There have been a lot of good points made here and all I can do is basically regurgitate them with maybe a variation.
So instead I am going to ask YOU some questions. You sure as heck don't have to answer them here, or to me directly but you might find if you take the time to sit and write the answers out they will help. I had to do this, and I do it regularly with myself to re-evaluate things and why I self-sabotage.
1. Do you want to lose weight?
a) If this is a yes - is it for yourself, your children, or because others want you to?
2. What are your problem foods?
When you have your list answer these:
a) Do you keep these in your home?
b) Do the math and figure out the total cost of these problem foods (current value in your home, and total value you spend monthly).
c) Do you actually like spending that money on those things or can you think of something you would rather have or do with that money. And I mean LIKE it a LOT.
Then do yourself a favour and remove them from your immediate reach. If you have to take the non-perishables to your car and put them in the trunk... Do it. If you can donate it to the food bank... Do it. If financially you feel you can't do this right now then sit and make a list with the cost of healthy foods and put it side by side with the junk food list. This part stings for me - my wallet takes a pound when I eat junk and amazingly enough it offends me. A lot.
3. What is your end goal? Some have a weight range, some have a size range, some have a health goal, and some have a combination of these.
4. Do you find your end goal overwhelming, and find it stresses you out to think of the big picture?
a) If this is a yes have you considered making your goals smaller increments?
b) Do you have anyone whom you can work with on this... Not a Doctor, or a family member, or someone who is encouraging you but not in the same spot as you, but rather someone who can talk things out with you, and work along their journey at the same time. (Even a mentor who's already done this can be very cool but a buddy system often works to get one through the hard times.)
5. Is there any other life stress (no matter how small it seems) that is bothering you or causing anxiety? Can it be eliminated or reduced? And please remember that often times it is not just bad things that cause us anxiety. Heck... Scan through my recent posts. I have all the reason in the world to be happy right now but I am still wringing my hands and wanting junk food!
When you are done... DO NOT READ IT RIGHT AWAY! Put it away till the next day. Then after a healthy meal sit down and read what you wrote.
P.S. I'd love to say the bowl of chips sounds disgusting but I can't. I just know that if I do cave I do it with moderate portions now (most of the time) and I don't self-flagellate over the times where I do a major mess up. I just reassess my self and what is going on.
