This is my battle too @Angelo. I've let some kilos creep back on since I lost a lot for my DIEP last year.
I've taken a lot of professional advice and it echoes what the folk above have said. Start small. Pick one thing you want to change. It takes a minimum of three weeks to establish a new habit. So pick one thing you want to change. Not the hardest one! Maybe change breakfast to be a healthy choice, or reduce the sugar in your cuppa. If you always have a biscuit at morning tea, make it a couple of mandarins. Get that habit rolling, and when you feel strong in it, choose the next one.
My dietician said sometimes it's easier to get going with weight loss when you see some quick results on the scales. So she said that it's OK to do a meal replacement programe (shakes for two meals a day) for two or three weeks to start the ball rolling.
I like to build in non-food rewards, like I'll treat myself to a pedicure when I've lost five kilos or somesuch.
And the old making yourself accountable is good too I reckon. Find a friend to exercise with you every week, be it a walk, a ride, a swim, a tai chi class, yoga. All of the above! We're much less likely to allow ourselves to weasel out of exercise if it means letting down a mate.
Women lose muscle mass quickly once in menopause. The more muscle you have the faster your metabolism. Plus it's good for our bones. Going for brisk walks is great but it won't cut it on its own. Gym or weights at home. Which is better for you? I found a 4kg weight in an op shop for three bucks. I leave it lying round where I can see it and try to use it every other day.
Think laterally about exercise. Dancing, or bushwalking, or a team sport? Circus?! My husband keeps himself moving by refereeing basketball at the local stadium.
There are stacks of sponsorship charity efforts you can make. Dry July or Feb Fast for giving up booze. Not only do you make yourself publicly accountable, but you raise money for the cause of your choice. Google 'walking challenges' and your area and see what you come up with.
Vanity can be a big motivator. You want to wear 'that' frock to a do. Is there a wedding on your calendar that you can set your sights on?
More and more science is emerging round hunger, weight loss, healthy fats, sleep, gut health and more. You could do some research and see what you can tweak. I struggle to go to bed at a sensible hour. It's no use me declaring I'm going to go to bed two hours earlier. Never going to happen! But I'm making some real headway with going to bed half an hour earlier. And once that's locked in, I'll trim off another half hour.
I think you have to really search yourself, to understand yourself, to understand what's holding you back. If you can get a handle on the psychology it might help. Maybe a handful of sessions with a therapist could help.
I don't know if any of this is any use, but I hope so! Come back in three weeks and tell us how you've got on. All the best, K xox
