Answer:

You should not skip breakfast. It deprives your body of the energy it needs for normal function. Skipping breakfast causes low blood sugar and excess insulin release. Over time, this impairs the function of the pancreas's beta cells. Consequently, insulin resistance increases in people with type 2 diabetes, leading to impaired glucose tolerance and blood sugar fluctuations.

Lack of glucose from breakfast can cause fatigue, weakness, insomnia, poor concentration, and hypoglycemia. Skipping breakfast can also lead to intense hunger and cravings, making you want to eat more at lunch and dinner. Consuming large amounts of food at once can cause obesity, negatively impacting blood sugar levels.

A nutritious breakfast can lower fasting blood sugar, A1C levels (average blood sugar over 2-3 months), and weight. A low-carb breakfast helps reduce glucose spikes and maintain stable blood sugar levels.

You should eat breakfast before 8:30 a.m. because this is when your body's metabolism increases, blood sugar levels are lower, and insulin resistance is less prevalent.

Your breakfast calories should account for 25-30% of your total daily energy intake. People with diabetes should limit intermittent fasting, including skipping breakfast. Excessive dietary restrictions should be avoided, as they can lead to energy and nutrient deficiencies. Instead, prioritize low glycemic index (GI) foods to ensure adequate nutrition and prevent sudden blood sugar spikes. Avoid overeating and divide your meals throughout the day to balance nutrition and control blood sugar. Reduce processed carbs, increase fiber intake, and choose plant-based fats and lean protein.

Drinking two liters of water daily boosts metabolism and enhances insulin's ability to regulate blood sugar. Combining this with morning exercise increases alertness, improves physical fitness, and controls appetite.
