Understanding the Protein Intake Calculator
Protein is the building block your body uses to repair and grow muscle, and getting enough is essential whether you are training hard, losing weight, or simply staying healthy. This calculator estimates your daily protein target based on your body weight and goals.
How much you actually need
While the minimum to avoid deficiency is low, optimal intake for active people and those losing weight is considerably higher — commonly 0.7 to 1 gram per pound of body weight. Higher intakes preserve muscle during a calorie deficit and support recovery from training. Older adults also benefit from more protein to counter age-related muscle loss.
Timing and sources
Spreading protein across the day in moderate servings is generally more effective than loading it all into one meal. Quality sources include lean meat, fish, eggs, dairy, legumes, and tofu. If whole foods fall short, a protein supplement can help close the gap, but food-first is the better default for most people.
Tips & things to know
- •Spread protein across several meals rather than one large serving.
- •Higher protein helps preserve muscle while dieting.
- •Whole-food sources should come first; supplements fill gaps.
