Megastar10000000:
I just want to be as fat as quickly as possible
there are a hundred threads on this topic, so maybe do a search of those. but here are my points of advice after having gained 300 lbs:
1. increase your calorie intake. it doesn't really matter what - just eat more. eat larger servings, eat more frequently.
2. eat what things you like, and which inspire you to eat more, and keep eating. this was the biggest factor for me. eating more, better food - more diverse foods. this awakened the foodie inside me, which was the single greatest driver for making me really fat.
3. the top two will naturally result in this, but the third tip is: increase your stomach capacity. by pushing yourself past the point at which you normally feel full, you are literally stretching your stomach. it's capacity is increasing. it takes time, but you will know it's happening when you can eat more in one sitting, and you feel hungrier more quickly.
good luck, and remember to enjoy it!
