Things to know about weight loss
Whether your weight-loss goals involve trying to lose 5 pounds or more than 50, the same principles determine how much weight you lose and how fast your weight loss will occur. Remembering the following simple healthy eating diet tips and putting them into practice can lead to weight reduction without the aid of any special diet plans, weight loss programs, fitness books, or medications.
Our body weight is determined by the amount of energy that we take in as food and the amount of energy we expend in the activities of our day. Energy is measured in calories. Metabolism is the sum of all chemical processes within the body that sustain life. Your basal metabolic rate is the number of calories (amount of energy) you need for your body to carry out necessary functions. If your weight remains constant, this is likely a sign that you are taking in the same amount of calories that you burn daily. If you're slowly gaining weight over time, it is likely that your caloric intake is greater than the number of calories you burn through your daily activities.
Every adult is in control of the amount of food he or she consumes each day, so our intake of calories is something we can control. To a major degree, we can also control our output of energy, or the number of calories we burn each day. The number of calories we burn each day is dependent upon the following:
- Our basal metabolic rate (BMR), the number of calories we burn per hour simply by being alive and maintaining body functions
- Our level of physical activity
For some people, due to genetic (inherited) factors or other health conditions, the resting metabolic rate (RMR) can be slightly higher or lower than average. Our weight also plays a role in determining how many calories we burn at rest -- the more calories are required to maintain your body in its present state, the greater your body weight. A 100-pound person requires less energy (food) to maintain body weight than a person who weighs 200 pounds.
Lifestyle and work habits partially determine how many calories we need to eat each day. Someone whose job involves heavy physical labor will naturally burn more calories in a day than someone who sits at a desk most of the day (a sedentary job). For people who do not have jobs that require intense physical activity, exercise or increased physical activity can increase the number of calories burned.
As a rough estimate, an average woman 31-50 years of age who leads a sedentary lifestyle needs about 1,800 calories per day to maintain a normal weight. A man of the same age requires about 2,200 calories. Participating in a moderate level of physical activity (exercising three to five days per week) requires about 200 additional calories per day. More strenuous exercise programs, such as those with cardio focus, can burn even more.
How do you lose weight?
The best approach for weight loss is reducing the number of calories you eat while increasing the number of calories you burn through physical activity. To lose 1 pound, you need an expenditure of approximately 3,500 calories. You can achieve this either by cutting back on your food consumption, by increasing physical activity, or ideally, by doing both.
For example, if you consume 500 extra calories per day for one week without changing your activity level, you will gain 1 pound in weight (7 days multiplied by 500 calories equals 3,500 calories, or the number of calories resulting in a 1-pound weight gain). Likewise, if you eat 500 fewer calories each day for a week or burn 500 calories per day through exercise for one week, you will lose 1 pound.
Examples of the calorie content of some popular foods and beverages include the following:
- One slice of original-style crust pepperoni pizza - 230 calories
- One glass of dry white wine - 160 calories
- One can of cola - 150 calories
- One quarter-pound hamburger with cheese - 500 calories
- One jumbo banana nut muffin - 580 calories
Any fitness activities you do throughout the day are added to your BMR (basal metabolic rate) to determine the total number of calories you burn each day. For example, a 170-pound person who spends 45 minutes walking briskly will burn about 300 calories. The same time spent on housecleaning burns about 200 calories, and mowing the lawn for 45 minutes consumes around 275 calories.
How fast should you expect to lose weight?
Most fitness and nutrition experts agree that the right way to lose weight is to aim for a safe, healthy rate of weight loss of 1 to 1½ pounds per week. Short-term dramatic weight loss is rarely healthy or sustainable over time. Modification of eating habits along with regular exercise is the most effective way to lose weight over the long term. It is also the ideal way to ensure that the weight stays off.
Starvation or extreme diets may result in rapid weight loss, but such quick weight loss can be unsafe and is almost impossible to maintain for most people. When food intake is severely restricted (below approximately 1,200 calories per day), the body begins to adapt to this state of poor nutrition by reducing its metabolic rate, potentially making it even more difficult to lose weight. This also happens when dieters engage in fasting or skipping meals. It is also possible to experience hunger pangs, bouts of hypoglycemia, headaches, and mood changes from overly stringent dieting. These health symptoms can result in binge eating and weight gain. Since a highly restrictive diet is almost impossible to maintain for a long time, people who attempt to starve themselves thin often start to gain weight again when they stop dieting and resume their former eating habits.

The no-diet approach to weight control
By adopting sensible eating habits and practicing portion control, you can eat nutritious foods so that you take in as many calories as you need to maintain your health and well-being at your ideal weight. Often, weight loss occurs on its own simply when you start making better food choices, such as avoiding
- processed foods,
- sugar-laden foods,
- white bread and pasta (substitute whole-grain varieties instead),
- foods with a high percentage of calories from fat, such as many fast foods,
While nothing is absolutely forbidden, when you do succumb to temptation, keep the portion size small and add a bit more exercise to your daily workout.
