Keith Runyan, a physician with type 1 diabetes, reports that a low-carbohydrate ketogenic approach combined with regular exercise and structured meals has significantly improved his blood glucose stability, challenging conventional management protocols.
Keith Runyan, a physician who writes regularly about his own diabetes management, used his latest monthly update to argue that a very low-carbohydrate ketogenic diet, consistent exercise and tightly scheduled meals have helped him keep his type 1 diabetes in unusually tight control. In the post, Runyan said his approach has reduced his insulin needs, limited symptomatic hypoglycaemia and brought his average glucose and day-to-day variation close to the range seen in people without diabetes.
He described being diagnosed with latent autoimmune diabetes in adults in 1998 after years of weight loss, diarrhoea and rising blood sugar that went unrecognised. He said he initially followed standard treatment and later switched to modern insulins, but still struggled with frequent low blood sugar episodes. According to his account, that changed after he adopted a ketogenic diet in 2012, and later refined it further with more regular meals, exercise and sleep, plus simple calculations to guide basal and bolus insulin doses.
Runyan said his current routine includes lispro and Basaglar insulin injections, metformin, a ketogenic whole-food diet and resistance and aerobic exercise. He reported that during the month covered by the post he had no symptomatic hypoglycaemic episodes and used only a small amount of fast-acting glucose when needed. He also said his body weight was about 67 kg and that his glucose readings were comparable to those of non-diabetic individuals, although he acknowledged that his glucose variability remains above his personal target.
His post also set out the reasoning behind what he calls “insulin load”, a way of estimating how much a meal may drive insulin demand based on carbohydrate, protein and fat content. While that framing is his own, medical references do support the broader point that carbohydrate restriction can reduce insulin requirements in type 1 diabetes, though they also warn that such diets can raise the risk of hypoglycaemia and dyslipidaemia and should be approached carefully. Healthline, a Mayo Clinic treatment guide and a review in Nutrients all emphasise close monitoring, individualisation and medical supervision when people with type 1 diabetes attempt low-carbohydrate or ketogenic eating patterns.
Runyan also used the post to discuss blood ketone tracking, time-restricted eating and his resistance-training routine, which he said now includes lifting work, stair climbing and regular walks. The clinical guidance he cited for exercise broadly aligns with mainstream diabetes advice that physical activity can affect glucose in unpredictable ways and often requires individual adjustment of food and insulin. But major diabetes resources still advise carb counting, regular monitoring and a balanced eating pattern rather than the highly restrictive regimen he advocates.
The post ended where it began: with a defence of a disciplined, low-cost lifestyle that Runyan says has helped him avoid both high and low swings in glucose. He presented the approach not as a universal prescription, but as the method that has worked for him after years of trying conventional care. He also pointed readers to his book and consulting services, underscoring that his blog is part personal diary, part argument for a broader reconsideration of how type 1 diabetes is managed.
