Eleven amazing foods for the 7-day weight gain diet

An ideal diet for weight gain must provide you with essential nutrients. It is imperative to not just be fixed on food calories, but also on the nutritional benefits that they can provide. Here, we have compiled amazing foods to consume for the 7-day weight gain diet

1. Milk

Milk is a great source of diverse minerals and vitamins like calcium, protein, vitamins, and D. It also offers a combination of carbohydrates, fats, and proteins. The major type of proteins in it are casein and whey, which are known to aid the reduction of cholesterol levels and blood pressure. These proteins can also contribute to the development of lean muscle. Milk is excellent for anybody looking to gain weight, especially the type of milk that contains generous amounts of fats because it can offer you more calories. A study showed that women who drank skim milk after participating in resistance training, built muscles more effectively than other women who took soy milk. Drinking milk can also aid the prevention of bone fractures and osteoporosis. However, if milk upsets your body system, it is not a great choice to add to your 7-days weight gain diet. 

2. Nuts and nut butter

These are perfect choices for your 7-day weight gain diet, as they have lots of calories. For example, ¼ cup serving of raw almonds contains up to 170 calories with six grams of protein, 15 grams of healthy fats, and about 4 grams of fiber. Nut butter is calorie-dense too and can be added to different dishes or snacks. In addition, only purchase nut butter that does not contain extra oils and sugar. Other nuts that contain high calories include pistachios, cashews, walnuts, and Brazil nuts.

3. Homemade smoothies

Homemade protein smoothies are a fast way to gain weight. As most commercial versions of protein smoothies are loaded with sugar and lack enough nutrients, the best method is to make them yourself. Another advantage of making them at home is that it gives you full control over the nutrition content and flavor. For the 7 days weight gain diet, you can make smoothies like vanilla berry shake, caramel apple shake, super green shake, chocolate hazelnut shake, strawberry peanut butter banana smoothie, strawberry avocado smoothie, and blueberry avocado smoothie. 

4. Oily fish 

Oily fish are great sources of amazing nutrients like protein and omega-3 fatty acids that can give the body protection against certain diseases. Consuming oily fish can reduce the risk of arthritis, cancer, and heart disease. Salmon contains up to 250 calories and 12 grams of good fats that can accelerate your weight gain. Other types of oily fish that you can add to your diet include kippers, mackerel, herring, eels, sardines, pilchards, and trout.

5. Red meats 

Red meat is ideal for muscle building, as it contains a powerful amino acid called leucine. Leucine is important in triggering the protein synthesis of muscles and developing new muscle tissues. In addition, red meat contains about 456 calories and almost 49 grams of protein. For this diet, consider going for fattier cuts than lean meats to help you gain weight quickly. One of the best parts of beef that are fatty is brisket. It contains up to 300 calories per 85 gram serving. 

6. Starchy foods 

Starchy foods like potatoes are perfect for a weight-gain diet. They are cost-effective and can be consumed to enhance the growth of the muscles. Starchy foods are great for the 7 days weight gain diet because they can boost your calorie intake. Starches are also a great source of carbs that have diverse benefits such as energy provision and improved gut health. Excellent options to add to your diet include quinoa, rice, pasta, peas, lentils, and dried beans. 

7. Dried fruits 

While most people think that fruits do not retain a great percentage of their nutrients when dried, this is not true. Dried fruits retain most of their minerals and vitamins and are rich in antioxidants. During the 7-day weight gain diet, it is necessary to eat healthy snacks and dried fruits are a great option. In addition, you can combine dried fruits with proteins like cheese, meat, or protein shakes. Apricots, currants, raisins, dates, prunes, and figs are some of the dried fruits to consume on the one-week weight-gain diet. 

8. Cereal bars

Cereal bars are also healthy snacks for this diet. They are also ideal to consume before or after a fitness session because they are a combination of both fast and slow-digesting carbohydrates. You can enjoy them with other protein foods like boiled Greek yogurt, eggs, and protein smoothies. However, ensure you add only cereal bars that do not contain preservatives and extra sugar to your diet. 

9. Whole eggs 

If you are utilizing this diet to build muscles, you must consume eggs. They contain a mix of powerful proteins and fats. A large raw egg has about seventy-four calories. Enjoy the versatility of eggs by frying, poaching, baking, scrambling, or boiling them. In addition, use eggs in muffins, desserts, casseroles, and salads.

Increase your intake of energy-dense foods

It’s very important to eat mostly whole foods, like fruits, vegetables, whole grains, and legumes.

Also, try to emphasize energy-dense foods as much as possible. These are foods that contain many calories relative to their weight.

Here are some energy-dense foods that may help you gain weight:

  • Nuts like almonds, walnuts, macadamia nuts, and peanuts
  • Dried fruit, including raisins, dates, prunes, and others
  • High fat dairy, such as whole milk, full-fat yogurt, cheese, and cream
  • Fats and oils like extra virgin olive oil and avocado oil
  • Grains, including whole grains like oats and brown rice
  • Meat, such as chicken, beef, pork, and lamb; you can also choose fattier cuts
  • Tubers, including potatoes, sweet potatoes, and yams
  • Other energy-dense foods like dark chocolate, avocados, peanut butter, coconut milk, granola, and trail mix

It may be a good idea to avoid over-consuming vegetables and fruit if gaining weight is a priority for you. The fiber in fruits and vegetables can lead you to feeling full faster. This can leave less room for energy-dense foods.


Base your diet on energy-dense foods as much as possible, as they contain many calories relative to their weight without processed sugars or unnatural ingredients.
