This study essentially confirms a well-understood weight loss principle: whatever method you use, in order to lose weight you must reduce your total calorie intake. The 5:2 diet is designed specifically to reduce your total weekly calorie intake by a similar amount as a daily calorie restriction diet. So perhaps its not too surprising that end results are similar.
It seems intermittent fasting can help your mind as well as your body. Fasting has been shown to help improve memory your memory, reduce oxidative stress, and preserve learning function[*]. Some researchers believe that because humans went thousands of years where food was not readily available, they adapted to function at a high-level (both mentally and physically) while in a food-deprived state[*].
According to a new study in the European Journal of Nutrition, both black and green tea are active in aiding weight loss. The University of California researchers found that decaffeinated green and black tea have a positive impact on decreasing the bacteria in our gut, which is closely tied to obesity. These teas target the good bacteria in our bodies that create lean body mass—aka they're serious fat burners.
While going entire days without food may seem to go against everything you’ve been taught about health and nutrition, some studies there are no adverse mental or physical effects through fasting[*]. Depending upon the approach you take, you may find that a prolonged fast can become quite uncomfortable. For example, when studying individuals taking various approaches to intermittent fasting, the NIH found those who attempted alternate-day fasting reported great feelings of hunger. More so, those who tried the alternate-day fasting method did not lose significantly more weight than other groups[*].
The problem with fasting is that due to severe calorie restriction, your basal metabolic rate (BMR) will decrease. It is thought that fasting can decrease the body’s metabolism by up to 22%. This means that your metabolism will slow down and theoretically, if you were to eat the same amount of calories you did before you started fasting, immediately on the stopping the fast, you would put on weight – not “water weight”, but fat. If this were to happen, you would end up with a higher body fat percentage than when you started.
Oolong tea is also obtained from Camellia sinensis, but the processing is different from green and matcha teas. It is also loaded with EGCG, a potent phytonutrient that has antioxidant properties. Scientists have confirmed that oolong tea is great for weight loss as it helps lower the lipid levels in the blood and increases fat metabolism (24), (25).
This recent study was conducted over a 50-week period, making it one of the longest intermittent fasting studies to date. Researchers split 150 participants into three groups. One group followed the 5:2 intermittent fasting diet (with two non-consecutive “fast” days per week eating about 500 kcal), while the second group reduced daily calorie intake by approximately 20%. A third control group weren’t instructed to change their diet.
“For three years while I was in high school, my parents took us to live near relatives in Argentina, where yerba mate is part of the cultural tradition, kind of like coffee is for Americans,” she explains. “I remember that the younger people realized drinking yerba mate made us eat less and lose weight. We purposely drank lots of it to keep nice and trim. It wasn’t anything scientific back then, just teenage girls wanting to look good. But when I remembered that, I did some research.” What she found inspired her to begin drinking two to three cups of the spicy herbal brew a day. And those cups of tea prompted her incredibly effortless weight loss.
Moreover, the ritual involved in making tea (as opposed to shoving coins into a vending machine) gives you a welcome break from your chores or work -- and you can reflect on good thoughts, as well as making conscious choices to put good things into your body instead of empty calories from candy bars. Take a moment to chat to someone else who is in the tearoom with you. And it's a great way to unwind, stretch and socialize in the space of five minutes!
