Most studies connect intermittent fasting to stress reduction , and to improve cardiovascular health. A study published in Cell Metabolism demonstrates intermittent fasting decreases your oxidative stress and improves your insulin sensitivity. During your fast, your insulin levels decrease.
In response, your body releases hormones from your liver, one of which is the stress hormone, cortisol. Cortisol tells the liver to release more glucose. As a result, your blood sugar levels will increase. Exercise is a vital way to utilize sugar in your blood and help your body return to a fat-burning state. If you have diabetes, this can potentially be dangerous since diabetes medications already put you at risk for low blood sugar. These findings are significant since low blood sugar is vital to reduce your risk of cardiovascular disease and diabetes and for more excellent long-term health.

Your doctor only knows your history and can provide you with the perfect IF option, so it would be great if you ask them about the safest and the most efficient fasting protocol.
Is my body burning fat? Reply: 55 55 Reply to comment 54 by Sher Kristin Parker Team Diet Doctor October 19 I started fasting to lose weight and my glucose drops and stays between 3 and 5. Ok i understand when you explained to Mindy, as to why glucose level elevated during s long fast. It comes from Liver. I am the same way so my liver has a lot of glucose.
What happens now if I check my A1C? If my glucose level every morning is from , my A1C result will be higher than normal. Dear Doc Fung, I am 62 years old, I bought your books to cure my type two diabetes, your videos on you tube encourage me a lot, and I was doing fantastic for two weeks my readings were 85 to Max incredible results I was very happy, until today not sure what happened I woke up and i had a vertigo attack that lasted 5 minutes was horrible, everything was spinning out of control, and suddenly my blood sugar went to , and Thanks God I lowered down to 's and then to at four o'clock, not sure what happened?
Is that normal? I will continue with the plan because I want to get rid of diabetes, not sure what happened, never experimented this before, hope that things go well from now on, I still taking medication for it I am not sure how long it takes before I can get out of meds? I am serious on getting healthy again, what did I do wrong? Thank you Luis.
Please check in with your doctor. The vertigo or some sort of system stress on your body may have affected your blood sugar but you should see your doctor for thorough diagnosis and treatment.

Jason Fung. Fung All posts by Dr. Fung Dr. This triggers beta cells in the pancreas to release insulin in order to keep blood glucose levels in check. But if you have diabetes, you may not make enough insulin or may be too insulin resistant to counter the increase in blood sugar. As a result, your levels may be elevated when you wake up. The dawn phenomenon does not discriminate between types of diabetes. Approximately half of those with either type 1 or type 2 experience it.
If your insulin level falls too low overnight, your blood sugar rises. The reasons for the drop in insulin vary from person to person, but it most commonly occurs when your insulin pump settings provide too little basal background insulin overnight or if your long-acting insulin dose is too low.
Insulin duration—how long the drug works in your body—also comes into play. If you inject your long-acting insulin early, it may not last into the morning.
Say you miss dinner or take too much insulin after your evening meal. Your blood sugar may fall too low overnight. Your body makes more glucose in order to compensate, and you wake up with high blood sugar. If a pattern of frequent morning highs emerges during your routine glucose monitoring, check your blood sugar levels at bedtime, in the middle of the night and first thing when you wake up to develop a better understanding of your glucose patterns.
Your readings will tell you and your doctor when your highs and lows occur and that, in turn, will help narrow the cause of the problem. If you have high blood sugars before you go to sleep, the elevated level can persist until morning.
