It is difficult. to succeed at overcoming nature and genetics. Weight and habitus are primarily determined by genes, but can be overcome by environment and lifestyle. Although being thin is viewed as a person looking unhealthy, the opposite is true. Obesity increases the risks of diabetes, heart disease, and many cancers. The healthiest option is to eat a well balanced diet, and exercise to built muscle weigh.
Need more weight. Hi TaliyaM, my best suggestion is to find a dietician. Not knowing your BMI, weight gain needs to be monitored just as much as weight loss. There are obvious ways to gain weight (fast food, high caloric foods) but i would avoid those as they are extremely unhealthy. It may be as simple as supplements added to an otherwise healthy diet. Do it right, see a dietician, and you'll thank them. .
