Weight Loss Do’s and Don’ts

Chart of US population with BMI>30

If you have watched the news or read an article recently related to health, you probably know that more than one-third of the U.S. population is considered obese. Obesity is defined as having a BMI equal to or greater than 30 and is based on your weight relative to your height. About another third of the population are considered overweight and are at risk of obesity. Overweight is defined as having a BMI between 25 and 29. These numbers are concerning due to the increased risk of health problems associated with obesity. The causes of this increase in obesity over the past few decades is multifactorial and no one treatment will solve the problem. My concern is that with any problem there are many people willing to offer a solution for the right price. Due to the high number of people living with obesity, the opportunity to sell weight loss products and services for profit is growing and so are the unscrupulous opportunists eager to make money. While there are some good programs and products offered, I want to focus on some important things to consider when trying to lose weight. Here are my weight loss do’s and don’ts.

 

  1. Not all weight loss is healthy.

    1. Don’t skip meals, starve yourself, exercise obsessively or restrict entire food groups.
    2. Do eat regular balanced meals throughout the day, limit your portion sizes, avoid sugary beverages, avoid junk food and be more active.
  2. Anything that promises a 30 lb. weight loss in 30 days is not realistic.

    1. Don’t set your expectations so high that you set yourself up for failure.
    2. Do plan on seeing a 1-2 lb. weight loss per week with the expectation of losing 4-8 lbs. a month. This translates to 48-96 lbs. in a year. Gradual weight loss is better.
  3.  Weight loss does not have to cost a lot of money or severely restrict calories.

    1. Don’t waste your money on expensive diet programs or pre-packaged food. While pre-portioned meals can be helpful, it may not be the most cost effective solution. Calories do matter but restricting calories too much may backfire and lower your metabolism making it harder to keep the weight off.
    2. Do look for more affordable whole foods to incorporate into your diet and plan your meals ahead of time. Most women will need 1400-1600 calories per day and most men will need 1600-2200 calories per day depending on activity level, age, weight and amount of weight loss needed. A registered dietitian can tell you for certain.
  4.  Exercise is an important part of any weight loss program.

    1. Don’t start an intense exercise program if you have not been exercising before. A gradual increase in activity will help avoid injury while building endurance and strength.
    2. Do begin slow and build up over time. Incorporate cardiovascular exercise such as walking, biking or swimming with strength training such as weight lifting to get the best results. Try to get 30 minutes 5-6 days per week.
  5. Weight loss should be just like your medical treatment – individualized for you.

    1. Don’t compare yourself to others. What may work for one person may not work for another. Also your ideal bodyweight may be very different from someone else.
    2. Do focus on your particular goals and what diet and exercise works best for you.
  6. No pill or injection can take the place of a healthy diet and active lifestyle for weight loss.

    1. Don’t think that a pill or injection will solve all your problems without your effort.
    2. Do work on issues that led to the weight gain and use medications if needed as extra assistance to reach your goals. Talk to your doctor if you have made consistent lifestyle changes but still cannot lose weight.

As a dietitian I have heard some crazy ideas about how to lose weight. From very restrictive diets that limit calories to the point of starvation or eliminate entire food groups to avoid certain macronutrients (like carbohydrates) to eating only certain foods in combination with other foods and only at certain times of the day. It can be quite amusing at times. But obesity is serious and there is nothing funny about someone being taken advantage of because they are trying to lose weight. And yes, you can lose weight on just about any of these programs but it is not always a healthy weight loss and may contribute to problems later on. For example, some diets advocate a very low fat diet. While this may save calories, it can also set you up for gall bladder issues. Once you reintroduce foods containing some fat (which you need by the way) you may find yourself having gallbladder issues. This is not a good trade off for a little bit of weight loss.

So my professional advice is to start by restricting the portions of foods that you are currently eating. Eating smaller amounts more frequently can help you avoid being too hungry. Then begin to incorporate healthier fruits and vegetables into your meal plan. Next, start eliminating foods or beverages that you know are unhealthy like sweets and soda. Experiment with different foods in order to get variety in your diet. Choosing fruits and vegetables of different colors makes this easy to do. Be careful when eating out and try cooking without adding excess oil, butter, sugar or salt. Add daily exercise to your routine to burn calories. Make sure you are getting adequate sleep at night. Being sleep deprived can make it harder to handle stress and you may be tempted to eat during the day in order to stay awake. A good 7-8 hours of sleep is ideal.

