So how does a starchivore type 1 manage their blood sugars while eating only plant based whole foods?  Earlier this week I kept a record of blood sugars, food, insulin and exercise. Here is the result.

On waking at 5am I check my sugar, 5.1 mmol (92 mg/dl). Pretty good! I eat a sourdough breadroll with some mango jam. Time for the morning walk, a 6km trek around our seaside village, watching the sun rise over the Coral Sea. After the walk my sugar is 4.5 mmol (81 mg/dl). 

At 7am I have my one insulin injection for the day, 6 units of long acting Levemir. Time for breakfast, a large bowl of rolled oats and barley, with some dried fruit, a mango, banana, piece of papaya, flaxseed and chia seeds. After enjoying breakfast I go for a 36km bike ride around Cairns. Back home at 10 o’clock, my sugar is 6.8 mmol (122 mg/dl).

At noon my sugar is a little low at 3.8 mmol (68 mg/dl). Lunch is a potato and green vegetable curry, with 500gm of potatoes, followed by some homemade barley pudding.

At 4pm my sugar is 4.9 mmol (88 mg/dl). I’ll be going for another walk, so need to carb up with a breadroll with honey, and a banana. We repeat the same walk as this morning’s, another 6km. This is the dangerous time of the day, as my sugar usually goes too low. So it is today, 3.4 mmol (61 mg/dl).

The evening meal consists of a hearty barley, celeriac and pea soup, with another breadroll, followed by my favourite dessert – barley pudding. At 10pm my sugar is 6.7 mmol (121 mg/dl). The Levemir action becomes less during the night, and on waking the next morning my sugar is where it started, 5.1 mmol (92 mg/dl).

Total calories consumed during the day is 3467 kcal. Food macros are 696 grams carbohydrates, 93 grams protein, and 37 grams fat. Without intending it to be so, calorie percentages for the macros happen to be 80/10/10.

All this on 6 units of Levemir.

When I was on the keto diet, I needed 1 unit of insulin for every 15 grams of carbs. That would have equated to 47 units of rapid acting insulin. Now I have none. What a difference!

Insulin resistance is the key to the riddle.
