When you eat way beyond required amount with some specific health condition, for athletic reason etc. Is something that can be define as taking more than what is adequate in order to perform day-to-day activity without specific health problem or sports performance need, then it can be consider.
For example:
- 180g – 220g is 70g with something else, someone still needing 70g can eat something which has some grams of protein then it’s not a huge jump to add more
While a few high-protein meals shouldn’t cause problems for healthy people, eating a diet of regularly over-the-top protein may not do you a lot of good.

Why is having too much protein bad in your diet?
When you consume protein:
- The protein breaks down into amino acids.
- The amino acids are used to replace tissue, building muscle proteins.
- Excess amino acids are transformed into fuel or another use within the body, with excessive calories possibly resulting in fat storage.
Adding more protein alone won’t force your body to build limitless muscle. These are factors besides calories on muscle development too:
- Resistance training
- Recovery
- Adequate calories
- Sleep
- Overall nutrition
Safe Daily Protein intake
Knowing safe, reasonable protein amounts is more beneficial than reaching overly higher protein levels.
| Person | Recommended Daily Protein |
|---|---|
| Average healthy adult | Around 0.8 g per kg body weight |
| Recreational exercisers | 1.0–1.4 g/kg |
| Strength training | 1.4–2.0 g/kg |
| Older adults | Often 1.0–1.2 g/kg (depending on health advice) |
For example
An individual of 70kg may require: Sedentary: ~ 56g of protein daily Active gym member: 98-140 g daily Eating significantly higher then this has typically very small returns when looking to grow muscle
