I'm a diet controlled type 2 diabetic with ninja contol I follow lchf and have been experimenting with what to eat before a run. If I run fasted then my bg stays level but not sure my performance is as good. If I have 100g of strawberries and a mug of bone broth then my running is easier but my bg at least doubles during the run.
Are there any other lchf runners who have found what works for them to fuel runs. Am going to try the park run fasted tomorrow and then next week try a helping of carbs,around 30g (this is my whole daily total normally) to see how that goes.
