To achieve the goal of gaining weight while building muscle, you may need to adjust both your diet and exercise routine. Knowing how to choose nutritious foods and exercise correctly can help you gain weight safely and develop more muscle. Clearly, no one wants to gain weight in an unhealthy way or consume unhealthy foods to aid in weight gain. Therefore, it's important to balance calorie intake and physical activity to ensure safe weight gain while building muscle.
Steps
Set Goals

Consult with a Doctor. Before starting a new workout regimen or making significant changes to your diet, it’s essential to consult your doctor about your individual health situation.
- Let your doctor know why you want to gain weight and build muscle, and discuss any lifestyle changes you want to make.
- Ask your doctor what a safe weight gain goal is for your age and gender. Gaining too much weight could potentially lead to being overweight.

Set realistic goals. Every individual’s body is different. Think and set realistic long-term goals for yourself.
- Your goals should be specific and measurable. Avoid setting vague goals like "gain weight" or "build muscle." Aim to set clear, detailed goals. If your goal is too ambiguous or overly ambitious, it will be hard to achieve.
- At the same time, set a timeline for reaching your long-term goals. For example, I want to gain 10 kg in 3 months.
- Once you've set your long-term goals, break them down into short-term objectives. Setting weekly goals will help you stay on track.

Track your progress. Whenever you set a goal, you must track your progress. This will motivate you to stay focused and allow you to see the results of your efforts.
- Track various measurements. You can monitor your weight, body fat percentage, or body measurements.
- Tracking your progress helps evaluate whether your diet and exercise plan are effective. For example, if you're not hitting your weight goals, you might need to adjust your calorie intake or calorie expenditure through exercise. You should reassess or take measurements every two weeks for an accurate view of your program's effectiveness.

Find a workout buddy. Find someone to share your plan with. Adopting this lifestyle change can be challenging, so having someone to talk to can help provide motivation and persistence in sticking to your plan.
- Inform friends, family, trainers, nutritionists, or colleagues about your goals so they can help you track your progress weekly.
- Take responsibility. It's up to you to make adjustments as needed. While a workout buddy can assist, you play the most crucial role in the process.
Eat to Gain Weight and Build Muscle

Consult with a nutritionist. A nutritionist will guide you on the appropriate diet and food choices to help you build muscle and gain weight.
- Consult a doctor or find a local nutritionist. There are many experts in weight gain and/or sports nutrition.
- Discuss your goals with the nutritionist so they can provide a tailored plan. You can ask them about meal plans, cooking tips, and advice on the total calorie intake you should aim for.

Increase your daily calorie intake. In order to gain weight, you must raise your overall calorie intake. Try increasing your daily calories by 250-500 to help with weight gain. With this amount, you can expect to gain around 0.2-0.5 kg per week.
- If your weight increases faster than this, or if you're relying on unhealthy foods to gain weight, these are considered improper ways to gain weight.

Choose high-calorie foods. Increasing your daily calorie intake can be a challenge because it requires eating more and selecting calorie-rich foods. If you find it hard to meet your calorie goal, consider adding more healthy, calorie-dense foods to your meals.
- Try consuming: high-fat dairy products, olive oil, butter, nuts, and peanut butter.
- Add olive oil or a thin slice of butter to your meals after cooking. You can also add butter to salads or eat it with eggs in the morning. Mix peanut butter into your protein shakes or use it as a snack in the afternoon.
- Avoid sugary snacks to boost your calorie intake. While cookies, candy, and donuts may help with weight gain, they aren't healthy methods for doing so.

Consume enough protein. If your goal is to gain weight and build muscle, it's essential to consume adequate protein. Lean proteins (along with vegetables) should form the core of your daily diet.
- Experts recommend consuming 0.8g of protein per kilogram of body weight.
- However, some studies suggest this amount might not be sufficient, especially if your goal is building lean muscle. In this case, you can aim for 1g of protein per kilogram of body weight, but avoid exceeding this amount.
- A typical protein serving is about 74-112g. To meet your minimum goal, make sure each meal and snack includes a serving of lean protein, which might allow you to consume a bit more than your minimum target.
- Focus on both lean proteins and moderate-fat proteins. Try including foods like poultry, eggs, low-fat or full-fat dairy, lean beef, pork, seafood, or legumes.
- Avoid high-fat, fried, or processed protein sources. Foods like fried items, processed meats, or fast food aren't healthy and should be avoided for weight gain.

Consume healthy carbohydrates before and after your workouts. Studies suggest that consuming complex carbohydrates after exercise can reduce muscle breakdown and promote muscle growth in the long term.
- Eat a carb-rich snack about 30-60 minutes before your workout. This provides sufficient energy to your muscles during the workout and helps with recovery afterward.
- Post-workout carb-rich foods include: fruits, mashed potatoes, whole-grain bread, dried fruits, or yogurt.
- Also, make sure to include healthy carbs in your main meals and snacks. Whole grains, fruits, beans, and starchy vegetables are excellent sources of necessary nutrients. These foods should be included in your daily diet.

