# Protein Intake Guide

PROTEIN INTAKE: GOALS, ACTIVITY & BODY FAT Nutrition Reference  Educational Use Protein should match the tissue it supports, not just the number on the scale. Page 1 How Much Protein Do You Actually Need? Protein intake by fitness goal, activity level and body fat percentage For an average person with moderate activity, 1.5 to 2.0 g of protein per kg of bodyweight is a solid, evidence-based target. But the rule quietly breaks down at higher body fat. Multiply 2 g by a 110 kg bodyweight and you get 220 g, yet fat tissue doesn't need protein the way muscle does. A person with a lot of body fat and very low activity who forces down 200 to 250 g a day is eating far more than their body can use, and often gets bloated and constipated for it. This guide shows how to set a target that fits your goal, your activity and your body composition. 1. The Starting Point: Protein per kg of Bodyweight For people at a healthy body fat level GOAL / PROFILE ACTIVITY LEVEL PROTEIN (G PER KG PER DAY) General health Sedentary (desk job, little exercise) 0.8 - 1.0 Staying healthy and fit Light (daily walks, occasional workouts) 1.0 - 1.4 Average person training for fitness Moderate (3 to 4 sessions a week) 1.5 - 2.0 Building muscle Regular strength training 1.6 - 2.2 Losing fat while keeping muscle Moderate to high 1.8 - 2.2 Where the numbers come from: The official minimum of 0.8 g per kg only prevents deficiency. Sports nutrition guidance for people who train usually sits at about 1.4 to 2.0 g per kg, and muscle-building research suggests the benefit levels off around 1.6 g per kg, with up to about 2.2 g per kg covering nearly everyone. Example: a 70 kg person training moderately needs roughly 105 to 140 g a day.

Why Bodyweight Alone Fails at Higher Body Fat Protein supports lean tissue, not stored fat Muscle, organs, bone and skin are what protein maintains and repairs. Stored body fat needs very little. So as body fat rises, total bodyweight overstates how much protein you need. The fix is to base the number on lean body mass (everything that isn't fat) instead of the scale weight. STEP WHAT TO DO Step 1: Estimate body fat % Use a DEXA scan, a good body-composition scale, or skinfold measurements. All are approximate. Step 2: Work out lean mass Lean mass = bodyweight x (1 - body fat %). For 100 kg at 35% body fat: 100 x 0.65 = 65 kg. Step 3: Multiply by an activity factor Use the lean-mass table below. Round to a practical daily number. Step 4: Cross-check Protein per kg of your goal weight at about 1.4 to 2.0 g should land in a similar range. ACTIVITY LEVEL PROTEIN PER KG OF LEAN MASS Low activity 1.6 - 2.0 g Moderate activity 1.8 - 2.2 g High activity / hard training 2.0 - 2.5 g 3. Four Profiles, Compared The same "2 g per kg" rule gives very different answers PROFILE WEIGHT, BODY FAT, ACTIVITY 2 G x KG RULE BETTER TARGET HOW IT WAS WORKED OUT Average person 70 kg, 20% body fat, moderate activity 140 g 105 - 140 g Body fat is in a healthy range, so 1.5 to 2.0 g per kg of bodyweight works fine. Higher body fat 100 kg, 35% body fat, low activity 200 g 105 - 130 g Lean mass is about 65 kg. Calculated as 1.6 to 2.0 g per kg of lean mass. Obese, very low activity 115 kg, 42% body fat, very low activity 230 g 105 - 135 g Lean mass is about 67 kg. Same method: 1.6 to 2.0 g per kg of lean mass. Heavy but muscular 100 kg, 15% body fat, hard training 200 g 170 - 210 g Lean mass is about 85 kg, and 2.0 to 2.5 g per kg of lean mass is reasonable. Takeaway: The 100 kg and 115 kg profiles with high body fat and low activity land at roughly 105 to 135 g, about half of what the bodyweight rule suggests. The heavy, muscular 100 kg person genuinely does need 170 g or more. Weight alone doesn't tell you which one you are, body composition and activity do.

Why Very High Intake Can Backfire Especially with high body fat, low activity and a sudden jump ISSUE WHAT CAN HAPPEN Digestive load A lot of protein with little fibre or water can cause constipation, bloating and gas, especially if the increase is sudden. Crowding out other foods Protein-heavy plates push out vegetables, fruit and whole grains, so fibre drops just when it is needed most. Large single servings and shakes Big doses of whey concentrate (which contains lactose) or bars made with sugar alcohols often cause bloating and loose stools. Diminishing returns, extra calories Beyond roughly 2.2 g per kg, extra protein adds little muscle benefit, and protein still has 4 kcal per gram. 250 g of protein is 1,000 kcal, a big slice of a fat-loss calorie budget. Kidneys and medical conditions Research hasn't shown that high protein harms healthy kidneys. But anyone with kidney disease, or at risk of it, should only raise protein under medical advice. 5. Hitting Your Target Comfortably Simple habits that keep digestion happy TIP WHY / HOW Spread it across the day Aim for 3 to 5 servings of roughly 25 to 40 g, rather than loading up one or two huge meals. Build up gradually Raise intake over 1 to 2 weeks so your gut can adjust, instead of jumping straight to the target. Pair protein with fibre Keep vegetables, fruit, dal or whole grains on the plate so digestion stays regular. Drink enough water More protein goes hand in hand with more fluids, which helps prevent constipation. Whole foods first, shakes to fill gaps Eggs, curd, paneer, dal, fish and chicken come with other nutrients. Use powder for the remainder. Choose gut-friendly powders If dairy bothers you, try whey isolate or a plant protein, and avoid bars heavy in sugar alcohols. Take a short walk after meals Light movement after eating supports digestion and comfort. 6. When to Check With a Professional Some situations need individual advice, not a formula SITUATION WHAT TO DO Kidney or liver disease Protein targets need to be set by a doctor. Diabetes with complications, pregnancy, or older age with frailty Needs individualised guidance. Ongoing bloating, pain, constipation or changes in bowel habits Get checked rather than assuming it is only protein. Note: These are general ranges used in sports nutrition, not a personal prescription. Body fat estimates from scales and calipers are approximate, so treat every figure as a starting point and adjust based on progress, hunger, digestion and training. Consult a doctor or registered dietitian for advice specific to you.
