@liveleantv: A 24-hour fast creates a stronger metabolic shift than shorter fasting windows. Insulin drops very low, glycogen stores are largely depleted, fat burning increases, and ketone levels rise. This can also increase signaling related to cellular repair processes. But there’s a trade-off. Longer fasts can make it harder to maintain training intensity and protein intake, both of which are important for preserving muscle. Fasting can be a useful tool, but more stress isn’t always better. #fasting #intermittentfasting #fatloss #fitnesseducation #longevity
