What Is Healthy Eating?

Eating a variety of foods together in adequate portions will provide you with complex carbohydrates, fibre, protein, and a bit of fat, which, when combined, fill you up for hours and provide tons of nutrients and health benefits.

What Does Being Underweight Mean?

​​Being underweight is defined as having a body mass index (BMI) below 18.5. This is estimated to be less than the body mass needed to sustain optimal health.
What many people don’t realise is that gaining weight can be just as challenging as losing weight. While the main focus is to increase energy and protein intake, it is also important to maintain a healthy balanced diet without eating too many foods that might have high amounts of calories but little in the way of good nutrition. 

How To Include Food To Gain Weight?

If you’re underweight, you want to gain a balanced amount of muscle mass and subcutaneous fat rather than a lot of unhealthy belly fat. The most important thing you can do to gain weight is to create a calorie surplus, meaning you eat more calories than your body needs.

Do You Have To Count Calories?

You don’t need to count calories for the rest of your life, but it helps to do it for the first few days or weeks to get a feel for how many calories you’re eating. To find out your own caloric needs for weight gain, you'll first need to get an idea of your resting metabolic rate (RMR). This is the number of calories your body needs to support a sedentary lifestyle, not including exercise. Once you've established your RMR, you can factor in your activity level for a more accurate calculation of your needs.

Are Eggs Good For Weight Gain?

Eggs are, overall, one of the best health foods that encourage muscle development, as they are packed with high-quality proteins and healthy fats.

List Of Healthy Foods To Gain Weight

Eating breakfast is important, but what you eat for your meals matters too. Everyone's individual caloric needs are different, so talk to a dietitian to determine what's right for your body, activity level, and goals. Here are ten healthy food options for weight gain. Have a look!


Unlike popular opinion, milk is not the worst. In fact, studies have shown that people tend to gain muscle mass when they drink milk in combination with weight training. It’s beneficial for muscle growth as it contains the perfect balance of nutrition to support muscle growth and replenish depleted glycogen stores after intense exercise.


If you’re looking to gain weight, rice is probably your best friend. Convenient and a low-cost carb, it can obtain a high amount of carbs and calories from a single serving. Have it with your favourite dal or mix it with mangoes for a sticky rice dish. You can also stir it up with finely chopped veggies like carrots, onions and cabbage to get your take on the dish of fried rice. 

Peanut Butter

All nuts and nut butter are the perfect choices to gain weight. Since nuts are very calorie-dense, just two handfuls per day with a meal or as a snack can quickly add hundreds of calories. You can add nut butter to a variety of snacks or dishes, such as smoothies, yoghurts, and crackers, to turn them into a high-calorie snack in no time.

Red Meat

Meats that are red when raw are defined as red meats. This includes lamb, beef, pork and some others. Pick your choice according to what’s available easily and go from there. Steak contains both leucine and creatine, nutrients that play a significant role in boosting muscle mass. Steak and other red meats contain both protein and fat, which promote weight gain.

Dried Fruits

Dried fruits are rich in nutrients and calories. You can get many different types of dried fruit, and they all have naturally high sugar content. This makes them great for gaining weight, especially since they’re convenient to eat and taste great. From dates and raisins to almonds and walnuts, the choices in the market are endless.


Yes, you heard it right! Avocados are not just about Instagram shots but are a great choice for you to gain weight.  Full of healthy fats and nutrients, avocados are also high in vitamins, minerals, and various beneficial plant compounds. One of the most popular and easiest ways of enjoying avocado is on avocado toast. Just mash up some avocado and spread it on your toast. Squeeze a bit of lemon and there you have it!

Dark Chocolate

Keeping even the dementors away, dark chocolate helps reduce the risk of heart disease, some cancers, inflammation, stress, and type 2 diabetes while keeping your spirits up. Garnish your morning cereal with it, put a few curls on top of a fruit plate, or make some steaming-hot drinking (or sipping) chocolate as the Parisians do.

Full Fat Yogurt

Full-fat Greek yoghurt is another healthy and convenient snack. It has a great nutritional profile, including a well-balanced mix of protein, carbs, and fat. It’s great on its own or as an ingredient that works in many dishes. Want to make it a little more healthy? Add in some flax seeds and your favourite sweet fruits. Seasonal ones are the best!


With so many ways of cooking and serving it, here’s your chance to get creative. Pasta can provide a calorically dense and carbohydrate-rich path to healthy weight gain. Avoid bleached pasta, and opt for those made with whole grains. From spaghetti to penne, you can go in any direction here. But make sure to add a few green veggies like broccoli or spinach on a side for a healthier diet.

Starch Rich Foods

Starches help some of the foods already listed to boost muscle growth and weight gain. They add bulk to meals and boost the number of calories consumed. Not only do potatoes and other starches add carbs and calories to help you gain weight but they also increase your muscle glycogen stores. Glycogen is the predominant fuel source for most sports and activities.

Diet Plan For Weight Gain - 7 Day Chart

Have already made notes to kickstart the new week with a healthy diet plan? We have jotted down a one-week weight gain diet. A great way to use up all the food listed above. Check it out!

