38. Your Brain on Birth Control - with Dr. Sarah Hill

Sweeteners

Non-caloric sweeteners can significantly impact our body's metabolism and cravings. Sarah Hill explains that these sweeteners can create a mismatch in the body, where it prepares to metabolize sugar that never arrives, potentially leading to increased cravings for high-calorie foods 1. This phenomenon was observed in studies where participants consuming diet drinks showed a higher tendency to choose sugary snacks over healthier options 2.

It really does change your threshold for sweetness in a way that promotes the overconsumption of sweet foods.

Hill suggests that reducing sweetener intake gradually can help recalibrate the body's sweetness threshold, ultimately leading to healthier eating habits 3.

   

Behavior

Dietary choices, influenced by external factors, can have profound effects on long-term eating behaviors and health outcomes. Hill discusses how inflammation, often exacerbated by poor dietary habits, can decrease impulse control, leading to a cycle of unhealthy eating behaviors 4. This cycle is further complicated by the use of non-caloric sweeteners, which can create an artificial energy crisis in the body, prompting increased calorie consumption 5.

The things that we tend to do when we're feeling impulsive, like eating a bunch of junk food, promote inflammation.

Hill emphasizes the importance of clean eating, which can help break this cycle and promote healthier cravings, potentially influenced by changes in the microbiome 6.
