I got a note recently from a reader asking about Wu-Yi Tea:

“What’s up with this Wu-Yi Tea?  I see it everywhere online!  Does it work?”

Wu-Yi tea is the same as another tea on the market, Wu-Long…which is a marketing spin on the word Oolong, a tea that you have probably heard of before.  The claims made by these teas are based on one Japanese study where energy expenditure was measured for 120 minutes after consumption of both oolong and green teas.  Oolong increased energy expenditure in the subjects by 10% as opposed to 4% for the green tea.

However, there are two major flaws in this study:

• 120 minutes is not a significant amount of time

• There was no measurement of fat loss specifically

So there may be some benefit to consuming oolong tea, but it would require several more controlled studies before I would recommend it as a supplement you should include in your arsenal.

Also, oolong tea is widely available in supermarkets and specialty stores – so if you choose to use oolong tea, you don’t have to pay the outrageous prices they are charging online.

Last time we talked about the Thermic Effect of Feeding (TEF) and its role in burning fat. TEF can represent as much as 10% of the calories burned in a day. So how do you burn the other 90%?

Physical activity can represent 20-30% of your daily energy expenditure – this is comprised of your normal physical activity (for example, lifting the kids or groceries, washing the car, walking, etc.).

So that leaves 60-70% of your daily energy expenditure coming from – get this – DOING NOTHING! That’s right, sitting around watching TV, sleeping, etc. Your Resting Metabolic Rate (RMR) is where most of your calorie burn comes from! When you hear people blame a “slow metabolism” for being fat, they are partially right – their RMR is not what it should be to burn the amount of calories they consume!

So, last time we learned that eating more frequently increases your TEF, but how do you increase your RMR, which is REALLY going to get the fat burning?

It’s really simple – the more muscle you have, the higher your RMR will be. When you workout, you are breaking down muscle fibers.  The process of rebuilding that muscle is intense – it requires rest and protein, and subsequently raises your metabolic rate. Once you have built the muscle, it will keep your RMR elevated as it takes a lot of the body’s effort to maintain it.

Also, the high intensity intervals, the cardio where you do all-out bursts for a short period of time followed by recovery, creates the
same demand on your metabolism as resistance training. If you choose to do cardio, this is the kind of cardio you should be doing.

So to wrap this up, science tells us these things are the most effective things you can do to lose fat:

1. Eating more often (shooting for 6 small meals per day)
2. Resistance training
3. Interval cardio

There are two more things to add to this list that I’ll cover next time.