By replacing some unwise food choices with healthy ones, you'll be cutting back on calories. If you add some moderate physical activity, you have the perfect plan for losing weight without the need for special or inconvenient (and often expensive) diet plans. It's also important to follow healthy eating guidelines in general, even after you have lost weight. This should include sufficient amounts of protein, vitamins, and minerals with limited amounts of fat and sugar.
An example of a successful no-diet weight-loss journey
A 45-year-old woman complains that she has gradually put on 12 pounds over the past year. In the last month, she's faced a stressful work deadline and added another 4 pounds to her frame.
This individual's goal is to lose the 16 pounds she has gained. Since her weight has been gradually increasing, she knows that she is consuming more calories than she is burning, especially with her sedentary job. She decides that losing weight at a rate of 1 pound per week (equal to a deficit of about 3,500 calories, or cutting 500 calories per day) would be acceptable and would allow her to reach her goal in about four months.
She decides to make some changes that will allow her to cut back an average of 250 calories per day.
- Skipping a large glass of sweetened iced tea will save about 200 calories.
- Substituting mineral water for the cola she regularly drinks during meetings can save another 150 calories.
- Foregoing her morning muffin snack (or eating only half a muffin) can also save 250 calories or more.
To reach her goal of a 500-calorie-per-day savings, she adds some exercise.
- Getting up early for a 20-minute walk before work and adding a 10-minute walk during her lunch break add up to a half hour of walking per day, which can burn about 200 calories.
- On weekends, she plans to walk for 60 minutes one day and spend 1 hour gardening the next day for even greater calorie burning. If walking for 60 minutes is too much, two 30-minute walks one day would burn the same number of calories.
- Twice per week she plans to stop at the gym on the way home from work, even if only for a half hour of stationary cycling or swimming (each burning up to 250 calories).
By making just some of the dietary cutbacks mentioned and starting some moderate exercise, this individual can easily "save" the 3,500 calories per week needed for a 1-pound weight loss, leading to a healthy rate of weight loss without extreme denial or deprivation. Furthermore, her changes in diet and lifestyle are small and gradual, modifications that she can maintain over time.
What about special diet plans (fad or extreme diets and popular diets) and weight loss programs?
Many people prefer to have a set of rules to follow when dieting. Others may crave emotional support from attending counseling sessions or meetings. Diet products, fitness and nutrition books, and health services have become a billion-dollar industry, so there are obviously many people looking for help with weight control. Before you jump on the latest diet bandwagon, remember that organized diet plans and programs can only result in weight loss if you burn more calories than you consume. No dietary supplements, exercise devices, combinations of foods, or specific patterns of eating will change this fact.
Some examples of popular diet plans and programs include the Atkins diet, The South Beach Diet, Weight Watchers, Jenny Craig, cutting carbs, no-carb diets, Body for Life, ketogenic diet, high-protein diets, Dr. Andrew Weil's diet plan, and the Ornish diet. All of these diets have their proponents, and all of them have been successful for some people. Because one's appetite, eating habits, and preferences vary widely among individuals, before you decide on a diet plan, ask yourself if the plan sounds realistic to you. If the plan involves rigorous measuring of portions and calorie counting, are you up to the task? If you're forbidden to eat certain foods, will you develop cravings for them? Do you feel that you will feel comfortable adhering to the diet guidelines? Will the diet's requirements fit easily into your daily schedule? Finally, consider that once you've lost weight, you may regain the weight if you return to your previous eating habits, so any weight-loss plan should be something you can live with for a long time. Your health care provider can recommend a consultation with a dietitian or nutritionist if you would like help evaluating or developing a weight loss or healthy eating plan.
Remember that the most successful weight management comes from dietary changes and healthy eating choices that will stay with you over time, not from diets that leave you feeling deprived or result in binge-eating episodes.
When should weight-loss medications or surgery be used?
Although medical treatment (for example orlistat [Alli, Xenical]) is available, they should only be used by people who have health risks related to being obese. Doctors usually consider medications to be an appropriate treatment in patients with a BMI greater than 30 or in those with a BMI of greater than 27 who have other medical conditions (such as high blood pressure, diabetes, high blood cholesterol) that put them at risk for developing heart disease. It is not recommended that medications be used for cosmetic weight loss or to lose small amounts of weight.
Weight-loss surgery is also available for people with severe obesity whose attempts to lose weight through other medical treatment methods have failed. Most experts agree that bariatric surgery, or surgery to promote weight loss, should be reserved for the morbidly obese (those who have a BMI greater than 40) or those with a BMI of 35 to 40 with obesity-related health problems like cardiovascular disease, diabetes mellitus, hypertension, or severe sleep apnea.
