Today is the first weigh-in. I must admit to being tempted to cheat and weigh myself wearing less clothing than last week, or to try to stand lightly on the scales so that I’d have lost some weight. In the end, I just didn’t need to do any of that.
I’ve lost a whacking 8lbs or 3.5kg and I must admit to being completely shocked and surprised.
I know nay-sayers will say that you always lose more on the first week of a diet, due to your body getting used to it, but I’ve tried “diets” before, and I’ve lost maybe 1-2 lbs per week. This level of loss is unprecedented for me.
I thought I must therefore be eating far less calories than normal over the week, but that simply isn’t true.
To paraphrase a recent advert… Here comes the science bit!
- If I use MFP to lose weight, which I have done previously, it tells me that I need to eat about 1300 calories per day (based on a sedentary lifestyle in the office). Probably if I log all the walking round the office that I do, I would say that I use up maybe 200-300 calories, so if I’m strict then I’d be eating about 1500 calories per day. Over the week, that’s 10500 calories which gives me the 1-2lb weight loss and I probably do try to get under the calorie level, so between 10000-11000 would be a realistic week’s eating.
- Under the 5:2 diet, I’m eating 2 days of 500 calories, and then 5 days of 1861 (and I do try to maintain that level, maybe only dropping 30-40 per day) which totals 10305 calories. So I’m probably eating about the same value of calories, but I’m losing far more weight.
I’m almost tempted to try another fast day today to see if the loss can continue, but on balance, I think I’ll let my body just eat normally. I’d like this to become a way of life, not a quick fix which is soon forgotten. I know my body can do the eating plan, so if I stall over a couple of weeks, then I’ll maybe think about going 4:3 for a few weeks to kick things up a gear. For now though, 8lbs will do me just nicely!
