Of course it is hard to lose weight. If it was easy, we wouldn't be here, would we?
For myself, there are a lot of things that make it hard. I am tandem nursing, and I am slow to catch on that this apparently has a huge impact on my ability to lose weight. You'd think I'd have figured that out the first time around!

But it really took me this long to figure out that the biggest difference between losing 30 pounds between pregs #1 & #2 and only 10 pounds (not counting pregnancy weight) between pregs #2 & #3 wasn't eating or exercise, it was nursing two kids at once. Not that I would change it for the world, of course, but finally figuring that out has removed a
lot of pressure.
Also, for myself there is the reality of scoliosis. I've been told that the curve in my spine is readily visible when I'm shirtless. I've also been told that I have a bunching up of muscles on one side of my spine, which further complicates matters, and yet further a twist in my spine. Which means that I have a bad back, and sometimes I wake up in pain and go to bed in pain and it's just impossible to exercise.
That's the physical stuff. Mentally:
I am self-indulgent. Got the habit from my mother (not that she indulged
me, mind you!). I have a sweet tooth and I tend to feel entitled to that candy bar. I deserve it, I tell you!
I also love food. Especially Mexican food. Mexican food and pastries. Especially Mexican pastries.

And barbeque. And American-style Chinese food. And fried things. Chicken fried steaks, Popeye's chicken, McNuggets. You name it, frying it makes it better. Adding cheese and bacon makes it heavenly. Oh, and I hate cooking. I mean, I enjoy cooking in
theory, but in practice it's boring as heck and there's zero recognition for it (yes, I need constant petting).
I'm also rather lazy. I am used to being limited in what I
can do, and most of my skills frankly are in things that involve sitting down. I'm far better at writing and crocheting than at playing soccer or softball.
And on a practical level, I have three small children to take care of, including one who really cannot be left alone any length of time when she's awake, and who lately's been sleeping only half an hour at a time during the day. Which means I have to deal with my children's schedules and my husband's schedules and all the stress that comes from my relationship with him, with being so far away from friends and family, and with what is right now an incredibly uncertain future. Quite honestly, exercise is often the last thing on my mind, and I
love activity when I can motivate myself to do it.
