I had a 200mg caffeine tablet 30 mins before an hour long run. I don't normally drink much coffee (1 espresso / work day), a bit more tea, perhaps 4 - 5 cups / day. Not long into my run I felt like superman. That was a Sunday morning. I then couldn't sleep most of the night and work was grim the next day.
I decided to leave the caffeine pills alone but to try a few espressos prior to a run. I just poured a normal size cup of it from the coffee maker (that has no measurement thing) and assumed it would about right. Again, I felt like super man and while not even aiming for it broke a recent 5K and 10K time while on a long-ish run (i.e. not meant to be at full pelt). On getting home I poured the rest of the espresso out of the maker... there was only about 1 espresso worth left and the thing makes 9! So 8 espressos prior to a run. I don't recommend this as, again, I couldn't sleep properly that night even though my run was at about 8:30am.
I've been trying a spot of caffeine to burn some fat. Sure, it gives a boost if you're not use to it but I think I'd give it a miss if I didn't have a need to burn that fat because the next day can be horrible.
Well, I have now just come off the phone from speaking to my doctor and I think that it was a very worthwhile conversation. The posts from people have also been useful because it prompted me to ask if the lump is in a sac, as Screamapillar thought. Screamapillar is correct, it is in a thin membrane "capsule". I also got the name of the thing, it is a "lipoma". I also asked about how the body triggers the breakdown of fat and if it would affect the lump. The doctor said that he was not aware of any papers on this but that, based on body chemistry and the biology of the lipoma, added fat burning will result in an increased amount being taken from the lump.
So, increasing fat burning will help after all.
I accept that the lipoma is never going away without surgery, however, given the risks I want to put that off as long as I can. If I get it to shrink and then stop my activity then the lump will grow again. At some stage of life I expect it will be hard to maintain sufficient activity but that should be a long way off.
Now what I want to know is what will make enough difference. I expect that the equation is something along the lines that the faster the lump grows normally the faster it can be made to shrink because the chemical signalling breakdown of fat will arrive more freely (than if the thing is slow growing). This has upsides and downsides. I expect it will be a lot of effort regardless. It will be less effort if the lump is fast growing but then if I have an injury I'll have more to catch up on later.
The doctor is going to run off the report from my first MRI so I have the dimension to compare. Of course, I will have to stump up for another MRI if I want to establish progress... and I will probably need to do an MRI shortly and then another after an extended fat burn "plan" to see if what I'm doing is having any effect. Not sure if I can afford it yet, (quote request has gone out). Anyone got a handy MRI scanner ?
I saw the specialist several times when the lump was first spotted. This was over a short period while they sent me for various tests ending up with an MRI that I was told established the lump was made of fat and that it came with the awkward treatment issues mentioned (nerve pathways and artery) plus worse odds than Russian roulette.
The specialist said that the lump would continue to grow and that at some point it would probably cause problems for me. He suggested what sounds like trivial things such as soreness shaving, (and the social/cosmetic aspect too of having a clearly visible thing on my neck). He said he would leave it to me to decided if/when to operate. That was sometime in 2014 I think.
Reading running books over the Christmas break that talk about how you can train to burn fat in preference to carbs left me thinking that perhaps something like that might help. I have Googled it but not come across anything factual or especially useful.
Screamapillar guesses that the tissue is contained in a sac. I didn't know that was how they tend to form. I still presume that to get fat in there, sac or not, it still takes blood to transport it to the site. The same blood that transports fat away from other sites as it breaks down.
You are all probably right. But I see no harm in finding out for sure and I assume that the posts above are opinion so, although I am listening to you, I will try to find out something concrete.
