Let us call him Antonio.  He came to see me in the fall of 2019 accompanied by his daughter.  Even though he migrated here many years ago he continues to speak with a delightful Italian accent.  He explained that all his life he has been healthy, working hard and eating “good food, nothing from a box”.  He was upset that now at the age of 79, he had suddenly become diabetic.  He was unhappy to be on medication for his diabetes and his cholesterol.  His goal in coming to me was to improve his health and get off all medication.

I asked for copies of his labs before he started his medication and ordered some new blood tests to get more updated information.

Blood work

The blood work that resulted in Antionio’s doctor insisting on medication for his cholesterol and blood sugar, was not good.

Total cholesterol 260

Hdl cholesterol 39

Ldl cholesterol 210

Triglycerides 190

Fasting blood sugar 130

HA1c 6.7

I explained in our second visit that I thought he could obtain his goal, but it would require some changes in his eating habits.  I explained about Intermittent Fasting and the true benefits that could be obtained from it.

I also recommended some supplements to assist with blood sugar control and to support his heart health.  He started on Fish oil, Chromium and Vitamin D3 .

I explained that with this diet change he needed to make sure he religiously checked his morning blood sugar.  And that his first meal of the day should be low carbs. I suggested a Frittata (baked omelet with lots of veggies).  The other meals suggestions were for lunch salads with protein and for dinner protein (fish, chicken, grass fed beef) and veggies.   Our goal was to start to get the body with a limited carb diet, drop his insulin and help his blood sugar.

A two week follow up found Antonio right on task with his diet and supplements he even increased his walking to 20 min every day.  He was supper motivated.  He did not need any hand holding.  I gave him a lab slip to check everything but not for until he was doing this daily for 3 months.  We would review them and see where to go from there.

In 3 months’, time Antonio lost over 20 lbs. and felt great, his labs showed amazing change blood sugars and cholesterol were well within normal range.  I instructed him now to talk to his primary doctor and request to come off the medication so we could see if his routine would be enough to support these changes.

And indeed, off the medication, we found that these changes were sufficient to keep him right where he needed to be.  He is proud to have accomplished his goal.  And I was proud of him as well.
