To lose 0.5 kg per week, you need a daily deficit of about 500 kcal (500 \u00d7 7 = 3,500 kcal \u2248 0.5 kg). To lose 1 kg per week, double it to 1,000 kcal \u2014 which is aggressive but doable for larger people.<\/p>\n<p>Do not go below:<\/p>\n<ul>\n<li><strong>1,500 kcal\/day<\/strong> for men (or you risk muscle loss and nutrient deficiency).<\/li>\n<li><strong>1,200 kcal\/day<\/strong> for women.<\/li>\n<\/ul>\n<p>Below these numbers, your body slows metabolism, loses muscle, and binge cycles. This is why &#8220;eat 800 calories a day&#8221; diets fail \u2014 they are biologically unsustainable.<\/p>\n<h2>What a 0.5\u20131 kg\/week Plan Looks Like<\/h2>\n<p>You do not need to count every calorie.

Aim for:<\/p>\n<ul>\n<li><strong>Protein:<\/strong> 1.2\u20131.6 g per kg of body weight per day (about 90\u2013130 g for a 80 kg person). This preserves muscle and keeps you full.<\/li>\n<li><strong>Fiber:<\/strong> 25\u201330 g per day from vegetables, legumes, whole grains.<\/li>\n<li><strong>Water:<\/strong> 2\u20133 liters. Thirst is often mistaken for hunger.<\/li>\n<li><strong>Whole foods:<\/strong> 80% of calories from unprocessed sources.<\/li>\n<\/ul>\n<h2>The Scale Lies \u2014 Use These Metrics<\/h2>\n<p>Weight fluctuates 1\u20132 kg daily due to water, sodium, hormones and bowel movements. Judge trends over weeks, not days:<\/p>\n<ul>\n<li><strong>Weekly weigh-in:<\/strong> Same time (morning, empty), same clothes.<\/li>\n<li><strong>Measure waist:<\/strong> Once a month. A shrinking waist matters more than the number.<\/li>\n<li><strong>Progress photos:<\/strong> Monthly, same lighting and pose.<\/li>\n<li><strong>Clothes fit:<\/strong> A belt hole or looser jeans is real progress.<\/li>\n<li><strong>Energy and strength:<\/strong> Can you walk up stairs without puffing? Lift heavier? Sleep better?<\/li>\n<\/ul>\n<h2>Why Plateaus Happen<\/h2>\n<p>After 4\u20138 weeks, weight loss stalls. This is normal \u2014 your smaller body burns fewer calories. Do not panic or cut more food. Instead:<\/p>\n<ul>\n<li>Increase movement by 1,000 steps per day.<\/li>\n<li>Add one strength session (muscle burns more calories at rest).<\/li>\n<li>Reassess portion sizes \u2014 your portions have shrunk with you.<\/li>\n<li>Take a diet break for 1\u20132 weeks at maintenance calories. This resets hunger hormones and metabolic adaptation.<\/li>\n<\/ul>\n<h2>Common Myths<\/h2>\n<p><strong>Myth:<\/strong> I need to lose 10 kg fast before an event.<br \/>\n<strong>Reality:<\/strong> Rapid loss is mostly water and muscle. A 2\u20133 kg real-fat loss over 4 weeks looks and feels better than 8 kg of water weight.<\/p>\n<p><strong>Myth:<\/strong> Carbs make me fat.<br \/>\n<strong>Reality:<\/strong> Calorie deficit determines weight loss. Whole-grain carbs (oats, rice, sweet potatoes) are part of a sustainable diet.<\/p>\n<p><strong>Myth:<\/strong> I can spot-reduce belly fat.<br \/>\n<strong>Reality:<\/strong> Sit-ups strengthen the muscle but do not burn the fat covering it. Full-body fat loss reveals the muscle underneath.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<p><strong>Q: Why did I lose 2 kg in the first week?<\/strong><br \/>\nWater weight. Carbohydrates store water (1 g glycogen = 3 g water). The first week is mostly fluid. Real fat loss starts after that.<\/p>\n<p><strong>Q: Can I lose weight without exercise?<\/strong><br \/>\nYes, through diet alone. But exercise preserves muscle, improves mood and dramatically improves long-term maintenance. People who exercise keep weight off far better.<\/p>\n<p><strong>Q: What if I have not lost weight in 3 weeks?<\/strong><br \/>\nCheck the details: Are hidden calories creeping in? Alcohol? Large portions? Better yet, get a body composition check or measure your waist.<\/p>\n<p><strong>Q: Is intermittent fasting necessary?<\/strong><br \/>\nNo. It is one tool for calorie control, not magic. Some people find it easy; others hate it. Use what fits your life.<\/p>\n<p><strong>Q: Should I take a break from dieting?<\/strong><br \/>\nYes \u2014 after 8\u201312 weeks, eat at maintenance for 1\u20132 weeks. This prevents metabolic slowdown and burnout.<\/p>\n<p><strong>Q: What is the fastest safe rate?<\/strong><br \/>\n1% of body weight per week. For a 100 kg person, that is 1 kg\/week. For a 60 kg person, 0.5 kg\/week.<\/p>\n<h2>References<\/h2>\n<ol>\n<li>Centers for Disease Control and Prevention. <em>Losing Weight.<\/em> https:\/\/www.cdc.gov\/healthy-weight-loss\/<\/li>\n<p>National Institute of Diabetes and Digestive and Kidney Diseases. <em>Prescription for Weight Loss.<\/em> https:\/\/www.niddk.nih.gov\/health-information\/weight-management<\/li>\n<p>National Weight Control Registry. <em>Research Findings.<\/em> https:\/\/nwcr.ws\/<\/li>\n<p>Hall KD et al.
