I am very interested in Wigobi, but are the side effects severe?

I am worried because I have gained a lot of weight lately due to a heavy workload and an irregular lifestyle. My stomach, in particular, bulges significantly even after eating just a little, so I became interested in Wigobi.

I became interested after seeing videos recently of celebrities claiming to have seen great results from getting Wigobi, so I looked it up. However, I actually saw an article stating that the effects of Wigobi do not last and that the weight regain occurs. Is it really true that Wigobi is not very effective? I am curious about the side effects.
