Running on a caloric deficit

I’ve been eating about 500 calories a day this past week, while running about 15 miles a day, and feel like absolute garbage. My muscles are as sore as they’ve ever been. My BMR is around 3100. I did 60 last week(down week) and am planning on hitting 85 this week. Is the pain I’m experiencing from being underfed, or from the increase in mileage?

If you say so, rotunda.. 3/10, will get some responses.

I’m completely serious, I want to lose weight fairly quickly so that I don’t have to be at a caloric deficit for a longer period of time, so I thought being at a higher caloric deficit was the way to go.

Please tell me you're trolling.

500 a day is way too low. Even people with diagnosed Eating Disorders eat more than that a day (and can still lose weight).

For perspective, eating 1000 calories a day with ZERO exercise is still considered starvation for a huge majority of people.

Think of it like this, there is a certain amount of calories you need to take in daily to maintain your weight. If you want to lose weight, you create a deficit by having a net calorie total less than that.

You said your BMR is 3100, which is very high.

500 calories a day with 15 miles a day gives you a calorie net of about -1000, which is around 4100 calories less than your BMR, you'll lose too much weight too fast and be at risk of severe complications and even death by doing that on a regular basis. No wonder you feel like garbage, it will only get worse.

If you are running 15 miles a day bump your intake to something more safe like 3000 calories. That way your net would be around 1500 calories (which is half your BMR at the moment) and you'll still lose weight, just at a more healthy pace.

Why are you only eating 500 calories a day? That is an extremely unhealthy approach to food. If it's to lose weight, it probably won't work because your metabolism will go into starvation mode and preserve this energy. It will also shut down your endocrine system and mess with your hormones by having a defecit of this size.

You are potentially on the road to an eating disorder(if not already). You have to eat to train as your body needs energy to run and recover. Disordered eating like this will only do damage to your performance and very bad consequences to your health.

You got some serious bites. Pun intended.

I read a personal review about the 3 week diet, and it seemed like the person had great success using the product so I gave it a try. I couldn’t have been more excited about the results, as I am now 50 pounds lighter than when I first started using it.