Why is weight loss important?
Maintenance of healthy body weight has health benefits and is important for maintaining both physical and emotional well-being and disease prevention. Excess weight, body fat, and obesity have been associated with an increased risk for numerous health conditions, including
- heart disease (including heart attack),
- high blood pressure,
- some types of cancers,
- sleep apnea, and
- elevated blood cholesterol levels.
It should be noted that a reduction in weight for those who are overweight can make a major impact on the health conditions listed above. Many overweight people also report improved mood, increased self-esteem and motivation, and feeling healthier in general after they have lost weight.
12 tips for successful weight loss
- The desire to lose weight must come from the individual. If you're truly ambivalent about making changes in your lifestyle or are doing this to please someone else, you're likely to fail. When making changes, decide what's right for your lifestyle. Your best friend's diet and exercise plan may be completely wrong for your health habits and interests. The key is to find a system that works for you.
- Don't blame yourself if you aren't perfect. If you once fail at your attempt to curtail your overeating, it doesn't mean you are a failure at weight control and that you should just give up. Accept that you made a poor choice, but don't let that poor choice influence the rest of your meal plan. The same holds true with exercise. Skipping a few workouts doesn't mean you can't get back on track. Weight control does not involve making perfect choices all the time; rather it's about attempting to make good health choices more often than poor ones.
- Don't go hungry. Make sure not to skip meals, and always have some healthy low-fat snacks on hand. When you starve yourself, you are more likely to overeat and make bad food choices. Try to eat healthy, regular meals.
- Avoid surroundings where you know you're tempted to make poor food choices. Everyone has a time when we're most likely to overeat, whether it's the morning coffee break or after-work gathering with friends. Try to plan other activities or distractions for those times, or plan in advance how you're going to handle them and stick to it.
- Surround yourself with people who support your efforts. Even our good friends can knowingly or unknowingly sabotage weight-loss attempts. Spend time with those people who will not pressure you to make poor food choices.
- Decide on some nonfood rewards for yourself when you reach interim goals. For example, at the end of the first week of healthy eating or after the first 5 pounds are lost, buy yourself a new DVD, app, or book.
- If you have a slip-up, this is no reason to give up. Giving in to temptation and overeating doesn't have to mean the end of your healthy eating plan. After the overeating episode, just resume the healthy eating plan and forgive yourself.
- Stock your pantry and refrigerator with healthy foods. Get rid of the high-calorie, low-nutrition snacks like chips and candy. But don't forget to have plenty of healthier options available as well, such as popcorn (hold the butter, try Parmesan cheese sprinkles), low-fat cheese and yogurt, fruit, instant cocoa without added sugar, sugar-free popsicles or puddings, or whatever appeals to you when you're hungry for a snack.
- Study the Internet or your cookbook collection and identify some low-fat recipes you would like to try.
- Set small goals and focus on these rather than the "big picture." Decide where you want to be in a week or in a month rather than focusing on the total amount of weight you'd like to lose.
- Don't compare your weight loss to others. Everyone is different and has different metabolic rates. People also vary in the number of calories they burn daily or how much exercise they do. Aim for a healthy rate of weight loss, and don't measure yourself by what others are doing or their results.
- Seek out restaurants and venues where you can stay on track. Many restaurants offer nutritional information and calorie content on their menus, and it's often possible to modify your choices. Get the salad dressing on the side or hold the butter. Substitute vegetables for fried foods. Even starting the meal with a green salad can make you eat less of the high-calorie main dish while adding some vitamins and fiber to the meal.

Gastric Bypass SurgeryGastric bypass surgery is a procedure that creates a small stomach pouch to restrict food intake and constructs bypasses of the duodenum and parts of the small intestine to decrease one's ability to absorb nutrients from food. There are two types of gastric bypass operations: Roux-en-Y and extensive gastric bypass. Patients who undergo gastric bypass surgery will need to take nutrition supplements due to limited absorption of certain vitamins and minerals.
Heart Disease: Warning Signs of Cardiovascular Disease
Heart disease (coronary artery disease) occurs when plaque builds up in the coronary arteries, the vessels that supply blood to the heart. Heart disease can lead to heart attack. Risk factors for heart disease include:
- High blood pressure
- High cholesterol
- Family history
Angina, shortness of breath, and sweating are just a few symptoms that may indicate a heart attack. Treatment of heart disease involves control of heart disease risk factors through lifestyle changes, medications, and/or stenting or bypass surgery. Heart disease can be prevented by controlling heart disease risk factors.
High Blood Pressure (Hypertension)
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.
Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.
The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.
If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.

StrokeA stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic). Symptoms of a stroke may include weakness, numbness, double vision or vision loss, confusion, vertigo, difficulty speaking, or understanding speech. A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
