If you need to lose 45 kg, it indicates that your weight and BMI have exceeded healthy limits, and you may be dealing with obesity or at risk of it. Excessive weight puts you at a higher risk of developing diabetes, high blood pressure, or heart disease. To reduce the likelihood of these conditions or to mitigate their effects, the best course of action is to lose weight. However, achieving such a significant weight loss is a challenging process and requires considerable time. With a well-balanced diet and regular exercise, you can bring your weight down to a medically acceptable range and meet your personal goals.
Steps
Create a Plan for Significant Weight Loss

Consult with a Doctor or Registered Dietitian It is important to consult with a doctor to ensure your weight loss plan is safe and suitable for you.
- In addition to seeking advice from a doctor, you should also consult with a registered dietitian. Dietitians and weight loss experts can guide and instruct you on how to lose weight safely and healthily.
- If you need to lose around 45 kg, you might also have chronic conditions associated with being overweight or obese. Therefore, discussing the most appropriate weight loss approach with your doctor is essential.

Set Your Goals. Losing 45 kg is a significant goal, and you will need to stick to a weight loss program for an extended period. Setting realistic goals is a vital step, especially when aiming for such a large weight loss.
- In general, it's safe to aim for a weight loss of 0.5-1 kg per week. Therefore, it could take you a year or more to lose around 45 kg.
- Attempting to lose weight too quickly may not be safe or healthy. Additionally, rapid weight loss is often not sustainable in the long term and may even lead to regaining the weight.
- While long-term weight loss goals are excellent, it's even better to set smaller, incremental goals to keep you motivated. For example, aim to lose 4.5 kg in 4-6 weeks or the first 11 kg within 3 months.

Remove Unhealthy Foods from Your Home. This is perhaps the most effective change you can make immediately to start your weight loss journey. The more tempting foods you have at home, the more likely you are to give in and eat unhealthy items. Transform your home into a healthy environment to support your weight loss goals.
- Eliminate all sweets (like cupcakes or ice cream), chips, cookies, and sugary drinks (such as soda or fruit juices).
- You can also donate unopened food to a local food charity instead of throwing it away.
- The saying "out of sight, out of mind" applies perfectly here. If these unhealthy foods are no longer in your home, you’ll gradually stop craving them and start adjusting to a healthier eating routine.

Plan Your Meals. To kickstart your 45 kg weight loss journey, you need to rethink your meals. Spend a few hours planning your weekly meals to create a framework to follow.
- Consult with a nutritionist to ensure your meal plan is safe and fits your personal health history.
- Start your weight loss journey by planning your meals for the week, including breakfast, lunch, dinner, snacks, and sugar-free beverages.
- If you're following a specific calorie limit, remember to calculate the calories in each meal and snack to ensure you stay within your prescribed calorie range.
- After a few weeks, you might not need to focus so much on your meal plan, especially if you've developed healthy eating habits.
- If you get bored with your meals, review and revise your meal plan. Don’t quit due to boredom. New healthy recipes can spice up your routine and keep you on track with your plan.
Eat to Lose Weight

Cut Calories. To lose weight, you must reduce the number of calories you consume. A moderate-calorie diet will help you reach your weight loss goal.
- Generally, cutting about 500 calories per day can result in a weight loss of 0.5-1 kg per week. This is a safe and healthy rate of weight loss.
- Cutting too many calories or consuming fewer than 1,200 calories per day is unsafe, inappropriate, and unhealthy for the body. A diet with too few calories puts you at risk for nutrient deficiencies because your body struggles to absorb the necessary nutrients when calories are too low. Moreover, such a diet is unsustainable in the long run.
- If you want to calculate how many calories you need to reduce, you can use an online calorie calculator by entering your height, weight, and activity level to determine your optimal calorie intake for weight loss.
- You can also consult with a nutritionist for personalized advice on how many calories to reduce for weight loss while ensuring it is still suitable for your body.

Include Lean Protein in Every Meal. Consuming foods high in lean protein is essential for weight loss. Protein helps keep you satisfied and promotes fat burning.
- Make sure to eat lean protein in every main meal and snack to meet the body’s daily minimum nutritional requirements.
- Generally, women should consume about 46g of protein per day, while men need around 56g of protein daily.
- Some great sources of lean protein include: poultry, lean beef, eggs, pork, seafood, tofu, legumes, and low-fat dairy products.
- Avoid foods that are high in fatty protein, as they contain more calories and can slow down your weight loss process. Examples include fatty cuts of beef, sausages, bacon, full-fat dairy, and chicken skin, which should be consumed only occasionally.

