What causes cholesterol to jump? I've left a lot to be desired in sticking to the plan for the last few months, I haven't done really well :( That said I tried sticking to better habits. My cholesterol was high at my last blood test but it really got on the trampoline for this blood test. Any thoughts why? Would it have anything to do with the food? My foot has been acting up too so I haven't been active at all.
