Google "how we get fat" and "Lyle Mcdonald". How we get fat is a very interesting article. No need to fear carbs. I don't think most of us here are eating enough of them to worry.
1) Carbs are rarely converted to fat and stored as such
2) When you eat more carbs you burn more carbs and less fat; eat less carbs and you burn less carbs and more fat
3) Protein is basically never going to be converted to fat and stored as such
4) When you eat more protein, you burn more protein (and by extension, less carbs and less fat); eat less protein and you burn less protein (and by extension, more carbs and more fat)
5) Ingested dietary fat is primarily stored, eating more of it doesnâ??t impact on fat oxidation to a significant degree
Carbohydrates are rarely converted to fat (a process called de novo lipogenesis) under normal dietary conditions. There are exceptions when this occurs. One is with massive chronic overfeeding of carbs. Iâ??m talking 700-900 grams of carbs per day for multiple days. Under those conditions, carbs max out glycogen stores, are in excess of total daily energy requirements and you see the conversion of carbohydrate to fat for storage. But this is not a normal dietary situation for most people.
-> Excess dietary fat is directly stored as fat
-> Excess dietary carbs increases carb oxidation, impairing fat oxidation; more of your daily fat intake is stored as fat
-> Excess dietary protein increases protein oxidation, impairing fat oxidation; more of your daily fat intake is stored as fat
All three situations make you fat, just through different mechanisms. Fat is directly stored and carbs and protein cause you to store the fat youâ??re eating by decreasing fat oxidation.