Fruits or Vegetables Should Dominate Your Meals. Fruits and vegetables support weight loss due to their low calorie content, allowing you to eat more and stay full longer.
- Eat a variety of fruits daily or weekly. Aim for about 1-2 servings of fruit per day. One serving is roughly 1/2 cup of sliced fruit, a small piece of fruit, or 1/4 cup of dried fruit.
- Also, try to consume a variety of vegetables daily or weekly. Aim for at least 3-5 servings of vegetables per day. One serving is about 1 cup or 2 cups of leafy greens.
- Starchy vegetables like carrots, peas, or potatoes are also great for weight loss. Although these vegetables are higher in calories, they can still be included in your diet while losing weight.

Choose 100% Whole Grains. It's best to stick with 100% whole grains. Whole grains are rich in fiber, vitamins, and other nutrients.
- Some examples of whole grains include: quinoa, oats, 100% whole wheat bread or pasta, and brown rice.
- One serving of whole grains is about 28g or 1/2 cup. You should aim for 1-2 servings of whole grains per day.
- While whole grains are part of a healthy diet, try to limit their intake during weight loss. They contain more calories and fewer nutrients compared to lean protein, fruits, and vegetables.

Snack Healthily. You may feel hungrier when cutting back on calories and increasing your exercise routine, so healthy snacks can help curb hunger while supporting your weight loss.
- Snack at the right times. For example, when there are more than five hours between meals or before/after workouts to replenish your energy.
- Snacking should follow strict guidelines. If you're not truly hungry or close to mealtime, avoid snacking. Unnecessary calorie intake can slow or hinder your weight loss progress. Be smart about your snacking.
- When losing weight, aim for snacks with around 100-200 calories. Some healthy snacks that promote weight loss include: Greek yogurt, boiled eggs, carrots with hummus, or 1/2 cup of edamame.
- Swap your favorite high-calorie snacks with healthier alternatives. For example, if you crave something sweet after dinner, opt for 1/2 cup of pineapple juice instead of cookies.
Diet Moderately. While dieting requires you to follow a weight loss plan for the long term, it’s also important to treat yourself occasionally. However, you should completely avoid foods that trigger overeating or indulgence.
- Plan occasional treats for yourself. For instance, allow yourself to go out for dinner or have a small sweet treat. Include these rewards in your meal plan to show yourself that you’ve earned it after sticking to the program. You could consider one of the following: either add 10 more minutes to your treadmill workout or reduce your meals for the day.
- Be honest with yourself. Treat yourself only occasionally, not every day.

Stay Hydrated. Proper hydration plays a vital role in weight loss. When you're dehydrated, you might feel hungry and fatigued, which can trigger cravings. However, avoid drinking beverages with added calories, as they can slow down or hinder your weight loss journey.
- Try to drink at least 2 liters of water per day. This is based on general recommendations, but you might need more water depending on your activity level.
- Some calorie-free drinks you can enjoy while losing weight include: water, flavored water, tea, coffee, or sports drinks with no calories.
Exercise for Weight Loss

Consult a Personal Trainer. Getting advice from a personal trainer is a great way to start your exercise program. A fitness expert can guide you through exercises that promote weight loss and help maintain long-term results.
- Discuss your weight loss goals and dietary plans with the trainer so they can assist you in achieving your desired results. If joint pain is an issue due to excess weight, the trainer can also recommend exercises to alleviate discomfort.
- You might also be eligible for free consultations or promotions when signing up for a gym membership.
- Additionally, feel free to switch trainers after a few sessions or once you’ve mastered your exercises. You don’t necessarily need a long-term trainer.

Incorporate Heart-Rate Raising Exercises. Aerobic exercises are excellent for burning calories. Aerobic workouts not only help with weight loss, but they also provide numerous other benefits, such as boosting energy and improving overall fitness.
- Experts recommend combining 150 minutes of moderate-intensity aerobic exercise each week. However, the more you exercise, the more calories you burn, aiding your weight loss efforts.
- If you’re carrying significant excess weight, start your exercise routine gradually. It’s perfectly fine if you can't commit to 150 minutes per week. Begin with just 10 minutes a day.
- Some heart-rate-raising exercises include: brisk walking, cycling, using the elliptical machine, swimming, or water aerobics.

Incorporate Strength Training. Strength training is another type of exercise that supports weight loss. Aim for 1-2 days a week of muscle-strengthening activities.
- Strength training helps build lean muscle mass, which boosts your metabolism and allows you to burn more calories than fat tissue.
- Additionally, it can help you improve your overall body shape by making your muscles more toned.
- Examples of strength training exercises include: weightlifting, yoga, or resistance band training.

