These Foods Could Make You Gain Weight in Just One Week – Expert Explains

Many people think gaining weight quickly means piling on junk food or eating as much cake as possible. But that myth overlooks something important: gaining weight healthily requires choosing the right foods, not just more of them. 

To help clear things up, we spoke with Dr Anshu Chaturvedi, Head of the Department of Dietetics at CK Birla Hospitals, Jaipur, who explains what foods really help you gain weight in a balanced way and which ones to skip if you want healthy progress.

Why Nutrient-Dense Food Matters for Weight Gain

Dr Chaturvedi explains that gaining weight should not mean eating unhealthy foods. It’s about choosing nutrient-dense options that support overall health and muscle growth, not just adding empty calories. Healthy weight gain can improve energy levels, strengthen the immune system, and promote a better body composition.

Top Foods to Help You Gain Weight in a Week

Here are some of the best foods Dr Chaturvedi recommends for effective, healthy weight gain:

• Nuts and Nut Butters: Almonds, walnuts, cashews, and peanut butter are calorie-rich and packed with healthy fats and proteins. “Just a handful of nuts or two tablespoons of nut butter daily can make a noticeable difference,” she says.
• Milk and Dairy: Whole milk, cheese, paneer, and yogurt provide essential fats, proteins, and calcium. Dr Chaturvedi suggests, “Adding a glass of milk or smoothies made with yogurt and fruits can boost your calorie intake deliciously.”
• Starchy Foods: Potatoes, sweet potatoes, rice, oats, and whole grains supply energy and aid muscle buildup. “Combine them with healthy fats like olive oil or ghee for extra calories,” she notes.
• Healthy Fats: Incorporate foods like avocados, coconut, and olive oil into your meals. “These fats are essential—they help increase overall calorie consumption and support cell health.”
• Protein-Rich Choices: Eggs, lentils, beans, tofu, and lean meats are vital for muscle repair and growth. “Adding protein to every meal supports healthy weight gain without excessive fat.”
• Smoothies & Dark Shakes: Homemade high-calorie drinks with milk, bananas, nuts, and oats are tasty and quick ways to boost energy and calories.

Tips to Gain Weight Fast and Healthy

Eat five to six small meals rather than three large ones, to maximize calorie intake.

• Snack between meals with energy-dense foods like nuts, seeds, or dried fruits.
• Stay hydrated, but avoid filling up on water immediately before meals so that you can consume more calories.
• Incorporate strength training exercises to build muscle, which supports healthy weight gain.
• Rest adequately to support muscle recovery and hormonal balance.

According to one study covering adults across five countries, adults who actively tried to gain weight were much more likely to increase intake of calories, fats and other nutrients. Gaining weight can be difficult for some people. A few changes like adding healthy calories, eating smaller meals more often, and snacks between meals, can help you gain weight safely. The research supports the expert’s advice: it’s about adding good calories and eating smartly, not just eating more.

Things To Watch Out For

• If you gain weight too fast, it may be mostly fat, not muscle
• Relying on snacks and junk food may increase calories, but miss out on nutrients
• If you have health conditions (thyroid, digestive issues), consult a dietitian or doctor
• Gaining lean mass (muscle + healthy fat) is better than just any weight

Gaining weight doesn’t mean eating anything and everything, as it means being smart about what you eat, how you eat and why. Dr Chaturvedi’s advice shows that with the right combination of nuts, dairy, healthy fats, starchy carbs and protein-rich foods, you can boost calories and nutrition. If you add consistent eating habits and strength work, you could start seeing healthy weight gains within a week.
