Foods that are high in protein, such as lean beef, cottage cheese, tofu, and soybeans, can increase glucagon levels. While glucagon is primarily stimulated by low blood sugar levels, protein intake also triggers its release. This is because protein digestion stimulates the release of glucagon from the pancreas, which in turn helps to regulate blood sugar levels and promotes satiety.
The information from the sources above primarily focuses on increasing GLP-1 levels, a hormone that helps regulate blood sugar and promote satiety, with similar effects to glucagon. The foods that are known to increase GLP-1 levels also tend to be those that are high in protein, fiber, and healthy fats, such as whole grains, fruits, vegetables, and lean proteins.
Additionally, research suggests that a high-protein diet may naturally reduce appetite by increasing glucagon levels.
While the specific mechanisms for increasing glucagon levels through diet are still being studied, it's clear that consuming foods rich in protein, fiber, and healthy fats can positively impact glucagon and GLP-1 levels, contributing to better blood sugar control and promoting a feeling of fullness.
