If healthy, protein: If you are feeling well, and ideally have been evaluated by a physician recently to be sure you do not have a metabolic condition (such as thyroid disease or diabetes) and are not taking stimulant medications, then adding a protein supplement to your regular diet--without reducing your usual intake--can help. This can be as a snack bar, meal-replacement bar, or powder you add to drinks. ...Read more

Hi LDL: Hi. Your BP is excellent. Your LDL is high and your HDL is not great. Your triglycerides and calculated VLDL are great (and suggestive of good insulin sensitivity). You're young, and it's hard to recommend lifelong preventive medicine sometimes for some people (not for me or for many others, however). Glucose > 100 - was that fasting? If so, that's abnormal; if not, probably OK. I'd treat LDL. ...Read more
