Maybe a parasite cleanse might be more appropriate at this point. I know that my intense cravings for sweet went away with high doses of olive leaf extract (16% tincture) and with Paranil (Dr. Natura).

I would not do a Master-Cleanse while training for a marathon. Some exercise might be ok, but something that strenuous would defeat the purpose. Your body is supposed to detox and heal itself.

I'm about to embark on my second MC, my first was over 6 years ago so while it's been some time, I do have experience with it. I've also trained for and completed 2 full marathons, several half's and 10K's, and 3 Oly distance triathlons. Through those experiences, I'm very familiar with endurance training nutritional needs.

I can honestly say that Master-Cleanse or any fast for that matter will not be enough to support you while training for a marathon. Your body needs whole, nutrient dense foods to rebuild the muscles that you are tearing down through long distance running.

To take it one step further from my experience, I have also struggled with Sugar addiction/habits, over-eating, bingeing, you name it...I've done it. The Master-Cleanse didn't cure your Sugar habit before, you did. Through your determination. You can do it again if you work hard at it but be gentle with yourself too. Don't expect perfection. None of us are perfect!

Two books that really helped me with my eating habits and Sugar addiction are:
"Thin Tastes Better" by Steven Gullo, MD. (discusses behavior changes)
"Potatoes Not Prozac" by Kathleen DesMaisons, PhD., Addictive Nutrition (on sugar addition and the biochemical reaction that occurs in our brain/bodies when we ingest simple sugars.)

Hope that helps! Good luck on your marathon!

I just read that it can be healed by making sesame seed milk daily for a couple weeks while eating a raw diet. Perfect ofr marathon training.
The Master-Cleanse is not a diet for heavy athletic exertion.. it is a cleanse.
Best Always,
