Losing 20 pounds (lb) can have significant health benefits for people who are overweight or have obesity.

Losing even 5 percent of your body weight can improve cholesterol, blood glucose, and blood sugar levels in people who don’t have a healthy body weight.

Safe, sustainable weight loss can reduce your risk of chronic conditions like type 2 diabetes, reduce stress on your joints,

 and potentially improve sleep apnea.

Rapid weight loss is not always the best option. Crash diets often fail because their extreme measures are not sustainable.

You can achieve steady weight loss through new approaches to sleep, stress management, exercise routines, and diet, resulting in measurable outcomes with a higher likelihood of success.

Healthcare professionals recommend losing no more than 1 to 2 lb per week.

 While 20 lb in about 10 weeks hits the upper end of this limit, it is potentially achievable by taking the right approach.

How Large a Calorie Deficit Would You Need?

In the most basic terms, a calorie deficit means consuming fewer calories from foods and drinks than your body uses in a day.

A consistent calorie deficit of about 500 to 750 calories each day can result in weight loss of around 1.5 lb per week. This means a daily deficit of 1,000 calories would lead to burning roughly 2 lb per week.

Maintaining this for 10 weeks, although challenging, could result in losing 20 lb.

However, to prevent malnutrition and other adverse effects, females should not consume fewer than 1,200 calories per day, and males should not consume fewer than 1,500 calories per day.

Weight loss is a highly individual process, too. Factors including stress, medications, underlying conditions, hormones, environmental factors, and genetics all play a role in how quickly you lose weight in a deficit.

Tracking calories may help you maintain control of this deficit. However, some people don’t feel comfortable tracking calories and instead choose to moderate intake in other ways, such as through eating only low-calorie meals or eating only during specific time frames, known as intermittent fasting.

What Diet Changes Can Help You Lose 20 Pounds in 10 Weeks?

Diet changes may be necessary to support a reduced calorie intake. Though many people choose to make these changes without assistance, you may want to consult a healthcare professional or dietitian before making significant changes to your diet and for support in monitoring ongoing changes.

This is vital if you live with diabetes or other health conditions that your diet may affect.

Making note of what you eat and creating meal plans ahead of time can also help you reach your weight loss goals. When creating a meal plan, make sure the adjustments are both healthy and sustainable for you. Otherwise, you may find that you regain weight or stop making any progress on weight loss.

Focus on a diet that includes plenty of fruits and vegetables, whole grains, and healthy fats, like olive oil or oily fish.

 Avoid foods that are high in salt, saturated and trans fats, or have added sugars.

 And make sure to include high-protein foods like beans, pulses, fish, eggs, or lean meats that help you feel fuller.

If you find that you feel hungry when you cut calories, try changing the type of foods you eat. Here are some substitutions to consider that can help you feel fuller:

  • Broth-based soups instead of cream-based soups
  • Carrot and celery sticks with hummus instead of pretzels, chips, or crackers
  • Extra-lean ground beef instead of regular ground beef
  • Low-fat dairy instead of regular-fat dairy
  • Steamed vegetables instead of fried vegetables or french fries

Exercising for Weight Loss: More Than Just Calories

Burning calories with exercise is a crucial component of any weight loss plan. According to one review, 150 minutes of moderate- to high-intensity exercise each week can support fat loss for all adults who are overweight or have obesity.

More exercise may be necessary for some people to lose weight and maintain a healthy body weight.

 Ultimately, more movement and activity mean more calories burned, which increases the deficit and may help you get closer to your goal of losing 20 lb in 10 weeks.

When choosing cardio workouts or activities, make sure you choose something you enjoy enough to stick with it. You’ll also want to mix up your activities to keep them fun and engaging as well as to work out different muscles and joints.

Remember to be patient with yourself, and listen to your body. It’s okay to take a couple of days off if you don’t feel good.

