Will I experience a loss of appetite immediately after taking Wigobi?

Maybe it's because I'm getting older, but I'm really having trouble losing weight.
I've tried controlling my diet, but my belly fat isn't going away.
I'm considering trying Wegobi because I think I can naturally lose weight if I control my appetite.
If I take Wigobi, will I not feel the urge to eat at all right away?
I am curious about what kind of effects appear.
