Growing up sort of poor-ish, I have noticed that a lot of my eating habits are basically not far off Dickensian "Eat now, you might not have anything at all tomorrow" patterns.
The idea that we need to eat 3 times a day is from a time most people were living an agricultural life, or doing heavy physical jobs. If you burn a lot of energy, you don't need to be told to eat more.
The idea that we need to eat 5 small meals a day to stay healthy, and never skip a meal! is first world bullshit.
If you have already done this, you will have to enter into a period of building exercise and adding muscle weight back onto your body before your metabolism will work the way it should.
Sure, this is anecdotal but I was eating 1600 calories a day OMAD and my metabolism dropped to burn 1850 calories a day. (As measured by a VO2 Max machine as part of a dexafit scan), which is about 750 calories a day under what it should have been. My standing body temperature was also hovering around 97.3 instead of 98.6
Since then I've been eating more, closer to 3000 calories a day and exercising with heavy lifting 3x a week and my metabolism has come roaring back. I haven't had another VO2 Max scan but my standard morning body temp is now 98.3. In the months I've been doing that I have gained 1 pound, but I am sure a good chunk of that is muscle.
You wont ever starve if your meal is 700kcal one day. You will want to eat more the next day, your head will tell you. Or maybe you want some ice cream after in the same window?
On the other point, very few people who sit around all day need 2000kcal, unless they're relatively huge in any dimension. Either way you will find out if you count for a couple of weeks and if your weight is constant your average intake is your TDEE. If you're sedentary my bet is it's less than 2k.
I feel so much obesity is down to people thinking 2k or even 2500kcal is right for them despite an activity level that means they might be closer to 1500kcal-1800kcal.
Absolutely concur with your advice to count for a couple of weeks, and I'd back that bet...
I'm trying to bulk now and the online calculators I'm using are telling me to take in 3,100 calories, which feels like way too much.
But I am 6'3", 195 lbs, and I'm hitting the gym 5-6 days a week, so maybe?
After years of dieting and weight loss it's hard to eat that much.
But your experience will vary massively depending on how active you are, including how hard you hit the gym.
It's not impossible it's right, but really just count for a few weeks and keep track of your weight, and then adjust up/down up to a few hundred kcal until your weight is changing the way you want it tp.
Unless you're super-lean there's very little reason to add more than 300-400 kcal above maintenance at most (I do less these days) - big bulking cycles take a lot of discipline to break out of. I generally favour slow but steady these days as I'm back into lifting.
Age also factors in - you can expect slower progress the older you get and accordingly you'll need fewer extra calories if you want to avoid adding fat. Conversely, if your testosterone levels and metabolism are at their peak, you might well burn more.
Counting and tracking is really the only thing that will tell you the right numbers for you.
Could have been a psychological illusion, but there you go.
Wordly people eats twice a day,
Ascetics eats once a day,
Children and invalids eats throughout the day.
The tricky part for me wasn't getting enough calories, but ensuring I'm getting a good amount and a good variety of nutrients.
I try to eat healthy meals most of the time, but even a handful of "cheat" meals per week to indulge my cravings for tasty, non-healthy food can seriously throw off my overall nutrition profile for the week, since I only get 7 of them.
I've been trying to balance for that by drinking a bottle of Soylent after every unhealthy meal, basically as a nutritional supplement.
The main difference its energy levels. Before it was like a roller coaster of 10/10 minutes after eating, then going low to 5 or 4 in a few hours. With fasting, it's more like a consistent 8/10 across the day.
The main challenge with OMAD, it's probably the social aspect, eating it's rarely around calorie consumption.
Bonus: Is practical only having to do clean kitchen utensils and dishes one time per day. Lot of time saved.
Motivation is never something to overcome. Motivation is power. You work with it.
By "willpower" people usually mean ability to force yourself to do something you aren't motivated to do - you shouldn't try to do that, it's operator error of the human system.
Fear of spiders and snakes were found in infants.
Reflexes are instinctual.
I think we have a few instincts.
The problem with claiming that humans have instincts is that it gives cover for bad theories of mind. For instance, the Nazis believed Jewish people have Jewish minds and German people have German minds; many Marxists have held that bourgeoisie have bourgeois minds. In reality, the human mind is a blank slate, in terms of knowledge and beliefs.
Sedentary people definitely don't need more than one meal a day to survive. It's trivially easy to satisfy daily calorific and nutritional requirements in a single sitting. There are still a lot of people who say breakfast is the most important meal of the day. It is if you are going out to do 4 hours of manual labour in the morning before lunch. Not so much if you only cycle a few miles to work then sit down (and that's already more exercise than most do).
However, I do think there is a difference in how people react to fasting. In particular I think fasting is better for men than for women. I've been fasting regularly for more than 10 years at this point and it's great. But all women I've known to try it have had problems with it.
At the lowest point I had lost a lot of interest in food and eating and did not have the same hunger. It is much worse problem since loosing weight is only about discipline, but gaining weight is about more than that.
When I’m in the office, I crave a sandwich from the pizza place across the street A) because it’s there and B) to kill the monotony of being in my office.
At home I have a far easier time skipping lunch despite there being snacks everywhere.
A different way to look at it would be that a lot of Western people are too sedentary for more than one meal a day. Not only are they getting fat, their muscles are atrophying from lack of activity.
