Most people need around 1.5-2.5 litres of water per day, depending on your size and how active you are – more if you are very active or working out in heat. Of course 4-5 litres of water per day is not healthy, especially if you are also eating enough food! Cassey’s recommendations on this calendar are not unhealthy if you already drink a healthy amount of water – at most she’s recommending to drink 5 cups more than you would normally (1 US cup is – I think – about 250 ml or a quarter of a litre). I normally drink 2 litres of water a day, so following this calendar I would be drinking at most just over 3 litres. That’s not unhealthy.
Beware the Kindle edition unless you can read teensy print. The tables cannot be enlarged enough for me to see. Yes, I can pull them up on my PC but that defeats the purpose of buying it on the Kindle. As for the diet, it is very similar to what I am doing anyway but something changed last year and I gained 15 pounds - all of it on my belly - and cannot get it off. I'm going to see Dr. Randolf this coming week and give his hormone balancing a try. My primary care provider had me on compounded natural Estriol and progesterone for 15 years. At first, the amount was so high that my breasts grew from a C+ to DD in four years (I don't recommend that as a way to enlarge your breasts because I also got suspicious looking cysts that required a biopsy, stretch marks and they are heavy and droopy. My doc prescribed estrogen and progesterone because I had severe insomnia and some hot flashes. I still have insomnia and hot flashes even with the now-lowered dose. So, time to try something different. Will update in a few weeks. BTW I went off both estrogen and progesterone for a few months when I was traveling and the curl came back to my hair. My hair went straight when I went on the pill in 1968. I did not have any estrogen when I was 11 and I was healthy. Maybe I don't need it now.
UPDATE (1/16/17)...I initially gave this a 4/5 thinking it was sound, smart advice, but 13 months later, after reading a number of nutrition books, I've come to understand a lot of the bad advice given in this book. While there are some good points on antibiotics, the advice and justification of Whole Grains are terrible (frankly, I dismiss anyone's nutritional advice when they say you need to eat whole grains; whole grains suck; see Wheat Belly or Undoctored by William Davis and/or Eat the Yolk ...more
A note on vegan/vegetarian diets: This is another topic that entire books and articles are written about, so we won’t dive into them here. Of course, it is absolutely possible to build muscle or lose fat on a vegan/vegetarian diet. Certainly you can get to a flat stomach, you just need to be diligent with your calorie tracking and macros, like we recommend you do above.

Protein drinks are great ways to get a monster dose of belly-busting nutrition into a delicious, simple snack. But most commercial drinks are filled with unpronounceable chemicals that can upset our gut health and cause inflammation and bloat. And the high doses of whey used to boost protein levels can amplify the belly-bloating effect. The Zero Belly solution: Try vegan protein, which will give you the same fat-burning, hunger-squelching, muscle-building benefits, without the bloat. (Here's a complete guide to easy-to-digest plant proteins.)

It's not just about weight loss. Having great gut health is linked to good health throughout your body. Scientists in this rapidly growing field are finding connections between gut microbes and the immune system, weight loss, gastrointestinal health, , allergies, asthma, and even cancer. With every study that's published, scientists become more convinced that having a healthy gut leads to having a healthy body.


Take off your “fat jacket.” It’s a simple analogy, but helps make the point about the types of exercise that offer the best results for fat reduction and, in turn, a flatter stomach. Think of your body’s layer of fat covering your stomach (and elsewhere) as a “jacket” (one of its purposes, after all, is to hold in body heat). Your exercise goal is to shed that jacket.[7]
Target your deepest ab muscles with The Boat: Lie face up on a mat with arms by your sides. Lift your upper body off the ground by rolling through the spine and reaching arms forward. At the same time, raise your legs so that you're balancing on your butt, knees bent and shins parallel to the ground. Slowly roll back down onto the mat, lowering legs and arms. That’s 1 rep. Do 5 reps per set, resting 30 to 60 seconds between sets.

