How can you use ChatGPT as a nutritionist to track calories and macros?

Short answer: Sam Nadler says he replaced MyFitnessPal with a ChatGPT project: he sends a voice note or photo of each meal and it returns calories, protein, carbs and fat, gives daily summaries and suggests what to eat later.

Sam Nadler [9:54]: Alright. Let's move on to our next segment where we typically cover a tool of the week, and it's, usually a lesser known tool that that maybe people are unaware of. But this week, we're covering, ChatGPT, but we're covering maybe less common use cases for ChatGPT. And, for me, I'll jump into how I have a less common use case, and I've started it fairly recently for the, like, the last couple weeks, and it's actually had a pretty positive impact on me. I've basically been using ChatGPT as a nutritionist, and I've gone through phases of using different mobile apps to track calories or track macros. And, historically speaking, I'll do it for a period of time and then, kind of stop and then do it again and then stop. One of the apps I've used the most is MyFitnessPal just to track calories, and, it's for the most part, does its job. It took a while to kind of input exactly 1.5 cups of rice, what I think is five ounces of grilled chicken. So it's it's a little bit more you know, it wasn't horrible, a bit more cumbersome. But, since the July, I've basically been using a thread on OpenAI to track my calorie intake and macros, and it's been super simple.

Sam Nadler [11:30]: I just voice noted in every time I eat something, or I just take a picture of the product. Doesn't even have to be the barcode. It pulls up the exact calorie count, the exact amount of proteins, carbs, fats, whatever. But it also will give me tips on what I can eat later in the day if I'm trying to hit my calorie and macro account. So, yeah, I mean, several times, it's just been as easy to upload a picture, give it a little bit of context in a voice note, and it will, to say, hey. Roughly, this is a lunch of 460 calories, 42 grams of protein, 57 grams of carbs, which is largely the rice, eight grams. I've done just normal. Here's my final update for Thursday, July 10. It gives me all kind of a summary. Calories, I had a big deficit that day. Net calories was strong. Protein, I could've always could eat more protein. Fat was low. This is one of my better days. I've had some worse Things where I

Sam Nadler [12:40]: Had, takeout

Jordan Metzner [12:43]: Some ice cream.

Sam Nadler [12:45]: Some ice cream, pineapple dessert here. This was I wanted to eat dessert, I think, here, and it said, some smart dessert options, whey protein mousse, ratio yogurt plus berries. This is all things I have too. It began to learn things that I, like, usually I'm eating and suggesting it. And, I asked a stupid question. Can I eat some pineapple for dessert? Yes. Of course. One thing I have noticed, it will

Jordan Metzner [13:16]: May I have some pineapple, please?

Sam Nadler [13:19]: It will and here's another picture of dinner I had with just with a quick voice note. And, for the most part, I think it captures everything. You know? Here's from the picture, zucchini, carrots, red onion, mushrooms, broccoli. You know? And, a, it's pretty easy just to do this on mobile. I don't have to pay anything for the macro counter. And, one thing I have noticed that I think is pretty funny, it will never tell me no even when I'm like, yeah. I kinda want some ice cream. It's like, well, you can eat some ice cream.

Jordan Metzner [13:52]: Yeah. You probably shouldn't, but go for it.

Sam Nadler [13:55]: But I think, if you know, obviously, MyFitnessPal is has been really impactful for some people to count their calories. And I there are times when I'm more fitness or dietary focused, I do wanna count my calories. I do wanna track my macros. There are times when I'm not, but it's just one use case that I thought was pretty impressive. Could you take this out of ChatGPT? Probably. I just don't see the need to. Could you build your, like, your own custom little Personal

Jordan Metzner [14:26]: Nutritionist. Yeah.

Sam Nadler [14:27]: Yeah. But, I keep it within a project. It, like, knows my history, and, that I don't really see any need to. I'm not looking to, like, commercialize it.

Jordan Metzner [14:37]: I mean, that's interesting because it makes, like, One ChatGPT conversation is like a mini application. Right? And now it's not a conversation to you anymore. It's actually like a full on end to end application. It just sits inside a conversation layer, which I think is, really interesting because now you kinda wanna pull it out. And ChatGPT can maybe figure out that you're kind of using it as an application and maybe wrap some nicer UI around it or maybe better accessibility, like a website link or something.

Sam Nadler [15:03]: Exact yeah. That could be interesting. Could I pull out the conversation to be a direct link on my phone? I mean, it's usually one of the top projects, top conversations in my thread just because I've been updating it a lot. But yeah.
