Thanks for your query to HCmagic.
The target LDL cholesterol
for you can not be calculated in the absence of certain details like history of high blood pressure/ diabetes/ family history of premature anginal heart disease/ smoking/ history of existing cardio-vascular disease
It is good That you have started life style modifications. If you do not have any of the above risk factors, then probably you require only lifestyle modifications for now and repeat lipid profile
after 3 months. Else provide us the details so that exact management can be discussed. Since your triglycerides are high, i would like you to stop taking alcohol and cut on your carbohydrates intake too.
Feel free to discuss further.
