I just read an article about a research at U of Alabama,
it says two groups of rats were fed either carbs or fat for breakfast.
Carb group tended to burn only carb through out the day,
Fat group tended to burn both carb and fat during the day.
They plan to test it on human subjects.
I faintly remember my friend telling me that he had read something like this, eat fat for breakfast, etc…
any thoughts?
If it is the same for humans, would eating fatty(healthy fat) breakfast on low carb days of cycling be beneficial?
Man these mouse studies are getting a bit out of hand. Try not to extrapolate to much on these studies, a lot of the time it doesn’t carry over to humans and many of these are in their infancy. This means that things may react much different in humans.
Now onto this topic, when on a low carb diet aren’t you already doing this? I mean is it that surprising? We already no the effects of cutting carbs and increasing fat. It seems to me all they have to done is replicated a lower carb diet in mice…WOW.

If I recall correctly, you need a certain amount of ‘carbs’ (glycogen) to burn fat efficiently, so the results tie in with human physiology to a degree.
My high fat breakfast is either bacon and eggs, or a bacon omlette with shredded chicken and veg.

How would you best address this need for carbs? Refeeds? Just how much are we talking?

None. The human body functions perfectly fine in the absence of carbohydrates, some would argue more efficiently, as long as fat is utilized as a primary source of energy (which it would be in such a case).
It automatically sounds fishy. First, it’s in rats, not people. Second, if they only burned carbs ALL day, they may have been getting an extreme amount of carbs or something. Like 110% of their daily burn.
Balanced diets and maintenance calories generally mean you spend some time getting more energy from carbs, and some time getting more energy from fat. Carb intake just shifts the percentages.
Well then I don’t think they would be physiologists, since it has been shown that to achieve most efficient fat burning, you need to burn some glucose too.
You’ll get no argument from me that a body can utilise only fat and protein for energy. However I still stand by my assertion that to burn fat most efficiently, some trace glucose is needed.

where has this been shown? is there some evidence to look at?
I was taught (read: I am partway into a sports nutrition class) that fat burns in a carbohydrate flame, so to speak…when you don’t eat enough carbs, there isn’t enough oxaloacetate (due to low pyruvate) produced to deal with all of the acetyl CoA produced via beta oxidation (which is fatty acid oxidation) and continue the Kreb’s cycle, so the acetyl CoA become ketone bodies…ketosis, voila.
A carb-cycling diet isn’t going to put you into ketosis, nor is choosing to eat a high-fat, protein meal for breakfast the day after a medium or high carb day. So there’s obviously a difference in the discussion between someone on a long-term low-carb diet versus what the OP is doing.
I don’t even know what the argument is here - if it’s a low carb day in your cycle, what else would you be eating for breakfast (as others have pointed out)?
After I wrote all of that…I have no idea who or what I am responding to…what else were the rats eating? Were they on a carb-cycling diet? The applicability to what the OP is doing seems minimal, if there is any.
hypothetically, would gluconogenic amino acids from proteins provide enough glucose for the efficient usage of fat BBB? doesn’t really affect me since i eat carbs, but just curious.
