4. Intermittent fasting
In general, intermittent fasting is a useful tool for lowering blood pressure. This simply means abstaining from food for a set amount of time. There are many different protocols with some people not eating for entire days and others going for much shorter periods of sans food. Either way, intermittent fasting once again gives the body to burn through all available blood sugar and eventually to move on to other sources.
This might also give you better long term benefits by increasing your metabolism and boosting your insulin sensitivity.
Intermittent fasting is a very good choice for those worried about high blood sugar levels but there is a lot of debate regarding its benefits and drawbacks. Do your own research, draw your own conclusions.
