High quantities of (bad) fat in your meal plan has a huge impact on your diabetes management.

There are two things to keep in mind when we talk about fat and diabetes management:

  1. The fat consumption in the meals impact the blood glucose levels
  2. Insulin resistance is also caused by the regular consumption of fat

What about the liver and his role in diabetes management?

  • The liver is essential in so many body processes:
    • produces proteins that are important in blood clotting;
    • kills old or damaged blood cells;
    • plays a central role in all metabolic processes;
    • you name it…
  • The liver plays an extremely important role with glucose release;
  • In the presence of diabetes the liver is already highly affected;
  • 80% of people with diabetes have a fatty liver.

Here are 5 reasons to reduce bad fats content in your meal plan…

…and focus on a balanced diet instead.

1 High Fat content in the meals delays the absorption of the carbohydrates that are consumed with it.

This delay happens due to fat – and particularly saturated fats – slowing the digestion. A slow digestion means an unexpected and very delayed blood glucose rise.

2 In the presence of fat, body cells become more resistant to insulin

In fact, the presence of fat in the bloodstream, from the food we eat can build up inside the body’s cell, and develops a  toxic fatty breakdown products and free radicals that can block the insulin action to allow the glucose to go inside the cell.  So no matter how much insulin we have out in our blood, it’s not able to open the glucose gates, and blood sugar levels build up in the blood.

3 The liver loses the sensitivity to insulin when in presence of high quantities of fat in the meals.

In normal conditions, the insulin sends two different signals to the liver. One signal will inform the liver to keep the stored glucose it keeps because there is enough glucose already circulating in the blood stream, the other signal tells the liver to deliver glucose in the blood stream. What happens in the case of the presence of fat in the cells, which also causes insulin resistance, is that these signals are not being transmited clearly and the liver ends up delivering more glucose to the blood stream.

 If in the previous reason you get a delayed glucose rise, now you get a secondary blood glucose rise done by the liver.

4 Fat increases insulin resistance

In fact, studies (1,2) show that a “hit of fat can start causing insulin resistance, inhibiting glucose uptake after just 160 minutes”. This means that the reduction of fat from the diet will reduce insulin resistance and as a consequence will have positive impact on the blood glucose levels.

5 High content of bad fats/cholesterol in a diet have impact on your cholesterol levels.

Diabetes alone is already a risk factor to develop strokes and heart conditions so make sure you choose more frequently unsaturated fats to be part of your diet. 


Need any other excuse to keep high content fat in your diet? Or is it time to start reducing it? Challenge yourself – small changes are always the best way to Change!
