It is for about 20 hours. I usually eat dinner and skip breakfast and lunch. I will have a snack on the way home with my son, it is usually an apple and dried seeds and fruits. The research has shown up to about 300 calories provides the same benefit.

I also cannot fathom paying for lunch everyday, or coffee. I get lunch once a month from a cafe down the street and maybe every six weeks I will get a bagel egg-which for breakfast. I buy a coffee maybe once every two months. McDonalds has my favorite store chain coffee and they have stickers to get a free coffee (7 then a free medium). I just stop along my commute and collect stickers. I think I have three or four free coffee coupons in my wallet right now. I will stop to get the stickers but too lazy to stop and get the coffee.


I like all the savings since it makes it easy to justify the weekly growler fill and whenever I want something new for myself (read my bike)
