After querying how good my body fat monitor was I found this info.
As I follow the same procedure every morning, the results I get are probably reasonably meaningful.

Handheld body fat monitors measure body fat by a process called bio-electrical impedance analysis, or BIA. According to the American College of Sports Medicine, BIA measures body fat with the same accuracy as skin-fold calipers, trailing only hydro-static weighing for accuracy. To achieve this level of accuracy, however, you need to follow strict protocol for use.

Function
BIA measures the electrical conductivity of your body. As you hold the device in both hands, an imperceptible electrical current passes through your body. Muscle tissue in your body contains a high percentage of water, while body fat contains virtually no water. Because water conducts electricity, the ease at which the current passes through your body determines your body fat percentage. Using equations and assumptions about average hydration and body water content, handheld BIA monitors display a body fat percentage to the user.

Considerations
Handheld BIA devices do have a reported error between 3 and 5 percent for a variety of factors. Different genders, ages and races may have differences in body water content, thus decreasing the likelihood that one machine can deliver accurate results for everyone. Some devices do allow you to set age and gender, increasing the chances of an accurate measurement. Meal timing can also affect the results, as undigested food in the body can skew results. In addition, recent exercise can alter results as exercise alters body water content.

Method
To properly use the BIA device for the most accurate results, you must follow a strict protocol each time you get measured. You should use the same device for each measurement, and calibrate the device prior to each use. You must follow the same eating, drinking and exercising routine prior to measurement in order to ensure accurate results worthy of further analysis. Changes of 4 to 5 percent can occur from differences in hydration status alone, making consistency important. The same person should also administer the test each time, whether yourself or a clinician at a health club.

Interpretation
If you follow a strict protocol, the device displays an accurate body fat percentage, which you can further analyse. Your body fat percentage reflects the amount of your body composed of adipose tissue, also known as body fat. Subtract this percentage from 100, and you get your body's lean mass, that part composed of muscle, bone, water and other tissues. The higher the percentage of lean mass, the better. In general, ideal body fat percentage for a man falls below 22 percent, and for a woman below 30 percent, although age-based standards vary.

Shocked to find I was 15 stone this morning, after being sub 14 stone exactly 6 weeks ago. My weight is totally out of control. I have been here before (25 years ago), and it was disastrous then, as I gained more weight than I had lost.
My first act was to share the news with my wife, as I need her help to break the pattern. As of today, everything has to be weighed and counted. No exceptions. I will also adhere strictly to 16:8, eating no sooner than 10:00 and no later than 18:00. This will also have to be followed on working days, so no breakfast before I go out. I am terrified that things just slide back to what they were.

Quite mild here considering it is St Andrew's Day and that tomorrow is the first day of meteorological winter. Been out to shops a couple of times this morning. I look forward to my days off, but then have to try and catch up on the things I put off while working. End up my "off" days are never as relaxing as I had imagined they'd be!

Pleased with that. My weight has been dropping all week and I am thrilled to be sub 200 once again. I think it is more to do with the low temperatures, and my body burning energy to keep warm, than it is diet. Mind you, my waist has stayed the same during all the ups and down. Wherever the weight is going it is not on my tum.
Today is the last working day I have on my books, but today we will see what Lorna, my Branch Manager, has planned for December. Hope it is not too busy.
My son says that his mum expects to get home sometime next week so life is beginning to return to normal.

I am having terrible problems controlling my eating at the moment. I start the day fine, with my breakfast weighed and counted and my packed lunch (usually Macadamia Nuts) the same, but when I come home in the evening all I want to do is eat. And I do! I just cannot help myself. I know it is stupid, and totally under my control, but that makes no difference.
It is another shiny bright sub zero day here. I am not working today. Instead of driving I'll be driving! Makes a nice change!! My wife has a dental appointment in Edinburgh so I will drive her across. I hate driving in the city centre but at least we won't be there in rush hour.
My work gave me a lovely, thick, warm beanie hat yesterday, with the company logo on the front. What a difference that made to keeping me warm. Especially with my 2 and a 1 haircut. It is amazing just how cold the van can get between trips. Fine when you are driving, but chills quickly when it is parked up. And woe betide you if you leave the engine running while parked.
