For most people (myself included) being overweight has happened as a result of over eating to varying degrees; for me, I use food as a comfort blanket:
Bored? Grab a blip
Down/Anxious? Grab a blip
Happy/Joyful? Grab a blip
I can try my hardest to be "good" but the blips are/were always around the corner. Why? Well I don't actually know, today I thought to myself it's kind of like an addiction, I don't smoke and I only have the odd alcoblip. Is food my vice? Well I think it is really. When I think about the reasons people with other addictions use their substance of choice, well that's food for me.
That thought made me understand myself so much better. If someone is battling a drug addiction, there are many forms of help, including substitute substances and rehabilitation. The advice is never "well only snort one line this weekend".
Maybe this is why I have constantly had setbacks before my current diet, by saying to myself "just eat less" well that's not helpful is it? My point being, addictions come in all forms, food is not given that understanding, it does have as disastrous consequences as any other addicition substance.
So now I look at my meal plan as my rehab; and when I'm done with my rehab, there will be certain foods I will absolutely avoid, these will put me right back where I started; and this is ok, afterall someone who is "dry" is praised for not keeping alcoblips in the house.
