I used to eat "The Zone" diet (which is basically the normal day above, but with a few extra carbs) 7 days a week, plus HIIT 6 days a week, and I was fine - I wasn't hungry as long as I ate my 2 snacks between meals, and I maintained at about 51-52kg. I then got cancer and got hungry on chemo (you have to take steroids) and I put on about a stone up to 59kg and managed to do about 3-4 HIITs a week. I then had to take a complete break from exercise for my surgery and took drastic action once that was all healed from: a 10 day fast (medically supervised at a German clinic) which got my weight back down to about 53.5kg (and saved my sanity - lots of meditation etc.,) but marathon training has completely ballsed things up... I feel super fit and I love running for miles and miles, but it has made me starving all the time, so am back up to 57.5kg (as of today).
I know that's not heavy, but when you are used to be about 52kg and seeing abs, it does feel blubby to me (even though I know I am running fit). I keep trying to reconcile in my mind that I am weighing more because I am fueling my body for this impending marathon, but when I can't fit into any of my skinny jeans, I promise myself I will eat less again (hence bootcamp - day 3 today and going well!)
I just want to be like I was pre cancer I guess. But deciding to do a marathon (surprisingly to me!) hasn't helped with weight and shape - it's made it harder. But I am on the taper now so am replacing runs with Insanities and Ab Ripper Xs so hopefully my shape will start to change!
Managed to stick to the diet yesterday - I can't fast today as am meeting friend for lunch so it will be Weds and Fri this week. Today I have had a bowl of cereal for run, and 2 boiled eggs for a snack - out to lunch at 1pm - will eat salad.
Sorry - that is an overshare - I am just thinking a lot about it at the moment.
So in answer to your original question, I am bloody starving on this current diet but only because I am running 40 - 60 miles a week!
