Have you ever wondered what a British grandmother and a 22-year-old dieter have in common? They both take supplements to help promote weight loss. Though the latter is probably in full knowledge of what he or she is doing, the former may have no idea that a daily cup of tea is doing wonders for her waistline.
Taiwanese scientists show that habitual tea drinkers carry less total body fat and concentrated abdominal fat than their non-tea-drinking counterparts. This is due to the catechins found in tea. These enzymes kickstart the body into pushing energy sources into the bloodstream rather than storing them to eventually convert into fat cells. Green tea is found to have the highest concentration of catechins, but regular consumption of plain black tea is also found to have similar effects. Before you race down to the store to buy pounds of English Breakfast, there is no evidence to show that crash dieting on tea will have any effect on your waistline. But after gradual, continual drinking of tea, in conjunction with regular exercise and sensible eating, a difference should be noticeable.
Studies conducted at the Ben May Institute for Cancer Research at the University of Chicago found that when catechin was given to rats, their appetite was decreased and they lost body weight. It also affected their metabolic rate. The rats had a higher heart rate when resting, which led to them achieving the optimum heart rate for weight loss faster when exercising. When tested on humans, similar results were noted. When taking catechin supplements, in the form of green tea prior to exercise, most had a higher Resting Metabolic Rate (RMR) prior to starting their workout. This led to faster, more sustained time in the fat burning heart rate zone. A higher RMR has the added bonus to continual fat burning after the workout is complete. Those taking catechin and exercising in the morning felt more energized and believed their bodies to be working more effectively than prior to introducing catechin into their diet.
The researchers at the Ben May Institute also recorded that the rats sex-linked hormones were also affected by the catechin. It led to blood flow being more stable than the rats that were not being supplemented with the enzyme. It was documented that the adrenal glands were producing more testosterone — the main hormonal sexual stimulus. Those partaking in the human trials noted that after a sustained period of having catechin in their systems, they felt more relaxed and less anxious in their relationships.
Though the many benefits of catechins in tea are plain to see, it also important to be aware that increases in this enzyme may not be a wise decision for all. For those undergoing intense physical exercise regimes, catechins may alter the metabolic and hormonal levels to a point that could become detrimental to their current routine. As with any significant dietary change, if you think that it will negatively affect you in any way, consult a healthcare professional.
So the next time someone asks what do you and a British grandmother have in common, what are you going to say? By inheriting the cup-a-day tea routine, you can smile and answer that you are both drinking your way to a slimmer, healthier, calmer new you.
