Breakfast under 30 g of carbohydrates in type 1 diabetes

Because in the morning your body responds less well to insulin. In the morning, during the last hours of sleep, cortisol and growth hormone rise a great deal. As a result, the liver is driven to release more and more glucose. The same amount of carbohydrates raises blood glucose far more in the morning than at lunch [1] [2].

That is why you start the day at an apparent disadvantage. The second problem comes from what you put on the plate. A classic breakfast means bread, cereal, jam and juice. These contain starch and sugars that are absorbed quickly. To counter the hyperglycemic effect of breakfast, your doctor often sets a tighter insulin-to-carbohydrate ratio for the morning. If you only cut the carbohydrates, however, without adjusting the dose together with your doctor, the risk of hypoglycemia rises a great deal [3].

Almost any of them, because one egg has around 0.5 g of carbohydrates. Two fried eggs with a tomato and a few slices of cucumber stay under 5 g of carbohydrates. An omelet made from two eggs with mushrooms and spinach climbs only to 6 g of carbohydrates. Oil, butter and olives add nothing.

Bread changes the arithmetic, not the eggs. A 30 g slice adds about 15 g of carbohydrates, so the plate climbs toward 20 g and still stays under the threshold. With two slices, however, you go past 30 g of carbohydrates. A meal very low in carbohydrates but rich in protein and fat can still call for insulin, sometimes later on [4] [5]. The timing of the dose is settled with your doctor.

Yes, and with plenty of room to spare. A 150 g pot of plain yogurt brings around 7 g of carbohydrates. A 30 g handful of walnuts, almonds or hazelnuts adds only 2-3 g of carbohydrates. So you have a breakfast of about 10 g of carbohydrates. On top of that, the fat in the nuts slows down the rise in blood glucose [6].

You can put a few strawberries on top, bearing in mind that 100 g bring around 6 g of carbohydrates. Greek yogurt has even fewer carbohydrates, about 5-6 g in a 150 g serving. Watch out, however, for fruit yogurts and flavored ones, which often reach 12-15 g of carbohydrates per 100 g. Better to read the label and add the fruit yourself [7].

You start from the cheese, which brings almost nothing. Feta and hard cheese stay under 1 g of carbohydrates in a 30 g portion, and cottage cheese 3-4 g of carbohydrates per 100 g. Once you also add tomatoes, cucumbers, peppers and olives, the whole plate still stays at 8-10 g of carbohydrates. Olives and olive oil are not counted.

Only bread really moves the total. A single slice of bread pushes the meal toward 25 g of carbohydrates, and two slices take you over the threshold. If you want bread, choose thin slices and weigh them for a while, until your sense of visual estimation develops [8]. Pickled vegetables and roasted peppers add very little, generally just a few grams of carbohydrates per 100 g.

Around 3-6 g of carbohydrates, depending on the vegetables you use. The eggs bring almost zero, so the total comes from the vegetables. A 100 g portion of mushrooms means 1-3 g of carbohydrates, and the same amount of spinach or courgette about 2-5 g of carbohydrates. One tomato adds around 3 g of carbohydrates. The butter or the oil in the pan does not count.

Onion and carrot push the total up faster, at 7-8 g of carbohydrates per 100 g. Grated hard cheese stays at zero. The arithmetic changes, however, with potatoes or corn, which take the omelet toward 20 g of carbohydrates or more. Weigh them separately, because the eye underestimates them easily. As usual, the fat in the omelet can delay the rise in blood glucose [9].

They do, if you weigh them. A 30 g portion of dry rolled oats brings 18-20 g of carbohydrates, that is, most of your 30 g threshold [10]. If you prepare them with 100 ml of milk, you add another 5 g of carbohydrates and reach 23-25 g. With a handful of nuts you go past 25 g of carbohydrates, but you stay under the 30 g threshold.

The trap is to measure out the portion by eye. A generous bowl easily means 60 g of oats, that is, over 35 g of carbohydrates from the oats alone [11]. Honey, bananas and oats with dried fruit push the total up quickly. If you want a breakfast with even fewer carbohydrates, you can use water instead of milk and cinnamon for flavor.

Three options solve almost any rushed morning:

• eggs boiled the evening before, with a tomato — under 5 g of carbohydrates;
• plain yogurt with nuts — about 10 g of carbohydrates;
• feta with cucumber and peppers — around 8 g of carbohydrates, with no cooking time at all.

That gives you a total that is easy to work out, even on the run. The real gain is not the time, but the predictability. When you repeat the same breakfast for a few days, you can watch on the sensor how your blood glucose responds and adapt your insulin doses gradually. Boil six eggs at once in the evening, for several days, and portion the nuts into small bags in advance. That way you no longer improvise in the morning, and it is much easier to decide the insulin dose.

Yes, but it depends a great deal on the amount of milk. Plain coffee, espresso or filter, has zero carbohydrates [12]. The milk is the only source, through the lactose in it. The 50 ml of milk in an ordinary coffee add 2-3 g of carbohydrates, which is very little. An ordinary cappuccino reaches 8-10 g of carbohydrates. The large cups from a coffee shop are the danger, because the amount of milk can be considerably higher.

Plant-based drinks change the arithmetic in both directions. Unsweetened soy milk has 1-2 g of carbohydrates per 200 ml. The sweetened versions and the rice ones can have far more carbohydrates. Flavored syrups and whipped cream add carbohydrates too. If you drink a coffee with milk on an empty stomach, it would be interesting to follow the glucose estimated by a sensor over a few mornings in a row.

The simplest is a box with two boiled eggs and raw vegetables, an option that stays under 5 g of carbohydrates. You can add plain yogurt in a separate jar, with its 7 g of carbohydrates. Alongside it you put 30 g of nuts, weighed and packed in advance. The total comes close to 15 g of carbohydrates. All of it keeps well for a few hours in an insulated bag.

The advantage is that you know the number of carbohydrates before you leave home. When you buy breakfast on the way, a croissant with juice or a large bagel easily go past 40 g of carbohydrates [13]. If you eat later than usual, the timing of the insulin dose changes, and that is something you discuss with your doctor [14]. The box prepared at home gives you better food choices.

Usually yes, if it has enough protein and fat. Eggs, cheese, yogurt and nuts leave the stomach more slowly than white bread or sweetened cereal [15]. A breakfast low in carbohydrates but substantial often holds better than a large one based on starch [16]. How full you feel varies, however, from one person to another.

The glucose sensor can tell you what kind of hunger you have. If your blood glucose falls toward lunchtime, the hunger comes more from too much insulin than from a meal that was too small. You treat the tendency toward hypoglycemia first, then adjust the dose together with your doctor. In children and in pregnancy, reducing carbohydrates remains a decision taken only together with your doctor [17] [18]. Keep a short log for two or three days and discuss it at your appointment.
