Success though weight loss statistics...

Having read this interesting link:

I thought I’d look at my weight loss statistics spreadsheet….

Ok, some confessions, I’m at accountant and I like spreadsheets. I’m a bit obsessed by my diet and weight myself every day. Sometimes more.

I have tanita body fat scales and have logged the weekly weight plus monthly weight, bodyfat and body measurements.

In October I weighed 173lbs, this was post pregnancy and breastfeeding. I have now lost 54lbs. I started off doing general low calorie but I switched to low carb (although not a ketosis diet) whilst still monitoring calories in month 5.

Before: 173lbs, BMI 30, Body Fat 40%, Hips 43 inches, waist 36 inches
Now: 119lbs, BMI 20, Body Fat 19%, Hips 34 inches, waist 26 inches

After reading that article I thought that I’d look at my figures!

In the first 4 months of my diet, although it was reasonably healthy (1400 calories, plus exercise cals of which I ate at least half) I was eating cereal for breakfast, sandwiches for lunch, and daily snacks including chocolate (as part of calorie allowance). I was doing mainly cardio training as I was working towards a triathlon.

In month 5 I switched to a high protein diet (initially dukan) and although I am not strictly following dukan anymore, I still eat lean protein at each meal and always overshoot what MFP suggests on protein and always undershoot on carbs. I now eat minimal processed foods, and I just cut out diet drinks (but only in last month).

In month 6 I had 2 weeks off my diet as I was on holiday and when I came back I started doing more resistance training.

What the figures below tell me (see %fat loss column) is that a normal healthy iet with mainly cardio training can result in a loss of lean muscle as well as fat (although I guess that some of initial loss will be water).

But add lean protein and resistance training into the mix and muscle mass can be preserved (or maintained).
