You don’t need a food scale to track your macros anymore. Take a picture of your food, upload it to an AI tool, and within seconds you have a reasonable estimate of the protein, fat, carbs and calories, all in one place. The old way, with a scale and a calculator, is obsolete for normal people like you and me.
What tracking your macros means
Tracking your macros means adding up, to the gram, how much protein, fat and carbohydrate you eat each day. Know those and you also know your calories.
The people most serious about getting in shape, the fitness models, bodybuilders and pro athletes, have always done this. Every ounce of food weighed. Every number calculated. They know their calories down to the calorie.
Why I used to tell people not to bother
Before AI, I was against macro tracking for regular people. It was too complicated and too much work. You weren’t going to weigh everything you eat, and you weren’t going to look up every ingredient in a ten-ingredient dish online and add it all up. So I recommended other ways to get in shape that didn’t depend on exact numbers.
Why a photo changes everything
With AI, the hard part is gone. You don’t weigh anything and you don’t look anything up. You take a picture and the AI does the math.
Listen: even if this is all you ever do, a photo of everything you eat uploaded to AI and those estimates added up, it will be far, far better than doing no tracking at all. You’ll know roughly what you’re eating every day, which most people have never known. Once you can see your numbers, you’ll be shocked at how much easier it gets to stay in a deficit.
How to start today
- Photograph everything you eat, snacks and drinks included.
- Upload it to an AI tool. Claude, Gemini and plenty of free AI tools can estimate macros from a photo.
- Add up your day and compare it to your goal.
That’s it. No scale, no calculator, no spreadsheet.
