How to gain weight?

hi

I am 22 year old and i have never gained weight instead i seem to be loosing weight. but i feel like i am carrying the weight of someone who weighs twice as me. i weeze alot and feel like something is on my chest. i do have allergies and do eat, alot, but still no change in my weight. i really do want to gain weight so i would like to know could the chest pains i feel and allergies, be responsible for my lack of weight gain, should i see a dietician or a GP?

A  person can lose weight sometimes when breathing is ‘labored’ due to an issue with the lungs, because calories are used more for the body to breath. Suggest you see a doctor to find out why you are having issues with your chest. It is important you are eating healthy and try to eat 3 meals a day with snacks between meals. A Heart Healthy diet will give you the nutrients, vitamins and minerals your body needs, gain weight slowly, and help with possibly preventing future disease states. Heart Healthy diet which is a moderate fat diet and a moderate fat diet means = using polyunsaturated (omega 3, corn oil, nuts, etc) fats and monounsaturated (olive oil, canola oil, peanut oil, etc) fats, no saturated fats (high fat snack foods, butter, fat spreads) and no trans fats. Eat low fat meats (chicken, fish, loin of pork) or non-meat sources (soy products, nuts), low fat vegetarian combinations (rice & beans, pasta & beans, low fat cheese & pasta), low fat and substitute dairy products (1% milk, low fat/fat free yogurts, low fat soy milk/soy yogurt), use plant oils, non trans-fat margarines, and eat a lot of fruits and vegetables. Eat daily high fiber breads and cereals (oatmeal). Thank you for your question.
