Technically, consuming anything with calories can break a fast. However, a minimal intake of 15 calories is very unlikely to significantly impact the metabolic state of fasting or negate its benefits. For most people, especially those following intermittent fasting for weight loss or metabolic health, such a small number isn't enough to disrupt the fast. It's important, though, to monitor how your body reacts and adjust accordingly to maintain your fasting goals.
