Hello Brooke

A few times a week I do Bikram Yoga. The class is from 6 to 730 pm.
Is it best to eat at 430 pm and fast all night and eat the next day around 0830 to make this a 16 hr fast or skip the 430 pm meal and eat at 8 pm and eat the next day around noon? Or does it matter?
I started my protocol recently and can not really tell at this point with regards to weight loss. I was not sure if eating close to bed mattered.
Thanks!
