How to lose 50 lbs quickly depends on what you mean by “quickly.” The CDC says a safe rate is 1 to 2 pounds per week, which means losing 50 pounds takes 25 to 50 weeks. That’s 6 to 12 months of work. Anyone promising faster results is selling you something that won’t last.
Here’s what actually works, backed by research from universities and medical centers across the world.
How long does losing 50 pounds actually take?
Losing 50 pounds takes 25 to 50 weeks at a healthy rate of 1 to 2 pounds per week. That’s 6 to 12 months for most people. A 2024 study from multiple research databases found that people who lost weight at this rate kept it off better than those who crashed through it faster.
The math is simple. You need a calorie deficit of 3,500 calories to lose one pound of fat. For one pound per week, that’s 500 calories less each day. For two pounds per week, you need a 1,000 calorie daily deficit.
Studies show that bigger deficits don’t work better long-term. A 2016 review in Obesity tracked people over multiple years and found that extreme calorie restriction led to muscle loss, slower metabolism, and weight regain. The people who lost weight slowly kept it off.

Download FreeWhat calorie deficit do you need to lose 50 pounds?
You need a 500 to 1,000 calorie daily deficit to lose 50 pounds. A 500 calorie deficit gets you 1 pound per week, and a 1,000 calorie deficit gets you 2 pounds per week. Research from the National Institutes of Health shows this range preserves muscle while burning fat.
The trick is not to cut calories too hard. When you drop below 1,200 calories per day for women or 1,500 for men, your body starts breaking down muscle for energy instead of fat. A 2023 study from multiple nutrition databases found that people on very low calorie diets lost up to 25% of their weight from muscle, not fat.
Here’s how to set your deficit. First, figure out your maintenance calories using an online calculator or by tracking what you eat for a week when your weight stays stable. Then subtract 500 to 1,000 calories from that number.
A 180-pound person typically burns 2,000 to 2,400 calories per day depending on activity. Eating 1,500 to 1,900 calories daily creates the right deficit. Track everything you eat for the first month so you know where you actually stand.
How much protein do you need when losing 50 pounds?
You need 1.6 to 2.2 grams of protein per kilogram of body weight daily to lose fat and keep muscle. For a 200-pound person, that’s 145 to 200 grams of protein every day. A 2024 meta-analysis of 47 studies and 3,218 people found that eating over 1.3 grams per kilogram prevents muscle loss during weight loss.
Protein does three things that help you lose 50 pounds. First, it keeps you full longer than carbs or fats. Studies show that eating 30% of your calories from protein makes people eat 450 fewer calories per day without trying. That adds up to 12 pounds lost in 3 months just from being less hungry.
Second, protein saves your muscle. When you eat less than 1.0 grams per kilogram during weight loss, you lose muscle mass. One study compared people eating 1.0 grams versus 2.3 grams per kilogram. The low protein group lost 3.5 pounds of muscle while the high protein group only lost 0.66 pounds.
Third, protein burns more calories during digestion. Your body uses 20 to 30% of protein calories just to break it down, compared to 5 to 10% for carbs and 0 to 3% for fats. That’s an extra 50 to 75 calories burned per day just from eating protein.
Spread your protein across the day. Eat 30 to 40 grams at breakfast, lunch, and dinner, with snacks filling in the gaps. Studies from the Mayo Clinic show this approach builds and preserves muscle better than eating most protein at one meal.
Does strength training help you lose 50 pounds faster?
Strength training doesn’t make you lose weight faster, but it makes sure you lose fat instead of muscle. A December 2024 study published in Frontiers in Endocrinology found that people who did resistance training gained 1.15 kg of muscle while losing weight. People who only dieted lost muscle.
Here’s what happens when you diet without lifting weights. Research shows that 25% of weight lost comes from muscle, and 75% comes from fat. That means losing 50 pounds costs you 12.5 pounds of muscle if you only cut calories. Your metabolism drops, you look skinny but soft, and the weight comes back easier.
Resistance training flips this. A 2024 study tracking people during weight loss found that 85% of those doing strength training gained muscle while losing fat. None of them lost more than 15% of their weight from muscle. The control group who only dieted? Half of them lost muscle mass.
Lift weights 3 to 4 times per week. Focus on compound movements like squats, deadlifts, bench press, and rows. These exercises work multiple muscle groups and send a strong signal to your body to keep muscle while burning fat.
You don’t need fancy equipment. Bodyweight exercises like pushups, pullups, and squats work fine. Studies show that doing 2 to 3 sets of 8 to 12 reps per exercise builds muscle in beginners. Progressive overload matters more than the specific exercises. Add weight or reps every week.
A 2008 study on women losing weight found that resistance training maintained their resting energy expenditure. The women who only did cardio or didn’t exercise saw their metabolism drop as they lost weight. The strength training group kept burning the same calories at rest.
Should you do cardio or strength training to lose 50 pounds?
