Just had a journal rejection on a paper assessing nutrient intake on moderately low carb diets for children. Waited 4 months. Reviewer 1 was employed by General Mills! Reviewer 2 promotes juice consumption to increase fruit and veg intake! Seriously? 😬

One of my favourite graphs - it says a lot about ketones, the poor misunderstood fuel source that is not only safe, but essential for brain development. After only 2 hours without food, newborns and infants default into nutritional ketosis!

So wrong. The fallout of workplace bullying of orthopaedic surgeon for being an LCHF advocate. Silenced for trying to save diabetes patients from losing limbs by removing sugar because he’s “not nutrition qualified”. Serious loss of perspective in this world!
No more. When workplace bullying affects my patient care - enough is enough. It's time to call out the bullies & the problems in our 'not so healthy' system.

Our study on a low-carb diet for type 1 diabetes revealed fraught relationships between patients and diabetes care providers. This distrust could raise risk for a medical catastrophe. If patients feel judged, they may not turn to their MDs at times of need

MOH just can’t see the bigger picture. 5:2 is recommended (despite eating whatever you want for 5 non-fasting days). But paleo and very low carb is not recommended- despite focus on unprocessed whole food all the time. The mind boggles!
