How to lose weight: the complete beginner's guide

10 min read · EKCal Guide

Weight loss feels complicated. There are hundreds of diets, conflicting advice everywhere, and a billion-dollar industry built on making this harder than it needs to be. This guide cuts through all of it.

The one principle that everything else builds on

Weight loss requires a calorie deficit — consistently eating fewer calories than your body burns. Every diet that works, works because it creates this deficit. Low-carb, Mediterranean, intermittent fasting, vegan — they all operate through the same mechanism. Understanding this gives you the freedom to choose an approach that fits your life.

Step 1: Know your numbers

Before anything else, you need two numbers:

• Your TDEE — how many calories you burn per day at your current activity level. This is your maintenance calorie number.
• Your target — TDEE minus 300–500 kcal. This is how much you eat to lose weight.

Step 2: Eat enough protein

Of everything you can do nutritionally, getting adequate protein makes the biggest difference to weight loss quality. It keeps you full, burns more calories to digest, and protects the muscle you have. Aim for 1.6g per kg of bodyweight per day. For a 75 kg person, that's about 120g of protein daily. Good sources: eggs, chicken, fish, Greek yoghurt, lentils, paneer, tofu.

Step 3: Choose foods that fill you up

A calorie deficit doesn't have to mean constant hunger. The secret is choosing foods with high satiety — the fullness you get per calorie. Protein tops this list, followed by fibre-rich foods (vegetables, legumes, whole grains). Ultra-processed foods are engineered to bypass satiety signals — they're easy to overeat and should be minimised.

Step 4: Be consistent, not perfect

The diet you can sustain for 12 weeks beats the "perfect" diet you abandon after 2. One bad meal doesn't matter. One bad week barely matters. What matters is your average intake over months. Build an approach that fits your food preferences, social life, and schedule.

Step 5: Move more (without relying on it)

Exercise is excellent for health, mental wellbeing, and preserving muscle during weight loss — but it contributes less to the calorie balance than most people assume. Focus primarily on the "calories in" side. Walking is the most underrated tool: it burns calories without triggering the compensatory hunger that intense exercise often causes.

What to expect week by week

• Week 1–2: Rapid initial drop (mostly water weight). Don't be fooled — and don't be discouraged when it slows.
• Weeks 3–8: Steady fat loss. Clothes feel looser. Scale moves 0.3–0.5 kg/week.
• Weeks 9+: Progress may slow as your body adapts. Recalculate TDEE and adjust target downward by 50–100 kcal if stalled for 2+ weeks.