Day 1

Keep your breakfast light but surely tasty with a big bowl of oats, chia seeds, full cream milk and some fruits. Always go for seasonal ones but you can also opt for some dried fruits as well. For lunch opt for a creamy cottage cheese curry with some whole wheat chapatis. Snacking can include a glass of milk, a handful of mixed dried fruits and an apple. To end the day, go for spaghetti cooked in fresh tomato puree with a side of broccoli or spinach.

Day 2

Mix your love for peanut butter and toast for breakfast on day two. Drizzle a bit of chocolate syrup or honey according to your taste. Add in a glass of milk or coffee, fruit and there you go. Opt for an egg salad for lunch. Two or three hard-boiled eggs, chopped onions, tomatoes, garlic, lettuce, cucumber, carrots and avocados, grated cheese and salt to taste. You can also add some coriander and lemon juice for some freshness.

Evening snacks can include your staple protein shake and a small mango. Finish the day right with the porridge of your choice but don’t forget to include as many veggies in it as you can. You can also include a bowl of full-fat yoghurt to complement the porridge. 

Day 3

Wednesday! It's egg day! Scrambled or sunny-side up or a rich omelette, have your favourite kind of eggs. Serve a mug of hot chocolate or coffee made with full cream milk. For lunch, go for a South Indian meal. Idli and sambar with chutney is the way to go in the afternoons. Don’t forget to have a cup of rasam too.

As the evening is approaching, feeling hungry again? Make sure that you do not go for cheese and crackers to satisfy your salty cravings. However, if you are more of a sweet-kinda person, a fruit smoothie is the solution.

For dinner, have salmon or any other oily fish of your choice. Oven-baked salmon fillet, sprinkled with sesame oil and sesame seeds + wholemeal couscous + 2 cups cooked vegetables. Serve with hummus. It’ll be mouth-watering, we promise!

Day 4

Good job! You’re halfway there! Time to celebrate that with an Instagrammable breakfast. Go for poached eggs on toast with a side of sauteed veggies. And your staple protein shake. For lunch, go for good old fish and chips. Finish the meal with mashed potatoes and lemon wedges.

Since your first half of the day has been protein-rich, keep your snacks simple with cucumber slices. Easy to nibble on the go, you can also add chaat masala to make it a bit more fun.

For dinner, go for mango chicken and corn. Grilled chicken thighs served with mango salsa, corn on the cob & 1.5 cups baked vegetables (eg. carrot, onion, beans) in olive oil. End the day with seasonal fruit for dessert.

Day 5

Day 5, assuming it’s Friday, it surely should be “Friyay”. Go for bread and jam sandwiches, a bowl of assorted berries and your favourite beverage made with whole fat milk. Have potato and quinoa salad for lunch. Add vegetables like cucumbers, tomatoes and as many leafy greens as possible.

Remember when we talked about how dark chocolate is healthy? Well, it’s time to include it in your diet today. To celebrate the weekend mood if not anything else. Accompany it with some prunes, they go well together. At last, it is the return of pasta (though preferably cooked in another way). Go for spinach ravioli for a healthy alternative or try out new cuisine. We recommend Tibetan Thukpa or Thenthuk. Both being soupy and yummy.

Day 6

Finally, the weekend is here and you’re so close to finishing your diet plan to gain weight. Here’s a recipe for Strawberry oats!
Strawberry And Yogurt Oats.

Remember sipping strawberry milkshakes through bendy straws on hot summer childhood days? Well, this recipe is for all you people out there who still enjoy strawberry flavoured food. And if there’s a way to make it healthy? There should be nothing stopping you.

  • What do you need? A handful of strawberries, greek yoghurt, oats, honey or sugar-free maple syrup and milk. You can also use flavoured protein powder with it.
  • Half cups of milk, oats and yoghurt each should work.
  • Mix all the ingredients (except strawberries) in a jar or a bowl before going to bed.
  • Leave it in the refrigerator overnight. This will give your oats a naturally creamy texture.
  • In the morning, top the oats with sliced strawberries and a drizzle of honey or maple syrup and enjoy your healthy breakfast.
  • You can also replace strawberries with bananas.

For lunch, the perfect choice is a British dish, called bubble and squeak. The idea is to get the best of your weekly leftovers, potatoes, cabbage, meat (if you have it) and pan-fry it. It’s filling and tastes good too. Snack on carrots and hummus on day six.

End the day with one pot of creamy chicken and mushroom pasta. You can surely add more vegetables if you like. Pair it with your favourite wine.

Day 7

Chill on day seven by having your breakfast, either in bed or on the go. Any guesses?

A granola bar and a mug of coffee made with full cream milk. Include red meat with a bowl of well dressed green salad for lunch. Olive oil works pretty much with all kinds of salads. Catch a movie on your favourite streaming platform and enjoy the weekend with a big bowl of popcorn. Salted, butter, caramel? Your pick! End the day, week and the weekly diet plan with your favourite street food. Hard workers deserve a cheat meal, don’t they?
That concludes your week of a balanced, nourishing diet plan for a healthier body mass!