Eat fruits and vegetables. While it's important to focus on high-protein and calorie-dense foods to reach your goals, don't forget to consume enough fruits and vegetables each day.
- Aim for 5-9 servings of fruits and vegetables per day. Include some in each of your meals or snacks.
- A serving of fruit is typically 1/2 cup of chopped fruit or one small piece. A serving of vegetables is 1 cup, or 2 cups of leafy greens.

Consider using protein supplements. You can incorporate protein shakes into your daily routine to help meet your daily protein goals and accelerate muscle growth.
- You can drink a protein shake at any time of the day. However, many studies suggest that consuming 20g of protein shake before strength training can enhance protein synthesis.
- You can also use protein drinks to boost your overall calorie intake. Try mixing protein with high-fat milk, adding fruits, peanut butter, or even avocado to increase your calorie consumption.

Keep a food diary. Keeping track of what you eat can be helpful when you're trying to gain weight. A food diary will help you understand exactly what you're eating and how it impacts your weight.
- Be honest about your food intake and record it. Invest in a food scale and measuring cups to ensure accuracy. These tools can help you monitor your portion sizes.
- At first, you may struggle to reach your target, especially if you're making significant changes. Consider using a food journal or buying a dedicated notebook to track your eating habits.
- If you're not gaining weight, or if you're losing or gaining weight too quickly, review your food journal. If necessary, adjust your meal plan.
Exercise to promote weight gain and muscle growth.

Find a trainer. With your doctor's approval, consider hiring a personal trainer. A trainer can guide you through exercises tailored to help you reach your weight and body composition goals.
- With their knowledge, qualifications, and experience, fitness experts can assist you in achieving your workout objectives.
- Discuss your goals with the trainer and ask for their assistance in muscle-building exercises. You can even ask them to help create a weekly workout schedule for you.
- You can find a trainer at your local gym or seek out a personal trainer for consultations outside the gym.

Train by targeting specific muscle groups. To increase muscle mass, you need to train individual muscle groups.
- It’s important to work on all muscle groups, including your core, lower body, upper body, arms, and chest.
- You can structure your training over three to four days, focusing on one muscle group each day. Ideally, you should alternate workout days with rest days.
- You can also opt for daily strength training if you prefer to target different muscle groups on separate days throughout the week. Just be sure not to work on the same muscle group on consecutive days.

Rest days are essential. Although consistent exercise is crucial for building muscle mass, taking 1-2 rest days each week is equally important.
- The majority of muscle growth actually happens during the rest periods between workouts.
- If you prefer more frequent rest, avoid training the same muscle group on consecutive days. For example, don’t train your arms and chest on both Monday and Tuesday. Instead, try working on arms and chest on Monday and then focus on legs the following day.

Monitor your workout progress. Using a training log to track your exercises can provide additional motivation and help you stay organized with your weekly routine.
- Tracking your progress ensures you're gaining strength throughout your workouts. Additionally, a training log helps you keep track of what you’ve done on which day, which is key to planning your rest days.
- Besides tracking your daily or weekly progress, also note how long you’ve been working out and how much longer it will take to achieve your long-term goals.
Incorporate specific exercises to enhance muscle growth.

Use weights to target your core. Some studies suggest that lifting heavy weights during core exercises can maximize muscle growth and define your midsection.
- Your abs are engaged during most daily activities, so it’s important to increase the weight in your core exercises to stimulate muscle development.
- There’s no strict rule for how many core exercises you should do or whether you should train more or fewer reps. However, it’s best to continue training until your muscles are fatigued.
- Make sure to perform the movements slowly and with control when targeting your abs.
- And remember to breathe evenly!

Work on your upper body too. To build muscle in your upper body, include a variety of exercises targeting your chest and arms. For this type of training, use heavier weights and fewer reps:
- Overhead press
- Incline bench press
- Dips and pull-ups
- Bicep curls

Focus on exercises for your lower body. To build muscle mass in your lower body, it’s best to start with individual exercises before progressing to more intense strength training routines. Combine these exercises with heavy weights and moderate intensity:
- Seated leg curl
- Leg extension
- Lunges
- Dumbbell Step-Up
- Barbell squat

Start slow. Whenever you begin a new workout or strength training plan, it’s essential to start slowly.
- Even if you're encouraged to use heavy weights at the start, it’s better to choose lighter weights to match your fitness level and goals.
- In the beginning, you might need more rest days to give your muscles the time they need to recover properly.
- Plan your training over two weeks, gradually increasing the weight as you progress. After this phase, you’ll need to use heavier weights to build muscle mass and strength. You may extend your rest periods, but it's crucial to start lifting heavier weights to achieve lean muscle growth.
