How much protein do I need to lose weight?

A common evidence-based range is 0.7 to 1g of protein per pound of goal body weight per day while losing weight. Cal360 calculates a personal gram target from your stats and goal, for example 120g per day, and tracks it automatically.

Why does protein matter more than other macros in a deficit?

In a calorie deficit, adequate protein protects muscle so the weight you lose is fat, and it's the most filling macro, which makes the deficit easier to sustain.

What's the easiest way to track protein?

Use an app that logs protein automatically with every entry. In Cal360, photo scans, voice logs, barcode scans, and searches all record protein, and your dashboard shows a live protein bar against your daily gram target.

How to Hit Your Protein Goal Every Day (Without Living on Chicken)

If calories decide whether you lose weight, protein decides what you lose. Hit your protein in a deficit and the scale drop is mostly fat; miss it consistently and you give up muscle too. Here's your number, why you're probably under it, and the system that fixes it.

Your protein number

A practical, evidence-based range while losing weight is 0.7 to 1 gram per pound of goal body weight per day. Cal360 does this calculation for you during onboarding. A typical plan looks like 1,920 calories with 120g protein, and it shows the gram target on your dashboard next to carbs and fat. (Curious how the whole plan is built? See How Many Calories Should I Eat a Day?)

Why protein is the priority macro

It protects muscle in a deficit. Your body needs a reason and the raw material to keep muscle while losing weight. Training is the reason, and protein is the material.
It's the most filling macro. Higher-protein meals blunt hunger, which makes your calorie target dramatically easier to live with.
It costs calories to digest. A meaningful slice of protein's calories are burned just processing it.

Why most people undershoot

Protein rarely fails at dinner. It fails at breakfast and lunch. A pastry and coffee (3g), a salad (12g), and suddenly you need 90g from one evening meal, which nobody eats. The fix is distribution: aim for 25 to 40g per meal, starting with the first one.

The Cal360 protein system

Know your live number. Your dashboard's protein bar (e.g. 38/148g) tells you where you stand before every meal, with no math and no memory required.
Log everything effortlessly. Photo scans, voice logs, and barcode scans all capture protein automatically.
Let the meal plan do the heavy lifting. Cal360's High Protein meal plan, think Easy Chicken Burritos at 622 calories, is crafted with nutrition experts and matched to your calorie target, so hitting your grams is the default, not a daily project.
Check the bar before dinner. If protein is lagging, dinner is the protein-forward option. That single glance is the whole habit.
