Health tips from the No-Fad Diet

December 8th, 2011 / tags:, , , / categories: Uncategorized /

For those trying to lose weight, all the sermonizing can be a turnoff. Who doesn’t already know that vending machine chocolate bars are bad, that whole grain is good? That fad diets don’t work and getting fit doesn’t come quick?

There’s no magic formula for losing pounds and keeping them off, but there are strategies that work. The American Heart Association recently published the second edition of its bestseller No-Fad Diet (Clarkson Potter, $27.99), a no-nonsense bible for anyone looking to lose weight, eat healthier and move more.

It’s a collection of advice culled from a review of current research in nutrition, weight management and behaviour modification. Much of the same advice is available from the Dietitians of Canada and the Canadian Heart and Stroke Foundation, from Health Canada and Quebec’s health ministry: Exercise more and eat a healthy, balanced diet that is low in fat and includes a variety of food from each of the four groups.

No-Fad Diet puts it all together in a way that is simple and straightforward. At its core is the concept of energy balance: To keep from gaining weight, you must balance the calories you eat (calories in) with the calories your body uses up (calories out). To lose weight, change the balance in favour of “calories out.”

That’s it. No outlawed food combinations or powders, herbs, meal-replacement bars or pills. No three-week ab-building regimens. Just some commonsense advice for the road ahead.

Here’s a compilation of useful tips for losing weight from NoFad Diet, the Canadian Heart and Stroke Foundation and Nutrition Quebec, a healthy-eating blog by dietitian Charlotte Geroudet:

Think smart

Be aware of your inner voice. Think about how the running dialogue inside your head encourages or excuses bad behaviour. As in: “I’ll have these french fries now, but just a salad for dinner,” or “It’s too icy/cold/ hot/humid/late/early to go out for a walk.”

Practise saying “thanks, but no thanks” to colleagues who bring in baked goods or dinner-party hosts who offer yet another glass of wine.

Learn to recognize true hunger. Before each bite of food, ask: “Am I so hungry that I would eat this even if it were something I didn’t like very much?”

Be especially vigilant around people you love. Research shows that adults tend to eat more in the company of friends and relatives, especially if they are overweight.

Don’t be hard on yourself. It takes about six weeks to form new habits. Be prepared for pitfalls and setbacks. Hitting a plateau is part of the process-the body’s way of readjusting to a reduced food supply. If you stick with it, you’ll start losing again.

Keep a food diary. Know exactly what you eat and why.

Plan ahead

Good planning, not will power, is the key to successful, sustained weight loss.

Plan meals for the next few days to avoid “unconscious eating.” Shop with a detailed grocery list and don’t linger in the supermarket.

Cook extra. Leftovers are a great way to avoid the fast food perils of the food court at lunchtime.

Eat more soup. A container of homemade vitamin-packed soup in the fridge is also excellent “emergency food” for evenings when you’re ravenous but don’t have time to cook.

Set reasonable weight loss goals. Begin by aiming to lose 10 per cent of your body weight. Losing one to two pounds a week is healthy and sustainable.

Start with small steps. Make gradual, manageable changes. Have a low-calorie lunch twice a week. Cook a healthy dinner once a week. Every second day, replace ice cream with fresh fruit.

Or go full throttle. Some behavioural experts say that starting with a strict regime, as opposed to cutting back just a few calories, helps the new habits become ingrained. Then you can ease back after two weeks.

Choose the right strategy for you

A “switch and swap” approach works for some people. Replace margarine or butter on toast with all-fruit spread or unsweetened apple sauce; or use fat-free milk instead of whole milk.

For others, especially those who eat out or travel a lot, the “75 per cent solution” is better. Continue to eat most of the things you like-just less of them. Before beginning each meal, mentally draw a line on the plate to portion out threequarters of what you normally eat. If you always have a muffin for breakfast, eat three-quarters of it. If you eat four slices of pizza at your kid’s hockey game, cut back to three.

Find more nutritious, lower calorie alternatives

Get the most return from each calorie. Eat more vegetables and fruits, fibre-rich whole grains, fatfree and low-fat dairy products and fish and lean meat, as well as unsaturated fats and oils.

Visualize your plate divided into fourths, with two sections for vegetables and fruits, one for grains and starches, and one for a protein.

Eat slowly. It takes about 20 minutes for your brain to register the signal from your stomach that it is full.

Pre-empt restaurant regret. Eat something low in calories- an apple or a bowl of low-fat yogurt-before leaving for the restaurant if you are very hungry. Or drink a glass or two of water while waiting for your food to take an edge off your hunger. And ask the waiter to take away the bread basket.

Move more

Strap on a pedometer. Recording every step will give you a realistic idea of just how active-or inactive-you really are. Wear the pedometer for one week. Add up the daily totals and divide by seven to find out your average number of daily steps. (A daily range of 2,000 to 4,000 steps is considered inactive; 5,000 to 7,000 steps is considered moderately active; 10,000 or more steps is considered very active.)

