells, which causes sugar to be dumped into the bloodstream, which switches off fat burning even on a keto diet. Dr Fung's books suggest intermittent fasting is the key and anyway, he explains the process much better than I have. So my experience could be unique to thin type 2's or whatever type of diabetes I am (there are supposed to be over 40 types) and certainly not everyone, particularly after reading the comments above.
