Hi M@L

I figured it would be a bit of a crazy goal, but it's a motivator nonetheless. 7200 calories is hectic, don't think I could manage that.

I'll just carry on the way I've been going and hope for the best. In the past 3 days, my calorie burn according to the gym's cardio machines has been 400 - 450 - 510. I'm very chuffed that I've been able to increase my work rate to burn more calories per workout. I'm going to try and do another 500calories tomorrow morning and work as hard as possible during my 90 minutes of squash on Sunday.

That's the best I can do from a workout perspective, so let the chips fall where they may. Thanks for the info! :)

There are 9 calories per gram of fat. So technically, to lose 800 g of fat, you would need to run a calorie deficit of 7200 calories.

Bear in mind that a healthy and sustainable rate of weight loss is generally 0.5 to 1 kg per week, and .8 kg in 3 days is not a healthy approach.

Also, a dramatic increase in your level of working out is likely to result in your muscles retaining water (at least in the short term). So even if you manage to burn 7200 calories, this probably won't show up as an exact 800 g loss in the scale.

I weight 101.8kg and would LOVE to lose those pesky 800g by my next weigh-in on Monday morning. I'm willing to work really hard to achieve this mini-goal, but I need some help to figure out how exactly to do it.

Is there some formula that would approximate the number of calories I'd need to burn over a three day period to achieve a fat loss of 800g?
