I have made some progress but it is going to be a hard slog
I know where you're coming from and empathise with you as you start on this journey. Been there, done that, still wearing the t-shirt
It will take time but if you stop thinking of it as a slog that will help - it's psychological. Thinking of it as a slog makes it something you have to do rather than something you want to do and, without any real consequences to giving up, it will be easier to allow yourself to slip into bad habits. Trust me ... I know
I'm sure you understand this but it's worth saying that exercise alone will not result in any significant weight loss, but it does help in conjunction with a healthy diet. What exercise will do is increase your fitness, increase your metabolic rate and improve your well-being, all of which will make losing weight easier and, dare I say it, more enjoyable. What more enjoyable way of exercising can there be than riding a bike?
Whenever I fall off the wagon late night snacking due to a mix of boredom and habit is always my downfall and I find it a very slippery slope. To counteract the desire to eat something I keep a bottle of water or squash by my chair and sip on that instead of heading into the kitchen for my fix. There is some science behind this; the water hitting the stomach fools the brain into thinking it has been fed so the desire to eat is suppressed (or something like that).
For context; I'm a 69 year old, long time obese person, I mean 30+ years of being clinically obese. In the past I have successfully lost weight by following the Slimming World program but being part of the hive doesn't suit me so I didn't keep it up for long and finally gave up on the yo-yo effort a couple of years ago. Since then I have steadily lost weight and am now more than 25kg (4st) lighter but earlier this year I was diagnosed as being pre-diabetic with my weight being the major contributing factor. I have always worked better when I have a firm target to work towards so I signed up for the London to Brighton cycle ride happening in June 2024 and also set myself a target weight which will help me achieve the L2B ride. Since February I have lost 10.9kgs (1st 10lb) and am no longer pre-diabetic but I still have a way to go.
Good luck on your journey
