Does intermittent fasting help with uncontrolled blood sugar levels? Is vomiting during a fast okay? What could feeling cold when fasting mean? And, what can one do when nothing is working for weight loss?
It's time for this week's Q&A about intermittent fasting and low carb with Dr. Jason Fung:
HIGH blood sugars while fasting and LCHF diet
- Is it possible that intermittent fasting is not good for some diabetics with uncontrolled blood sugars?
- Is it more important to get on a new medication to control these high numbers than it is to "wait it out" with diet and IF alone?
Tanya
- Intermittent fasting usually lowers blood sugars, but the effect is variable. In some cases, it goes down quickly, and others very slowly.
- Questions regarding medications can only be addressed by your own physician.

Nausea and vomiting
Is vomiting during a prolonged fasting period normal?Asha
No, vomiting is not normal during fasting. You can be hungry, but should not be vomiting. You should stop and seek medical advice.

Core body temperature dropping during a fast
Should otherwise healthy people generally stop a 'fast' if they notice this coldness occurring and/ or can track a small body temperature change of up to .2 degrees below their normal temperature range during fasting?Penelope
Feeling cold is a sign of lowered basal metabolism. It would be important to revisit your dietary regimen to see if anything can be optimized. That may include stopping the fasting.

Tests and best way to start
Do you have any recommendations for losing weight if keto and other diets don't work? As to how to start and what tests that could be run, and continue to run, as well as target test results?Kelley
Try intermittent or extended fasting. Blood tests would be at the discretion of your own physician.
