"Bananas and Dates make me sleepy" Michael Arnstein
"I can easily eat 45 bananas a day" Durian Rider
Why the vast difference? Based on the above statements there is obviously somewhat of a difference - is it because we all have a different tolerance to the GI (Glycemic Index) or GL (Glycemic Load) levels in food?
I did an experiment on myself -
Fixed - 3 liters of water daily, exercise fairly the same each week, 10 hours of sleep min.
- One week all bananas and dates (3000cal not including salad) huge salad for dinner
- One week all high water content fruit (3000cal not including salad) huge salad for dinner
- One week with steel cut oats/brown rice/potatoes/lentils/split pea etc (3000cal not including salad) huge salad for dinner.
After most meals I would take blood and calculate blood sugar via a meter....I would also rate my nap needs 15 minutes post meal (1 = ready to roll - 5 = Bed needed now). Some meals would make me tired others would not. My blood sugar levels were always perfect; however, I could not keep my eyes open after certain meals.
I then eliminated every food that made me tired (they happen to be all of the higher GI foods) then presto = feeling great! For me I need lower gi foods (NOT lower carb) lower GI - huge huge huge difference.
Is it possible we all have different Insulin reactions to different foods? For me bananas or a huge batch of grapes would leave me so so tired. A blood glucose reader told me I was perfect - it "lied" - I needed an immediate bed. Lower GI foods left me feeling great.
These our just my observations - what are yours?
NOTE: High vs Low GI - most fruits and veggies are considered low GI compared to typical SAD diets. However, there is still a huge variance between many fruits and veggies.
I sometimes feel tired after eating, I think it depends on how much I eat at one meal though. The bigger meals are generally the ones that tire me out, I just put it down to needing more energy to digest it. I never actually need a nap though, I just feel a little tired for about half an hour to an hour.
What I do get with bananas a lot though is my mouth feels coated & dryer than it does normally. Even when I have them in a smoothie usually with at least a litre of water in the smoothie I still feel like my mouth is dehydrated & my tongue feels coated.
Does anybody have data about the difference of fruits in GI and II (InsulineIndex) if that's what it's called in english.
Yeah - Doug covers all these topics. I have a great deal of respect for Doug. I question everything I read - not just Doug's work. That way if I prove it for myself I have a greater understanding from the actual experience. I agree with much of 80/10/10 - I question not enough discussed about insulin resistance, amylase & brain size different between Bonobos and Humans.
Which fruits and veggies are lowwer GI, and which are higher GI?
Just Google GI fruits and veggies - but I feel your personal observations out way the charts.
I agree Harrison. Bananas and dates are a calorie choice when I can not get sweet watermelon or sweet mangoes.
Is GL really valid. From what I have read about it... it relates to 1 serving.
ie: Watermelon is low GL... if you eat a cup.... but what about 10 lbs ????
Bananas get me a bit... much less if they are fully ripe... and blended into a green smoothie.
This is uber interesting. What are the odds you'd be willing to share your full data/tables on how the whole 3 weeks went?
most of it on notebooks and spreadsheets - but I will try and organize it - it would be fun to share.
I would totally appreciate it :)
I did not noticed that I would be become fatigued after eating bananas or dates, however, sometimes my fingers get cold, expecially if weather is not warm (I dont use heating). It comes back to normal after about 1 hr.
AD, what was your blood sugar reading after different meal e.g dates, bananas, vs orange or oats.
