How to gently enter the intermittent fasting mode?

It is generally started according to the most sparing scheme. First, you switch to three meals a day: breakfast, lunch and dinner. No snacks, just water. Frequent eating raises insulin and stops fat burning. As soon as the new regime becomes habitual, you refuse breakfast or dinner. There are 2 meals left. Listen to your body - with the right diet, it will tell you when you can do without food. (But if you left dinner - it should not be too late). The last step is to lengthen the fasting interval and shorten the eating window. The traditional scheme is 16/8 (16 hours of fasting and 8 hours of eating).
