A low carbohydrate diet can lead to a temporary increase in cortisol levels, particularly during the first three weeks of transition. If sleep remains unaffected, there's generally no need for concern regarding cortisol spikes. For those feeling more stressed after switching to a low carb diet, it's important to monitor how you feel beyond the initial weeks to determine if the diet suits you. Exploring starchy carbohydrates at dinner may also be beneficial for sleep quality.
