I posted this to their terrible story on Facebook:
Please correct the false argument that appears in your article:
“Without [carbs], our bodies will rely on protein, breaking it down for energy instead of using it in its preferred role of growing and maintaining tissues.”
This is NOT what happens. Without carbohydrates, as insulin lowers, the liver begins produce ketones, which are a highly efficient source of energy. As the body becomes better at using ketones, ingested fat or fat stores from the body are easily converted into ketones or used directly by cells. Trough gluconeogenesis, the liver is able to produce the 50g of glucose the brain needs daily. The liver can actually produce much more, but that is not desirable. Protein is not broken down as long as enough protein is consumed daily (roughly 1g per lb of lean body mass), as is evidenced by DEXA scans of individuals who consume NO carbohydrates, but do consume an appropriately moderate (though not overly high) amount of protein.
In other words, CARBOHYDRATE CONSUMPTION IS NOT REQUIRED AT ALL.
