I'm not set against these treatments, although am in favour of their regulation, and have seen some really good results in people I know. However I think the high demand for these procedures does reflect our slightly imbalanced relationship with our bodies.
The media encourages us all to be vain/neurotic about our appearances to the point where we don't want to show any signs of ageing or even a spare (and healthy) extra pound. So people are eager to turn to quick fixes such as fillers or liposuction to sort these 'imperfections'. But we're missing the point if we think this is the answer.
How we look on the outside tells us an awful lot about what's going on on the inside and these are messages we should pay attention to.
If your skin is wrinkling or thinning prematurely then it's not just your skin that's ageing - it's all your internal cells too, which means that your organs are also wearing out too fast. Rather than getting some botox the answer should be to follow an anti-ageing diet (low sugar, high efas + fruit + veg, lots of water and sleep).
Not only will this extend your life but you can use this as a barometer of how effective your dietary changes are - as your skin starts to glow and look plumper and younger you'll know you're having a positive impact from the inside out.
The same applies to weight, stubborn weight around your middle is a big flag for potential insulin resistance/diabetes and/or adrenal and thyroid issues. A bit of lipo will not fix any of these underlying issues that could be highly debilitating in the long-run.
A low GI, high fibre detox diet would not only help shift your love handles, but also help regulate your blood sugar and reduce stress on your endocrine and cardiovascular systems.
If we all spent a bit more time focussing on what's going on on the inside we'd actually all end up looking and feeling a lot younger and not needing these quick fixes.
