Well I weigh in the region of
100kgs, and would say at a conservative guess my bodyfat must be @ 30% mark.
I would like to loose the excess fat thru running and weight training not to be a bodybuilder, but to have a better body which in turn should help improve my health.
We could sit here all day outlining diet guidelines but as has been said it's all about finding a way of eating that suits you. My advice would to be lay off all processed/refined foods especially sugars and grains which promote insulin response and therefore body fat storage, processed vegetable fats are also best avoided.
Construct your diet from Unprocessed meats, fats, eggs, dairy products (preferably unpasteurised) fish, vegetables and salads, some fruit and nuts are ok but be sparing with the fruit as the fructose will also lead to an insulin response, Blueberries, raspberries, strawberries etc are a better choice than the usual apple, oranges, bananas that most people eat as they are much lower in sugar but are still very high in phytonutrients and anti-oxidants.
Keep your vegetable intake to the fibrous variety, eg those that grow above ground, root veg such as potato, carrots, parsnip are high in sugar and will encourage fat storage via the insulin response, you can eat them but don't go overboard, you could experiment with sweet potato as they have a lower glycemic index.
Again though, don't be afraid of the fat, much of the information out there regarding the potential health hazards of saturated fats is untrue, we have been mis-informed for years on this subject and it has encouraged un-natural low fat diet recommendations which has imo led to widespread obesity, a low fat diet has to by process of elimination become a high sugar/carb diet.
Do some research on saturated fats and the role they play within the body and like I did you'll eventually realise how important they are to us, it's difficult at first changing your mindset on this subject as it's such a deeply entrenched opinion that these fats are bad for us, in reality though nothing could be further from the truth, these fats play a vital role at the cellular level and are absolutely vital to our long term health and longevity.
When cutting carbs you have to replace the kcals with something and my advice would be to increase your fat intake markedly, don't avoid fatty meats and oily fish, a steak with a good marbling of fat is a much more balanced and healthy food than a fat free fillet steak for instance, it will provide you with good fat soluble vitamins A,D,E,K but just as importantly it will satisfy your hunger far more than the fat free fillet steak.
