The Whole30 program is only 30 days, but it’s a very restrictive 30 days. You’re urged to eat real, whole foods, including lots of veggies, while carving out things like sugar, grains and dairy. There is no “cheating” – even a chew of sugar-free gum or splash of skim milk in your coffee sends you right back to day one so the body can completely heal from inflammatory foods, diet co-creators Melissa Hartwig and Dallas Hartwig say.A couple things you don’t have to worry about on the Whole30 plan are counting calories and weighing or measuring yourself. In fact, the plan forbids the latter in order to bring participants’ attention to the benefits of healthy eating outside of weight loss. If you usually go out to eat or order take-out, you’ll need to learn to meal prep, grocery shop (with a plan!) and cook. If you’re a social butterfly, you’ll need to strategize how to order water and carrot sticks at the bar instead of beer and wings – or stay home. Fortunately, the program’s resources suggest solutions to these and other conundrums that may pop up. What’s more, the program’s strong emphasis on social – much of it virtual – support can keep participants inspired and accountable.The Whole30 program is outlined neatly online, where followers can read FAQs, lists of foods that are and aren’t off-limits and download a program guide. Melissa Hartwig’s latest book, “Food Freedom Forever: Letting Go of Bad Habits, Guilt, and Anxiety Around Food,” details how to stay in control of food, rather than allowing it to control you, for a lifetime.
"CrossFit is not a specialized fitness program, but a deliberate attempt to optimize physical competence in each of 10 recognized fitness domains," says founder Greg Glassman in the Foundations document. Those domains are cardiovascular and respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy.
That said, plenty of people who try the Whole30 diet do end up losing some weight. "The benefit of Whole30 is that it encourages eating whole foods, which are foods in their most natural state," says nutritionist Sara Haas, RDN, LDN. Cutting out sugar means that you'll probably end up avoiding empty calories from baked goods, and alcohol. You might also find that your belly feels flatter as a result of avoiding highly processed packaged foods, which tend to be loaded with sodium.
Some randomized controlled trials have shown the Paleo diet to produce greater short-term benefits than diets based on national nutrition guidelines, including greater weight loss, reduced waist circumference, decreased blood pressure, increased insulin sensitivity, and improved cholesterol. However these studies were of short duration (6 months or less) with a small number of participants (less than 40). [4-6]
For many years Arthur De Vany Ph.D. has been writing a book called Evolutionary Fitness on "What Evolution Teaches Us About How to Live and Stay Healthy." The diet he follows fits into my core diet definition. He may have been the first one to use the paleo diet to maximize fitness. His current site is Art's Blog on Fitness, Health, Aging, Nutrition and Exercise [archive.org].
So it's no surprise people are looking to the Paleo-inspired diet to help them lose weight. But before you jump on the 30-day train ride for the sole purpose of shedding pounds, know this: At its core, Whole30 is an elimination diet inspired to help you feel your best—it's not a weight loss plan. There's no calorie counting and absolutely no tracking of macros, carbs—you name it. People are advised to step on the scale only at the start and end of the program.
Instead, introduce one new food every three days, since food sensitivities can take up to three days to show symptoms, and write down how you're feeling each day. "Keep portions small and enjoy new foods along with the old foods that were allowed," says Shapiro. "Remind yourself to start slow – you can now eat these foods regularly so there is no need to overindulge."
CrossFit is promoted as both a physical exercise philosophy and a competitive fitness sport, incorporating elements from high-intensity interval training, Olympic weightlifting, plyometrics, powerlifting, gymnastics, girevoy sport, calisthenics, strongman, and other exercises. It is practiced by members of over 13,000 affiliated gyms, roughly half of which are located in the United States, and by individuals who complete daily workouts (otherwise known as "WODs" or "workouts of the day"). CrossFit has been criticized for allegedly causing people to suffer from unnecessary injuries and exertional rhabdomyolysis.