The following activities and exercises can support a weight loss journey:

  • Walking
  • Hiking
  • Running or jogging
  • Gardening
  • Yard work
  • Group fitness classes
  • Swimming laps in a pool
  • Water aerobics
  • Using exercise equipment like ellipticals, rowers, stationary bikes, or treadmills
  • Playing a team sport
Including muscle-strengthening workouts, like lifting weights, is also essential for both general health and weight loss. Try to target all of your major muscle groups at least twice per week.

 This ensures that you build and maintain your lean muscle mass while burning fat.

Lifting weights is an excellent way to strengthen muscles if you have a gym membership or access to dumbbells or kettlebells at home. But you can still practice strength training with other equipment, such as resistance bands, or body weight exercises like push-ups, sit-ups, and squats.

Aim for a minimum of one set of 12 to 15 repetitions per exercise. Increase the weight or resistance as this starts to get easier over time to make sure you continue to challenge yourself. You can gradually increase the number of reps or sets as you feel your strength growing.

Whether you’re doing strength training or cardio, be sure to warm up before exercising and cool down at the end of your workout. This helps decrease the risk of injuries that may derail your exercise and weight loss plan.

If you’re brand new to exercise, you may want to talk to a doctor or personal trainer before getting started. A doctor can give you a safe starting point. A trainer can support you by creating an individualized routine, guiding you through the correct form for each exercise, and keeping you accountable.

Other Lifestyle Measures to Support Losing 20 Pounds in 10 Weeks

Sustained and steady weight loss goes beyond exercise and diet changes. Other factors can influence weight management beyond your initial goal.

Before starting, consider other factors and measures that may improve your chances of achieving healthy weight loss:

  • Assess your readiness to make the necessary changes, including whether you are prepared to commit. Discuss your goals with a doctor. Consider stress eating and stress management strategies, and identify other barriers that might prevent you from reaching your goals.
  • Set reasonable goals for your weight loss and track your progress against them, especially if you’re aiming for 2 lb per week, which is at the more ambitious end of the safe weight loss range.
  • Discover your inner drive to stay motivated, including your personal whys. Surrounding yourself with people who can support your goals, such as a fitness group, a weight loss group, or supportive friends and family, can help you stay driven and accountable.
  • Discover how to make healthy foods taste great with a variety of spices, herbs, and aromatic veggies. Explore other cooking techniques.

Thinking about other goals may help if you don’t quite hit your weight loss targets. While it may have health benefits, 20 lb in 10 weeks is simply a number (and a high one at that). Your motivation may benefit from considering your deeper drive for weight loss.

Do you want to live longer? Feel better? Have more energy for your kids or grandkids? Thinking beyond weight loss can help you stay motivated and committed as well as help prevent negative self-talk if you don’t reach your exact numerical goal. Psychology and successful diet management may have close links.

Hormones, stress, and sleep can all influence weight changes, too. According to a study on sleep and weight loss, disturbed sleep, characterized by poor quality and insufficient duration, can lead to weight gain, often through snacking on high-fat or high-carb foods.

Stress management can also play a role in weight loss. Cortisol is a hormone that circulates in response to stress. High levels may lead to the development of abdominal fat, increase cravings for snacks high in sugar, calories, and fat, and cause you to feel hungrier.

If you can, try to identify what causes you stress and find ways to manage your response to them, such as meditation. Getting adequate sleep and exercise may help. But if stress becomes overwhelming, you may benefit from speaking to a mental health professional, such as a counselor.

Accounting for more than just dieting and exercise may help you maintain your efforts past your initial weight loss goals and live a healthier, more active life.

The Takeaway

  • Losing 20 lb in about 10 weeks is challenging but possible. You’ll need to maintain a calorie deficit of 750 to 1,000 calories per day to lose 2 lb weekly.
  • Achieving this goal requires a combination of healthier eating, increasing exercise, and managing other areas of your life, such as stress and sleep.
  • Setting realistic goals, tracking food intake, and working with others can all help you achieve your initial goals and continue making healthy choices after you reach your goal weight.
  • Speak to a healthcare professional, nutrition expert, or personal trainer if you’re finding weight loss challenging or feel you’d benefit from support.
