Humans were never subject to constant and abundant food supply in the history preceding the agricultural revolution around 80 years ago. Before this, there were intermittent forces of nature causing food to become scarce for periods of time. The people who survived these eras passed on their advantageous genes. During periods of fasting, the brain actually releases more human growth hormone (HGH) which helps preserve lean muscle mass in men and women (8). A study done in 1992 on 9 men showed that HGH production rate increases 5-fold after a 2 day fast (9). So fasting can essentially cause increased fat loss while preserving your muscle mass. It’s for this reason that many athletes are now adopting fasting into their training routines (10).
Blend a banana, strawberries, and blueberries into a frothy smoothie, and you’ve got a delicious drink. Make your own, so you can control the ingredients: skim milk (or an alternative, like almond milk) and fresh or frozen fruit are all you need. Restaurant smoothies may include ice cream, honey, or other sweeteners that boost the calorie count sky-high.
A mere five years ago, skipping meals was a top diet taboo. Now it's the core of an increasingly popular (and increasingly research-backed) weight-loss approach. Intermittent fasting—periodically eating very little—is not only not bad for you, it may lower blood glucose levels and insulin resistance and reduce inflammation and cardiovascular risk. Why? How? Theories abound, but some experts believe fasting puts your cells under mild stress, just as exercise taxes your muscles and heart, ultimately strengthening them and making them more resistant to disease.
This is similar to the stress your body undergoes when you hit the gym. While exercising, that is a form of stress your body endures. As long as you give your body enough time to recover afterward, it will do your body good. The same applies for intermittent fasting — as long as continue to alternate between regular eating habits and fasting, it will continue to benefit you[*].
We all know how important it is to drink enough water — it restores fluids lost through breathing, exercising and metabolism. It’s the number 1 thirst quencher … and cheap! But the timing could make a difference, too. When you start to feel hungry, drink some water. A 2015 study in the journal Obesity found that participants who drank about 2 glasses of water before meals were more likely to lose weight than those who skipped the glasses of water and went straight to eating.
Pomegranate contains vitamins C and K, folate, proteins, fiber, and potassium. Punicalagins present in pomegranate are antioxidants and help boost the overall immunity. Pomegranate prevents type II diabetes, cancer (prostate and breast), and heart disease. It is also beneficial for those who have arthritis, blood pressure, skin diseases, and cognitive disorders. It improves memory and blood circulation (19).
What makes Runa Clean Energy special is guayusa, a plant native to the Amazon rainforest with double the antioxidant capacity as green tea, according to a report in the Journal of Ethnopharmacology. Legend has it, indigenous hunters nicknamed the leaf “night watchman” for its ability to heighten awareness and prevent sleep. With as much caffeine as coffee, guayusa is also a rich source of theanine, an amino acid that researchers say can work in synergy with caffeine to calm and focus the brain.The result? A jolt of energy without the jitters. In other words: clean energy.
Why try a plan with a high dropout rate and hours of hunger? Beyond the health benefits, some people actually like it—and find it the easiest way to control their weight. Mark Mattson, Ph.D., a neuroscientist at the National Institute on Aging, has studied intermittent fasting since the 1990s and himself been on a plan for years. "Once you get used to it, it's not a big deal," he says. "You adapt." Other fans? Reportedly, trendsters from Beyonce to Silicon Valley techies; and Jimmy Kimmel has said he lost 25 pounds fasting too. So... should you experiment?
Intermittent fasting has been shown to increase fat loss while maintaining lean muscle mass. In one four-week study, researchers concluded that a fasting diet resulted in greater weight loss — while maintaining muscle mass — than participants following a low-calorie diet. This happened even though the total calorie intake over the four weeks was similar in both groups[*].

Fasting as a spiritual practice has a long history in many religions. The idea of purification and cleansing as a way to create change may help increase motivation for weight loss, and brief use of a homemade cleanse may help break habits of overeating and reduce the appetite. For a homemade cleanse to be useful as a means to jump-start weight-loss, it's important to follow the cleanse with lifestyle improvements. A healthy, balanced diet and exercise program provide the most effective means to safely achieve your weight-loss goals. Consult your doctor before attempting a cleanse or fast.
Even if you manage to meet your goal, it probably won’t be sustainable: “The amount of restriction required will make you so hungry that you’ll eat everything in sight—it’s survival instinct,” Dr. Seltzer says. What’s more, your body will be less prepared to burn the foods you binge on, since calorie restriction gradually slows your metabolism, he adds.
That’s in part because when you restrict calories, you restrict nutrients. As a result, you lose weight on a crash diet, but much of it is lean, healthy muscle tissue. With less muscle, your body’s metabolism is set at a lower point. So when you go off the diet, even if you eat the exact same number of daily calories as you ate before, you’ll actually gain more fat than you originally carried.
