Calories and weight loss -

People should avoid cutting too many calories. Cutting out about daily is a good range to aim for. People should also avoid losing more than 2 lb each week. If a person cuts too many calories and does not get enough necessary nutrients, they can experience some health problems.

The body needs a minimum number of calories to function properly. Cutting too many can increase the risk of health issues, including:. Before cutting calories, a person should talk with their doctor or nutritionist. People with specific health conditions, such as diabetes, may need specialized diets to help them manage their condition.

Some online calculators can help to estimate this. A 1, calorie deficit can lead to weight loss. However, large calorie deficits, or sudden changes in them, can lead to adverse health effects and may even result in long-term weight gain. A calorie deficit of calories may be enough for a person to lose 1 pound over a week.

However, various factors can influence weight loss, including weight, activity level, health conditions, and more. However, aiming for a daily calorie deficit of approximately calories is often a good starting point for weight loss.

Creating a calorie deficit may be helpful if a person wishes or needs to lose weight. A person can do this using a combination of diet and exercise. They should try to focus on eating highly nutritious foods, drinking more water, and exercising regularly. Formulas and online calculators are available to help people estimate how many calories they burn per day.

From there, people can estimate how many calories they should eat to create a calorie deficit. A person should aim to lose no more than 1—2 lbs per week to avoid potential health issues associated with insufficient nutrients. Efforts to lose weight may not work for a range of reasons.

Zigzag calorie cycling is a weight loss approach that aims to counteract the human body's natural adaptive tendencies. Counting and restricting calories, as described above, is a viable method to lose weight, but over a period of time, it is possible for the body to adapt to the lower number of calories consumed.

In cases where this happens, a plateau in weight loss that can be difficult to surmount can result. This is where zigzag calorie cycling can help, by not allowing the body to adapt to the lower calorie environment.

Zigzag calorie cycling involves alternating the number of calories consumed on a given day. A person on a zigzag diet should have a combination of high-calorie and low-calorie days to meet the same overall weekly calorie target.

For example, if your target calorie intake is 14, calories per week, you could consume 2, calories three days a week, and 1, the other four days of the week, or you could consume 2, calories each day.

In both cases, 14, calories would be consumed over the week, but the body wouldn't adapt and compensate for a 2,calorie diet. This also allows a person more flexibility in their diet, allowing them to plan around occasions, such as work or family gatherings, where a person may consume more calories.

Consuming a lower number of calories on other days can allow a person to enjoy these gatherings or even have a "cheat day" where they eat whatever they want without feeling guilty, since they can make up for the excess calories on their low-calorie days.

There is no concrete rule or study that dictates the most effective way to alternate or spread out calorie consumption. How to vary calorie intake is largely up to personal discretion.

Depending on a person's activity, it is generally recommended that the high-calorie and low-calorie days vary by approximately calories, where the high-calorie day is often the number of calories a person needs to consume to maintain their current weight.

For a person with a higher activity level, the calorie difference should be larger. The calculator presents two zigzag diet schedules. The first schedule has two higher calorie days and five lower calorie days. The second schedule increases and reduces calories gradually.

In either case, the total weekly calorie consumption is the same. In the end, regardless of what method you choose to use when approaching weight loss, what's important is picking a strategy that works for you.

Calorie counting and zigzag calorie cycling are only two methods that are fairly interrelated used to achieve weight loss among many, and even within these methods, there are many possible approaches a person can take. Finding an approach that fits within your lifestyle that you think you would be able to adhere to is likely going to provide the most sustainable and desirable result.

Many people seek to lose weight, and often the easiest way to do this is to consume fewer calories each day. But how many calories does the body actually need in order to be healthy? This largely depends on the amount of physical activity a person performs each day, and regardless of this, is different for all people — there are many different factors involved, not all of which are well-understood or known.

Some factors that influence the number of calories a person needs to remain healthy include age, weight, height, sex, levels of physical activity, and overall general health. For example, a physically active year-old male that is 6 feet in height requires considerably higher calorie intake than a 5-foot-tall, sedentary year-old woman.

Though it differs depending on age and activity level, adult males generally require 2, calories per day to maintain weight while adult females need around 1,, according to the U.

S Department of Health. The body does not require many calories to simply survive. However, consuming too few calories results in the body functioning poorly, since it will only use calories for functions essential to survival, and ignore those necessary for general health and well-being.

Harvard Health Publications suggests women get at least 1, calories and men get at least 1, calories a day unless supervised by doctors. As such, it is highly recommended that a person attempting to lose weight monitors their body's caloric necessities and adjusts them as necessary to maintain its nutritional needs.

The main sources of calories in a typical person's diet are carbohydrates, proteins, and fat, with alcohol also being a significant portion of calorie intake for many people though ideally this should be limited since alcohol contains many empty calories.

Some studies have shown that the calories displayed on nutrition labels and the calories actually consumed and retained can vary significantly.

This hints at the complex nature of calories and nutrition and is why many conflicting points of view on the "best" methodology for losing weight exist. For example, how a person chews their food has been shown to affect weight loss to some degree; generally speaking, chewing food more increases the number of calories that the body burns during digestion.

People that chew more also tend to eat less, since the longer period of time necessary to chew their food allows more time to reach a state of satiety, which results in eating less. However, the effects of how food is chewed and digestion of different foods are not completely understood and it is possible that other factors exist, and thus this information should be taken with a grain of salt in moderation if weight loss is the goal.

Generally, foods that take more effort to chew — fruit, vegetables, lean meats, whole grains, etc. It also results in the feeling of satiety for longer periods of time.

Furthermore, certain foods like coffee, tea, chilies, cinnamon, and ginger have been found to increase the rate of calories burned, due to the ingredients they contain.

Healthy lifestyles include being physically active, limiting calories, and ensuring adequate nutrition. Getting enough sleep can help you manage your body weight.

Age, genetics, diseases, medications and environments may also contribute to overweight and obesity. As people age, their body composition gradually shifts — the proportion of muscle decreases and the proportion of fat increases. This shift slows their metabolism, making it easier to gain weight.

In addition, some people become less physically active as they get older, increasing the risk of weight gain. Genetics can directly cause obesity in specific disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome.

However genes do not always predict future health. In some cases, multiple genes may increase susceptibility for obesity, but obesity does not occur without excess food or too little physical activity. See more information.

Some illnesses may lead to obesity or weight gain. Drugs such as steroids and some antidepressants may also cause weight gain. A doctor is the best source to tell you whether illnesses, or medications are contributing to weight gain or making weight loss hard.

Environmental factors such as a lack of sidewalks may keep people from being physically active. Losing Weight Even a modest weight loss, such as 5 to 10 percent of your total body weight, can produce health benefits. Physical Activity for a Healthy Weight Physical activity can increase the number of calories your body uses for energy.

Burning calories through physical activity, combined with reducing the number of calories you eat, can help with weight loss. Physical Activity Basics Physical activity can make you feel better, function better, and sleep better. Learn about the benefits and how to measure progress.