Find a Workout You Enjoy. This is crucial because when you like what you're doing, you're more likely to stick with it and exercise more consistently.
- Experiment with different types of workouts. This will help you discover which exercises you can sustain over a longer period of time.
- Be creative with your exercise routine. Consider activities like hiking, dancing, kayaking, or joining a sports team—these are fun and engaging ways to stay fit.
- Change up your workout habits. After a while, your workouts may become routine and boring, so make sure to switch things up to keep them exciting and fresh.
- Find a workout buddy. Having someone to exercise with can boost your motivation and make sticking to your routine easier.
Stay Motivated

Keep a Food Diary. Studies show that tracking your food intake can significantly increase the likelihood of achieving and maintaining your weight loss goals.
- In your food diary, also note your emotions—when you're feeling discouraged or facing challenges that hinder your progress. Writing down positive affirmations or tracking your successes can be a great way to stay motivated and committed to your plan.
- Purchase a food journal, download a tracking app, or find an online food diary to monitor your progress. If journaling daily isn't your thing, you can opt for a few times a week instead.
- Track your meals, progress, measurements, and feelings throughout your weight loss journey.

Find a Support System. Weight loss can be challenging, especially if you have a lot to lose. Achieving a goal like losing 45 kg will take time, and the journey can be long. Having people around to encourage and cheer you on is invaluable.
- Talk to friends or family about your weight loss goals. Ask for their encouragement and support until you reach your target.
- You can also find in-person or online support groups. Being part of a community where others are working toward the same goal can increase motivation and accountability.

Track Your Progress. The more weight you lose, the more motivated you'll be to continue with your plan. But the only way to truly know if you're making progress is by regularly monitoring your weight.
- Weigh yourself once or twice a week. Be sure to weigh in at the same time each week, preferably in the morning before eating.
- Remember that clothes and shoes add weight, so to get the most accurate measurement, weigh yourself with minimal clothing, or wear the same clothes each time you step on the scale.
- Measure your body. Use a tape measure to track your waist, thighs, arms, and neck. As you lose weight and exercise, your body shape will change as well.
Address Weight Loss Plateau

Identify the Causes of Weight Loss Plateau. It's normal for your weight loss to plateau occasionally, especially when you're losing a significant amount. As you lose weight, your body needs to adjust. You may experience a period where your weight doesn't change for a few days or even weeks.
- Monitor your weight loss plateau. This is crucial because if you hit a standstill, you'll need to reassess and modify your diet, exercise routine, and lifestyle to ensure continued progress.
- If you're following your diet and exercise plan but still encounter a plateau, don't stress. Trust yourself and continue with your plan. Remember, reaching a plateau is normal and shouldn't be a surprise. Stay committed and avoid jumping to trendy diets or abandoning your routine.

Review Your Food Diary. Keeping a food diary not only helps you stay on track with your weight loss program but can also aid in identifying why your progress may have stalled.
- Track any extra snacks or indulgent meals. Even if you don't typically indulge or add extra snacks daily, doing so a few times a week can slow or stop your progress.
- Check your portion sizes. Gradually increasing portions can lead to a weight loss plateau.
- While you're focused on losing weight, make sure you're eating enough. Cutting too many calories or portions can slow your progress. A diet too low in calories and nutrients can hinder weight loss and may even backfire.

Change Your Habits. If you're experiencing a weight loss plateau, try switching up your workout routine to jump-start your weight loss again.
- Try different heart-rate boosting exercises like HIIT or circuit training (a series of continuous exercises with no rest in between, sometimes using weights or equipment) to burn more calories. You can also add or focus on strength training to boost your metabolism.
Tips
- Develop the habit of brushing your teeth between meals. A fresh mouth can reduce the temptation to snack.
- While exercise is beneficial for weight loss, it alone won't be enough to shed pounds. Remember, your diet contributes 70% to weight loss, while exercise contributes 30%.
- Everyone slips up on their diet at some point, but don't let it derail your progress. Don’t give up just because you've had a day or week of unhealthy eating. Learn from your mistakes and get back to your healthy eating plan.
- It may be more effective to share your weight loss goals with friends and family. This way, they can offer support and won’t tempt you with unhealthy food.
- Whenever possible, cook at home. While dining out may be enjoyable, finding healthy diet-friendly options is rare. If you must eat out, try to reduce calories by using less sauce and avoiding fried foods.
- Control cravings by drinking plenty of water and other unsweetened beverages between meals. Chewing sugar-free gum can also keep your mouth busy and create the sensation of snacking.
