THREE IMPORTANT STRATEGIES TO ACHIEVE PERFECT BLOOD GLUCOSE LEVELS AFTER EATING


THREE KEY WAYS TO ACHIEVE PERFECT BLOOD GLUCOSE LEVELS AFTER EATING

How do you know if your mealtime insulin dosing method is accurate?

  • Do you sometimes go high after eating?
  • Do you sometimes go low?
  • Do you have both highs and lows from day to day?

 

Frustrated by it all? ThIS article discusses how you can test the accuracy of your mealtime insulin dosing method, identify inaccuracies and put a solution in place, if needs be.

 

Please remember, it’s your responsibility to discuss any changes to your insulin regimen with your medical team. This is for information purposes only.

 

In order to test the accuracy of your mealtime insulin doses we need to breakdown the assessment into three simple steps:

  1. Preparing for the test.
  2. Completing the test.
  3. Reviewing your results and making valid changes.

 


 

Before we get started, you must consider what type of diet you currently follow.

 

Are you following a…

  • Low carb approach?
  • Zone style approach?
  • KETO approach?
  • High carb approach?

Or,

  • Are you doing what most people do, chopping and changing from meal to meal and day to day?

 

This last question is the most important one you can ever ask because:

 

If you are chopping and changing your macronutrient intake (carbs, fats, and protein) from meal to meal and day to day, you will NEVER get consistent results from your mealtime insulin doses.

 

Does this sound like you?

 

If so, you have two options:

 

1. Carry on as you are, stop reading this article, and expect the same results you’ve always had – Blood glucose levels all over the place after meals.

Or,

2. Be more consistent with your macronutrient intake. It does not matter if it’s low carb, high carb, KETO, Zone etc. – Consistency is what matters.

 

If you have chosen option two, or if you are already following a consistent macronutrient intake, this three-step methodology will work for you.

 

For accuracy – you will need to repeat the test twice at each meal time to ensure what you see is not an anomaly. Therefore, you need to identify two rest days or two training days.

And yes, you would be right in thinking the day where you do 60-minutes HIIT  may require a different post-exercise meal insulin vs. a 45-minute strength session at medium intensity.

But, for now, let’s keep things simple and look at exercise days and rest days. You will need two of each.

 


STEP 1: PREPARING FOR THE TEST


 

In order to make the test fair, you must meet the following conditions before testing your blood glucose level before the mealtime you are testing.

1. Consume your last meal and give your last insulin dose at least 4 hours before.

2. Your last meal should have no more than 30g fat – otherwise, you run the risk of delayed hyperglycaemia.

3. No correction insulin in the four hours before.

4. No snacks within four hours.

What if I go Hypo during the test?

If you go hypo you will need to eat and re-do the test another day.

 


STEP 2: DURING THE TEST


Calculate your insulin dose using your usual method. Usually, this is carbohydrate counting and applying an insulin to carbohydrate ratio, although you may also count protein and use a similar ratio. A popular method is to count 50% of protein applying the same insulin to carbohydrate ratio. Be sure to weigh your food to get an accurate count.

 

Do not include a correction dose of insulin, you only want to be testing the insulin for the meal.

 

Give the insulin 15 minutes before eating.

 

Maintain normal activities – No sex, masturbation, running, etc…

Test your glucose at the following points:

  • Just before eating,
  • Two hours after eating,
  • Four hours after eating.

If you have CGM this is golden, you will get the full picture.

Again, you need at least two tests of the mealtime before considering making a change.

 

TWO OF THE SAME DAYS – Two rest days, or two exercise days – DO NOT MIX THESE UP!

 

 


STEP 3: DURING THE TEST


 

You must speak to your medical team before implementing any of this.

WHAT TO DO IF BLOOD GLUCOSE INCREASES DURING THE TEST.

 

If your blood glucose level goes up by more than 2 mmol/l (36mg/dl) from before the test to four hours after – on both occasions:

Consider adjusting the insulin to carbohydrate ratio to give 10-20% more insulin. How you do this depends on which side of the ratio you change. If you change the carbohydrate side of the ratio, then reduce the carbohydrate by 10-20%.

 

For example, if your current ratio is 1 Unit : 10g carbs, change to 1 Unit : 9g carbs (10%) or 1 Unit : 8g carbs (20%)

But if you change the insulin side of the ratio, then increase by 10-20%.

 

For example, if 1.0 Unit : 10g carbs, change to 1.1 Unit : 10g carbs (10%) or 1.2 Unit : 10g carbs (20%).

 

If your blood glucose level goes up by more than 2 mmol/l (36mg/dl) from before the test to two hours, but is back within 2 mmol/l (35mg/dl) after four hours – on both occasions:

Consider delivering the insulin earlier than 15 minutes before eating. You could even try 30 minutes before.

 

 

WHAT TO DO IF BLOOD GLUCOSE DECREASES DURING THE TEST.

 

If your blood glucose level drops by more than 2 mmol/l (36mg/dl) from before the test to two hours after – on both occasions:

Consider adjusting the insulin to carbohydrate ratio to give 20% less insulin. How you do this depends on which side of the ratio you change. If you change the carbohydrate side of the ratio, then increase the carbohydrate by 20%.

 

For example,

If 1 Unit : 10g carbs, change to 1 Unit : 12g carbs (20%).

 

But if you change the insulin side of the ratio, then reduce by 20%.

For example,

If 1.0 Unit : 10g carbs, change to 0.8 Units : 10g carbs (20%).

 

If your blood glucose level lowers by more than 2mmol/l (36mg/dl) from before the test to four hours after – on both occasions:

Consider adjusting the insulin to carbohydrate ratio to give 10% less insulin. How you do this depends on which side of the ratio you change.

 

If you change the carbohydrate side of the ratio, then increase the carbohydrate by 10%.

 

For example,

If 1 Unit:10g carbs, change to 1 Unit : 11g carbs(10%).

 

But if you change the insulin side of the ratio, then reduce by 10%.

 

For example,

if 1 Unit:10g carbs, change to 0.9 Units : 10g carbs (10%).

 

Obviously, you may need different mealtime insulin dosing method for exercise and non-exercise days.

You may even have different methods for HIIT vs. Strength days – depending on your level of need, and OCD (like me).


Round Up: Five Key Tips That Help Ensure Consistent After-meal Blood Glucose Readings.


 

1. Keep your macronutrient meal amounts consistent from meal to meal and day to day.

 

2. Respect the fact that your mealtime insulin dosing method will be different on rest days and workout days.

 

3. If your meal contains over 30g fat and at least 30g carbs, there is a risk of delayed high glucose levels. For this, you will need extra insulin and to split the insulin dose.

 

4. Try to deliver mealtime insulin 15 minutes before eating, if not earlier.

 

5. Occasionally weigh your food to make sure your carbohydrate (and maybe protein) counting is accurate.
