What you have described is what is known as Reactive hyperglycemia
. The body reacts excessively to your to your meal by releasing more insulin. This is often seen in prediabetics. What you should do is get your HbA1c tested. If this falls in the range of 5.7-6.5% you are a pre-diabetic. Nowadays Metformin is used even in prediabetics and it is helpful in preventing subsequent development of diabetes mellitus
You triglycerides are also pretty high. We can start you on fenofibrate
to reduce it however recent trials have not shown much benefit of fenofibrates alone. Fatty liver is part of metabolic syndrome
and prediabetes too is a part of the same syndrome.
Hope this helps
