Have you been told your metabolism is slow? Have you heard of different "tricks" for jump starting your metabolism? Do they really work? Are they even true? There really is no such thing as a "slow metabolism" in regard to the way most people refer to it in regard tio weight. While there are some medical conditions (thyroid) that can effect metabolism & weight, these are easily tested for and rectified.
Part of the confusion is due to a misunderstanding of metabolism & what people mean when they discuss it.
Total Energy Expenditure (TEE) is the total amount of calories you burn in a day. Some people often confuse this with "metabolism" (RMR &/or BMR) but they are not the same. It is the sum total of your "metabolism", the thermal effect of food (TEF), and ones activities of daily living (ADL) & physical activity (PA).
Basal Metabolic Rate (BMR) is the amount of caloires you burn if you did absolutely nothing all day but laid in bed & slept.
Resting Metabolic Rate (RMR) is virtually the same thing as BMR & is often used interchangeably. It is slighlty different & is how many calories you burn if you were awake and did nothing but stayed in bed all day & rested. It is slightly higher than BMR as it includes some activity from being "awake"

HDL: More Than Just A Number |

The post on HDL and exercise was to point out the potential relationship and benefit between the two. However, lets look at the relevance of HDL in regard to the bigger picture.
The long lived Okinawans have a HDL in the 30s, and the "anti-atherogenic" diet of the Tarahumara Indians keeps their HDLs in the upper 20s. So, having a high HDL is not a prerequisite or a requirement for optimal heart health. Both of these groups have virtually no heart disease despite their low HDLs.
So, I think the focus on HDL is completely misguided. In my opinion, as long as someones total cholesterol, and their LDL are low, their HDL is really irrelevant. HDL has been thought of as the good cholesterol but as in everything there is more to the story. it is much more than just a number.
There are subfractions of HDL and some are thought of as being good, and some are thought of as being not so good. In recently published research on men in a three-week low fat program, blood tests showed that on entry the men (typical high-fat American-style eaters) had normal amounts of HDL, but the HDL tended to be pro-inflammatory. Pro-inflammatory HDL promotes plaque build-up in the arteries. |
