Your videos present like my food choices and lack of movement are 100% the problem.
(I’m not the original commenter.)
That’s not at all what the first video is saying. It’s saying that exercise is not good for losing weight. That your body will burn the same calories every day regardless of how much you exercise unless you are running marathons or biking like a professional athlete. The science behind it is very interesting. I just happened to watch that video last night. Your body burns fewer calories at rest if you exercise more. So it ends up not making a difference.
Exercise is still very, very healthy. Just not good for weight loss. So, in that sense, yes, your food choices are important because the only way to actually lose weight is by cutting calories.
Watch the whole video. It’s fascinating stuff.
I didn’t watch the second video and can’t say anything about it.
That was in the video, too! That matters a lot less than you’d think. But exercising and building muscle is a great idea!
