My typical suhoor when I fast this time of year is a nice big smoothie!
-Protien powder w/ 25-30g of protien per serving
I usually make this pretty big to make up for the fact that Im not drinking water through out the day, but since its getting to winter Im not as worried about getting in a ton of liquid in the morning.
I would also say if you have a bigger appetite that adding some toast or a bagel with definitely help, and you can make it an avacado toast for added fat. I tend to do this when its getting to summer since my fasting period gets up to the 15-16hour range. I also up my amount of liquid then, usually trying to get in about 1.5L during the night at least.
Also please dont forget your multi! With a shorter eating window it can be hard to get in our nutrients, and personally I would prefer to spend my time trying to get in my carbs, protien, and fat over worrying a out micros.
Also if you use a plant milk make sure its calcium fortified! Especially if your a teenager since calcium deficiency will be .much worse for you than for fully developed adults.
Also note that Im not an active person, and I have a carb and fat heavy dinner. But hopefully this gives you guys some smoothie ideas to keep you full during shorter fasting days!
