i've been looking into the 5:2 diet - basically eat 5 days normal and 2 days of 600 calories or fewer for 2 days (not consecutive). Meant to be very effective.
The reasoning is that as hunter gatherers we seldom had enough food all the time so were either feasting or fasting.
Theory is fasting sharpens our minds too as we wanted to be sharp when hunting for animals - makes me wonder about pre race meal and just how full you should be? Could fasting a bit be beneficial? Thoughts?
There are still hunter gatherers around and I doubt they fast 30 percent of the time. Just because they aren't farmers doesn't mean they can't preserve food. And because they aren't farmers, they're less likely to outstrip their food supply.
Famines and starvation happen in agricultural populations. There are so many people that any failure in the crops can be disastrous. I think that's why people of certain ancestry have a hard time not getting fat, it's like famine insurance to their genes. They should call that diet the "roman famine" diet. The crop in egypt was bad so food is rationed and off limits two days a week.
Sounds like horseshit to me. But hey, if I see some soundly designed scientific studies that prove that the lifestyle is advantageous, then I'll go with it.
Not a lot of science to back it up but a heap of anecdotal evidence

Hunter gatherers, if you believe that you can better follow the Paleo diet... Unbelievable that people believe these lies.
My guess is that people are actually restricting overall weekly calories without knowing it. They are not eating enough surplus calories on the non-fasting days to make up for the 600 calorie fasting days. So their weekly caloric intake is lower.
Probably a way to fool yourself into consuming less per week for people who couldn't handle a consistent DAILY cut in calories. Until some solid studies come out, it's all yappity yap horseshit to me.
have you read the links. sounds okay to me. and i have two friends who have used it successfully. the thing is to get a diet people can stick to.
i'm surprised no one on the board hasn't tried the 5:2 diet. I started today with a fast. and i found keeping to 600 grams for the day hard. it's meant to get easier.
the diet is more well known in england
so back to the original questions
makes me wonder about pre race meal and just how full you should be?

Because we don't have to "diet" here. We just run. If anything, we have difficulty stuffing ENOUGH calories down our gullets.
OK fair enough
Not everyone is able to still run
The main thing was about a pre race meal. The diet got me thinking about it
