Meal Distribution Tips
🍽️ Spread It Out
Aim for 20-40g of protein per meal across 3-5 meals. This maximizes muscle protein synthesis better than consuming most protein in one sitting.
🌅 Start Strong
Don't skip protein at breakfast. A protein-rich morning meal (25-35g) helps control appetite and supports muscle maintenance throughout the day.
🌙 Before Bed
Casein protein (from Greek yogurt, cottage cheese, or a casein shake) before bed can support overnight muscle recovery.

Frequently Asked Questions
How much protein do I need per day?
The RDA minimum is 0.8g/kg, but most research suggests 1.2-2.2g/kg for optimal body composition and health. Athletes and those building muscle should aim for the higher end (1.6-2.2g/kg).
What happens if I eat too much protein?
For healthy individuals, intakes up to 2.2g/kg are well-tolerated. Excess protein is either used for energy or converted. Very high intakes may strain kidneys in people with pre-existing conditions but haven't been shown to damage healthy kidneys.
What are the best high-protein foods?
Chicken breast (31g/100g), eggs (13g each), Greek yogurt (10g/100g), salmon (25g/100g), lentils (9g/100g cooked), and whey protein (25g per scoop) are all excellent sources.
Do I need protein powder?
No. Whole foods can provide all the protein you need. Powder is convenient and cost-effective, but not required. It's most useful when you're in a rush or struggling to hit your target.
Does protein help with weight loss?
Yes. Protein is the most satiating macronutrient, meaning it keeps you fuller longer. It also has the highest thermic effect (20-30% of its calories are burned during digestion), and helps preserve muscle during a calorie deficit.
