Tag: Protein fatigue

According to a 2019 study, consuming large, protein-rich meals, especially when paired with carbohydrates, can increase feelings of sleepiness. The common experience of wondering, 'Why do I feel sleepy after eating protein?' is rooted in several metabolic and physiological responses that occur during digestion.

According to research, the phenomenon of feeling sleepy after a meal, known as postprandial somnolence, can be influenced by the type and quantity of food consumed. While often associated with carbohydrates, eating a lot of protein at once can also contribute to this feeling of tiredness. This happens due to the body's complex digestive and metabolic responses to a large protein load.

According to research from the National Institutes of Health, while some fatigue after eating is normal, the composition of your meal significantly affects your energy levels, with both high-carb and high-protein meals causing different degrees of post-meal drowsiness. If you feel specifically tired after eating protein, several physiological factors could be at play.

While the term 'protein crash' does not refer to a scientifically recognized medical condition akin to a sugar crash, an unbalanced, high-protein diet can lead to symptoms of fatigue. The perceived crash is a misinterpretation of underlying issues like dehydration, digestive effort, or other nutrient deficiencies.

According to a study on postprandial somnolence, the feeling of sleepiness after a meal is a common phenomenon with several contributing factors. If you often find yourself wondering, "Why do I feel lethargic after eating meat?", it's likely due to a combination of hormonal responses, the energy demand of digestion, and other dietary factors.

According to a 2024 study, higher protein intake was associated with a reduced likelihood of reporting sleep problems. Despite this, many individuals experience a midday slump after a protein-heavy meal. The question, "Does protein cause tiredness?", involves a more complex relationship depending on factors like meal composition, quantity, and individual metabolism.
