Intermittent Fasting: Lose Weight + Feel Great…Just Wait!

Dr. Edelman has been practicing intermittent fasting since the beginning of 2022. Not only are his blood sugars better, but he’s also looking svelte! His UCSD colleague, Dr. Preethika Ekanayake, also practices intermittent fasting, and they share the benefits that can be especially helpful for people with diabetes.

Intermittent Fasting: A Physician’s Perspective

  1. How long do you have to do intermittent fasting, say 16:8, before you would empty all your stores of glucose? Trying to see if I can reset the insulin resistance. I’m not overweight so only want to do to lower blood sugar. I do find evening exercise does help lower fasting but not to below 112. I’m doing low carb diet, actually have lost 50 lbs in a year but hasnt helped with that blood sugar thing.

    • To answer your initial question, it depends on your degree of exercise, because exercise will deplete your glucose and break down your glycogen. So at least 10-12 hours, but it could be faster if there’s exercise involved burning up your glucose.

      If you’ve lost 50 lbs and you’re not overweight and your fasting blood sugar gets down to 112, it may be the best you can do. If your fasting blood sugars begin to creep up over time, which they might, not in relation to anything you’ve done wrong, just the nature of the progression of the condition, you may need therapy…insulin or another medication.

      • Well my fasting actually have come down… 117 in April, 112 on labs in August. Some mornings they are in the upper 90’s? I don’t get it.

  2. Great video! Good information. More people, diabetic and non-diabetic, need to follow you.

    • Thanks Sandie – appreciate it!

    • Hi Sandie. I’m Sandie J Murray Taylor and have been Type 1 since May 28, 1972, 49 years. I have been on Omnipod since 2006, Dexcom since 2011and now on Omniopd 5/Dexcom 6.
      Welcome to “the club”.

  3. Your videos an content are great! Would you ever consider covering pregnancy and insulin resitence in the third trimester?

  4. I would have liked to see your Dietitian weigh in on this topic

  5. I’m type 1 and would like to try intermittent fasting. I think it would help control my BG for part of the day. The only problem is that I get so hungry and binge on low carb high fat foods whenever I try to skip a meal. Do you get crazy hungry during fasting?

    • For me personally, I’ve gotten used to fasting until my first meal at lunchtime, but sometimes I do get hungry and I’ll snack on something like nuts, or something low in calories. I’m not going to kill myself over sticking to the exact time frame, but if I do get a little hungry, I’ve probably fasted 10 hours or so by that point which is pretty good. Remember, there aren’t any set rules – it’s whatever works for YOU.

  6. Is it ok to exercise while fasting? I’m a morning brisk-walker and have always “needed” breakfast first, even before I became type 1 (LADA, dx @age 58 in 2016).
