To think I’ll be stuck at 16 stone forever

You're the one who is 16 stone though.

This @justmeandthedogs

10K = 6.2 miles

You're walking at less than 3 mph. (You said 2.7mph.)

At 3mph, 6.2 miles would take you just over 2 hrs.

2.7 mph is looking more like 2.5 hrs.

Also, everyone's steps are different.
Some people take tiny steps, others take huge strides.
Gadgets need calibrating - I'm sure yours is.

Yes and if you were stuck in a survival situation then red meat is one of the most nutritionally complete foods you can eat.

It also contains all nine essential amino acids required for muscle growth, tissue repair, and immune function and contains iron, zinc, and B vitamins (especially B12) in forms that are much easier for the body to absorb compared to other sources, zinc, iron, selenium, and phosphorus and beneficial compounds not found in many other foods, including taurine, carnitine, creatine, and carnosine, which support metabolic and cardiovascular health

Op you mention protein days; have you tried eating protein daily at every meal (30g approx) with plenty of fibrous veg? So always a big salad to start lunch and dinner,

I think you've got the right mindset. Sustainability is always better than speed (although speed would be nice too).

Good luck!

Are you taking progress photos and body measurements? The scale is only one piece of information.

There is no evidence red meat causes anything but great health. I never touch processed meat as it's full of chemicals and preservatives. I eat mostly minced meat because I am on a budget. Lots of eggs and butter. some fish (tinned and fresh). I also sprout and grow low oxalate veggies - mung, alfalfa, lentils, black eye, chick and marrowfat peas. I probably eat what my ancestors eat pretty much although in the ice ages there would have been only meat of course. My maternal haplogroup is from Siberia.

The 10k is arbitrary but it’s more likely to be a case of the more the better. I get an average of 16k aim for a minimum of 12k - desk job but 10-12 min walk to train and I walk my dog.

I'm inclined to agree with you.

Stick with it OP. Sometimes you just get stuck and then all of a sudden, drop a few lb in one go or at least start moving again I know this stage is frustrating, bit carry on and it'll pass.

Well done on your weightloss so far!

How frustrating for you OP.
I would suggest increasing your calories to maintainence for at least a few weeks. When you're in a deficit for a prolonged period of time your body adapts and weight loss plateaus. So if you increase to maintenance for a while, your body relaxes and cortisol decreases. Then after a while if you eat in a small deficit again for a while fat loss should start again.
Phases of deficit/maintenance is much more sustainable and healthier for fat loss.

As well as general movement/activity every day and if you can some strength training.

All the best.

Blimey OP. You have to have a life surely? Not on a treadmill between meetings.

What kind of meat do you eat daily? Does it not bother you that red meat is a probable cause of cancer and processed meat is a known cause?

@justmeandthedogs If you can afford it, get a treadmill, especially if your desk job has any WFH days.

While the kettle is boiling - 30 seconds fast incline walking
Waiting for dinner to cook - 15 minutes fast incline walking
On the phone - x minutes gentle, low incline walking
5 minutes between Teams meetings - treadmill, etc.

It really adds to the step count over the week and the incline raises your heartrate which is great for your overall cardio fitness.

It's also a steady cardio, which means your body is more likely to use fat to fuel it rather than muscle - hence why you see all the bodybuilders at the gym speedwalking Mount Everest on the treadmill.

The 10K steps as a goal is nonsense. Nothing personal there! The whole 10k thing was the name of the Japanese invention for the gadget to measure steps. There was never any science behind it.

I genuinely wonder how many people hit 10K a day- that's just under 5 miles and is close to 2 hrs of walking at 2.5 mph. I do around 7K and that's a 3 mile hill walk, taking about 50 mins, and some days I have shorter walks around town etc to add onto that.

I was curious as it's easier to move at home- a standing desk, a couple of short bursts of walking at lunchtime etc.

I don’t know whether you’ve tried this and I’m sure you’ve tried everything but I do think it might be worth trying varying your calorie counting. So having a couple of days a week where you eat more so you avoid your body going into starvation mode. Also do you move around a lot during the day - up and down stairs, walking round the building etc. that can burn extra calories.

Also a lot of PTs recommend progressive loading to build up muscle; so the body gets used to e.g. a particular workout so you need to increase weight or reps to continue to build more muscle.

Finally interval training is positive for exercise rather than going for full effort without recovery.

Otherwise just keep your confidence and trust the process!

Stop drinking 4l of water a day as you will be retaining water.

It’s soooo disappointing when you are being so good and don’t see results. FWIW I don’t see drops every week, the scales won’t move for 3-4 weeks then over a week I’ll drop 2-3lbs and it will stay off. Then I’ll yo-yo over the next 2-3lbs again. I weigh myself most days, first thing in the morning, after a wee and naked.

Maybe you are losing inches?

Everybody has their own views on WL- try not to get to caught up in everybody else’s ideas/opinions. I like slimming world. It’s great for me. I’m down to 9st (<5ft) and I enjoy it.

Don’t get discouraged- sounds like you’re doing a great job!

Nope. No issues. I feel better than I ever have. Skin, nails, hair all amazing. Sleep like a log. No problem with logs either.
