So, the xmas break, which requires food and alcohol, along with a significant drop in exercise has resulted in what I would call a considerable gain of mass. I have written about mass loss before and I wrote more here also. To lose mass you have to burn more energy than you consume. It’s that simple [and no, you don’t have a gland problem!]. Not a lot else to it, it’s the psychology of it all that will fuck you over. I like eating and I comfort eat. It’s the self discipline that hurts. I know that when I am a healthy mass and exercise I can maintain that mass and still have blow-outs now and then.
So, before I get to my numbers, here are some facts about fat and exercise.
- One pound of fat is roughly 3500 kcalories.
- 10 metres walked or ran is roughly one kcalorie burnt.
- Daily intake for a man should roughly be 2500 kcalories.
So, my ideal mass would be <80Kg. However, I’ve not been that for a long time and I would be happy with <82.5Kg which comes in at 13 stone in old money. I am currently hovering around +90Kg. This upsets me greatly, but it is my own fault. Now is the time for action. Let’s just assume I want to lose 10Kg just to make the numbers easy. It’s worth knowing how long this will take and what effort I will face. I think many people are unrealistic about mass loss.
Some maths:
10Kg is approximately 22 pounds of fat to be lost.
22 pounds of fat is roughly 77 000 kcalories extra that needs to be burnt.
If I reduce my daily intake by 500 kcalories then this would take 22 weeks, as I would lose one pound per week. This is nearly half a year, which is a depressing amount of time to be on a restricted calorie diet.
If I maintain 2500 kcalories per day and run to burn the excess I will need to run 770 kilometres. Given that my average run is probably around 10km this means 77 runs. If I manage to run twice a week, on average, then this is over 35 weeks which is again an intolerable amount of time.
What I need to do is reduce my calorific intake while at the same time exercising to produce the desired results in a shorter (but sensible) length of time. I aim to be a healthy mass again by the end of March. This gives me three months or twelve weeks. I need to lose around 2 pounds per week. I can do it. I am determined to do it as some of the health issues that I have mentioned previously are back.
My progress isn’t going to be public. I am not going to start tweeting about this all the time. I probably won’t even mention it if I do or do not get down to the target mass.
