Are the "BMI-reducing / Strong" green teas actually effective?

I've always see these green teas(and couple of other drinks) in Japan, that lable to reduce subcutaneous fat, reduce BMI and visceral fat(the reason i would consume it too for) - brands like Ayataka deep green tea, Suntory Tokucha, or Ito En Koi-cha.
From what I understand, they are highly concentrated and packed with way more catechins/EGCG than regular green tea.
My current routine is super clean, I actually only drink water (no coffee, alcohol etc...) and wont be using this to replace other unhealthy drinks. I am considering to add it for my weigh-loss ruitine so was wondering if it is worth it, or is it better and healthy not to drink it at all, as it is super high in caffeine and catechins.
