25 year shelf life . enough reason for me . <| sep |> Thanks for the tip , I ' ll try it out . <| sep |> Well yes , if you ' ve got underlying medical issues that ' s going to limit what you can eat , but that ' s a situation the vast majority of people aren ' t in . And yes , you ' re right , in some ways . All diets work as expected If you ' re physiologically healthy that is but some people have an easier time following certain diets . I do believe you should stick your diets for a time though , since most people will jump between diets without getting any long term benefits . Dieting sucks and nothing will stop that , and that ' s something people need to understand . For a lot of people The majority eating highfat won ' t keep them satisfied much longer . The only macronutrient that has a provable advantage is protein .