Seated medicine ball twists are a great way to get a toned midsection because they target your obliques while also engaging your abdominals and lower back muscles. When doing this exercise, Mark advises people to keep their feet on the ground. “This one is all about form, so keep your feet on the ground, lean back just enough to feel an engagement in your abdominals, and make a nice full turn with your shoulders,” he explains, noting you should feel that satisfying core burn in no time.
Lie on the floor, face down, and support your upper body on your elbows, forearms, and hands. Slowly lift the rest of your body off the floor until you're on your toes. Keeping your body straight, hold for as long as is comfortable, then slowly lower and relax. Repeat as many times as possible until fatigued. For an added challenge, raise one leg at a time, as shown.
Oh my, two days isn’t long enough to even begin to start seeing results! After the complete challenge you’ll start seeing something change. Your body hasn’t even had a chance to start losing it yet. Also, don’t just rely on this challenge and include other exercise into your daily routine also. Cardio workouts on Cassey’s youtube channel are fantastic as well as many other body sculpting videos. Also control your food intake and track everything you eat and drink! My personal trainer told me it takes up to 6 weeks to fully see results as we all know nothing will make fat drop off over night, or two nights in this instance. Patience and perseverance is key i’m afraid. Stick at the challenge and look in the mirror when it’s finished!
Make dessert an occasional treat rather than an everyday event so it doesn’t become a habit, says Rumsey. If you’re already feeling bloated, eating sweets full of simple carbs could just make it worse, says Armul. “But if it’s been a healthy day and you’ve stayed active, a small portion of dessert should be fine and won’t cause major bloating,” she says. The key to making it fit into your flat-belly day is sticking with one small portion—a serving of ice cream is probably smaller than your usual scoop (or two)—or picking a healthier choice, like frozen fruit, to satisfy your sweet tooth.

Sylvia's age, weight gain, and mild depression were common indicators of an underlying hormonal imbalance, specifically estrogen dominance. I told Sylvia that I could help her without diet pills or antidepressants. After following the plan for six weeks, she walked into the office a changed woman. She had lost nine pounds and an inch and a half from her waist. Within ten weeks, she celebrated with a shopping spree for new size 8 pants. In my practice, I have helped thousands of people like Sylvia, people who had no idea that shifting hormone production was the hidden culprit causing their weight gain.
Like lunch, your evening flat-belly meal should consist of half non-starchy vegetables, one-quarter whole grains, and one-quarter protein. That combination is packed with nutrients, but will also keep you full. A healthy plate might contain vegetables roasted in olive oil, a serving of quinoa, and three to six ounces of chicken or fish, says Rumsey. (Read these secrets nutritionists won’t tell you for free.)
Get more "bang" for your ab-exercise "buck." Ideally, instead of focusing on muscle-toning exercises that target only your abdominals, you should seek out alternatives that utilize other muscle groups as well. They often require more exertion, which can help with fat burning. Also, additional muscle tone in the back, chest, shoulders, legs, etc. can improve posture and otherwise help make your belly appear slimmer.
The last protein you’ll be cooking this week is another lean meat, pork tenderloin. Congratulations! You made it through the week without red meat! The average American eats about 3.3 oz of red meat per day. Eating too much red meat has been linked to chronic, inflammation, heart problems, cancer, and an unhealthy gut, so our flat-belly plan eschews the stuff. That doesn’t mean you shouldn’t have it, though! Experts recommend having only 3 servings of red meat a week—but make sure it’s grass-fed beef, not grain-fed. This source is teeming with heart-healthy omega-3s and fat-burning conjugated linoleic fatty acids. It’s also lower in inflammatory saturated fats.
Americans are getting less sleep than ever these days and it’s taking a toll on our health—most visibly on our waistlines. Losing just 30 minutes of sleep per night can make you gain weight, according to a study done by the Endocrine Society. Worse, that weight is more likely to go straight to your tummy. Instead, the researchers found, the best sleep cycle is one that follows your natural circadian rhythms, which means sleeping and waking around the same time as the sun. Here are the 7 ways to banish belly bloat in your sleep.
Hold a resistance band taut between your hands and lie on the floor face up, with legs extended and arms overhead. Pull abs in, tuck your chin, lift arms toward the ceiling, and roll head, shoulders, and torso up and over your legs as far as you can. Keep heels firmly on the floor and reach your hands towards your feet. Pause, then slowly roll back down. Do 5 to 8 reps with 30 minutes of cardio 5 to 6 times a week.
HOW TO MAKE IT: Preheat oven to 400 degrees F. Lay two 5-oz servings of salmon (skin side down) on a lightly oiled tray alongside a small bunch of asparagus. Season salmon with salt, pepper, and paprika, and the asparagus with salt and pepper. Drizzle over 2 tablespoons of garlic-infused olive oil and the juice from half a lemon. Place in oven and cook until fish flakes easily with a fork, about 16-18 minutes. In the meantime, cook up 3 servings of brown rice — one you’ll use tonight, and two you’ll use later on in the week. Save two-thirds of the asparagus and the second salmon fillet for leftovers.

