💡 How It Works
Step 1: Your BMR is calculated using the Mifflin-St Jeor equation (the most validated formula, within 5–10% accuracy for most people).
Step 2: BMR is multiplied by your activity factor to get TDEE (Total Daily Energy Expenditure).
Step 3: Your chosen deficit is subtracted from TDEE. Protein is set first (to preserve muscle), then fat, with remaining calories going to carbs.
⚠ Note: If your calculated carbs fall below 50g, consider choosing a smaller deficit or lower protein target.

140 lb / 64 kg140g (560 cal)43g (387 cal)140g (560 cal)
160 lb / 73 kg160g (640 cal)49g (441 cal)142g (568 cal)
180 lb / 82 kg180g (720 cal)55g (495 cal)148g (593 cal)
200 lb / 91 kg200g (800 cal)62g (558 cal)148g (590 cal)
220 lb / 100 kg220g (880 cal)68g (612 cal)147g (588 cal)
250 lb / 113 kg210g (840 cal)72g (648 cal)155g (622 cal)
💡 Tip: For individuals above 220 lb / 100 kg with high body fat (over 30%), using 0.8–1.0g protein per lb of lean body mass (not total weight) often yields better macro balance. The calculator uses total body weight by default.

⚠ Recalculate regularly: As you lose weight, your TDEE drops. Recalculate every 10–15 lbs lost (roughly every 5–7 kg) to make sure your deficit and macros are still accurate. A person who was 200 lb at 1,950 kcal target might need to drop to 1,820 kcal after losing 15 lb.

The word “macro” comes from Greek roots, that shows “long” or “big” (so everything that appears great), heavy or especially visible. The point is that this word appears everywhere, when one starts to think. In computing it works one way, in food and nutrition otherwise, while photographers give it his separate spin.

For this word the setting plays big role.

What Macro Means in Computers, Food and Photography

In the computer range macro are usually tools for saving time. It is made up of a group of steps, that usually requires hand work, but they are combined and run automatically by means of one key press or menu item. Think about it as a recorder for your computer.

A recorder of macro catches the moves of mouse and keyboard, later them replays when needed. When one struggles with repeated works, it genuinely saves the life.

macro in Microsoft Excel well help to automate tasks, that happen regularly. While you create one, it saves your taps of mouse and key presses properly. One can create a VBA macro, that right away fills several pages, like this removing hours of boring work.

Excel itself has VBA built in, that holds codes directly. Almost every program of Office 365 supports macro, Word, Excel and others. You can either directly record a macro or write it in VBA from nothing.

Sometimes, when macro extends past some sequences, it is best to alter it into a proper function, because otherwise the cleaning becomes chatoic.

Windows machines offer three languages for scripting tasks: batch files, VBScript and PowerShell. Even so PowerShell beats, it is the most mighty option, because it can directly work with Windows and your programs.

Macro Commander is a Windows program, that cares about repeated tasks. It allows you create and control macro by means of warm keys, text shortcuts or mouse clicks, that puts text, images or other content in almost every app. Also there is MacroGamer, that does a similar task, but for video games, it stores and replays you’re actions.

Now we shift to the nutrition viewpoint. When food experts mention macro, they mean short for macronutrients, carbohydrates, fat and proteins. A split that works for many folks, like 40% carbohydrates, 30% proteins and 30% fat.

That ratio helps to stay full and energized, although for losing weight you need a calorie decrease. Protein is the most important. Aim around 1.2 to 1.6 grams each kilo of body weight, to keep muscle.

For folks with less active, home lifestyle, 45% to 60% carbohydrates and 20% to 35% fat work, but with smaller portions. There are macro calculators, that give personal numbers based on your age, activity andtargets.

And then we have macro photography, that forms his own niche entirely. Websites with focus on macro and close photography grew fast, thousands of threads and millions of page visits. Here folks share tips about tools and methods, share photos of insects and other little, detailed objects.
