Quick answer: To gain weight healthily, use protein powder to add calories and support muscle while eating in a slight surplus and training with resistance. Blend it into calorie-dense shakes (milk, oats, nut butter, banana) so you build muscle and strength, not just fat.
Healthy gain vs just eating more
Gaining well means a modest calorie surplus plus resistance training, so most of the gain is muscle. Protein supplies the building blocks.
