Avoid dextrose, sucrose, maltodextrin, and “natural cane sugar.” Magnesium supports over 300 enzymatic reactions, including energy production (ATP synthesis), muscle function, and nervous system regulation. During fasting, magnesium losses accelerate through increased urinary excretion. Eating—especially carbohydrates—triggers insulin release, which signals your kidneys to retain sodium. The right electrolytes won’t break your fast—and they’ll transform your fasting experience from grueling to effortless. Lastly, remember that consistency matters more than perfection.
When you’re in a fasted state, the two most important things to look for in your drinks to determine whether they are fast-friendly are calories and carbohydrates. This is where your reason for fasting will play a role in your decision-making. If you’re fasting to promote autophagy or you want to rest your gut, then you need to avoid drinks that contain any calories at all, and drink water instead.

You can flexibly choose an eating window that suits your personal schedule, such as from 10 a.m. To 8 p.m., as long as you maintain a continuous 16-hour fasting period.
Together, you can create a plan that is appropriate for you and any health conditions you may have. It’s probably not realistic or healthy to try to lose weight in your tummy in 7 days.

During autophagy, your cells check all their internal parts, find anything that’s old, damaged, or functioning poorly, and replace them with shiny new versions. The old parts are either recycled into new materials or destroyed. At this stage of fasting, you may also enjoy a boost in brain-derived neurotrophic factor (BDNF).
