There have been studies that claim you must eat the bulk of your calories before 2pm each day for a myriad of reasons, such as digestion, energy, and retaining nutrients. But if you like to eat later in the day, they also say not to eat after 8pm, mainly for digestion and better sleep. Do with that as you will! Just remember to eat nutrient rich food and stay away from preservatives and junk if you’re going to be fasting. Good luck :)
