Can you eat gum when fasting?

It is a tricky question, but yes you can eat or chew sugar-free gum when fasting. Sugar-free gum has minimum effects on insulin and contains very few calories. But, you need to be aware that some fasts are very strict and prohibit consuming any calories at all. 

What is intermittent fasting? 

It is a way to lose weight and manage weight control. It is an eating plan that switches between fasting and eating on a schedule. Intermittent fasting focuses on when to eat instead of what you eat.

For example, the most common is 16:8, you fast for 16 hours and eat in the next 8 hours. The recommendation is to have a healthy diet in those 8 hours and not eat just what you can. 

How does fasting work? 

The basic idea is that by restricting food, our body will burn more efficiently our fat storage. During times of deprivation, our main source of energy is fat. So, when you fast instead of using glucose from food for the energy you use your fat storage. 

What can I consume when fasting?

  • Water
  • Black Coffee
  • Sprinkled water, no calories
  • Sugar-free gum if necessary
  • Tea no sugar added 

Once you break the fast, the recommendation is to consume a healthy diet with all groups of food. You can follow the Mediterranean diet, and pick unrefined carbs like whole grains, leafy greens, healthy fats, and lean proteins.

Does eating or chewing gum break my fast?

It depends on how strict your fasting is. Sugar-free gum contains 6 calories while regular gum contains about 11 calories. 

For a strict fast, do not eat any gum. However, there is a rule that you can consume less than 50 calories and it will not affect you fast, so if you want to follow this rule I recommend that you go for the sugar-free gum.
