Protein is not just for great skin, hair, and nails; it’s critical for health. Without it, you wouldn’t be able to repair damaged tissues, digest food, fight infections, build muscle and bone, create hormones, or even think and have a good mood.
Eating enough protein during the day allows you to maintain stable blood sugar so you can be focused and mentally sharp throughout the day.
Higher protein diets can help fight high blood pressure, diabetes, and osteoporosis. Not to mention protein’s great benefits for metabolism boosting, satiety (feeling full after a meal), and weight management.
Protein is important, that’s a given.
There are a few factors to consider when calculating how much protein we need. In this post, I’ll go through those calculations with you. You’ll also find a list of the amount of protein in some common foods.
How much protein is enough
Every body is different, so there isn’t a rule that applies equally to everyone. There are a few factors to consider when figuring out how much protein you need.
Start with the minimum recommendation of 0.8 g/kg (0.36 g/lb) per day.
So, for a 68 kg (150 lb) healthy non-athlete adult, this is about 55 g protein/day.
Mind you, this is a minimum to prevent protein deficiency. It’s not optimal for good repair, digestion, immune function, muscle/bone building, hormones, thinking and great moods. It’s not enough for athletes, seniors or those recovering from an injury, either. If you fall into one of these categories, you may need to increase the minimum protein intake to a higher amount within the recommended range. Aim closer to 1.3 g/kg (0.6 g/lb) per day.
More than likely your protein needs will fall between 0.8 g/kg and 1.3 g/kg per day. Which you can judge based on your activity level.
Athletes need more protein for their energy and muscle mass. Seniors need more to help ward off muscle and bone loss that’s common in old age. And injured people need more for recovery and healing.
How much protein is too much?
As with fat and carbohydrates, eating too much protein can cause weight gain. Extra protein can be converted into sugar or fat in the body.
The interesting thing about protein is that it isn’t as easily or quickly converted as carbohydrates or fat; this is because of its thermic effect. The thermic effect is the amount of energy required to digest, absorb, transport and store a nutrient. To digest protein, your body needs to spend energy (i.e., burn calories). More calories than when metabolizing fats or carbohydrates.
A good rule of thumb is to eat a maximum of 25g of protein at one time (the equivalent of 3-4 oz of cooked meat). This is the amount of protein that your body can digest and assimilate at one time. It’s a good idea to space your protein intake throughout the day.
If you’re concerned that high protein intake harms healthy kidneys, don’t be. If your kidneys are healthy, they are more than capable of filtering out excess amino acids from the blood. The problem only occurs in people who already have kidney issues.
Note: Plant proteins are especially safe for kidney health.
How much protein is in food?
- A 3.5 oz chicken breast has 31 g
- A 3.5 oz can of salmon has 20 g
- ½ cup cooked beans contain 6-9 g
- A large egg contains 6 g
- ¼ cup nuts contains 4-7 g
- 1 medium baked potato contains 3 g
Protein is an essential nutrient we should all get enough of. “Enough” is about 0.8 – 1.3 g/kg (0.36 – 0.6 g/lb) per day. If you’re a healthy non-athlete adult, you can aim for the lower level. If you’re an athlete, senior, or injured person, aim for the higher level.
Too much protein can cause weight gain, so it’s best to have just enough.
I’d love to know: Are you one of those people who needs more protein? Let me know in the comments.
Recipe (high-protein): Baked Chicken Breasts
4 boneless skinless chicken breasts
1 Tbsp. grapeseed oil
1 tsp salt
½ tsp black pepper
½ tsp garlic powder
½ tsp paprika
¼ tsp turmeric

Place the chicken breasts in the prepared dish. Brush on both sides with grapeseed oil.
In a small bowl, mix spices until combined. Sprinkle the spice mixture evenly over the chicken on both sides.
Bake for 15-20 minutes, or until the chicken is cooked through to at least 165°F at the thickest part.
Serve & enjoy!
Tip: Serve with a variety of coloured vegetables, or a salad!
