Clarity of Mind — Studies suggest that people carrying extra weight are more likely to experience dementia than those maintaining healthy weights. Causes of the phenomenon are not exactly clear; perhaps relating to fat carried in the abdomen or hormonal changes resulting from it.

Significant percentages of added dementia risk come with obesity. Cancer Risk — General good health helps the body beat back harmful influences, including cancer. Studies show that obesity enhances cancer risk, especially among women.

Hormones produced by fat may be responsible for increased breast cancer risk, as well as other forms of cancer impacting women. Estrogen responds to lost weight, reducing the amount produced. There is also reason to believe women suffering from cancer recover faster at optimal weights, than women carrying extra pounds.

The two-fold benefit provides powerful incentives for losing excess fat. Heart Health — There is a strong causal relationship between obesity and heart ailments, confirmed by targeted research in the area. In addition to high cholesterol and diabetes risk, elevated heart-attack occurrences are documented among obese patients.

In fact, overweight Americans are much more likely to experience heart difficulties at younger ages, than those maintaining healthy body mass indexes. Dietary changes, including eating more green vegetables, stimulate weight loss and add important heart-healthy calories.

Formulas incorporated into this online calculator are based on a mathematical model developed by Kevin Dennis Hall, Ph. The model is much more accurate in predicting weight loss because it factors in the body dynamics and physiological changes that occur when the body is in a calorie deficit state.

These factors include changes in the amounts of body fat and lean body mass, glycogen, sodium, extracellular fluid levels, and changes in the thermic effects of feeding.

To illustrate, if you're a year-old, 6-foot sedentary male weighing pounds, your body would burn around 2, calories daily, and you would need to intake that same amount of food energy to maintain your current weight.

Say you then go on a 1, calorie a day diet, a calorie deficit, to try and lose 85 pounds for a healthy BMI. You would be eating 7, fewer calories a week.

If we applied Hall's mathematical model instead, it would show that it takes almost 70 weeks for that same weight loss.

Body weight loss through caloric restriction does not continue downwards indefinitely in a linear fashion as the kcal rule would suggest. Rather, the loss levels off nonlinearly because of body dynamics. Hall's model much more closely approximates the actual weight loss curve. This calculator also calculates your Total Daily Energy Expenditure TDEE and Resting Metabolic Rate RMR at your starting and goal weights.

RMR is the amount of energy your body burns while at rest. RMR is factored into TDEE. The calculator also suggests intake amounts for macronutrients carbs, protein, and fat based on the required caloric intake to reach your goal weight. Macros are set within an acceptable range according to IOM dietary guidelines.

As a general rule, women should not eat less than 1, calories a day and men not less than 1, calories a day. Nutrition therapists will tell you that food group targets and nutrient recommendations will not be met below those levels.

Eating too few calories will make weight loss slower and more difficult by slowing your metabolism. Your body will sense that food is in short supply and will slow down your metabolic rate to try and protect it from starvation. It occurs even if you are overweight and deliberately trying to lose weight - the slower the metabolic rate, the slower the calorie burn.

The equation sounds simple enough, and one may think that just by eating very few calories, one can maintain a calorie deficit and lose weight. But it is not so. For starters, if you eat too few calories, you will always feel hungry and tired.

It will also slow down your metabolism and make losing weight difficult. You may start losing muscle mass , which is not good for your health. Another crucial point is that everyone responds to a diet change differently, depending upon their metabolic health. So it is very difficult to predict individual weight-loss results accurately.

A simple trick is to figure out how many calories you burn every day and follow a calorie deficit of to calories for a healthy weight loss. The number of calories that you burn every day, i.

Our calculator uses the Mifflin St Jeor equation to calculate your basal metabolic rate BMR and then calculates your TDEE by taking into account your physical activity levels.

We then use this information to provide an estimate of the time it would take for you to reach your target weight by following your chosen calorie deficit. Remember as you lose weight, your TDEE changes, and so does your recommended calorie intake.

If you are wondering what my calorie deficit is for a healthy weight loss, fret not! Let us see how you can use our calorie deficit calculator to help you find a solution to your problem. Enter your personal information, like sex, height, current weight, age, and activity level. You can enter your calorie deficit in two ways: by choosing your desired weight loss pace or by typing the calorie deficit value manually.

The calorie deficit calculator will display your body's calorie requirements for maintaining your current weight. It will also show an estimate of your weight change over time for your chosen calorie deficit and some recommendations for a calorie deficit diet.

Note: This calorie deficit calculator does not take into account body dynamics and other complex physiological changes that occur when you are in calorie deficit.

It is vital to pay attention to what we eat or drink every day to create a calorie deficit. This doesn't mean that we should start depriving ourselves of food. We will only end up feeling miserable, hungry, and lethargic.

Therefore, we should try to eat food that is nutrient-rich but low in calories. According to the dietary guidelines for Americans , a healthy diet should include:.

In addition, we can also follow certain recommendations to reduce the calorie content of our meals, for example:. We recommend checking our IIFYM calculator to determine the optimal amount of nutrients you should consume every day.

You can also use our water intake calculator to estimate your daily water intake. To be in a calorie deficit mode, we should burn more calories than we consume. We can achieve this either by reducing the calories we eat and drink, or increasing our physical activity levels.

Ideally, both. For healthy weight loss, i. To lose 1 pound of fat, we need to burn about calories. Therefore, assuming a calorie deficit of cal per day, you should be able to lose pounds in the first week.

Research has shown that it is possible to build muscle on a calorie deficit by following a low-calorie, high-protein diet. A calorie deficit diet is a diet that is low in calories and helps to maintain a calorie deficit. For healthy weight loss, it is always advisable to eat a nutrient-rich, high-protein, and low-calorie diet consisting of fruits, vegetables, healthy oils, lean protein, and whole grains.

Most of us need a minimum of calories per day to stay healthy. We also need the energy to perform our everyday chores and exercise, hence eating less than calories will be harmful to our health and also make us feel tired all the time.

To calculate calorie deficit from your basal metabolic rate BMR , follow the given instructions:. Hi Hamza, Thank you for your feedback! At Oatsy we make sure your data is safe and secure.
