Lions can't eat ducks or chickens. We can and do.
Why should I, as a top predator, drink a protein powder instead eating a meat of a big mammal?
Why did you drink them before, if you appear to fundamentally object to the idea?
Bears are a terrible example to pick, as they aren't real “predators” in the first place. They are omnivorous, eating more fruits, roots and insects than meat, by far. Depending on their species and where they live they may eat fishes as well, but not that much meat at all.
And of course as omnivorous ourselves, we eat far less meat than actual predators like wolves and felines.
As in they can't catch them? Or they can't survive on a diet of them? I'd be surprised if it was the latter.
As someone who lifted for a good handful of years, there are a few reasons i used protein powder, it was a very affordable way to add 25-50g of protein and some random fruits or peanut butter or whatever(i'd usually blend up a shake).
It was also a good way as someone who struggles to eat a surplus, to hit my goals as it just went down way easier than an additional full meal.
It is ALSO easier to cut weight and maintain protein goals by utilizing simply water and protein powder.
when it came time for me to cut, im simply swapping milk for water, and removing the peanut butter, and suddenly that "meal" is ~400 calories less.
So the very simple answer? convenience/affordability.
You must have always known humans were apex predators, and that was the only non-sweetener reason you listed.
I can't imagine anyone actually saying this with a straight face (also I am totally using this line for everything now). What a way to view oneself!
Fat's thermal food effect is 3% of fat's energy, while sugar and amino acids have 8 to 10 times more of their energy converted to heat (25% and 30%). That thermal effect raises the body temperature and makes body to sweat.
Ketogenic diet also allow for fat burn through the year, not at the cut stage only. I once managed to burn fat and bulk at the same time, burning 2 kg of fat and adding 4.5 kg of lean mass in three months, just by switching to intermittent fasting and hypertrophy-specific training. Without PEDs - they interfere with thinking.
Our cat does not eat lamb as he is not adapted to lamb, but he does eat a lot of duck purring to the skies.
that's parents' point ( I think ? )
The person I responded to seemed to seems to believe lions eating only poultry would develop nutritional deficiencies of some kind. Maybe that's true but I'm interested to learn if there are sources. Not just gut feel "they don't eat them in the wild so they can't do it".
Meat contains essential fats to various degrees while protein powder does not at all. Usually, protein powder ([1] as an example) is not exactly matched to the human profile of amino acids [2], that means extraneous amino acids will be converted to glucose and stored as fat.

Notice that ratio between leucine and methionine is 3/1 in consumption profile and is much higher in the whey protein profile. This leucine most probably will be wasted.
If we assume that lions' best diet is beef [1], then chicken [2] would be less optimal for them.

Look at the amino acid ratios. Leucine to valine ratio is about 0.66 for chicken and 0.8 for beef. This means that protein synthesis will be bound by valine in case of chicken and what is not used in the protein synthesis will be converted to glucose and then stored as fat. Chicken will be about 80% (0.66/0.8) as nutritious as beef, judging just by two essential amino acids ratio.
Whey protein most probably would bound muscle protein synthesis by methionine available, and make substantial (I think 40%) amount of calories from leucine in it to be converted to glucose. Two 33g servings of whey protein can be converted to 1g of fat, just from leucine alone.
Lions challenge the dominant male, and if they win, they kill all of their offspring and take all of their females.
Hopefully you are not doing that with every male you encounter that happens to be physically weaker than you.
You're badly misusing that amino acid data.
I'm afraid you're going to unlearn it, as humans are below big felines in the food chain.
I struggled a lot with my nutrition and eating "regular food" always mad me fat. I tried various keto and low carb variants but never made it work and always hit a wall after 2-3 weeks. UNTIL I discovered intermittent fasting. After having done the intermittent fasting for about 5 years I started another low carb/keto journey but this time I went all in on fat and protein. No holding back. And I also cut excessive vegetables (especially the raw stuff). So now I'm eating all the eggs, meat, butter, bacon as much as I want. About a year in. The results so far.. dropped 4kg body fat and put on 2kg of muscle.
I was asking for a source for this assumption. Lions in the wild eat gazelles, giraffes, zebras, and buffalo, not cattle. I guess there isn't a great source so I'll leave it.
It doesn't mean the diets of humans are biologically supposed to consist of huge amounts of meat.
Most apex predators are of course obligate carnivores. But humans are probably near the top because the use of weapons and tools makes us highly dangerous, so most land animals are wary of humans. Even many predators don't prey on humans for food.
(Although some large land predators do, mostly when they're desperate for food.)
Which is hilarious since current bro-science is that protein is the most filling macronutrient.
