why does my daily energy expenditure seem so big?

Hello fellow dieters! I'd be grateful if people could help me with the following question.

First, my key data...

I am a 49-year old man, height 5'11" (1.80m), with a medium build and a fairly sedentary lifestyle. I am on my way down in weight from 13st 10lb (192lb, 87kg) to my target of 11st 3lb (157lb, 71kg). My current weight is 12st 7 lb (175lb, 79kg), so I am halfway there!

Over the past 7 days, I have eaten 6105 calories and my weight has fallen by 4.79 lb.

I calculated the weight loss figure using exponential smoothing, so it is not significantly affected by daily fluctuations. My rate of weight loss, my calorie consumption, my exercise and lifestyle have been pretty constant for several weeks, so there has been nothing special about the past 7 days.

My question is, why is my indicated total daily energy expenditure so high?

In 7 days, energy expenditure in calories has been 6105 (food) + (4.79 * 3500) (burnt fat) = 22780. Dividing by 7 gives a daily figure of 3267 calories.

Surely that's far too high a figure, given my shape and lifestyle? I would have thought the figure should be around 1950-2200 calories, and certainly no higher than 2500 calories.

So why am I losing weight at such a high rate?

Thanks for any help with this!

Best regards,

Wow 6105 calories over 7 days or is that the total after what you burnt off through exercise.... maybe I've not had enough coffee ?

Least I aimed for was 1200 calories a day with exercise, I never ate back what I burnt off but at least twice I've had to up my calories to lose as I went into plateau. There is such a thing as not eating enough it seemed.

Between 12-14 stone I was losing anything between 1-4lbs a week just eating healthily and exercising.

Nice one on your current weight loss

I've had my coffee and I still don't understand

Could you explain a little as I'm not sure what you mean because first you say "Over the past 7 days, I have eaten 6105 calories" then you go on to say "In 7 days, energy expenditure in calories has been 6105" and I'm not with you on the + (4.79 * 3500) (burnt fat) = 22780 bit. Could you let me know exactly how many calories you ate (if you know) over the 7 day period excluding your calculated burnt fat and energy equation?

p.s Ok so I get that you calculated the weight loss in terms of energy (calories), however some of that weight loss may have been due to water loss and other digestive causes, so it wouldn't necessarily be that amount.

All the best
