One could say petr is an over thinker as well. Maybe you two are meant for each other
I am drastic simplifyer, believe me...

I’m honestly not seeing the controversy with this, or how this would change most of your practices.
It is pretty clear that we can augment the nutritional content of feeders by offering diets rich in certain vitamins and minerals. (Look at research by Finke and others). The “gutloading” chart lists several greens and veggies that are packed with vitamins and minerals and have favorable calcium to phosphorus ratios (there’s a nice chart in Mader’s Reptile medicine and surgery with some of this information). As long as our insects can digest this stuff, their nutritional value is improving and this can be passed to the chameleon
it seems there are some things on that chart that could be potentially harmful that @PetNcs takes issue with. If these things (almonds, etc) have potential for harm, they should be omitted entirely from the process
Gutloading (feeding Insects directly prior to feeding them to the chameleon) should Include things that chameleon can absorb and benefit from if we intend to use their gut as a vector for our chameleons nutrition, and he gives suggestions on what you can usefor this process. Correct me if I’m wrong, but he also concedes that dusting feeders may make “gutloading” unnecessary
so if you feed Your insects high quality foods that increase their nutritional content you have satisfied part one of his suggestions
If you would like to enhance their available nutrition, just prior to feeding your feeders gutload them with bee pollen, calcium, and /or multivitamin, or just dust them. As @nightanole noted earlier, calcium can kill the insects Over time. I think it causes constipation (don’t quote me on that), so do this only as a gutloading addition
unless your only feed your bugs once just before you feed your Cham, you’re really not changing anything. Just feed them and dust them
I don't take offense. But I also think that the way I look at it is pretty common for how others will see it. I did not understand what you meant about my logic lacks feneral niolohical... and maybe I don't need to know lol.
It is funny because out of all the people that have jumped in on this thread. I am very modest in how I gutload and what I use compared to others. I keep mine very simple.
But again thank you for taking the time to have the conversation.
I have never seen you off the mark.
I have never seen you off the mark.
I have no idea what you mean.
I have never seen you off the mark.
Thank you for the kind translation of the senseYou always make high quality posts. No sleepy posts.
Ok friends, shall we cut a distinction here?
Gutloading = The practice of feeding your bugs a bunch of healthy stuff just before feeding them off, in the hopes that this partially digested stuff gets to our chameleon via the insects’ gut contents.
Nutrient maximization = The practice of always feeding your bugs maximally nutritious food so that our bugs are at their most nutritious at the time of consumption. This need not be based on the gut contents of the bugs.
I’m happy to hear alternative names for option 2.
I second this, will ‘HQF’ work? (High quality feed)
These all recommendations have absolutely no scientific basis, they are repeated and parotted imaginations and formulations of people that dare to introduce to the community things that absolutely do not make sense and are not backed with any measurable experience and no science.
Because we do not have access to the vegetation present in the home ranges of chameleon habitats as commercial produce. Just because you can't get one specific plant does not mean that another plant with a similar nutrient profile is going to be "unnatural". It may not be the same but it can have the same benefits. Please do tell me how "natural" the clothes on your back are compared to your ancestors. This is not a good argument to just say because it's not the exact same thing that is it unnatural and therefore harmful.1. IT IS UNNATURAL - most of the shown ingredients you will never ever find in the stomachs of insects that are eaten by a Chameleons in the wild,
with few exceptions like maybe the juices of some fruits but definitely not apple... The reason is very simple, the insects living in areas that chameleons live in, have no access to this type of food and even if they would have, they would not eat it. So again, it is not natural.
All the concept of gut-loading, If it would be to increase the nutritional value of the feeder, is false. Because to increase the nutritional value the major part of the food inevitably must be digestible. And it is NOT.

Thanks for posting these papers. This is great evidence that high quality feeding of feeders increases their nutritional value.There is sure is a lot of conjecture and heavy handed statements without any scientific backing on this thread. Let me help with that.
They do actually.

We do not recommend citrus or almonds in gutload so not even sure why you feel that is a battle worth fighting. Crickets are not ingesting large parts of plants that remain intact, they are digesting it into nutrients first, which then the chameleons consume. So whether or not chameleons can digest plant matter is irrelevant because feeders can.
The scientific papers listed above say that nutritional value of feeders does increase depending on what is fed, which is the entire purpose of gutloading. Do you have scientific sources that say otherwise?
There are several papers that suggest that some chameleons regulate their uvb exposure depending on need. So, for example, panther chameleons given no dietary d3, will bask more. There’s a few pertinent articles sites in the bibliography of:I think this chart
shows an issue we have to deal with as chameleon keepersView attachment 280527
The column for chameleons is essentially blank due to the lack of data regarding wild diet and it’s nutritional value along with lack of research on their requirements.
I’ve heard some information regarding required dietary D3, but much of the rest of this is unknown
