10k Calorie Challenge - Found this quite interesting

Graelwyn75

Video exploring how much fat is potentially gained when someone eats 10k calories in a day as opposed to their usual intake. I found it fairly informative, but others' views might differ.

Yeah, imagine he had one heck of a food baby from that lot.

I like to watch the 10k challenges, but it really shocks me at times how these people can eat so much. If I eat an extra slice or two of pizza after I start to feel full I feel bad and can feel it through the next morning! I've always wondered if they gain weight afterwards so that was an interesting watch.

It was very interesting particularly where he said permanent fat gain is more a result of prolonged overeating. Just like weight loss is a result of prolonged undereating. I wish more people would get that it's not about what you ate today so much as how/what you eat over time that matters. It always bugs me to see posts about someone eating over their calories at a party and did they blow their whole diet.

I was expecting to see some "after" pictures and was disappointed when he forgot to do that. He was probably ready to purge at that point though and just wanted to end the video. He looked rough.

And it was cool to see that he's at my alma mater, the University of South Florida. GO BULLS!

Wouldn't want to use the bathroom after him the next day, that's for sure.

There was a really good article/study posted earlier this year, unfortunately a quick search/google isn't bringing it up.

Given the use of the word "SCIENCE" (in all caps nonetheless) in the title, he made damn unscientific assertions and extrapolations of the results of the scientific papers well beyond reason. It's clear he has limited understanding of biology and how to extrapolate scientific data.

1. He states that in the study of a 1000/calorie/day overfeed, the average was approximately 300 calories/day of extra TDEE. He then extends this in a linear fashion for a 7000 cal/day overfeed. TDEE increases would not be expected to increase linearly like this as there is an upper limit to how high TDEE would naturally increase.
2. He extrapolates the fat gain based on the initial fat gains, but the lower fat gain in the higher carb group are due to energy from carbohydrates being stored as glycogen initially. Glycogen stores are limited (hence the need to fuel during a marathon, you cannot store enough glycogen to maintain race pace for 26.2 miles), so as you go higher and higher in calorie excess, you can no longer store any further glycogen. The remainder will be stored as fat.
3. He doesn't seem to mention that the reason the fat storage converges for both groups is because of the above. As glycogen stores hit their upper limit, all remaining energy storage is in body fat stores. Given a large overfeed like this, it's expected his fat storage over the subsequent days would be higher than normal as his glycogen reserves are full. Just looking at fat storage over the very short term is losing the forest from the trees.

I eat around the same amount (3000/day), and the most I've been able to reach is 9000 calories in a day thus far since I've been tracking. I felt full to the point of feeling a bit ill at that point. I could have reached 10k for the day, but it would not have been enjoyable.

ETA another little nit: he says the cooking spray is 0 calories when it's only labeled as such because the serving size is something like 1/15 of a second spray which is fairly well known information for experienced calories counters... it's just oil in a spray can. He then proceeds to put at least 100 calories worth of oil in the pan.

I take it a step further and do a 10K calorie challenge while walking 10K steps. My body has no idea what it should do.

His girlfriend did a 10k challange and aftermath video which was also very interesting!
