Do we need breakfast?

[AmberLeaf]

Coffee, biscuit and read my horoscope, and i'm off!

[Margarita Ma]

I think I'm getting worse, diabetes is the thing that I worry about.

 

Perhaps you should have a blood test to see if you are diabetic or pre diabetic.

the best version of that much regurgitated 'quote', which has become a bit of an urban myth, is this one :

 

Q. what is an expert?

 

A. an 'ex' is something in the past, and a 'spert' is a spray, that never made it.

 

that is one of those anonymous quotes, that has become a bit of an urban legend. Nobody knows, but it probably originated in some newsroom somewhere.

 

one things for sure though. Though nobody knows who they were, whoever's tongue that rolled off for the first time, was probably a hell of a lot wittier and smarter than you.

 

Very probably :hihi:

You have around 1500 - 2000 cal stored.

That's a days worth. Not just 90 minutes.

 

Its not going to last you a day when you are exercising thats the whole point. You then burn it off as fuel and when its depleted thats when you become exhausted. thats why you need carbohydrates to stave this off. I should have put 90-120.

 

It calculates 100g and at a burn of 1g per minute (assuming you are topped up) then thats 1h40 mins.

Since there hasn't been any evidence posted, I have done a little research.

Dietary guidelines recommend eating breakfast (in general). Why?

 

In 26-36 yo Australian adults, those who did not eat breakfast had a higher weight gain over 5 years.

https://www.ncbi.nlm.nih.gov/pubmed/28068968

 

Studies including those from the UK show that short term cognitive performance is enhanced by breakfast eating compared to no breakfast and also that eating foods with lower GI is better than sugary breakfasts.

There is also a link between not eating breakfast, a poor diet, obesity and increased cardiovascular risk.

Eating breakfast, as part of a calorie controlled diet aids weight loss

https://www.ncbi.nlm.nih.gov/pubmed/28110468

 

But simply requiring people who don't eat breakfast to start doing so contributes to weight gain in the short term (as these people tend to just add breakfast to their already high calorie diets)

if you where riding a mountain bike in the peaks, up the steepest of hills you could burn 500c per hour

 

you should have put 4 hours if you where a world class althete in training.

for the rest if us. its a while day.

 

Your saying 500 cals an hour is full out exercise?

My calorie estimate from various apps says I can burn 1000 calories an hour during intensive exercise. About 600/hour for normal exercise (actually cycling in the peaks)

My 10 km run is around 900 calories, according to sports tracker app

The whole point I suggested you run out of glycogen when you are doing moderate intensity exercise after about 90minutes and its wrth fueling up. When you do run out then you crash badly. Most people dont exercise that long, but its not uncommon.

 

The articles I read suggested it was liver glycogen that was important as that regulates blood sugar levels. I should have put 90-120m (the article I linked suggested 100g at a depeltion rate of 1gm per minute= 100m), but you can hold different amounts of Glycogen and im not sure you dont feel the effects long before due to depletion rather than having to use all the Glycogen you have.

 

I'm now informed above that we have enough for 4hrs moderate to intensive exercise as even elite athletes burn only 500 calories an hour and for the rest of us its all day (which ignores the fact of exercise. There is also the issue of glycogen recovery if you intend to exercise on a regular basis. This is why people eat carbs before and after, but I guess i was imagining it.

 

MY view is I perform better if ive had some carbs and will exercise for over 90 mins. If I go fasted then either when it gets to 90 mins plus you start to slow down considerably and if you go too hard then it takes much more time to recover. the best way to recover the depeltion is to eat carbs/ protein 2:1 on your recovery nutrition.

Do you do it fasted? Do you ever run out of energy if you do?

[biotechpete]

I regularly train after having been fasted of carbohydrate for days, and certainly notice a period of adaptation but I got to work without breakfast (I ate when I got there) and having had no carbs for 3 days setting some personal records on Strava this morning.

 

I find after no carb training, then I get even faster on carbs, that's partly why I do it, but to a certain extent I think metabolism can adapt to provide energy when you are used to not having carbs.

[jensen1378]

I find this an interesting topic.

I can't eat for about 2 hours after I get up. I have no appetite and cannot stomach food. Does anyone else feel like this when they first get up?

 

Yes. I never eat breakfast, usually i dont get uo in time but if i do i just cant stomach it and i wait for lunch.

 

Im also fit as a fiddle! You dont need breakfast, its just more calories haha
