I think you'd probably spend more time on trying different varieties of food and different ways of making it.
Twenty percent of whose knowledge? Lyle's? The average dieter? Percentages are relative.
If any lesson is to be learned from the Pareto principle and other power law distributions, it's probably that for all the people trying to lose and keep off a substantial amount of weight/fat, very few will get it off and keep it off no matter how much knowledge they've accumulated and effort they've given. I'd imagine there's also a linear correlation between those successful few and their outlier genetics and/or drug usage. Probably more the latter since genetic freaks usually don't end up obese. Although, anyone with an a voracious appetite and lack of activity could eat past their genetic advantages. It happens to retired athletes all the time.
If anything, the key to long term weight/fat loss has very little to do with training and nutrition knowledge, and mostly to do with learning how to break bad habits and establish good habits. It's a psychological war more than a physiological war. However, that dichotomy is unnecessary, if inaccurate, since they're so intertwined.
