A randomized controlled trial that followed 100 obese individuals for one year did not find intermittent fasting to be more effective than daily calorie restriction.  For the 6-month weight loss phase, subjects were either placed on an alternating day fast (alternating days of one meal of 25% of baseline calories versus 125% of baseline calories divided over three meals) or daily calorie restriction (75% of baseline calories divided over three meals) following the American Heart Association guidelines. After 6 months, calorie levels were increased by 25% in both groups with a goal of weight maintenance. Participant characteristics of the groups were similar; mostly women and generally healthy. The trial examined weight changes, compliance rates, and cardiovascular risk factors. Their findings when comparing the two groups:
Mate tea is known for its powerful thermogenic effects—meaning it turns up your body’s calorie burning mechanism—and can also promote weight loss by improving insulin sensitivity. In a recent study, participants were divided into two groups. One group took a placebo 60 minutes prior to exercising, while the other group ingested 1000 mg capsule of yerba maté. Researchers found that those who consumed the herb increased the beneficial effects their workout had on their metabolism without the workout. Plus, this brew is like green tea on steroids, with up to 90 percent more powerful cancer-fighting antioxidants, a cache of B vitamins, and plenty of chromium, which helps stabilize blood-sugar levels.
Protein is kryptonite to belly fat, and the building block of a lean, toned bod. I have to admit, when Kumai began writing for men’s nutrition-and-wellness publications, she wasn’t too keen on their obsession with protein powders. Yet, as she began to research and experience the wonders of vegetarian protein blends, she soon became a fan. Within weeks of testing the post-workout smoothies for my book, Kumai’s body leaned up; and she had just as much muscle tone as she did when she was running half marathons. Here’s a delicious recipe to try; one sip and you won’t believe it’s healthy since it takes just like a vanilla shake.
Thank you for suggesting consulting your doctor before starting a session of intermittent fasting. My personal trainer (who highly endorses your book & advice) was just talking to me about the subject last week. I’m definitely interested, and think I’d be ok with just two meals a day. I’ll discuss with my doctor later, but may test it out for a couple days this week and see how I feel. Thanks!
Because… Bowel regularity is key for eliminating waste from your body. But unless you're prepping for a medical procedure, skip the colonics and laxative supplements, as they can disrupt the balance of the bacteria in your gut—your microbiota. Healthy bacteria in your colon not only promote regularity but also help you fight infections, manage your weight and even improve emotional health. The watery and looser stools associated with cleanses are not a sign of detoxification; instead, they may indicate dehydration.
The classic weight-loss shake got an additional injection of protein, doubling the old amount while slashing sugar content. The newest version of the long-lived shake comes in creamy vanilla and milk chocolate, so you’ll have to go with lower protein if you want something more creative like cappuccino. The key to the best tasting shake possible: always chill it thoroughly.
Physiologically, calorie restriction has been shown in animals to increase lifespan and improve tolerance to various metabolic stresses in the body.  Although the evidence for caloric restriction in animal studies is strong, there is less convincing evidence in human studies. Proponents of the diet believe that the stress of intermittent fasting causes an immune response that repairs cells and produces positive metabolic changes (reduction in triglycerides, LDL cholesterol, blood pressure, weight, fat mass, blood glucose). [3,5] An understandable concern of this diet is that followers will overeat on non-fasting days to compensate for calories lost during fasting. However, studies have not shown this to be true when compared with other weight loss methods. 
@Mark, Whey protein is fantastic as a meal replacement. When you’re on the cutting phase (dieting) to retain muscle mass, a protein supplement will help with this. Remember though, there is no substitute for food. Consider lean turkey or chicken breast (with the skin off) but half your normal portion with lots of green veggies (which also contains carbs and protein to help keep you fuller for longer!)
There are some downsides, however. As she explains, "By day two you may as well have all your calls forwarded to the toilet because you will be spending a lot of time in the bathroom. The first time I did the cleanse, I was out with my kids at the mall when all of a sudden I needed a bathroom, stat! It was a nightmare, trying to pack everyone up and find the restroom. I learned the mall is not the place you want to be when your body starts trying to eliminate toxins."
