24 hour fast

Hi Brooke,
I would like to try a 24 hour fast. Do I eat a larger then normal ‘last meal’ or just eat like I regularly would? Any other tips?
I also want to have the option to sip bone broth and bought one from a health food store but wanted to make sure it will be ok. Bone Broth Chicken Protein from PrairieNaturals; Ingredients: Organic, Free-range chicken bone broth protein powder; 60cals, 0g fats, sugar, carbs and 14g protein, 200mg sodium. I’m a bit worried about the fact it says protein powder, but the lady at the store said it was the same as making bone broth so I thought I’d just double check with you. Thanks!