Do both, but prioritize strength training. A 2024 meta-analysis found that resistance training preserves muscle and metabolism during weight loss, while cardio alone leads to muscle loss. The best results come from combining 3 to 4 days of strength training with 2 to 3 days of walking or easy cardio.
Walking beats intense cardio for fat loss. You can walk every day without destroying your recovery or appetite. A 150-pound person burns about 100 calories per mile of walking. Walk 5 miles per day and that’s 500 calories burned, creating your deficit without touching food.
High-intensity cardio makes you hungrier. Studies show that hard cardio sessions spike appetite hormones and make people eat more later. Walking or easy bike riding doesn’t trigger the same response. You burn calories without the rebound hunger.
The total weekly target is 150 to 300 minutes of moderate cardio according to general health guidelines. That’s 30 to 60 minutes most days of the week. But you don’t need to do it all at once. Three 10-minute walks work the same as one 30-minute session.
Strength training comes first in your schedule. Lift weights Monday, Wednesday, Friday. Walk or do easy cardio on Tuesday, Thursday, and Saturday. Rest completely on Sunday. This pattern gives your muscles time to recover while keeping your calorie burn high.
What happens to your body when you lose 50 pounds?
Losing 50 pounds reduces your blood pressure by up to 25 mm Hg and doubles your insulin sensitivity. A 2016 study from Washington University School of Medicine found that losing just 5% of body weight improved insulin function, cholesterol levels, and inflammation markers. Losing 50 pounds multiplies these benefits.
Your joints hurt less. Research shows that every pound of excess weight puts 4 pounds of pressure on your knees with each step. Losing 50 pounds removes 200 pounds of pressure from your knees. A study tracking people with knee pain found that losing 10% of body weight reduced pain and improved function significantly.
Your heart works less hard. The American Heart Association reports that losing 10% of body weight improves cholesterol numbers. Specifically, your HDL cholesterol goes up and your LDL cholesterol drops. Your triglycerides also decrease, cutting your risk of heart disease and stroke.
You sleep better. Excess weight contributes to sleep apnea and poor sleep quality. Studies show that losing weight reduces the severity of sleep apnea and helps you fall asleep faster. Better sleep then makes it easier to keep losing weight because sleep deprivation increases hunger hormones.
Your brain works better. A 2013 study in Nutrients found that weight loss improved memory and cognitive function. Brain scans showed increased activity in regions handling memory storage and retrieval. The researchers said obesity-related memory problems are reversible through weight loss.
You might have loose skin. This depends on your age, how long you carried the extra weight, and how much muscle you build. Younger skin with more collagen bounces back better. Losing weight slowly while building muscle helps fill out the space and reduces loose skin.
How do you keep 50 pounds off after losing it?
You keep 50 pounds off by treating maintenance like a continuation of weight loss, not a finish line. Research from the National Weight Control Registry tracking over 10,000 successful people found that 78% eat breakfast daily, 75% weigh themselves weekly, and 62% watch less than 10 hours of TV per week.
The metabolism slowdown is real. When you lose weight, your body needs fewer calories to maintain the new weight. A 200-pound person who drops to 150 pounds needs about 300 fewer calories per day than a person who was always 150 pounds. Studies show this metabolic adaptation lasts for years.
Keep lifting weights. A 2024 study on older adults found that continued resistance training maintains muscle mass and metabolism after weight loss. The group that stopped training regained weight and lost muscle over the next year.
Track your weight weekly. Small weight gains of 5 pounds are easier to fix than waiting until you’ve regained 20 pounds. Research shows that people who weigh themselves regularly catch weight regain early and course correct before it becomes a problem.
Stay active every day. The National Weight Control Registry found that successful maintainers burn about 2,800 calories per week through exercise. That’s 400 calories per day, or about an hour of moderate activity. Walking, cycling, swimming, or any movement counts.
Protein stays high. Keep eating 1.2 to 1.6 grams per kilogram even in maintenance. This preserves muscle and keeps your metabolism running. Studies show that people who drop their protein intake regain weight faster than those who keep it high.
Plan for slips. Everyone overeats sometimes. Research on weight maintenance shows that the difference between people who keep weight off and those who regain it isn’t perfection. It’s getting back on track after a bad day or week instead of quitting completely.
What foods help you lose 50 pounds?
High-protein foods help you lose 50 pounds because they keep you full and preserve muscle. Research shows that eating eggs, chicken breast, fish, Greek yogurt, and cottage cheese at every meal reduces total calorie intake by 400 to 450 calories per day without feeling hungry.
Vegetables fill you up for almost no calories. A cup of broccoli has 30 calories. A cup of spinach has 7 calories. You can eat massive amounts of vegetables and stay in a calorie deficit easily. Studies show that people who eat vegetables at the start of meals eat less overall.
Whole grains beat refined carbs for weight loss. Brown rice, oatmeal, and whole wheat products digest slower and keep blood sugar stable. A 2018 study found that people eating whole grains lost more belly fat than those eating the same calories from white bread and white rice.
