I too have a BMI of 30 - I was surprised to learn. I'm in petite Next 14 (bottom) / 16 top. Hardly the outsize dept but still in the overweight category.
There's dopamine and other feel good hormones that kick in when we ANTICIPATE eating pleasurable foods, we call the slump afterwards a craving. Food activates the neural pleasure pathways like other addictions and pleasurable activities. So it's very hard to control this hard-wired biological urge. But we can.
This is the first time I've been to a weight loss group. It's not the first time I've changed unhealthy habits, though. And like doing a dry jan or quitting fags I've prepared accordingly.
I had a treats cupboard - I asked the teens to clear it for me (It only took them two days
) - I've used up all the less healthy options like coconut cream and changed over to low fat coconut milk for curries and things. It's early days but the first week I didn't plunge straight in and go from zero to hero I just got to grips with the new/changed regime.
However I am looking to make long term changes to the way I eat and I don't look at it as a "diet" more a healthy eating habit that I want to aquire. However, thankfully, my mother seemed not to have passed on any body or food issues to me despite having struggled and been constantly dieting herself. This may have been due to the fact that I was at boarding school between the ages of 11 and 15, you were lucky to consume enough calories day-to-day to stay healthy. :/
I'm menopausal which is why I've gone, the weight seems to be piling on even though my eating habits remained as they have always been, so obvs my body is changing the way it uses energy and my endocrine system is less active, so something has to change. I'm not interested in doing more exercise (Walking and a couple of classes a week, plus cycling most days)
Also I like to think about my food over the space of a week, I have not-so-hungry days and very-hungry days.
