The day before a fast is important to keep your body hydrated, well-nourished, and away from caffeine and alcohol. I hate to beat a dead horse, but it is really that important to get lots of water the ENTIRE day before the fast, not just the last hour.
You should also eat throughout the day well-balanced meals and snacks. My recommendation is to start your day with a nice hearty breakfast such as 1-2 eggs, a slice of whole-grain toast and a banana. For a morning snack try yogurt and fruit with granola; or a protein smoothie. For lunch try a vegetable pasta salad with a scoop of tuna or cottage cheese. Enjoy a fruit with some nuts or peanut butter in the afternoon and then get ready for dinner.
The meal before Tisha B'Av is called the Seudah Hamfseket, but that won't be dinner. Fill your tummy with a nice solid meal like this one below before the Seudah Hamfseket.
This salmon recipe is super easy and delicious loaded with good fat and protein to prepare you for a fast.
Lentils and rice are the perfect carb combo for your prefast meal and pair so well with this tart flavored salmon.
Serve some green veg on the side, this asparagus with a walnut topping gives you a little extra fat to sustain you through the fast.
End your meal with a little something sweet made from dates. Dates are high in potassium which is good for you before a fast. If you don't like Date Balls, try Date Pinwheels, Dates with Almond Paste, or Raw Date Brownies.
Wishing you an easy fast.