If these tips do not work for you, see a healthcare professional that can help you identify other possible causes for the unwanted weight such as thyroid issues, hormone imbalances or medication side effects. Diet becomes even more important if any of these are an issue. To find a qualified dietitian in your area that may be able to help, click here.  Feel free to share your comments below.

 

Blood Pressure and Salt: What is the Connection?

Digital blood pressure cuffWhen blood pressure begins to rise, the advice always seems to start with reduce salt intake. While this can be good advice, it fails to consider the complexity and possible other causes of elevated blood pressure. Risk factors for high blood pressure, also known as hypertension, includes:

  • Sedentary lifestyle
  • Excessive sodium intake from processed and fatty foods
  • Low potassium intake
  • Being overweight or obese
  • Excessive alcohol intake
  • Smoking
  • Age greater than 60
  • Race – African American adults are at greater risk than Hispanic or Caucasian adults.
  • Certain diseases or medications

If high blood pressure is caused by another disease or condition, it is termed secondary hypertension. If there is no identifiable cause found, it is termed primary hypertension. Primary hypertension is the most common form and can be related to the risk factors above.

To understand the risk for hypertension, we must understand the physiology of blood vessels. The pressure inside the blood vessel is regulated by hormones that control the blood volume and pressure. When the blood volume increases so does the pressure. Coronary artery disease can also increase pressure inside the blood vessel due to constriction. When the diameter of the vessel wall narrows due to hardening of the arteries (loss of elasticity) or plaque build-up, it increases the pressure. Over time this can lead to more damage of the arteries and gradual increase in blood pressure. High blood pressure is a major risk factor for stroke and heart disease. Unfortunately, there are approximately 75 million people in the U.S. living with high blood pressure.

So, how do we treat high blood pressure? Lifestyle factors should be the first consideration unless blood pressure is dangerously high. If this is the case, medications and/or hospitalization may be required. But for slightly elevated blood pressure, making a few lifestyle changes can go a long way. Weight loss will help if you are overweight or obese. Exercise can also improve blood pressure over time. But be cautious about exercising if blood pressure is very elevated as exercise will make it go up. Avoid tobacco and excessive alcohol intake since these will make hypertension worse. Stress reduction can also help. Dietary changes include reducing intake of processed foods that are high in sodium and fat and eating more fruits and vegetables rich in potassium. Potassium seems to be protective against the effects of excess sodium. Diets such as the Mediterranean or DASH diet are known to reduce blood pressure and heart disease risk.  Some studies also found that getting adequate magnesium and calcium can improve blood pressure. Supplements may be beneficial but nutrients from food is always best.

The question remains however, how much sodium is too much? Americans consume 3,400 mg of sodium per day on average. Current guidelines recommend no more than 2,300 mg of sodium per day. The American Heart Association has lowered the guideline to no more than 1,500 mg of sodium per day for those at risk of heart disease. Some researchers argue that recent studies show limiting sodium too much may do more harm than good. According to them, a very low sodium diet increased the risk for heart disease. Several studies confirm reducing sodium intake improves cardiac risk factors, however the question remains how much should sodium be reduced? We know sodium is necessary for the body to work properly. We do not know for certain how much sodium is needed. Until we can determine this for certain, my advice is “sodium in moderation”. And remember, there is no “one-size-fits-all” when it comes to nutrition. You are an individual so listen to your body and stay healthy!

