I carry my phone with me always so my son can track my butt if I go missing or need help.  Why?  I have had low blood sugar spells where I don't remember where I am or what I did.  I have a cute little belt I put under my shirt and carry my phone, id and keys.  

The only exception would be if we are in an area where there is no cell service.  My kids rented a place on the cliffs on pacific coast hwy this weekend and there was no cell service, but I was not alone either.

To each their own. I do it for safety  LOL my son said when I start disappearing he was going to chip me LOL

Increasing your calories will allow your body to retain weight and fat.  The only way to lose weight is to eat less calories.  The advice you are seeing is not for people who had weight loss surgery.

To lose your weight and maintain your loss you will always have to eat less calories than you did before surgery.  Surgery was a shock to your body.  It had to do with less food than before and it will always try to gain the weight back.

The fight is not over at one year or ten years.  Workouts are wonderful for your health but only cutting calories will result in weight loss.

My iPhone has my contacts, my mail, my internet and Facebook, my banking application, My Fitness Pal, my fitness tracker software, my music, my weather and my maps.

I could understand a person with a phone that is only a phone not needing to be connected to it.

I would suffer anxiety without my iPhone on my person.

That's kinda a snappy answer.  She asked you a specific question & you gave a you just wouldn't understand type of response. As beautiful as that picture is, I'm sure if you twisted your ankle, or broke your leg etc, you'd wish that you'd be able to contact someone. The scenery will be the last thing on your mind in that moment. I'm sure it will change you forever too.

The thing to remember if having a phone really distracts you like that, to make sure you contact someone as to what trail you're on, how long you'll be out & when you expect to be back, that way if something did happen, someone will look for you.You'll just have to take care of yourself in the meantime. Most if not all of those people who go on those nature hikes where cell service is iffy at best, tells someone else of their plans.

When it comes to eating back calories, I have a personal rule of thumb.  Anything under 500 burned and I don't worry.  Anything over 500 and I eat back some.  Now this can change depending how I feel, how hard the workout was, etc., but that's my general guideline.  If you want to eat calories but are worried about eating too much volume, look to nuts and nut butter.  Lots of good calories in a small package. 

As with a lot of this stuff, it's very personal.  Experiment and find what works best for you.
