Is it okay if I have a day where I eat whatever I want?

Hi, I'm 5'3 and 91 pounds. I'm supposed to gain weight up to about 97-100. I don't eat very much but lately I am just craving so many foods; so I'm planning a day where I can have whatever I want. I'm not talking an extra piece of pizza, I mean with all the things I would like to eat it would probably be about 3500 calories (1 pound). I know I will gain a couple pounds, but that's okay since I'm expected to gain it anyway. I know that I can't continue to do this but now since I am underweight would it hurt to have one day like that? what sort of effects would it have?I'd also like to add that I exercise and eat healthy (lots of vegetables and fruits) most of the time and I'm not planning on making this a regular thing, definitely not weekly.

Recommended Answer:

health wiseunless those fats are the healthy type (guessing not, you suggested pizza), you can have severe heart problems, sometimes fatal, if you make this a habitif you want to do this like once a month go for it, but once a week is too much,plus this is a way to build bad habits, and soon that 1 day will become 2, then 3, and so on

• It is absolutely fine to have one day where you are able to eat as much as you want. As long as you dont indulge yourself like crazy I dont see any type of bad things that will happen to you. It is actually a little healthy to indulge every now and again so your body can consume anything that you might not be getting.
• Why put crap into your body? Weight is not the only indicator of health. In fact, it is can be a very bad one, as it is very misleading. Someone can be in the right weight range and be totally unfit. If you eat proper portions sizes, a balance diet, and get plenty of cardio and resistance training, then your body will equilibrate to its natural weight, which will be healthy, regardless if the number on the scale. Stop worrying about your weight and make an effort to be healthy.
