Hi there. Thank you for the question. Your weight according to your BMI is 17kg/m2. You are definitely underweight. However, if you want or need to gain weight, do it the healthy way -- which is not about overdoing it at an all-you-can-eat buffet. Here are some tips to help you put on some healthy weight:
- Calories Count, But So Do Nutrients
Calories also mean energy, or how much energy you would get from a specific food. Some foods are calorie (energy risk) for example high in fats like a plate of french fries, but nutrient rich means foods that re high in vitamins and minerals (for example yoghurt, with muesli and chopped fruit) or a chicken wrap with vegetables in a brown tortilla wrap.
Focus on healthy foods to gain weight, because even though you have more leeway with calories, good nutrition still rules. Weight gain requires eating calorie risk foods but also nutrient- rich foods- not just high calorie foods with lots of fats and sugar. Your goal would be to choose foods that are packed with vitamins, minerals, nutrients, and calories so each bite is loaded with good nutrition. Start with nutritious foods and then wherever you can, enrich the foods with additional ingredients like yogurt, fruit, nuts, and healthy fats (add olives, avocados, olive oil, light mayo to foods)
- Eat Often to Gain Weight
Regardless of why you want to gain weight, eating meals or substantial snacks (think mini-meals) more often is the way to pack more calories into the day. Try to eat six times a day, with each meal (or at least three of them) containing protein, starch, vegetable[s], and fat. A sample meal: a chicken sandwich on whole-grain bread with mayonnaise, baby spinach, peppers and tomatoes and a fruit smoothie.
Eat often and choose wisely, and you can expect to gain an average of 0.5 to 1kg per week. Snack on fruit, nuts, even a shake for example (nutren active/ ensure) will be good enough. Try blending the powder with low fat milk and fruit to make a delicious smoothie.
Gaining Muscle Mass
The best way to gain weight would be to gain muscle at the same time, and not just fat. That is why it is important to look at your meals and choose wisely. Choose frequent, healthy snacks to fuel your physical activity. Try to write down what you eat and analyse it at the end of the day. Gaining muscle mass does take some time and investment and most often, once analysed, people who are trying to put on weight do not actually eat as much as they should!
If you are still not sure about how to go about this the right way, consult a dietician in your area to get a full assessment or meal plan.
