Too bad it does not supply us with the information how exactly fructose intake was increased.
Do you have a link to the actual study? (not the science20.com website)
They fed both groups the same diet, with one important exception:
one group consumed a lot of fructose while the other received no fructose.
Did they add fructose syrup?
What exactly did the mice eat?

Here's the article: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2584858/

The diet was 60% fructose. Sounds a bit too much to me, I don't think in reality you could come to such a high consumption of fructose. It's not very good experiment in my opinion, they could've at least have more groups with different percentages of fructose, that would have given a much more complete picture.

60% fructose? (relative to total energy).
Thats unnatural.
If you include fructose from sucrose, you would have to eat guava, pear, apple and watermelon only,
to get to 61% fructose relative to total carbs.

So, to get to that percentage, you cannot eat any fats (nuts, oil) or high protein foods (fish / yolks) at all.
In the experiment however, they used a 60% fructose diet that included other stuff as well, such as protein (18.8%) and fat (5.2%),
which is impossible to get by consuming natural foods.
