Any Diabetic's Tried the 5 Day Pouch Test?

I am Diabetic, if i go for more than 4 hours without eating i get weak in my legs..I am wanting to try this plan for awhile, but not talked with anyone about it..Im always running places doing errands I need energy , dont have time to feel weak in my legs if all i am eating/ drinking is broth for a few days. I want to get started now before summer , I want to take off another 15 or 20 lbs before summer starts..I've been putting this off for a couple of years now. Is this doable without getting aggitated or risking my health more at this point? thanks Wendy
