Yes it is.
Once a week, I eat a buffet which averages about 2000 calories.
I love fasting. It allows my body to drop insulin levels to a new low. And when your insulin is low, you know what happens, right? Your body burns fat like crazy.
Say I wake up at 5am. And don’t eat until, 12–1pm. Where does the fuel comes to sustain me for that 7–8 hours?
From my body fat:)
Now there is a caveat to this.
Firstly, if you diet is high in carbs, you will have tons of glycogen reserves in your liver and muscle which needs to be burned first before your body starts to tap into your fat reserves.
The process is much complicated than that actually, and overall what fuel (sugar or fat) your body burns is dictated by your insulin and leptin levels & their sensitivities.
Now, coming back to the point, is it possible to eat once a day and still stay healthy?
Yes, according to Ori Hofmekler. His book ‘The Warrior Diet’ is the reason why I started intermittent fasting in the first place. I urge you to read it.
Honestly speaking I found eating once a day to be inflexible.
Ori’s divide one’s day into periods of underrating and overeating.
During undereating you not allowed any food that is too taxing to the body like diary, oils and fats, sugar etc.
So you sustain yourself by fasting (however you can have black coffee, soft boiled egg, whey concentrates, sprouts etc if you feel really hungry) and then when the sun goes down, its time for a FEAST:
But he insists to be careful when breaking your fast.
“Always start with salads and then move to proteins. Only then you can have your carbs etc”, he says.
So if you maintenance calories is about 2500 and you need to gain weight, you can have a meal which gives you about the same number of calories.
Personally, if I going for a buffet, I want to eat my heart out. Overeating is in our DNA we cannot help it right?
Eating 2000 calorie meal is not alien to me, and I frequently enjoy these extravaganza from time to time, allowing me to stick to my super healthy diet plan.
Now, you can get about 2000 calories from a MC-Donald meal too!
Therefore you need to make sure that about most of your food is highly nutritious and not empty calories like pizzas or burgers!
I also urge you to go into this kind of eating pattern slowly.
If you are eating 4 to 5 meals a day, cut down slowly to 3 and then 2.
