If I start Wigobi, do I not have to force myself to reduce my rice portion?

Reducing my food intake is the hardest part whenever I go on a diet.

It is hard to endure being hungry, and
Whenever I try to eat just a little and stop, I get hungry again not long after.

If you look at the reviews for Wegobi, there are many people who say that their food intake naturally decreased.
I became curious about what it actually feels like.

Whether the amount of food consumed changed noticeably when first using it
Or I wonder if it tended to change little by little.
