I wonder if you'd allow me to put right a misconception that's arisen from the start with this question.
The link provided by cazzz1975 does indeed discuss sprouts, but these "sprouts" are the newly germinated shoots arising from seeds. Alfalfa is the typical example, but as the article implies, many seeds form nutritious shoots which are perfectly edible. The article has been written by an American and the discussion on broccoli sprouts is a bit misleading as it refers to what we call broccoli florets in the UK, which are not sprouts in the true sense.
Brussels sprouts on the other hand come from a plant that is totally different species from the likes of alfalfa. Brussels sprouts or Brassica oleracea are a member of the cabbage family and bear no comparison nutritionally to any form of sprouting seeds or bean.
As far as the total lipid content goes, I'm sorry to say that the figures given so far have been over the top. The reality is that each 100 grams of raw brussel sprouts contain less than half a gram of total lipids. One of the standard sources for data of this sort is the USDA database which has been available online for a number of years. Here's the link:

Use as a keyword "brussel sprout", select the bottom option (raw sprouts) and 100g on the following page although you can check the others too. This total lipid content should not be treated too seriously as many of the lipids and associated fatty acids in the total figure do not all play a part in weight gain.
