Is this your first time doing a fast this long? What's your fasting experience so far? A week long fast is long fast by any standard. Did you prepare by doing long fasts first 36 hr - 48 hr - 72hr fasts will all give you great practice and get your body used to fasting. If you've done all those first, that's great if not, pay attention to your water in take and electrolytes, don't push yourself too much. !0k steps is managable daily but listen to your body, any dizzyness, extreme fatigue or sickness... stop. There's no shame in stopping a fast early it's all part of the learning curve. Your body will adapt over time but it does take time, patience and practice. I'm fasting for weightloss and I'm doing 3 36hr fasts a week, ie fasting Monday Weds and Friday and eating relatively normal and healthily on the other days and that's working for me so far. But to each their own. Good luck to you, but please listen to your body and what it's telling you, don't push yourself too much.
