Hi i am so skinny and my height is 178 cm and my weight is only 65 kg i want more weight in my body please help me to get it.

Weight: Please start w/a visit to your doctor to make sure all is well medically. Work on developing more muscle mass. That can increase weight and tone up your body. A certified trainer at a gym can help. See a nutritionist about a good diet, likely higher in protein and good fats such as coconut oil and olive oil. Love self and others no matter what weight. Peace & good health.
