Question 1

How much protein do I need per day?

Accepted Answer

For adults in a calorie deficit, meta-analyses converge on 0.7–1.0 g of protein per pound of body weight; up to 1.2 g/lb for muscle growth. A 170 lb person aiming for fat loss should target roughly 130–170 g protein per day.

Question 2

Is 1 gram of protein per pound of body weight really necessary?

Accepted Answer

For most people, no — 0.7–0.8 g/lb captures the vast majority of the muscle-preserving benefit in a deficit. 1.0–1.2 g/lb is the upper end for serious lifters or aggressive cuts. Going higher offers diminishing returns and just displaces other calories.

Question 3

Can eating too much protein damage my kidneys?

Accepted Answer

Not in healthy people. A 2020 systematic review found no adverse effects on kidney function from high-protein diets (up to 3 g/kg/day) in individuals with normal renal function. People with pre-existing kidney disease should consult a physician.

Question 4

What's the best time to eat protein?

Accepted Answer

Distribute it across 3–5 meals, roughly 25–40 g each. Total daily protein matters most; timing is a smaller factor. Post-workout protein within 2 hours is a mild bonus, not a requirement.

Question 5

How do vegetarians and vegans hit high protein?

Accepted Answer

Use tofu, tempeh, seitan, legumes, edamame, and a protein powder (soy, pea, or blend). Vary sources through the day to cover the amino acid profile. Vegans often benefit from adding 5–10% more total protein to compensate for slightly lower digestibility.

Question 6

Does protein help with weight loss?

Accepted Answer

Yes — three ways. It's the most satiating macronutrient (reduces hunger), has the highest thermic effect (your body burns 20–30% of protein calories digesting it), and preserves muscle mass in a deficit (which keeps metabolism higher).

Question 7

What are the best protein sources?

Accepted Answer

Complete-protein animal sources: chicken breast, turkey, lean beef, eggs, Greek yogurt, cottage cheese, fish, whey. Complete plant sources: soy (tofu, tempeh, edamame), quinoa, hemp seeds. Beans + rice, hummus + pita, and peanut butter + whole-grain bread pair incomplete proteins into complete ones.

Question 8

Do I need to eat protein right after working out?

Accepted Answer

The 'anabolic window' is 4–6 hours, not 30 minutes. If you ate protein within a few hours of training, you're fine. Total daily protein matters far more than exact timing.

Question 9

How much protein for a woman trying to lose weight?

Accepted Answer

The same per-pound targets apply regardless of sex: 0.8–1.0 g per pound of body weight during fat loss. A 140 lb woman should target roughly 110–140 g of protein per day.

Question 10

Is protein powder necessary?

Accepted Answer

No. It's a convenient way to hit your target when whole-food protein is impractical (busy morning, post-workout, travel). If you can hit your daily grams with food alone, powder is optional.
