Diet pill? 47.5-40

I have a friend who is 86 and has gotten me to order some Red Ruby Oil capsules for him as he has read their advertisements that promise it will dissolve belly fat. I did but I think it's a scam, especially after reading the reviews on Amazon. Anyway, I asked the I Ching, "What effect will Joe get from taking Red Ruby Oil. I got 47.5 - 40 : Oppression leading to Release. I'm thinking the belly fat is the Oppression so perhaps this oil will lead to its Release after all. The line seems to say it will take time (the ads say it works slowly) and perhaps the bit about making "offerings" could refer to giving up fattening foods along with just taking the pill - so that's very hopeful! But I also can read these hexagrams as meaning he has been fooled, Oppressed, and slowly he will come to realize this and thus he will be Released from this deception.
Any ideas?
Thanx!
