My height is 175 cm and weight 58, many specialist tell me that my weight should be 75 according to my height, so how could I gain weight and how much time will take for it.

Question

1. Keep a food diary.
Chart what and when you eat every day for several weeks to learn about your eating habits and identify places to add calories. 2. Add it up.
Try adding an extra 200+ calories a day in the beginning, and adjust up or down depending on results.
3.Focus on quality, not quantity.
Even when you’re trying to gain weight, burgers, chips, and milkshakes all day (’err day) isn’t great for a body. Instead, choose nutrient-dense foods from all food groups.@Good options include whole grains like whole wheat pasta, fruits and vegetables, nuts, and lean protein.
4.Eat more frequently.
And never skip meals! It’s easy to feel full fast when you start introducing more calories into each meal; changes in food intake might also bring on gastrointestinal issues and even acne. Make things easier on your belly by spreading calorie intake out over five to six smaller meals throughout the day.
5.Snack smart.
Choose calorie-dense snacks like nuts, cheese, dried fruits, yogurt with granola, avocados, and pretzels or whole grain crackers with nut butters or hummus. If leaving the house for a while, pack snacks for calories-on-the-go.
6.Drink it down.
Instead of diet soda and other low-cal drinks, choose filling, high-calorie beverages like smoothies, healthy shakes, or liquid meal replacements. Drink fluids in between meals to add calories and to avoid filling up on beverages during meals (which might make people eat less solid food).
7.Eat before bed.
A lot of healing and regeneration happens while we sleep, so eating before bed can give your body the nutrients it needs to do the work. Nom down on a PB&J or a wrap with avocado, vegetables, and lean meat or cheese.
8.Set attainable goals.
And remember to be patient. Just like weight loss, weight gain is a process—and often a slow one. Gaining might take years, so don’t give up hope if you don’t pack on immediate pounds. The rate at which a person needs to gain weight depends on their health goals and current health status, and a physician or nutritionist can help establish a reasonable goal weight. Signs of reaching an ideal weight include increased energy, stabilized hunger patterns, and overall good health.
9. Get support.
It’s important to have a strong support system throughout the process of gaining weight, both to help gainers achieve their goals and to cope with the emotional issues that might arise from bodily changes. One of the best ways to adjust to changing size is to spend time noticing and appreciating how your “new” body appears in the mirror, says Greatist Expert and psychologist Ellen Langer.
10. Dress well.
Don’t put off feeling good about your appearance. Talk nicely to yourself and choose outfits that make you feel good, no matter what you weigh.
