A systematic review of 40 studies found that intermittent fasting was effective for weight loss, with a typical loss of 7-11 pounds over 10 weeks.  There was much variability in the studies, ranging in size from 4 to 334 subjects, and followed from 2 to 104 weeks. It is important to note that different study designs and methods of intermittent fasting were used, and participant characteristics differed (lean vs. obese). Half of the studies were controlled trials comparing the fasting group to a comparison group and/or a control group (either continuous calorie restriction or usual lifestyle), with the other half examining an intermittent fasting group alone. A brief summary of their findings:
Kiwi detox water belongs to a league of its own. This exotic fruit is blessed with tons of dietary fiber, which helps it remove extra sodium from the system. Girls who consume too much salt may discover a lot of assistance through these tropical treats. Huge vitamin C reserves make this special water a formidable detox agent. Strawberries fight free radicals with antioxidants of their own. This is a quick fix for potassium deficiencies. These brews are notably easy to prepare, and the ensuing metamorphosis is disproportionately positive when compared to the amount of effort required.

My own research found that people following a very-low calorie diet (550 kcal) experienced reduced levels of the “hunger” hormone ghrelin the following day. As high concentrations of ghrelin are associated with feeling hungry, lower concentrations of it after a very-low calorie diet suppress appetite, and could help people with short-term weight loss.
Rooibos tea is made from the leaves of the “red bush” plant, grown exclusively in the small Cederberg region of South Africa, near Cape Town. What makes rooibos tea particularly good for your belly is a unique and powerful flavonoid called Aspalathin. According to South African researchers, polyphenols and flavonoids found in the plant inhibits adipogenesis–the formation of new fat cells–by as much as 22 percent. The chemicals also help aid fat metabolism. Plus, Rooibos is naturally sweet, so you won’t need to add sugar. It’s also not technically a tea—it’s an herbal infusion.

"The term 'detox' has become a buzzword that is often misused by the media and consumers," says Jackie Armstrong, MPH, RDN, EP-C. Jackie is a Performance & Wellness Nutritionist at Stanford University and the founder of Well-Fueled.com. She says that detox diets are often misunderstood. "Our organs and tissues are constantly in a state of detoxification — getting rid of unwanted substances produced by the body or from our environment." She goes on to explain that research is lacking to support the effectiveness of most detox diets.
