Recommended In March 2026: How About The Eight-day Diet In The 21-day Diet?

In fact, I’m particularly annoyed by articles that give you a quick start from the very beginning.

"Twenty-one days, complete rebirth!" "Persevere for three weeks, and I'll give you a brand new self!"

Pooh.

That number called twenty-one sounds like bone fragments that have been chewed repeatedly and spit out by marketing accounts.

But if you really search it, you will find that it is not completely unreasonable.

Some people claim that a plastic surgeon noticed that people who underwent amputation took 21 days to adapt to their new physical condition, and that this habit gradually formed.

However, it is easier for me to conclude that what I heard seems to be true. However, the 21st is just enough time for the uncomfortable thing you are about to deal with to become less uncomfortable. It is also just enough time for you to notice that the belt around your waist is indeed a buckle loose when you look at yourself in the mirror.

Day 1: Sober from hunger

Today is your first day to quit milk tea.

At three o'clock in the afternoon, the familiar feeling of sleepiness emerged on time, and my fingers naturally moved to open the takeout app.

You looked at the cup of Bobo milk tea on the screen, your throat moved, and you swallowed a sip of saliva, then locked the screen and placed the phone on the table.

At this moment you feel very tragic.

In fact, there is nothing tragic about it.

I’m just tired of having to find the angle every time I take a photo, and having to spend half an hour retouching the photos. I’m tired of the zipper in the fitting room in malls always getting stuck between my thighs.

The most difficult thing about the first day was not hunger, but greed.

That kind of heart-wrenching greed.

You begin to understand why weight loss videos talk about "distraction," and it's because attention, if you don't let it go elsewhere, is firmly fixed on the refrigerator door.

Day 7: Numbers on scales can be deceiving

You step on the scale and hold your breath.

The number jumps around a few times and finally settles at a lower level than you'd expect.

You can't believe it. When you come down and go up again, it's still the same number.

You almost cheered, feeling like you'd already won.

But what you don't know is that among the four or five pounds that have fallen off, the actual fat that should be lost is probably only one or two pounds, and the rest is all water.

The glycogen in the body ran away with the water, just like when you wet the bed as a child and soaked a large area, there is actually no substantial loss.

But so what?

If the number drops, it means it has dropped. Even if it is an illusion, it is a beautiful illusion.

Day 14: Plateau of Self-Doubt

Suddenly it stopped falling.

The numbers on the broken scale were as if they were welded together, not moving at all.

You begin to wonder, whether you have been starving in vain for the past two weeks, whether you have the unlucky physique that makes you gain weight even if you just drink water, and whether those who post comparison pictures on the Internet are all shills.

You even thought about giving up and ordering fried chicken to soothe your wounded heart.

etc.

Do you know why your weight doesn’t move?

Because you fell too fast, your body was scared.

There is such a skin that has been with you for decades. It feels that you are experiencing famine, so it begins to desperately reduce consumption in order to preserve the little fat that is used to save its life.

This is not because you have failed, this is because your body is messing with you.

What the mouth needs at this time is not to become more hungry, on the contrary... to eat more reliable carbohydrates, or to increase some exercise, and tell it: Don't panic, it's okay, I'm just trying to make you look better.

Day 21: End or Beginning

On the morning of the twenty-first day, you put on the pants that were stuck on your thighs.

The zipper was so smooth that you were stunned for a moment.

You turned back and forth in front of the mirror twice, tying and untying the button that made the seal, like a child who just got a new toy.

Three weeks ago, 21 days seemed like a lifetime to you.

Now you find out, that's it.

Got through it.

But what next?

This is the most cunning place.

The most serious scam of the 21-day weight loss method is not that it is ineffective, but that it causes you to have the idea that all problems can be solved in 21 days.

When you return to the way you used to eat, those pounds of meat will come back with interest, far more ruthlessly than your predecessor.

What really matters is not these three weeks, but the fourth, eighth, and twelfth weeks. When you no longer need to clock in, there is no supervision by others, and no one gives you likes, whether you can still remember the mood you felt when you looked in the mirror this morning.

For those who want to try it

If you really want to try it, don’t follow those desperate fasting methods on the Internet.

Doctors from Xiehe said that the daily calories should not be lower than your basal metabolism.

Girls, calculate: 655 plus 9.6 multiplied by weight (kg), plus 1.8 multiplied by height (cm), and then subtract 4.7 multiplied by age. If you are below this value, you are desperate.

Prepare chicken breast, brown rice, and broccoli, and buy some chia seeds soaked in almond milk for a snack.

Change the order of eating: eat vegetables first, then meat, and finally eat the few bites of rice.

Drink plenty of water, calculated as body weight

Weigh yourself on an empty stomach every Monday, Thursday, and Sunday morning. Do not weigh yourself every day, as this will drive you crazy.

Also, if you are really hungry to the point where you feel dizzy and your hands are shaking, go ahead and eat.

Life is more important than thinness.

The last thing I want to say

Is 21 days enough to form a habit?

Enough and not enough.

66 days may be the real threshold for a new behavior to become "subconscious".

But so what?

There has to be a beginning.

You don't need to think about this too sacred, just treat it as an experiment and play a game with yourself.

It’s best if you win, and it’s no loss if you lose.

After all, there is not much in this world worth persisting in except life itself.

And making yourself live a more comfortable and beautiful life is probably the least laborious thing among them.

Don't have late-night snacks tonight, go to bed early.

You'll thank yourself tomorrow morning.
