I used to drink quite a bit and was out of shape. I'm now gym fit with abs. I thought my decent body was lost years ago, but it turns out I'd just buried it under mountains of bad habits, beer and lack of self care.
I started by taking up yoga. I started with beginner friendly videos, more meditative and not very physically demanding. That's fine, it's about getting your body used to being in a certain space and taking that time for yourself, breathing and recharging. I started to actively look forward to it, which won't happen if you go hell for leather doing an enormous workout routine that your body is not yet equipped to do. If course you will dread it, it will be horrible lol.
I quit drinking. Not wholesale I still have the odd gin and tonic but only on a Sunday and not every weekend. I didn't miss it after a short while. I noticed I had more energy. I didn't wake up starving because the alcohol has messed with my blood sugar. I didn't say 'fuck it' because the beer had lowered my inhibitions, and decide to eat and entire pizza on my own or order take away. This added up fast. After about 2 months I started losing weight and I wasn't really doing anything else.
The weight loss made me feel good. As well as this new found energy. I decided to clean my diet up a bit. Started subbing out something unhealthy for something healthy. Eating smaller portions. Started to cut back on carbs, but not full keto. Eating less bread was the main thing after alcohol that was making me gain weight. I swapped while carbs for brown or high protein versions which are more filling, you can get protein wraps protein, pudding even protein pasta. Blood sugar was more stable so noticed I wasn't as hungry in general. Added fibre to diet because while protein is great and takes longer to digest etc, fibre is what will keep you feeling full. Started having more vegetables in my plate. Stopped eating fruit and sugary foods, I already didnt take sugar in tea and coffee but I cut back on other sweets drinks or drinks that were filled with empty calories.
Noticed big changes with this and my yoga had improved so I stepped up to intermediate, now taking that time to ask my body to do a bit more. The poses were hard. I hadn't yet learned how to balance and I lacked the strength to hold the poses for any meaningful time but that was the point it was all a practice.
Invested in a treadmill. I didn't run. I hate running. Did fast walking for 20 minutes every other day. Got into a routine with both the yoga and the running.
Went to the pub and realised I actually felt a bit sick from just 2 drinks and that I'd be too wobbly to do my yoga, and realised I'd actually have rather stayed in and kept my routine. I was shocked as I used to be the first person at the pub as soon as anybody even suggested it.
Started to up my my game. Bengan hiit on treadmill so fast walk then run then fast walk again. Cardio developed quite quickly.
Yoga was the main thing and for me way better. It somehow made me mentally feel stronger and more capable. It got rid of a lot of stress and I feel funny even now if I don't do it. Started to get actually quite good at it and was surprised how much flexibility and muscle returned. Began doing power yoga and advanced yoga. Sometimes twice a day. Started to run outside - which I still hate.
Started serious dieting (which I won't bore you with here as you don't need it), cutting, watching my macros etc. and revealed that I'd done a shockingly good job of transforming my body.
The whole thing sort of snowballed and I'm very happy with itm it took probably a year and a bit to get where I am now, but instead of having an end goal of being like this, I was just happy that I was achieving at each level, happy with each improvement. That really helped as it meant in the moment I felt good. I felt positive about continuing. I didn't set myself harsh targets like lose 3 stone by Christmas, before next year's holiday or something other occasion which is never going to work and will just lead to feelings of shame and failure all round. Started to count calories through this but wasn't militant with it. If I went over one day, instead of being upset and throwing in the towel I'd count the calories over the week, and know that as long as I was careful tomorrow and the day after I'd still be under in those 7 days. That really helped me get back on the horse and stay on track. Before that when I'd tried to diet I'd make one mistake or have a shocking two days (usually when very stressed or busy) then write the whole thing off as if I'd failed. Rinse and repeat. The actual way to improment is consistent effort, every day. All the times before when I'd failed at diets I'd also not given it long enough. You need to diet and exercise for a minimum of 6 weeks to see results and probably 4 months to look in the mirror and really notice a change. It's a long term goal, but it doesn't require long term thinking because the only moment you control is the right now, so just do what you can in the moment and you will get there.
Bad habits stack and so do good ones. If you do 3 things that day you didn't want to, eg eat some junk food for lunch, followed by a coffee with cream and sugar and 6 biscuits, it's easy to say well I might as well just drink the gin and watch TV later in the day, in the mindset that you have already failed. But if you have made healthy decisions through the day and given yourself the deserved pat on the back for doing it, it's easier to say I don't drink tonight, I'll go on that walk, I'll do 15 minutes of yoga etc. these things are like feelings, they have a roll on effect.
If you live with somebody who is unsupportive you need to make this your thing, independent of them. This is done by you for you, they don't matter. If they seem unhappy about it then it's literally just jealousy that you can succeed where they have failed. You don't need their help or approval to control what you do in a day.
