    1. 1. Green Tea<br />
    2. 2. What is green tea?<br />
    3. 3. Camalliasinensis<br />“Green tea” is produced from the plant Camellia sinensis, whose leaves and leaf buds are used to produce Chinese tea.¹<br />
    4. 4. Green tea is fresh<br />Because green tea is fresher and not allowed to wilt or oxidize, it has slightly higher antioxidant content than other teas.<br />
    5. 5. The whole world is drinking it<br />Tea is the most popular drink in the world in terms of consumption.<br />China, India, and Kenya are the 3 major producers (10)<br />Russia, the UK, The United Arab Emirates, and the USA are the biggest importers of tea. (11)<br />
    6. 6. So what does green tea DO?<br />A lot, apparently!<br />
    7. 7. Really? Just tea?<br />^images of people endorsing green tea diet<br />
    8. 8. Well, maybe!<br />Certain properties of green tea could aid in weight loss.<br />However, few studies look at green tea and weight loss in the long-term<br />
    9. 9. How does one lose weight?<br />
    10. 10. How does one lose weight?<br />Reduced caloric intake + enjoyable physical exercise = the body tapping into its fat reserves for fuel.<br />Calories consumed < Calories burned<br />Reduce calorie consumption by 15% at most<br />More lean body tissue = higher metabolic rate<br />Metabolic rate: Calories spent purely on body maintenance<br />Make more lean tissue through strength training!²<br />
    11. 11. Where does tea fit into all of this?<br />Green tea has been shown to provide a modest boost to metabolism³.<br />Metabolism<br />boost!<br />
    12. 12. Dulloo, et. all <br />A Swiss research team found that 270 mg of green tea extract (50mg caffeine, 90mg EGCG) 3X a day alone with no exercise increased metabolic rate by the equivalent of about 79 calories/day on average<br />
    13. 13. Maki, et. all.<br />In another study, participants who drank green tea and engaged in ≥180 minutes per week of moderate intensity exercise for 12 weeks saw a greater reduction in subcutaneous abdominal fat and lower levels of serum triglycerides compared to participants exercising and not drinking green tea <br />
    14. 14. What’s the secret?Antioxidants!<br />Catechins<br />EGCG is the most abundant.<br />Shown to stimulate the body to burn fat<br />
    15. 15. EGCGBose, et. all.<br />Mice receiving the EGCG experienced reduced body weight gain, liver weight, blood glucose levels, percent body fat, liver triglycerides, and cholesterol levels<br />Another short-term study showed that mice given EGCG appeared to not only have less fat absorption, but experienced a reversal of symptoms associated with metabolic syndrome (6)<br />
    16. 16. The big connection<br />“Oxidative stress” theory<br />“Free radicals”<br />Radicals are believed to be involved in degenerative diseases, cancers, and endothelial disruptions that lead to diabetes and obesity.<br />Antioxidants terminate oxidation by being oxidized themselves, and inhibiting other oxidation reactions, including reactions that liberate fat from the diet into the bloodstream <br />
    17. 17. Well that’s nice<br />But does it “work?”<br />Will green tea make me lose weight?<br />Funny video time!<br />
    18. 18. You have an ally in green tea<br />Green tea gives you a 75 kcal/day boost.<br />75 kcal/day = 1 lb of fat loss every 44 days<br />Lose 8 -9 lbs / year on tea alone!<br />
    19. 19. Too much?<br />Too much tea has health consequences<br />Caffeine<br />Green tea contains 20%-60% of the caffeine in a cup of coffee<br />Caffeine in excess can produce heart palpitations, irritability, anxiety, insomnia, heartburn, and peptic ulcers among other things.<br />
    20. 20. Green tea and Pregnancy<br />EGCH can inhibit an enzyme called dihydrofolatereductase (DHFR) (9)<br />Also known as vitamin B12 or folic acid<br />Can induce folic acid deficiency, causing abnormal neural tube development. <br />When the neural tube of an embryo fails to close completely, spina bifida may result<br />
    21. 21. Pregnancy and Caffeine<br />Caffeine is a stimulant and a diuretic.<br />Because caffeine is a stimulant, it increases your blood pressure and heart rate, both of which are not recommended during pregnancy.<br />Caffeine also increases the frequency of urination. This causes reduction in your body fluid levels and can lead to dehydration. <br />
    22. 22. Everything in moderation<br />Be realistic about fitness goals<br />Drink tea for the antioxidants and health benefits<br />Green tea can:<br />Reduce triglyceride levels<br />Reduce glucose levels<br />Reduce abdominal fat content (6)<br />
    23. 23. Group Endorsement?<br />Angela: “I drink green tea all the time.”<br />Rebecca: “Drink it. Love it.”<br />Brandon: “SLAM IT.”<br />Phu: “Living proof.”<br />Zachary: “It works.”<br />
    24. 24. Where can I get tea?<br />Washington Tea Rooms<br />
