Other intermittent fasting diets take a different approach. The 5:2 method, for example, requires you to eat as you normally would for five days a week, but on two nonconsecutive days, you eat just one meal a day. Wright says she spent five months conditioning her body to the 16:8 method. At that point, she says, she switched to the 20:4 method. According to this method, you fast for 20 hours and have a 4-hour eating window.
Ditch the packaged, processed foods today (even the “healthy” versions). This will ensure you are taking out excess sodium, artificial ingredients and sugar from your diet. Also, ditch the salt shaker and instead use only herbs and spices to flavor your food. You’ll find this can help make a big difference in how you look and feel. Even after one day!

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[*].
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.
While Samantha seems to attribute much of her success to the healthy drink, Katherine Zeratsky, R.D.N., L.D., an instructor of nutrition at Mayo Clinic, says that lowering her calorie intake was probably the biggest factor in Samantha's weight loss journey. Although caffeine in green tea can jump-start your metabolism, it wouldn't be enough to produce significant weight loss results, says Zeratsky.
Long term fasting is said to be bad for the body and weight loss both. However, short term fasting like the one followed in intermittent fasting is said to promote fat burn and even boost metabolism, leading to weight loss. Studies have shown that short term fasts of upto 48 hours can have positive and desired results on the body. This happens because the period of fasting results in several changes in the levels of various key hormones in the body- insulin, growth hormone and norepinephrine. During the period of abstinence or fast, the levels of insulin go down while those of growth hormone increase, both resulting in fat burn. Additionally, norepinephrine or noradrenaline is sent to the fat cells, breaking them down in fatty acids, which can be directly burned for energy. Moreover, because dieters are restricting the hours of their food consumption, they're automatically consuming lesser amount of calories than before. This is another reason intermittent fasting may lead to weight loss.
And Ian K. Smith, M.D. agrees. Dr. Ian is a Harvard graduate, founder of the SHRED Lifestyle, and the author several best-selling diet books. He explains that the liver, kidney, lungs, skin, and gastrointestinal system remove toxins that accumulate in the body. But following a detox diet full of natural foods can enhance the body's ability to cleanse. He adds, however, that dieters should make no assumptions about health when choosing a detox diet. "Detoxes have gotten very trendy, and many of them are unhealthy and quite dangerous."
