Just thought I'd pop in to share some info that may be beneficial to others.
At Xmas I weighed 177KG. Scary I know, but that's what a sedentary lifestyle and food addiction can do! So I had one of those rare and beautiful moments of clarity, and woke up to what I had done to myself, to how I was letting myself down, and knew I'd had enough of it, that I had to change, and for good.
On January 2nd I began my mission by cutting out most carbs, just getting enough from vegetables like broccoli and cauliflower which I'd eat with a steak or salmon for dinner. Though sometimes I'd have baked beans. Breakfast was scrambled eggs, or a few sausages if I was working. Maybe some chicken for lunch. I lost around 10kg in January just by doing this.
At the start of February I began walking. I couldn't do it for very long, averaging a few kilometres each time, three times a day if not working, and twice if I was, before work and after. I think I lost about 7kg more. I'd do the odd treadmill walk in the gym if the weather was poor.
By March I was able to do around 3-4 km per walk, two to three per day, every day, and got down to around 155kg, eating similarly.
In April I tried Keto for a week and lost 5kg more, but felt kind of low. I think the severity of carb restriction caused this, so despite the results I stopped Keto. Instead I began intermittent fasting with roughly a 16 hour fast and 8 hour 'feeding' window. Basically I'd eat a breakfast at around 9am consisting of scrambled eggs or a few sausages, and steak/salmon/chicken with veg at 5-6pm. I was getting a bit fitter and regularly doing 5km per walk. I was hungry at first between meals and in the evenings, but soon acclimatised, and my determination was very strong, so I didn't find it too difficult.
This is when the weight really started shifting! The science behind it is that around 10 hours or so after eating your body begins to run out of the glycogen it created from the food you last ate, and instead burns fat for energy. So when sleeping you're often burning fat, and when doing exercise in the morning, before breaking the fast you burn fat. So I stuck to this bar cutting out the sausages. I now only eat non-processed food.
In May I was walking 6-7km each time, and getting faster. By June I was often doing 7-8km each time, and at the start of this month I joined a gym where I'm doing resistance training with a personal trainer. I'm still walking and now swimming too. My weight is now 112kg, I've got as much energy as I had 20 years ago, and more determination than ever. My goal is around 100kg though it'll probably take a few months to get there as I'm building muscle while losing fat.
So having tried several different things I've found that along with exercise intermittent fasting is by far the best way to get in shape, while keeping carb intake relatively low, and eating whole, fresh non-processed food.
I've lost 65kg now, or 10.2 stone, in just over six months, and people I don't even know are stopping to congratulate me, having seen me walking over the last five months.
I'll never be unfit again!
I hope this info is beneficial to some.
