I have cut fat to 15 grams a day and calories to 1700. I exercise 4 times a week for 30 min. I have been doing this for a year. Often a high triglyceride level like yours points toward undiagnosed diabetes. Triglycerides are effected by sugar and alcohol , not the fat content in your diet.
Exercise can bring down blood sugar levels.
Both your HDL and LDL are within normal ranges. Until your triglycerides come down below normal, you should avoid all alcohol , sugar and concentrated sweets including your daily mocha. If you are exercising 3 to 5 times per week for at least 30 minutes, then you may want to talk to an exercise physiologist to tailor an exercise program for you. I'm in the process of applying for life insurance. I just received the blood test results back and there are 3 elevated items.
