Made from pulverized green tea leaves, you stir matcha into hot water. Therefore, you consume the whole tea leaf. For that reason, you get a bigger dose of ECGC. One study from the University of Colorado at Colorado Springs compared the two and found that drinking matcha delivered 137 times the metabolism-revving ECGC compared to traditional green tea. One tip: if you find matcha to be too bitter on its own, foam it into milk and stir with honey for a delicious matcha latte. (If you need some more convincing, here’s some more information on how incredible matcha is as a weight-loss tea.)
Also known as branch chain amino acids. BCAAs are three amino acids known as Leucine, Valine and Iso-Leucine. They help prevent muscle breakdown and can be bought as yummy flavoured powders to use in place as sports drinks. Drink them during your workout instead of water as they will help you tone up as you lose that belly and may even help in the formation of abdominal muscle.
Intermittent fasting is a diet regimen that cycles between brief periods of fasting, with either no food or significant calorie reduction, and periods of unrestricted eating. It is promoted to change body composition through loss of fat mass and weight, and to improve markers of health that are associated with disease such as blood pressure and cholesterol levels. Its roots derive from traditional fasting, a universal ritual used for health or spiritual benefit as described in early texts by Socrates, Plato, and religious groups.  Fasting typically entails a steady abstinence of food and beverages, ranging from 12 hours to one month. It may require complete abstinence, or allow a reduced amount of food and beverages.
The smart money says my weight story ends badly. First, generally, there are lots of people who lose lots of weight, and almost all of them gain at least most of it back, and disturbingly many end up gaining more than all of it back. Some people do lose lots of weight and then keep it off permanently (well, you know, in the sense that anything in this life can be permanent), and the number of such successes seems to be increasing over time, but to succeed in keeping significant amounts of weight off is still very much to be an outlier. Second, I in particular have lost a significant amount of weight in the past, only to gain it all back and then some.
Whether a regimen calls for two fasting days a week or eating your meals in a smaller "window" of time in the day, all plans share a near-freedom from calorie counting, a big plus for weary food diarists. Once you have planned your fasting-period menu—say, a 500-calorie day of chicken and veggies—you're set. And in your nonfasting periods, you eat normal, healthy meals (even that steak!) without worrying about every bite.
Oolong tea is rumored to have some weight-loss benefits, but Ansel says there hasn’t been much evidence to back this up. One study published in the American Journal of Clinical Nutrition in 2013 found that oolong and other teas didn’t have a clinically meaningful outcome on weight loss. As for roobois tea, Ansel says it hasn’t been studied as much as other varieties, "but there’s no convincing evidence that it has any real impact on appetite.”
Intermittent fasting — the most popular form of fasting today — consists of eating within a specific window of time in the day, and not eating for the remaining hours of the day. For example, one popular version of intermittent fasting is the 16/8 method. This entails a nonfasting window of eight hours (such as 11am to 7pm) followed by a fasting period.
