It's not that hard to lose a stone. I've recently achieved this by doing the following:
- Started going to the gym about 6 weeks ago, for the first time ever. I do 6 to 8 hours a week, split 2:3 between strength training and cardio. Nothing too extreme, but I always push myself and make sure I'm sweating like crazy by the end of a gym session. It was actually pretty painful in the first two weeks and quite a struggle to convince myself, but once you get over that hill, it becomes a routine and you just go whether you like it or not. Hard to put it into words, but I now get this odd feeling of guilt if I break my routine so I just go, even if I'm tired and not feeling up to it.
- Changed my diet considerably. Much more fruits, veg and fibre based food, more protein and healthy fats. I thought this would be difficult, but it's actually pretty cool once you discover some of the healthy options out there and even the stuff that tasted bland before, now tastes pretty ... err tasty. You just get used to it. Main thing is you need to replace sugars/carbs with protein heavy food, along with lots of fibre, unsaturated fats and water. I've pretty much cut out all junk food, but still enjoy it once a fortnight or so. If you're dying from hunger, grab a banana, I love these things.
A single stone doesn't sound like much, but considering that I was doing little or no strenous activity and eating garbage for the last decade or so, I think it's a good result, plus it's only going to get better. For me though, the biggest difference is that I actually feel more 'healthy'. My resting pulse has plummeted and I simply feel more awake and lively than ever before.
Seriously, it's the one the best things you can ever do and apart from the things I mentioned above, I do everything else the same as before.
