This being the Low Carb Forum on the website, I figured that people posting here would be doing some variant of LCHF, Atkins, Paleo or Primal.
If you are reducing carbs but not upping fat, that may work for awhile as you lose weight. What happens when the body decides it has reached optimal weight, which fuel will it use then, if not it's own excess fat ?
If you aren't eating fat to compensate for the lack of carbs, it's likely that weight loss is because of a calorie deficit. The brain could start thinking that this is starvation, and rebound after the weight loss just like with any other calorie-controlled diet. (Escape the Diet Trap by Dr John Briffa is an excellent book on this).
Conversely, nuts are high in fat but also really high in protein. Excess protein can be laid down as fat.
My guess is, that our body is adapted to utilise whichever handy fuel source is easiest and whichever uses the least energy to make. If it uses the glucose in a high carb diet, it will probably use he fat in a high fat diet. Maybe both of these are easier for the body than converting body fat.
As long as I'm not obese, I'm happy with stable weight. Recently, I quit whole milk because compared to cream or creme fraiche it seemed thin. I just wasn't enjoying it, even though it was organic whole pasteurized but unhomogenised milk straight from a farm. To compensate for the loss of milk, I upped other forms of dairy, which are lower on the Insulin Index.
Instead of putting on weight I lost it. In fact, because I don't weigh myself, to find that my new trousers became baggy two weeks after buying them, was quite disconcerting.
I seriously doubt that members are eating very low carb also. I eat around 25-30g carb a day, usually only from veg and dairy.
Professor Tom Noakes believes that to prevent diabetes deteriorating, it necessitates eating 25g carbs per less or day. Dr Eric Westman MD keeps obese patients at his clinic on 20g carbs per day, for as long as necessary.
The point of this thread however, was to discover which fats and oils other members use. I haven't eaten much tinned oily fish, which is something I can do and my husband is the nut fiend, so again I could try those.
So thanks for the ideas !
