No! Granted, despite some of the names of the flavors of these weight gainers, nobody is going to confuse a glass of one of these weight gainers with an honest to goodness chocolate milkshake. But nutrition companies have made a lot of progress in terms of bringing you cutting edge nutrition that tastes good and won't make you gag or have a strange and unappealing texture. Reviewers rated most of the weight gainers on our list as having good to great taste, and we hope you'll try one and agree.