Another metabolism-boosting tip: Eat every three to four hours, and that should include making time for breakfast. Research shows that people who miss a morning meal experience a surge in a hunger-related hormone later in the day. Regular snacks (which should include fiber-filled complex carbs and protein!) will keep you feeling full and your body burning cals at a steady rate.
Shift your weight into your right foot. Hug your left shin into your chest, then extend it straight back behind you so it’s parallel to the ground. Flex your left foot and point the toes down. Bring your fingertips to the ground to stabilize yourself if you need to. Reach your arms out in front of you so your body is in a straight line from your fingertips all the way down your back and out through your left heel. Stay here for 3 long, deep breaths then slowly return to standing. Repeat on the other side.
I’ve completed the third line. I just realized I’ve been doing the leg lifts wrong. I was doing them as alternating, not as double. No wonder it’s felt so brutal! As I said on the Thigh challenge, I didn’t understand why there was 12 days of doing exercises 1-3 ten times, and 6 days doing exercise 4 ten times. Now that I’ve completed Day 18, it makes perfect sense. My abdominal area is getting stronger, which is helping with my belly fat. Today after doing all five exercises 10 times I thought “I’m supposed to do these 22 times?!” My next thought was “No, I’m supposed to increase these five exercises by a count of 1 over the next 11 days and finish up with 22 times.
Stress skyrockets your levels of cortisol, often called "the belly fat" hormone because it signals to the body to store fat around your waist. Add the daily stressors of living our modern lifestyle and you can see how cortisol can be constantly coursing through your veins. This perma-stress mode isn't good for a lot of healthy reasons, your tummy being just one of them, so it's important to take time every day to de-stress. Yoga, meditation, walking, journaling, doing a hands-on hobby, or playing a musical instrument are all great time-tested methods. (Hint: Know what isn't? Watching television. The boob tube actually increases your levels of cortisol!)
“Soda, both diet and regular, have absolutely no nutritional benefits and may even have serious health implications,” says Gina Consalvo, MA, RD, LDN, a Pennsylvania-based registered dietitian. “Not only are they loaded with empty calories, harmful preservatives, sugar or artificial sweeteners, they also have dangerous artificial coloring derived from coal sources,” explains Consalvo. But that’s not even the worst part. “To prevent mold growth in the cans and bottles, makers add the preservative potassium benzoate (a known carcinogen linked to thyroid damage, leukemia and other cancers) into the cans.” Consalvo suggests eliminating soda and drinking water, seltzer or detox tea instead.
Spanx are maybe no one's idea of a good time, but sometimes you just need a little extra (firm) help to flatten your tummy to wear your favorite dress or for a special evening out. And there's nothing wrong with turning to technology to help you get there. Body shaping undergarments have come a long way in the past few years with more breathable fabrics and styles for both men and women.

As part of the Flat Belly Plan, have an anti-inflammatory snack in the afternoon. Snacks should be rich in flavonoids, which are powerful antioxidants that help curb inflammation. They're the natural compounds that give berries and other fruits their vibrant color. Try a sliced yellow bell pepper with hummus or a bowl of mixed berries drizzled with dark chocolate. Click here for more anti-inflammatory food suggestions.

Honestly, children and young teens shouldn't push themselves too hard, however, if desperate try drinking cold iced water before every meal (helps lose excess fat), eating smaller portions, and doing 10-30 minutes of exercise in the morning. Also, leisure activities like swimming are great for working abs and the rest of your body at the same time.
