Gaining

Gaining for dummies

Increase the size of your meals, little by little. Before long you're appitite will adapt to the larger portion size.

Add snacks throughout the day. If you want to be a bit reckless, have something sugary whenever you feel thirsty or sluggish (still make sure you get enough water of course). Before long it'll become instinctual.

Make sure to have something high in calories before bed as it'll be more likely to be converted into fat due to you're motabolism going into rest mode while you sleep.

Binge on the foods you enjoy. Sweet and salty work well, enjoy crisps then icecream after meals for example.

You don't have to consume huge ammounts of calories all at once to gain weight, just make changes to your habits like these and you will steadily gain. As long as you're exceeding the recommended daily calorie intake consistently weight gain will occur.
