How Much Protein Do You Actually Need Per Day?

Protein gets talked about a lot in fitness circles, but the average person eating three hawker meals a day often isn't getting nearly enough of it. That matters more than you might think. Not just for building muscle, but for staying full, supporting your metabolism, and maintaining a healthy body composition over time.

The amount you need depends on your body weight, how active you are, and what you're trying to achieve. This guide gives you the numbers, explains where they come from, and shows you how to hit your target eating the food you already enjoy.

Why Protein Matters

Protein does three things that are particularly relevant when you're managing your weight.

First, it builds and maintains muscle. When you're in a calorie deficit, your body can break down muscle for energy if protein intake is too low. Enough dietary protein acts as a signal to hold onto lean mass while losing fat, which is exactly what you want.

Second, protein is the most satiating macronutrient. It keeps you fuller for longer compared to the same number of calories from carbohydrates or fat. Higher protein intake at meals naturally reduces the tendency to overeat, without requiring willpower or restriction.

Third, protein has a higher thermic effect than other macros. Your body burns more calories digesting it compared to carbs or fat, around 20 to 30% of its calorie content versus 5 to 10% for carbs and 0 to 3% for fat. It's a modest effect but it's real.

How Much Protein Do You Actually Need?

The official minimum recommendation from the World Health Organisation is 0.8g of protein per kilogram of bodyweight per day. That's the amount needed to prevent deficiency in a sedentary person. It's a floor, not a target.

For people who exercise regularly, want to lose fat while preserving muscle, or are over 50 (when muscle loss accelerates), the research consistently points to a higher range.

For most people in Singapore who exercise a few times a week and want to manage their weight, the 1.2 to 1.6g per kg range is a practical and well-supported target.

A Quick Example

That might sound like a lot if you're not currently tracking. But it's achievable with three meals a day when you choose protein-forward options.

High-Protein Asian Foods

You don't need chicken breast and protein shakes to hit your protein goals. Asian cuisine has plenty of excellent protein sources that are affordable, widely available, and genuinely enjoyable to eat.

Food	Serving	Protein	Notes
Chicken breast (grilled)	100g	31g	Excellent lean source, works with most Asian flavours
Fish fillet (steamed)	100g	22g	High protein, light in calories, easy to prepare
Tempeh	100g	19g	Also high in fibre; great plant-based option
Edamame	100g (shelled)	11g	Good snack or side, complete protein source
Firm tofu	100g	10g	Versatile, inexpensive, widely available
Egg (whole)	1 large (50g)	6g	Affordable and convenient; have 2 to 3 per meal

A Sample High-Protein Asian Meal Plan

Here's what hitting around 110g of protein per day could look like on a typical Singapore eating day:

• Breakfast: 2 soft-boiled eggs with kaya toast (about 14g protein) or a bowl of congee with minced pork and century egg (about 18g protein)
• Lunch: Sliced fish soup with tofu and a small bowl of rice (about 35g protein), or chicken rice with steamed chicken breast (no skin, about 30g protein)
• Dinner: Steamed fish with stir-fried tofu and vegetables over rice (about 40g protein), or a bowl of ban mian with minced pork and an egg (about 30g protein)
• Snack if needed: Edamame 100g (11g protein) or two hard-boiled eggs (12g protein)

That combination gets you comfortably into the 100 to 120g range without any dramatic changes to how you're already eating. The main adjustment is being deliberate about including a proper protein source at every meal, rather than letting a meal be mostly rice and vegetables.

Practical Tips for Hitting Your Target

• Make protein the first thing you plan at each meal. Decide on the protein source, then build the rest of the meal around it.
• Don't skip the egg. An egg is one of the most efficient protein sources in existence. Adding one or two eggs to any meal costs very little in calories and adds meaningful protein.
• Choose fish over processed meats when you can. Fish is high in protein, generally lower in calories, and provides omega-3 fatty acids that processed meats don't.
• If you're vegetarian, tofu, tempeh, and edamame are your core protein trio. A combination of all three across the day makes it much easier to hit 80 to 100g of plant-based protein.
• Track your protein intake using the HealthCalcAsia calculator for at least a week to see where you're actually landing. Most people are surprised to find they're getting 40 to 60g less than they think.

Protein is probably the most impactful single change you can make to your diet if you're currently not tracking it. Getting enough makes it easier to lose fat without losing muscle, easier to feel satisfied at meals, and easier to maintain a healthy weight long term. And with the range of protein-rich food in Asian cuisine, there's no need to force down plain chicken and broccoli to get there.

Protein does not only build muscle, it also supports healthy skin, and Glow Guide Asia has a guide on eating for your skin worth reading.

Always consult a healthcare professional before making significant dietary changes. People with kidney disease or certain medical conditions may need to limit protein intake and should seek specific medical advice.
