I would like suggestions on what to order (Black) for my first subscription where I plan to have 2 meals a day Huel. I am small female, in very good shape though at age 60 have noticed some decrease in food/calories I need daily. Not a big deal but some impact, I am not looking to lose overall weight however would like to lose a bit of fat,lower “bad” cholesteral that is genetically inclination. Moderately active, very low pulse rate. I’d love suggestions on how much to consume each day to substitute 2 meals.
thanks in advance
