text: i want to gain weight quickly. what should i include in my diet(veg) ? i only eat boiled egg and omlette in non-veg diet. does omlette help in weight gain if you want to gain weight quickly you need to consider your carbs and proteins. eggs are great for increasing fat in your body but not necessarily weight cause they are low calories.   refer to higher calorie and higher fat foods. go for the following diet:   breakfast - 3 oranges squeezed + 2 pieces of toast w baked beans and butter snack - 2 long savoury type biscuit w butter cheese & tomato lunch - 2 soy & linseed sandwiches w butter, ham, cheese, tomato gilled or 3 egg omlette w cheese, ham, tomato. snack -  banana & honey smoothie (full cream milk)    dinner - always eat rice/noodle or pasta based meals with plenty of vegies  this should do it.
