From TodayYou Have Your Own AI Nutritionist
As a programmer who works with computers every daymy biggest pain point is an irregular dietEating too much takeout makes me gain weightcooking for myself means I don't know how to combine ingredientsand trying to lose weight always backfiresThat was until I discovered this AI nutritionist skill—I really felt like I wish I had found it sooner.
This skill comes from the bivex/hu-claude repository on GitHubIt's a self-improving nutrition assistant designed specifically for AI systemsIts standout feature is that it gets smarter over timeAfter each interactionit learns your preferences and gradually adjusts to the diet plan that suits you best.
To be honestI've used many diet apps beforebut most of them are based on fixed templatesYou input your height and weightand they give you a standard diet plan without any consideration of whether you actually like the foodThis AI nutritionist is different—it really remembers what you sayFor exampleI told it I hate green peppersand the second time it recommended recipesthere were no green peppers at allThat little detail touched me.
Let's First See What It Can Do
Let's briefly list its core features:
- Daily Menu Generation: Automatically pairs breakfastlunchdinnerand snacks based on your calorie goals.
- Real-time Nutritional Calculation: You input any food itemand it provides detailed data on proteincarbsfatfiberand vitamins.
- Diet Log Analysis: Record what you ate throughout the dayand it generates a nutrition report telling you where you exceeded or fell short.
- Goal Tracking: You can log weight changesbody fat percentageand muscle massIt will help you analyze trends.
- Special Needs Support: For conditions like diabetes requiring low-GI dietsor for vegetariansyou can set corresponding modes.
What surprised me most is its self-optimization mechanismEvery time I give feedback like "Today's lunch portion was a bit too much" or "I felt hungry in the afternoon and wanted a snack," it quietly records it and takes it into account for the next adjustmentOver timeit almost becomes an old friend who understands you.
Installation Is Actually Not Difficult
Although this is an open-source project on GitHubinstallation doesn't require any programming backgroundThe prerequisite is that you have a Node.js environment on your computer (if notjust go to the official website and download it—it's simple).
Open your terminal (on Windowsit's CMD or PowerShell; on Macit's the Terminal app) and directly copy the following command:
npx skills add https://github.com/bivex/hu-claude --skill dietitianWait for it to finishand the installation is completeThen you need to run it in an environment that supports this skill—for exampleclick the "Run in " button on the relevant platform to use it immediatelyOf courseyou can also write a simple script to call itbut we won't elaborate on that today.
The first time you launch itit will ask you several questions: your genderageheightweightactivity level (sedentary or often exercise)and health goals (lose weightbuild musclemaintain health)Fill them in carefully so the first recommendation is accurateYou can update the data anytime later.
Real Experience After Two Weeks of Use
I used it for two full weeksThe biggest change is that previously I agonized every noon over what to eat; now I simply ask the AI nutritionist what it recommends for todayand it gives suggestions based on my remaining calories and nutritional gapsFor exampleif it finds I had too little protein at lunchit will recommend high-protein dishes like stir-fried broccoli with chicken breast.
Another very practical feature is food substitutionFor instanceif I don't feel like eating rice todayI can directly ask "What can I substitute for rice?" It will tell me sweet potatoescornor buckwheat noodles are all optionsand automatically adjust the nutritional dataIt feels like having a nutritionist sitting next to you flipping through recipe books.
Ohand its diet log feature is quite interesting tooAfter each mealinput what you ateand the system automatically estimates the nutritional contentAt firstI worried it might be inaccurateso I used a kitchen scale to weigh things for a few days and compareI found the error was within 10%which is perfectly acceptableMoreoverthe more you use itthe more accurate its estimates for common foods become.
A Few Points to Note
Even though this AI nutritionist is impressiveit is not a real doctorIf you have a serious medical condition (such as kidney disease requiring strict protein control)or if you are taking medicationit is recommended to consult a professional physician firstand treat the AI advice as a reference rather than the sole basis for decisions.
Additionallyits self-improvement relies on continuous interactionIf you use it for two days and then leave it asideit won't be able to learn your habitsIt's best to persist in recording your diet and feedback every dayAfter a weekyou'll notice it understands you more and more.
One last tip: Interact with it every morning after waking up and have it generate your diet plan for the dayThenbefore bedspend a minute recording what you ateIf you keep this upyou'll gain a very clear understanding of your dietary structureI used to have no idea how much sugar I consumed daily; now I at least know.
That's itI hope this helps youIf you have any good dietary methodsfeel free to share and discuss in the comments!
