✨ Your First Week of Intermittent Fasting: What You Need to Know!

Hello! This is SimFast, your app for a healthy start!

You've decided to start intermittent fasting with excitement! That's a wonderful choice. But frankly, the first week can be half excitement and half worry. Our bodies need time to adjust to a new rhythm.

Don't worry! SimFast is here to provide you with the 5 most realistic essential tips to make your first week a 'success road' instead of a 'struggle road'. Just remember these, and it will be much easier!

Tip 1. Warm-up is Essential! Start Lightly

If you jump right into a 16-hour fast from today, your body might be surprised. It's the same as having leg pain when you run suddenly without warming up.

Tip 2. Water Bottle Like a Best Friend! Consciously Drink Water

The culprit of mild headaches or fatigue you feel in the first week is often 'dehydration'. And our brain sometimes mistakes 'thirst' for 'hunger'.

Tip 3. Real or Fake? Get to Know 'Hunger'

The feeling we feel as 'hungry' is divided into 'physiological hunger' when we are really hungry and 'psychological hunger' when we want to eat because of habit or emotion.

Tip 4. Meal Time is a 'Nutritional Feast' Not a 'Reward'!

Put aside the thought, "I fasted, so I can eat this much!" What you eat at mealtime determines how comfortable you will spend the next fasting time.

Tip 5. Be Generous to Your Body's Signals

The first week is a time for our body and mind to adapt to new challenges. Anyone can have a little trouble, and it's okay if it's not perfect.


The first week is not a period to do it 'perfectly' but a period to 'adapt' and 'learn'. Don't be impatient and try to practice the tips I told you today one by one.

SimFast will always support your healthy first step from the side! Fighting! 🚀
