There is a general sense of earlier is better: > Research is starting to show the same effects in humans. One study on weight loss that compared the times of eating among participants over a 20-week period revealed that those who ate lunch earlier lost more weight than those who ate it later. A related study found that those who ate later burned less energy than those who ate earlier.

If the study doesn't take chronotype into consideration, what does "early" even mean? Humans have a natural variation in our circadian rhythms, and 90% or so lie within a 4h window. So you might eat before I wake up, or my breakfast might be your lunch.

The article seems to be doing that most common journalistic trope: misinterpreting data and selling you a false narrative. Most of it is about when you gain more weight , not what is more or less healthy (it's not like you're getting sick). On the other hand, animals are normally the most insulin resistant during their typical sleeping hours. Studies suggest the same phenomena occur in humans. It turns out that mealt…

Decreasing weight gain heavily correlates to staying healthy. It's a reasonable enough proxy that people start to use it interchangably.

We have plenty of studies about this from body building. What you eat is orders of magnitude more important than when you eat. So while you can measure effects of timing and they are real, they are insignificant to most but the top competition level where 1% can make a difference.

Those studies give a good idea of the effects on body builders. You can't just automagically extend that to the general population.

The authors take aim at your daily - or circadian - rhythm. This is difficult because the circadian cycle is superimposed on natures annual cycle.

If your goal is weight loss, you should concentrate on the time of year - not the time of day.

The 3 months between the fall equinox and the winter solstice (Oct - Dec) are the most difficult for dieters. Not because of the holidays, but because nature is preparing you to hibernate.

The best period to start dieting is between the winter solstice and the spring equinox (Jan - Mar). Each day tends to become easier to control your eating.

The period between the spring and fall equinoxes (Apr - Sep) are usually the easiest to maintain healthy eating habits.

Yes, there can be exceptions, but if you chart your daily weight, you will see the pattern.

The good news is that NOW (Jan) is the best time of the year to start a diet. Don't put it off because at this time of the year nature will conspire to assist you.

I've never heard that caffeine prevents the clearing of adenosine receptors, a quick google didn't show anything with that side affect, do you have a particular citation? I'd definitely change coffee consumption habits if that is the case.

Personally, I learned this from Dr. Andrew Huberman… https://podclips.com/c/why-andrew-huberman-avoids-caffeine-f... https://www.reddit.com/r/AdvancedFitness/comments/qaq6z4/dr_... Sources should be in the show notes of the corresponding podcast episodes. Anecdotally: I can tell the difference.

Podcasts and Reddit is the same as no source at all.

If it's not a peer-reviewed published research (actually, multiple) it's not credible.

It doesn't mean it's wrong, but presenting it as a fact like the OP did is wrong and potentially extremely harmful.

You'll find a lot of references if you use a search engine to search for “caffeine and adenosine”. Here's the first result from my search: https://pubmed.ncbi.nlm.nih.gov/20164566/

That cite doesn't support what the person said above. Here is their claim again:

> So if you drink caffeine in the first ~90minutes of waking then you dont actually clear the adenosine as well, and then when the caffeine hits it's half life (about 6 hours later) you'll feel tired again. Solution: let your body clear adenosine naturally before you consume caffeine.

That is a very specific claim. Your cite is about caffeine antagonizing adenosine receptors, but what the comment above is talking about is that caffeine slows your body from clearing adenosine in your blood which is very different.

I'd like to read a cite about the above quoted claim. Simplying googling "adenosine and caffeine" doesn't immediately support it, because again "antagonizing adenosine receptors" and "dont actually clear the adenosine as well" aren't remotely the same claim.

Nah, c'mon, Most of us are unqualified to synthesize the dozens (if not hundreds) of sources it takes to be an expert in a field. Saying podcasts and reddit is the same as no source is like saying "People are no source" -- it entirely depends on the person.

That's a decently trustworthy source to trust for physiological information.

I mean, do you force your GP to provide sources and then go read them before you take their advice? Even if you do, it's not advisable for the majority of people.

Pretty junky article, because it doesn't define the goal, and therefore cannot give any recommendations either. Is the goal weight loss? Is the goal sleep quality? Is the goal how to maximize muscle protein synthesis (and add weight)? When it comes to weight loss (and when the right muscle sparing tools are in place, also fat loss) total Calories in vs Calories out dominates. Don't get fooled, both sides of the equat…

Time restricted feeding is a form of natural calorie restriction and it's the caloric restriction that causes the change in the body.

When equated for calories, protein, and fiber (and their "Calories Out" side effects) there is no statistically significant difference in diets from the twinkie diet[1], keto, low carb, low fat (though not too too low cause of hormones), one meal a day, 12/12 or 16/8 or 5d/2d intermittent fasting...
