Welcome aboard @CrowsInMyGarden
First of all dont be so hard on yourself, we all have made bad choices in our pasts, we are human :)
But well done that you have finally plucked up the courage and determination to make the changes you need to get back on track
Im 5ft 1 and a wee bit and joined SW at 11.7stone.
Im an active alcoholic
Yes you can lose weight if you follow the plan
Yes because of age and size it will be slow
And yes you will see a big improvement on your tests results - if you can knock the drink on the head, or at least keep within government guidelines , which have dropped again recently I think ? Used to be 14 units, Im sure its been dropped , and what alcohol you do drink is spread over 2 or 3 nights, giving yourself alcohol free days
My tips as a target member? Wear the same clothes every week. Dont weigh at home, just the one weigh in at the same time of day. ( I went first ever weigh in in vest and 3/4 leggings and flip flops - its been hell during the winters lol )
Try to make your food more whole food then processed . Im not vegan nor vegetarian but I prefer to choose beans and lentils for filling meals. Eat your fill of speed fruit and veg and up your water intake - you can use sugar free cordials to flavour
Stay for the group sessions. totally invaluable in getting support and mixing with people who have the same goals. I find the support a real boost, when Im having a bad week, when Im drinking the head of myself and finding life tough, the group is there for me, as I am for them, celebrating their successes and supporting them through their dark times as well
Exercise is great for your health. I go walking. I walk for miles every day ( not this past week because the ice is so bad, not even the dog can stay upright ) but Im usually out there clocking up five miles a day every day - rain, sleet , snow - out I go. But any form of exercise will boost your mood and when you are feeling better in yourself, you want that to carry on so you become more motivated
Dont say sod it and jack it all in if you have a gain. Weight loss isnt linear, it goes up and down. Dont panic if you have a bad day and stuff yourself silly, just start again with the next meal
So use the group and use here. We are a friendly bunch , stick around :)
