Do you get low blood sugar, or a lack of energy, or any other negative physical effects? How long does it take you to get used to one meal a day?
Some people have only one meal a day during Lent, and I'm wondering how it goes from a practical perspective.
Personally for me it took very minor adjustment. I was used to eating breakfast right upon waking. I just had to push through that uncomfort for that first morning. I wasn't starving. It was more that I just wanted the dopamine rush.
Now I just drink a bottle of cold spring water when I wake up. Sometimes I have a coffee, tea, flavored sparkling water, or kombucha.
I see negative side effects if I don't eat a balanced meal for that one big meal. It's important that I get fats, protein, and carbs in the right proportions. Otherwise I will crave the macro that I'm missing.
I also see much more obvious negative side effects if I eat poorly like if I eat fast food. I really feel it in my gut and regret it alot more than when I used to eat 3 meals a day + snacks etc. For example if I fast from the previous day and decide to eat some trash food I will have to go to the toilet immediately becuase my body is like "oh heck no what is this get this out now I didn't wait 24 hours for this I'm bout to squirt this mess".
On rare occasions, it's extremely difficult to not replenish myself after exercise which I normally do in the evenings, but I dont do alot of strenuous exercise. If I do feel malnourished from unusually high energy expenditure, instead of having a 'full meal' I'll have a nutritional shake or a nutrition bar.
I keep things like nutrition bars, dried fruit, nuts, etc at the house in case I feel like I'm getting unbalanced. I only use them to regain homeostasis. Or if I have something to do that requires alot of energy first thing in the morning ill eat a nutrition bar and have a coffee. Not every morning. I just use all of this supplementally.
The heaviest part of my workload is done between 1-7pm. Everything else is very light work mostly sedentary and driving. Water is fine. 10/11am-3pm I use my reserves to operate my body (I wake around 10/11am). Around 3-4pm I'll start to get hungry so I take a break and refuel with the one big meal. Then for the next 3 hours or so I finish work.
If I have a snack it's something very light and something that is an addition to what I was missing in the big meal perhaps because I was rushed or couldn't find a way to complete it. Ideally no more intake after 8/9pm, other than sips of water. Key word sips otherwise I have to get up to pee multiple times which ruins my sleep. I get the best sleep if I don't consume anything 4 hours before lights out which is around 1am for me.
I don't have an exact system but I try to eat one big meal around 3-4pm-ish 90% of the time. I will occasionally break the cycle and I'm not perfect so I will overindulge or have moments of gluttony outside of my usual pattern once or twice a week. I for example am a recovering alcohol abuser so when I get strong cravings to drink I will treat myself to ice cream.
I can see this being a problem for someone who overexercises, needs to take medication with food, is overweight, has a horrible mircobiome addicted to junk food, has a much different schedule, etc.
I should also mention I do not cook. I don't have time. I get my food fresh every day at the grocery store or some type of health conscious food spot if that's an option depending on where I am. Even places we think of as unhealthy aren't that bad in a pinch. For example Wendy's and Zaxby's grilled chicken salads seem alright and you can get them to add/remove things to make it more complete/nutritious.
