With AI glasses doing this automatically for you upon seeing what your eating without u having to do anything some people may be shocked to learn how many calories they consume daily.
Currently, it's too time consuming now for the majority to do (i use GPT via texting it or talking to it to keep track as I eat out daily at healthy chains) but if it was done automagically I believe it definitely would be a substitute to Ozempic. I bet some or more would use that easily captured data that's shown to them (in the glasses or on their mobile device) to strive, make and possibly compete with their friends/family to eat less calories and carry less weight on them (be healthier). You can train your body to eat less to a lot less and for some that would definitely help them shed weight. The glasses could as well deduct calories burned from your daily walk, jog, etc.
*Being downvoted hmmm do you think AI by seeing it can't via an image calculate the calories of a burrito bought from Chipolte and other chains? All chains have nutrition information on their websites now that GPT goes and fetches. As for home cooked prepared meals I have taken pics of my food via GPT and it seemed to come close.
