# Macronutrients Guide

UNDERSTANDING YOUR MACRONUTRIENTS Nutrition Reference  Educational Use General nutrition education, not a substitute for personalized medical or dietary advice. Page 1 Understanding Your Macronutrients Carbs, Fats, Fibre & Protein — What They Are, How They Work, and How to Eat Them Right Not all carbs, fats, or fibre behave the same way in your body — and knowing the difference helps you build meals that actually work for your energy, digestion, and long-term health. This guide breaks down the three core macronutrients, then goes deeper into the key distinctions people ask about most: simple vs complex carbs, saturated vs unsaturated fats, and soluble vs insoluble fibre. The 3 Macronutrients, At a Glance Macronutrient Role in the Body Energy (per gram) Common Food Sources Carbohydrates Primary energy source for the body and brain ~4 kcal/g Rice, roti, oats, fruits, legumes Protein Builds and repairs muscle, tissue, enzymes, and hormones ~4 kcal/g Eggs, chicken, fish, dal, paneer, soy Fats Energy storage, hormone production, and vitamin absorption (A, D, E, K) ~9 kcal/g Ghee, oils, nuts, seeds, avocado CARBOHYDRATES: Simple vs Complex Aspect Simple Carbs Complex Carbs What It Is Made of 1-2 sugar units (monosaccharides/disaccharides); a short, simple structure Made of long chains of sugar units (polysaccharides); a more complex structure Digestion Speed Broken down and absorbed quickly, causing a fast rise in blood sugar Broken down slowly due to fibre and starch content, giving a steadier glucose release Effect on Energy Quick energy burst, often followed by an energy dip as insulin responds to the spike Sustained energy over a longer period, with fewer blood sugar swings Food Examples Sugar, honey, fruit juice, white bread, sweets, soft drinks Brown rice, whole wheat roti, oats, millets, legumes, vegetables How to include it: Build most meals around complex carbs (rice, roti, millets, legumes) for steady energy, and keep simple carbs for occasional treats or a quick source of energy right after a workout. FATS: Saturated vs Unsaturated Aspect Saturated Fats Unsaturated Fats What It Is Fatty acid chains with no double bonds; typically solid at room temperature Fatty acid chains with one or more double bonds; typically liquid at room temperature

Page 2 Aspect Saturated Fats Unsaturated Fats Effect on Body Can raise LDL ('bad') cholesterol when consumed in excess, though moderate amounts fit a normal diet Can help improve cholesterol levels, especially when they replace saturated fats in the diet Food Examples Ghee, butter, coconut oil, fatty cuts of red meat Olive oil, groundnut oil, nuts, seeds, fish, avocado Key Point Not inherently harmful in moderation, but shouldn't be the dominant fat source Generally considered more heart-friendly when used as the primary fat source How to include it: Use unsaturated fats (nuts, seeds, fish, plant oils) as your main fat source day-to-day, while keeping saturated fats like ghee and butter for moderate, occasional use rather than the default cooking fat. FIBRE: Soluble vs Insoluble Aspect Soluble Fibre Insoluble Fibre What It Is Dissolves in water and forms a gel-like substance during digestion Does not dissolve in water; passes through the digestive tract largely intact How It Works Slows digestion, which helps regulate blood sugar spikes and can lower LDL cholesterol Adds bulk to stool and helps food move through the gut, supporting regular bowel movements Food Examples Oats, apples, citrus fruits, beans, flaxseeds Whole wheat, vegetable skins, nuts, wheat bran Key Point Especially useful for blood sugar and cholesterol management Especially useful for digestion and preventing constipation How to include it: Aim for both types daily rather than focusing on just one — whole fruits with the skin on, vegetables, legumes, and whole grains naturally provide a mix of soluble and insoluble fibre.

Individual needs vary based on health conditions, activity levels, and goals — consult a registered dietitian or doctor for advice specific to you, especially if you have diabetes, high cholesterol, or a digestive condition.
