Weight loss is simple in theory — burn more than you eat. But 95% of diets fail because people follow approaches that are too extreme, too complicated, or based on myths. This guide gives you only the science-backed methods that produce lasting results.
Step 1: Understand the Calorie Deficit
A calorie deficit is the only proven mechanism for fat loss. Every diet — keto, IF, low-fat, paleo — works because it creates a calorie deficit, not because of any magic property of the diet itself.
The Formula:
Your TDEE (maintenance calories) − 300 to 500 = daily calorie target for weight loss
500 cal/day deficit × 7 days = 3,500 calories = ~1 lb fat lost per week

❓ Weight Loss FAQ
Q: How fast can I realistically lose weight?
A: A safe, sustainable rate is 0.5–2 lbs per week. Faster loss often means losing muscle and water, which slows your metabolism. A 500-calorie daily deficit produces ~1 lb/week of fat loss.
Q: Do I need to exercise to lose weight?
A: No. Diet accounts for 80% of weight loss. Exercise helps preserve muscle and boosts mood, but a calorie deficit through food alone produces significant fat loss. Walking 30 min/day adds ~150–200 calories burned.
Q: What is a calorie deficit and how big should mine be?
A: A calorie deficit means eating fewer calories than you burn. For most people, 300–500 calories/day deficit is sustainable. Larger deficits (700–1000 cal) accelerate loss but increase muscle loss and hunger.
Q: Why did I stop losing weight after 2 weeks?
A: Most early 'stalls' are water retention from increased carbs, sodium, or hormonal fluctuations — not real fat gain. Weigh yourself daily and take the weekly average. True plateaus happen after 3–4 weeks of no change.
Q: What should I eat to lose weight fast?
A: Focus on high-protein foods (chicken, eggs, Greek yogurt), vegetables (low calorie, high volume), and limit ultra-processed foods. Protein is the #1 most satiating macronutrient and preserves muscle during a deficit.
Q: How many calories should I eat to lose weight?
A: Start with your TDEE (Total Daily Energy Expenditure) minus 300–500 calories. Most women lose weight on 1,400–1,700 cal/day; most men on 1,700–2,200 cal/day. Never go below 1,200 (women) or 1,500 (men) without medical supervision.
Q: Is intermittent fasting better than regular dieting?
A: Neither is superior — both work by creating a calorie deficit. IF works best for people who prefer skipping breakfast. Regular eating works better for those who get too hungry fasting. Pick whichever you can stick to.
Q: How do I track calories without an app?
A: Scan meals with our AI food scanner — take a photo and get instant calorie and macro counts. No manual logging, no database searching. Takes 3 seconds per meal.
