Is there any pre work/energy drinks you can take during a fast.
I have gamer subs and it claims to 0 in everything so I’m curious if it keeps the fast.
Also wonder if reign energy drink is safe as that was my go to when doing keto.
Any recommendations or advice appreciated
7 days without food seems very extreme to me and I don’t think you should be attempting this without consulting with a licenced medical doctor. This could place a major strain on your heart and other organs and could result in death. It probably won’t, but it could.
Why do you think that depriving yourself of food for seven days is the ‘answer’? What is the problem that you’re trying to ‘fix’?
I’d also argue that what you’re planning isn’t ‘intermittent fasting’, it’s actually extended fasting and you’re posting in the wrong subreddit.
for pre-work, being fat adapted or metabolically flexible is a big benefit, and having experience with some multiday fasts before jumping into a 7 day would be helpful. at a minimum it might be a good idea to reduce carbohydrate for the 3-4 days before the fast.
energy drinks are in general not good for you. many people say that artificial sweeteners may have some effect on insulin, if not glucose, and could derail you from the fasting state (personally for me, this has been negligable if not non-existent, though i have no way to measure insulin directly). typically the rest of the ingredients are not so great either (im not sure about the specific one you mentioned), and energy drinks just aren’t necessary really. if you’re addicted to caffeine (which is the only thing in (zero calorie) energy drinks that actually gives you energy), you can get it from a much better source.