ScienceDaily (Nov. 13, 2011) — Drinking two or more sugar-sweetened beverages a day may expand a woman’s waistline and increase her risk of heart disease and diabetes, according to research presented at the American Heart Association’s Scientific Sessions 2011.

In this study, researchers compared middle-aged and older women who drank two or more sugar-sweetened beverages a day, such as carbonated sodas or flavored waters with added sugar, to women who drank one or less daily. Women consuming two or more beverages per day were nearly four times as likely to develop high triglycerides, and were significantly more likely to increase their waist sizes and to develop impaired fasting glucose levels. The same associations were not observed in men.

“Women who drank more than two sugar-sweetened drinks a day had increasing waist sizes, but weren’t necessarily gaining weight,” said Christina Shay, Ph.D., lead author of the study and assistant professor at the University of Oklahoma Health Sciences Center in Oklahoma City. “These women also developed high triglycerides and women with normal blood glucose levels more frequently went from having a low risk to a high risk of developing diabetes over time.”

The Multi-Ethnic Study of Atherosclerosis (MESA) included food frequency surveys in 4,166 African-American, Caucasian, Chinese-Americans and Hispanic adults 45 to 84 years old. At the beginning of the study the participants didn’t have cardiovascular disease.

Researchers assessed risk factors in three follow-up exams spanning five years starting in 2002. Participants were monitored for weight gain, increases in waist circumference, low levels of high density lipoproteins (HDL “good” cholesterol), high levels of low density lipoproteins (LDL “bad” cholesterol), high triglycerides, impaired fasting glucose levels, and type 2 diabetes.

“Most people assume that individuals who consume a lot of sugar-sweetened drinks have an increase in obesity, which in turn, increases their risk for heart disease and diabetes,” said Shay, formerly of Northwestern University’s Department of Preventive Medicine in Chicago, where the study was conducted. “Although this does occur, this study showed that risk factors for heart disease and stroke developed even when the women didn’t gain weight.”

Women may have a greater chance for developing cardiovascular disease risk factors from sugar-sweetened drinks because they require fewer calories than men which makes each calorie count more towards cardiovascular risk in women, Shay said.

Researchers have yet to determine exactly how sugar-sweetened beverages influence cardiovascular risk factors such as high triglycerides in individuals who do not gain weight, Shay said, but further work is planned to try and figure that out.

ScienceDaily (Nov. 13, 2011) — Low levels of vitamin C were associated with higher levels of high sensitivity C-Reactive protein (hsCRP) and shorter intervals without major cardiac issues or death for heart failure patients, in research presented at the American Heart Association’s Scientific Sessions 2011.

Compared to those with high vitamin C intake from food, heart failure patients in the study who had low vitamin C intake were 2.4 times more likely to have higher levels of hsCRP, a marker for inflammation and a risk factor for heart disease.

The study is the first to demonstrate that low vitamin C intake is associated with worse outcomes for heart failure patients.

Study participants with low vitamin C intake and hsCRP over 3 milligrams per liter (mg/L) were also nearly twice as likely to die from cardiovascular disease within one year of follow-up.

“We found that adequate intake of vitamin C was associated with longer survival in patients with heart failure,” said Eun Kyeung Song, Ph.D., R.N., lead author of the study and assistant professor at the Department of Nursing, College of Medicine, in the University of Ulsan in Korea.

The average age among the 212 patients in the study was 61, and about one-third were women. Approximately 45 percent of the participants had moderate to severe heart failure.

Participants completed a four-day food diary verified by a registered dietitian and a software program calculated their vitamin C intake. Bloods tests measured hsCRP.

Researchers divided participants into one group with levels over 3 mg/L of hsCRP and another with lower levels. Patients were followed for one year to determine the length of time to their first visit to the emergency department due to cardiac problems or death.

Researchers found that 82 patients (39 percent) had inadequate vitamin C intake, according to criteria set by the Institute of Medicine. These criteria allowed the researchers to estimate the likelihood that the patient’s diet was habitually deficient in vitamin C based on a four day food diary. After a year follow-up, 61 patients (29 percent) had cardiac events, which included an emergency department visit or hospitalization due to cardiac problems, or cardiac death.

The researchers found that 98 patients (46 percent) had hsCRP over 3 mg/L, according to Song.

Inflammatory pathways in heart failure patients may be why vitamin C deficiency contributed to poor health outcomes, the data suggests.

“Increased levels of high-sensitivity C-reactive protein means a worsening of heart failure,” Song said. “An adequate level of vitamin C is associated with lower levels of high-sensitivity C-reactive protein. This results in a longer cardiac event-free survival in patients.”

The use of diuretics may also play a role because vitamin C is water soluble and diuretics increase the amount of water excreted from the kidneys, said Terry Lennie, Ph.D., R.N., study author and associate dean of Ph.D. studies in the College of Nursing at the University of Kentucky in Lexington, Kentucky.

“Diet is the best source of vitamin C,” Lennie said. “Eating the recommended five servings of fruits and vegetables a day provides an adequate amount.”

More randomized controlled trials and longitudinal prospective studies are needed to determine the impact of other micronutrients on survival or rehospitalization, Song said.
