For women with gestational diabetes, eating either a lot or a little carbohydrate in the morning can both keep blood sugar levels within a healthy range more than 90% of the time, meaning both approaches can meet recommended blood sugar goals even though they affect glucose fluctuations differently.

For women with gestational diabetes, consuming about half of daily carbs in the morning lowers average blood sugar levels compared to eating only 10% of carbs in the morning, but it also causes greater fluctuations in blood sugar throughout the day.

In women with gestational diabetes, eating most carbohydrates in the morning instead of later in the day does not change total daily calories, carbs, or protein, but is linked to consuming about 9.9 grams more fat per day, which could affect metabolic health.

For women with gestational diabetes, eating most of their daily carbohydrates in the morning leads to lower insulin resistance compared to eating most carbohydrates later in the day, as measured by a standard blood test.

For pregnant people with gestational diabetes, eating the first meal of the day before 10:56 AM is linked to lower blood glucose levels in the morning and during the night compared to eating later.

For pregnant individuals with gestational diabetes, eating the first meal before 10:56 AM does not result in lower daytime blood glucose levels compared to eating later. The timing of the first meal appears to affect blood glucose levels during fasting and overnight periods more than during the day after meals.
