Quick-fix diets that promise drastic results in a short time period may be enticing, but they are unsustainable.

According to Andy Bellatti, a registered dietitian and nutritionist, a healthy diet and lifestyle is achieved by pairing good food decisions with physiological support, eventually achieving a happy mind and body.

But what’s the best way to start?

Bellatti spoke to Business Insider about all the things you should – and should never do – to get on track within a week.

DO: Drink lots of water.

Water is essential – it regulates the shape of every cell inside our bodies. If we don’t get enough, in fact, these cells begin to shrivel up. The Centres for Disease Control and Prevention recommends choosing water instead of sugar-sweetened beverages to “help with weight management.”

Swapping in a cold glass of water for a single 20-ounce soda will save you about 240 calories.

Bellatti told Business Insider to hydrate, “ideally with water.”


DON’T: Go on a juice cleanse.

If you’re considering a “detox” or “juice cleanse,” you might want to reconsider. Only drinking water, juice, or any other liquefied concoction for more than a few days can set you up for unhealthy eating behaviours or lead to spikes and drops in blood sugar levels, which can spawn cravings and mood swings.

“This is a recipe for ‘hangriness,'” Bellatti said, “that also inaccurately paints all solid food as problematic.”


DO: Cut back on your sodium intake.

Most of us – 9 out of 10 of US adults, according to the American Heart Association – eat too much sodium, and that’s not including any salt added at the table. Too much salt in your diet can cause puffiness and bloating, so cutting back can help you avoid that.

“Sodium retains water,” Bellatti said, “so lowering sodium intake also reduces puffiness.”


DON’T: Start banning foods.

There’s a difference between cutting back on things you eat in excess and banning entire food groups.

Diets that rely on avoiding ingredients (like sugar or gluten) can lead to replacing those things with other ingredients that play the same role in the body (like honey or corn-based foods). Doing this can be dangerous if the replacement products are nutrient-deficient.


DO: Fill up with fibre.

The writer Michael Pollan said it best: “Eat food. Not too much. Mostly plants.”

Fresh, high-fibre vegetables like broccoli, bell peppers, and Brussels sprouts – which the CDC calls “powerhouse foods” – are great sources of key vitamins and nutrients, including fibre, which helps keep you feeling full and satisfied until your next meal.

“Whole, plant-based foods (fruits, vegetables, whole grains, beans, nuts, and seeds) are best,” Bellatti said. “One quick way to add extra fibre to your day: sprinkle chia, hemp, or ground flax over whatever you’re eating for a boost.”


DON’T: Rely on powders and pills.

The problem with diet powders and pills, Bellatti said, is that they often take something that was once a whole food, like a fruit or a vegetable, and process it to separate out one ingredient.

That’s all right for things like cocoa powder, which does have nutrients, but it shouldn’t make up the bulk of your dietary intake.

“When something is a powder, you’re probably using what, a teaspoon or tablespoon at most?” Bellatti said. “And you have to wonder how much that can really do. Versus a cup of broccoli or a quarter cup of cashews. That’s something significant.”


DO: Be mindful of portion sizes.

The baseline portion sizes of our snacks and meals have ballooned over the past 40 years – even the plates and cups we serve them on have gotten noticeably bigger.

The portion sizes of many of our foods – whether fast food, sit-down meals, or even items from the grocery store – on average have grown by as much as 138% since the 1970s, according to data from the Journal of Nutrition, and the Journal of the American Medical Association.

So be mindful of portion sizes, and if you’re eating out, consider taking some of your meal home for later.


DON’T: Focus exclusively on calories.

Focusing too much on calories can be dangerous, too, since the measurement falsely makes it seem as if a calorie of one food is the same as that of another.

“This is especially true when eating at restaurants,” Bellatti said. “Many low-calorie items are loaded with sodium, which retains water and can leave you feeling bloated.”

Plus, keep in mind that for sustained weight loss, you’re supposed to lose only about 1 to 3 pounds a week.

“That tends to be a lot more sustainable than losing a whole bunch at once,” Philip Stanforth, a professor of exercise science at the University of Texas, told Business Insider.


DO: Think positively about the lifestyle change.

Thinking positively about eating and feeling better can help motivate some people to stick to a new lifestyle.

“In terms of changing the way you eat (it’s much more than a ‘diet’), focus on the opportunities and what you can eat as opposed to what foods you’re trying to cut down on,” Dr. Donald Hensrud, who chairs the Mayo Clinic’s division of preventive, occupational, and aerospace medicine, wrote in a blog post for Mayo Clinic. “There are many wonderful foods and recipes to explore, and believe it or not, we can learn to like new foods.”


DON’T: Expect miracles.

ShutterstockPatience is key.

Let’s be real: Eating right for a week won’t counteract decades of subsisting on fries and Frappuccinos. But it is enough to reduce some of the more irritating aspects of those symptoms, like the bloating linked with a high-salt diet or the fatigue associated with blood-sugar crashes.

“The most that can happen in a week’s time is that you make choices that help reduce bloating and puffiness,” Bellatti said. “Any promises beyond that are more about marketing and hyperbole than anything else.”

But committing to treating your body well – even if only for a few days – might be enough to lay the foundation for months or years of future healthy eating. If you can prove to yourself that you can treat your body right (and that it feels good to do so), you just might be more likely to keep it up later on.
