My recent cholesterol test was high. Total cholesterol was 257, HDL 78, LDL 148, Triglycerides 161. I have smoked 1 to 2 packs of cigarettes on the weekends for the last 10 years. I do not smoke Monday through Friday. My blood test was on a Monday. Could quitting smoking really lower my levels or do I really not smoke enough to make any difference at all if I quit. I am 130 pounds, 5'4". I do 40 min of cardio every day and 25 min strength training 5 days per week. I eat a healthy diet with lots of fruits and vegetables, some sugar, but NO fried foods.
