Claim 15
Independent Claim
46 words
A method of treating obesity comprising administering to a person suffering therefrom an effective amount of (a) γ-linolenic acid or physiologically functional derivative thereof and/or dihomo-γ-linolenic acid or a physiologically functional derivative thereof and conjoint amounts of (b) physiologically assimilable zinc, and (c) a β-lactam antibiotic.
Claim 16
Independent Claim
46 words
A method of treating obesity comprising administering to a person suffering therefrom an effective amount of (a) γ-linolenic acid or physiologically functional derivative thereof and/or dihomo-γ-linolenic acid or a physiologically functional derivative thereof and conjoint amounts of (b) physiologically assimilable zinc, and (c) a β-lactam antibiotic.
