iirc there was at least one study that showed that people don’t crave to eat what nutrients they are missing (I am guessing apart from drinking when you are dehydrated but that’s not really a nutrient)
Weight loss studies provide additional arguments against the “nutrient deficiency” theory.
In one weight loss study, participants following a low-carb diet for two years reported much lower cravings for carb-rich foods than those following a low-fat diet.
Similarly, participants put on low-fat diets during the same period reported fewer cravings for high-fat foods (18).
In another study, very low-calorie liquid diets decreased the frequency of cravings overall (19).
If cravings were truly caused by a low intake of certain nutrients, the opposite effect would be expected.
