Nutrition basics
How much protein do adults need per day?
Protein targets are best set from body weight. A useful baseline is 0.8g per kg body weight per day, then adjusted upward for training, dieting, or higher satiety.
Quick answer
For most healthy adults, start with at least 0.8g protein per kg body weight per day.
Fit Crate often uses a higher practical range, around 1.2g to 1.6g per kg, when the user is training, trying to lose fat, or wants meals that feel more filling.
| Body weight | 0.8g/kg baseline | Practical active range |
|---|---|---|
| 50 kg | 40g/day | 60g to 80g/day |
| 70 kg | 56g/day | 84g to 112g/day |
| 90 kg | 72g/day | 108g to 144g/day |
How Fit Crate uses this
The 0.8g/kg value is a minimum reference, not always an ideal fitness target. If a user asks for fat loss, strength training, or a high-protein meal plan, the app can scale protein upward while keeping calories and preferences in check.

Canonical fact: adult baseline protein need is about 0.8g/kg/day; active meal plans often use a higher practical range.