FOOD LABEL GETS A FACE LIFT

New Food Label

    Revised Nutrition Label

Due to federal nutrition label reform, the Nutrition Facts Label will get an update.  This will revise the old regulations as set forth in the Nutrition Labeling and Education Act of 1990 (NLEA). This act gave authority to the Food and Drug Administration (FDA) for nutrition labeling. Prior to this, food labeling was mostly voluntary and required only if a nutrient was added to a food or it promoted some health claim. But when Americans began consuming more packaged foods, it became clear that guidelines needed to be established in order to provide more information on the nutritional value of those foods. After almost 20 years, it is time to make some changes. There are a few reasons cited for this including an increase in research regarding the link between diet and risk of chronic disease, changes in serving sizes consumed and an emphasis on the overall diet with a focus on calories and serving sizes as important factors. The decision on what to include or eliminate from the food label was derived from scientific evidence, consensus reports, public comments (300,000 comments were received), petitions from consumers, food manufacturers, advocacy groups and the National Health and Nutrition Examination Survey (NHANES). The key changes included mandatory addition of Added Sugars with percent daily value (%DV), new format to highlight calories and serving size, updated daily values and added nutrients of public health significance. Serving sizes will get an update based on typical portions consumed. The addition of Added Sugars under Total Carbohydrates was based on evidence that high intake of added sugars decrease intake of nutrient dense foods and increases calorie intake. We also know that a dietary pattern lower in sugar-sweetened foods and beverages are associated with a reduced risk of cardiovascular disease and it is hard to meet the nutrient needs while staying within calorie limits if getting more than 10% of the total daily calories from added sugar. Added sugars are defined as any sugar that is added during processing or packaging. This includes any syrups, brown sugar, high fructose corn syrup, maltose, honey, molasses, sucrose or lactose that is added. Calories and serving size will be in larger print and displayed more prominently. Daily values will be based on recommended levels of nutrients for a general healthy population and a percentage of this value will be included for total fat, total carbohydrate, dietary fiber, sodium, potassium, calcium and vitamin D. The inclusion of vitamin D and potassium are now mandatory based on the fact that most Americans are not getting enough of these vital nutrients. Calcium and iron will continue to be included but vitamins A and C are no longer mandatory but may be included voluntarily. Each will list the amount as well as percent of daily value (%DV). Trans fat and dietary fiber will stay on label. There will also be a new requirement for food manufacturers to maintain records to verify certain nutrients included.

Serving sizes are calculated based on the reference amounts customarily consumed (RACCs). Since serving sizes have changed over the past 20 years, these will be updated to reflect the change. Approximately 30 out of the 158 reference amounts will change. For example, ice cream no longer is calculated for 1/2 cup but for 2/3 cup, carbonated beverages went from 8 ounces to 12 ounces and yogurt decreased from 8 ounces to 6 ounces. For items that are considered single servings, the food label must indicate calories and nutrients for the entire package rather than per serving size since people typically consume the entire package at one time.

So when are these changes to take effect? Food manufacturers will have two years to comply but there is an exception for those businesses with less than $10 million in revenue who will have 3 years to comply. You will start seeing the new labels over the next year with most in compliance by July 2018.

The intent is for Americans to use this information in order to make informed decisions regarding their food choices. As more people become aware of diet’s effect on health and more information is available, maybe we will see a reduction in chronic disease. This reduction will likely result largely from a reduction in the obesity rate. We know that obesity is a major contributor to chronic disease. According to The Trust for America’s Health, there are 41 states that now have obesity rates over 25%. Twenty years ago no state had an obesity rate over 15%. If the trend continues, 51% of the population will be obese by 2030. Americans consume a total of 31% more calories than they did 40 years ago. Couple that with a mostly sedentary lifestyle and it is easy to see why America’s waistline has grown and so has the rate of chronic disease. They say knowledge is power. May more knowledge also bring us better health!

A Healthy Heart is a Happy Heart

      Heart Health

February is American Heart Month so I thought it would be appropriate to discuss how to keep our hearts healthy. Some tips will not surprise anyone such as don’t smoke, maintain a healthy weight and exercise. But I want to get more specific with what can either prevent or contribute to heart problems. Let’s begin by looking at the top risk factors for heart disease. According to the National Heart, Lung and Blood Institute  (NHLBI) (a division of the National Institutes for Health (NIH)), these include high blood pressure, high cholesterol, diabetes or pre-diabetes, smoking, being overweight or obese, sedentary lifestyle, family history of heart disease, unhealthy diet, having preeclampsia during pregnancy and age (greater than 55 for women). Some risk factors we cannot control such as our age, family history or developing preeclampsia during pregnancy. The good news is we can control the other risk factors in most cases by making some diet and lifestyle changes.  The first thing we need to know is whether we have any risk factors. Do you have a family history of heart disease? Is your blood pressure normal? What are your blood cholesterol levels? Do you have pre-diabetes or diabetes? Do you smoke? Are you considered overweight or obese? Do you get at least 30 minutes of exercise (in addition to your normal daily activity) most days of the week? Do you get 5 servings of fruits and vegetables most days of the week? Do you limit your sodium and saturated and trans fat intake? How about your stress level? Do you have a healthy outlet for managing stress? How you answer these questions determines what areas need focus for making changes. We are going to look at each modifiable risk factor in a series of posts during the month of February. Look for more information on your risk factor(s).

For more information, you can find a free 127-page book “The Healthy Heart Handbook for Women” from the NHLBI website. There are other resources for men as well but this one is particularly geared to create awareness of heart disease in women. Heart disease is still the #1 killer of both men and women in the United States. Let’s work on making our heart happy and healthy this February.
