tomorrow mornin im hittin the gym quite early so i cant eat my normal breakfast(im on a diet)but i do need a really light pre-wokout snack(even a diet juice or somethin)to fuel my workout without the risk of throwing up.Any Suggestions?

for the next 5 days... this is my menu:
Breakfast: 50cal unleavened bread, 1 grapefruit
Lunch: 50cal unleavened bread, 1 grapefruit
Snack: 50cal unleavened bread, <100 cal worth of fruit (ex: 2 kiwi)
Dinner: 50cal unleavened bread, 1 grapefruit
Total Calorie Intake: is about 650
I will exercise about 30 min/day (approximately 200-250 cal)

would it work? the fruits are on the negative calorie list. the carbs are just to fuel my brain

I have a huge problem with snacking....i eat so well during my main meals then I ruin it by snacking on just in between. I find that when I don't snack i'm either really hungry by the time I have a real meal, or i get grumpy really fast. I excersise and do alot of activities so i know i need to eat something to keep me fueled. is there any tricks that you used to help you stop snakcing bad, and can you recommend some good snacks i can have that wont ruin my diet? Thanks in advance!
