You shouldn't consume diet drinks during intermittent fasting because they can trigger an insulin response, disrupting fasting benefits.
Even though diet drinks are low in calories, they contain artificial sweeteners like aspartame or sucralose, which can stimulate insulin release.
Insulin helps regulate blood sugar levels, but its presence can halt the fasting state, inhibiting the body's ability to tap into stored fat for energy.
Additionally, the sweet taste of diet drinks may increase cravings for more sweet foods, potentially leading to overeating during the eating window.
Water, herbal tea, or black coffee are recommended during intermittent fasting to prevent disturbing it and maximize its metabolic health and weight reduction benefits.
These beverages are calorie-free and do not trigger an insulin response, allowing you to stay in a fasted state and reap the rewards of intermittent fasting.