Avoid liquid calories. Soda, juice, alcohol, and fancy coffee drinks add hundreds of calories without making you feel full. One study tracked people who cut out sugary drinks and found they lost 5 pounds in 6 months without changing anything else.
The Mediterranean diet shows up in research repeatedly. This eating pattern focuses on fish, vegetables, olive oil, and nuts. A 2023 review found that people following a Mediterranean diet lost weight and had better heart health markers than those on other diets with the same calorie levels.
Portion control matters more than perfect food choices. Using smaller plates and bowls helps. Studies show that people eat 20 to 30% less when they downsize their dishware. Measure your food for the first month so you learn what proper portions actually look like.
Meal prep on Sundays. Cook 3 to 4 pounds of chicken breast, prepare vegetables, and portion everything into containers. Research shows that people who meal prep stick to their diets better and lose more weight than those who wing it every day.
How much does losing 50 pounds cost?
Losing 50 pounds costs between $0 and $3,500 AUD depending on your approach. You can lose weight for free by walking and eating less food, which actually saves money. Or you can spend $2,000 to $3,500 on gym memberships, trainers, and meal plans over the 6 to 12 months it takes.
Walking is free. You don’t need a gym membership to lose 50 pounds. A 2024 review found that people who walked for exercise lost as much weight as those who did expensive gym programs. The difference is consistency, not the price tag.
Eating less costs less. Your food bill drops when you eat smaller portions. Instead of spending money on diet programs or meal replacements, just buy less food. One study found that people saved an average of $50 to $80 per month on groceries when they reduced their calorie intake.
Gym memberships in Australia run $30 to $120 per month. Over 12 months, that’s $360 to $1,440 AUD. You need the gym if you want to lift heavy weights, but bodyweight exercises at home work fine for beginners.
Personal trainers cost $60 to $120 per session in Australia. If you see a trainer twice per week for 6 months, that’s $2,880 to $5,760. Research shows trainers help with form and consistency, but they’re not required to lose weight.
Protein powder costs $40 to $80 per kilogram. One kilogram gives you about 30 servings. This is cheaper than buying extra chicken breast or fish. Studies show that protein powder works the same as food protein for muscle maintenance during weight loss.
FAQ
How fast can you realistically lose 50 pounds? You can realistically lose 50 pounds in 6 to 12 months at a rate of 1 to 2 pounds per week. Studies show this pace preserves muscle and keeps weight off long-term. Faster weight loss leads to muscle loss and weight regain.
Will you have loose skin after losing 50 pounds? You might have loose skin after losing 50 pounds, depending on your age, genetics, and how long you carried the weight. Younger people and those who build muscle during weight loss have less loose skin. Losing weight slowly at 1 to 2 pounds per week helps skin adjust.
Do you need to count calories to lose 50 pounds? You don’t necessarily need to count calories to lose 50 pounds, but research shows that people who track their food lose more weight. You can also lose weight by eating high-protein foods, filling half your plate with vegetables, and avoiding liquid calories without counting.
Can you lose 50 pounds without exercise? You can lose 50 pounds without exercise through calorie restriction alone, but studies show you’ll lose muscle along with fat. Research found that people who only dieted lost 25% of their weight from muscle. Exercise, especially strength training, preserves muscle and metabolism.
How much muscle do you lose when dropping 50 pounds? You lose about 12.5 pounds of muscle when dropping 50 pounds through diet alone, as 25% of weight loss typically comes from muscle. Eating 1.6 to 2.2 grams of protein per kilogram and lifting weights 3 to 4 times per week preserves muscle during weight loss.
What’s the best diet to lose 50 pounds? The best diet to lose 50 pounds is one you can stick to that creates a 500 to 1,000 calorie deficit. Research shows the Mediterranean diet, high-protein diets, and portion-controlled approaches all work. The common factor is eating fewer calories than you burn.
Should you take weight loss medication to lose 50 pounds? Weight loss medications like GLP-1 drugs can help you lose 50 pounds faster, but a 2024 study found they cause muscle loss without strength training and high protein intake. If you use medication, combine it with lifting weights 3 to 5 times per week and eating 1.6 to 2.3 grams of protein per kilogram.
How many calories should you eat to lose 50 pounds? You should eat 500 to 1,000 calories below your maintenance level to lose 50 pounds. For most people, this means 1,500 to 2,000 calories per day. Never drop below 1,200 calories for women or 1,500 for men, as this causes muscle loss and metabolic slowdown.
Does drinking water help you lose 50 pounds? Drinking water helps you lose 50 pounds by replacing high-calorie drinks and slightly boosting metabolism. One study found that drinking 500ml of water increased metabolic rate by 30% for an hour. Water also helps you feel full before meals, reducing calorie intake.
How often should you weigh yourself when losing 50 pounds? You should weigh yourself once per week at the same time of day when losing 50 pounds. Research shows that weekly weigh-ins catch weight stalls early without causing daily fluctuations to mess with your head. Daily weighing works for some people but creates anxiety for others.
