Not really. I've ran it several times and have lost negligible amounts of strength. Any drop in strength was just due to lack of energy from glycogen/slight dehydration - as soon as I did the refeed I was back to normal.
I've actually made strength GAINS on UD 2.0. The ridiculous energy levels that came from doing the refeeds let me break through several sticking points that I had.

No gym for home, work out floor with 30, but is it for 20 like 30 lb when you no lift it to be for men, for 30 lbs instead? or half is 10 for 20 pounds?
