                                Severely malnourished cancer patients have been observed to gain an average of 4.5 kg in two weeks on Total Parenteral Nutrition (TPN). The exact amount of weight a person can gain on TPN, however, varies widely depending on numerous individual factors, including their initial nutritional status, the specific TPN formula, and overall health condition.
