Hi ladies - didn't want to read and run as this is how I felt while conceiving my son (took just over a year) and I weighed less then than now! Might be nice to have a little support group here :-) I've been trying a VLCD for the last 3.5 weeks before we start trying to conceive our DC2 in the next few months. My BMI was ~33; I've managed to lose a stone so far and need to lose at least another to be below 30 BMI. Really, I want to get in a place where I can start some healthier habits as maternity leave (unstructured meals and secret eating) and then the return to a stressful job (eating breakfast and lunch out every day) meant although I gained pretty much no weight through my pregnancy, I gained 2.5st afterwards! The first week or so of the diet was really tough - food craving was pretty horrendous, particularly as I'm still trying to support with meal making for my 18mo. DS and DH (who can eat anything plus lots of snacks and put nothing on!). But the craving did get better. I've even forgotten I'm due a meal at times! The fact we are both working full-time from home with a toddler probably helps. You should try to speak to a GP before starting any VLCD though.
I can also recommend the Couch to 5K app, which you can listen to with headphones as someone tells you when to start and stop. In January, I started a couch to 5K group (which was also difficult at times, particularly on the solo runs) but the motivation of getting healthier for my son helped. I told myself I didn't have to enjoy it - because I was sick of people telling me I'd learn to love exercising - I just had to do it. I got through the first 5 weeks before I caught a bug of DS, during a week the runs were meant to ramp up in difficulty and didn't feel able to join back in. I'm planning to start from the beginning again in my own time now that I'm more settled in my diet, using the app and just doing each week's runs when I can, repeating weeks if I need to. It is going to be hard, but I would feel better about TTC if I knew I was doing what I could and trying to be more positive about myself, instead of blaming myself for it taking a long time to conceive the first time (when really I don't know what it was and won't know till we try again whether DC2 will take a while or not!).
If anyone needs some support (with diet/exercise motivation) or just a venting space, would be lovely to hear from others in the same position!
