Calorie counting can be an effective way to assist in weight management. But it’s also crucial that you choose foods high in essential nutrients, such as fruits, vegetables, whole grains and lean proteins.
Your daily caloric requirements depend on many factors, such as height, weight, sex and activity level. Our calculator uses this information to estimate your daily calorie needs.
Weight loss relies heavily on calories. Our calculator helps determine how many are necessary per day depending on your height, age, gender and activity level. With this data in hand, a meal planner calculates exactly how many should be eaten in each one; most dietitians recommend eating three to five meals throughout the day and spreading out your caloric intake evenly throughout the day.
The calorie calculator follows a framework based on the Mifflin-St Jeor equation and population data; however, additional factors like medications, lean body mass and genetics that impact an individual’s resting metabolic rate must also be taken into account when calculating total daily energy expenditure (TDEE) (1). No matter which formula is chosen, its results provide general guidelines to help individuals maintain or shed unwanted pounds.
To lose weight, the calorie calculator suggests cutting back calories by 20%; this results in an optimal target of 1,200 per day for men and women who are at healthy weights. If they are significantly over-weight, however, then lower caloric intake is recommended – also applicable if they engage in frequent physical activity or exercises regularly.
Calorie counting can be accomplished using simple smartphone apps or by meticulously tracking each food item that is consumed and burned off – both methods provide accurate accounting of calories being taken in and expended to achieve weight loss or maintenance goals. While tracking is more time-consuming and challenging than using apps alone, it remains an effective means of monitoring how many are being ingested and burned off to meet weight loss or maintenance targets.
Planning meals is made easier using the USDA Nutrient Database, which enables users to enter recipes or ingredients and will return calories and nutrition information per serving compared to FDA dietary guidelines. With this database at their disposal, individuals can make more informed choices when selecting food at restaurants and supermarkets alike; additionally, The Environmental Working Group’s Food Scores also give insight into food quality by ranking items based on levels of nutrition, processing, artificial ingredients or both (2).
Carbs (carbs), also known as carbohydrates, are one of the body’s primary energy sources and provide fuel for cells and tissues. After being eaten, carbohydrates are broken down into glucose (a form of sugar) for use by cells throughout the body as energy; any excess is stored as glycogen in muscle fibers and liver cells for later use, or converted to fat storage for long-term storage purposes.
The body meets its glucose needs through eating foods rich in complex carbohydrates such as whole grains, fruits, vegetables and legumes. Complex carbs provide energy while also being an excellent source of important vitamins such as fiber, B6 folate and potassium – and often serve as more satisfying options than simple sugars found in processed food like soda, cookies and juice.
Nutrition guidelines recommend that carbohydrates make up 45-66% of daily caloric intake, with proteins accounting for 10-15% and fats making up the remaining portion. However, certain diets such as keto and low carb diets aim to decrease carbohydrates while replacing them with other sources of fat, protein and fiber.
When selecting carbohydrates-rich foods, seek those with a lower glycemic index (GI). These will be absorbed more gradually into the bloodstream, helping maintain stable blood sugar levels without sudden spikes and dips.
Though there’s no official list of healthy or bad carbs, selecting those high in dietary fiber, starchy vegetables, low-sugar fruits and legumes can help manage blood sugar levels more easily and help you feel full more quickly while losing weight. Eating carbs during exercise is also beneficial because it restores muscle glycogen more quickly so you can begin recovery sooner and be ready for another training session ahead.
Before making significant dietary changes, especially those which aim to lower carb intake drastically, it is strongly advised that you speak to either a registered dietitian or physician first. Cutting carbs drastically may result in fatigue, weakness, headaches and dizziness if done too rapidly; conversely it should also be remembered that carb-rich foods like starchy vegetables, fruit and legumes play an essential part of a balanced diet.
Protein may be best known for building muscle, but this macronutrient serves many other vital purposes in our bodies as well. Protein is vital in creating hormones, enzymes that fuel chemical reactions, hemoglobins to carry oxygen around, building blocks for bones and muscles as well as aiding normal brain functioning and weight management.
This calculator estimates your daily protein needs based on your individual basal metabolic rate (BMR), or how many calories your body burns just to stay alive and perform basic functions such as breathing, circulating blood, digesting food and making energy from food sources such as aerobic exercise and oxygen inhalation. Your BMR depends on factors like gender, age and bodyweight.
After considering your activity level, the calculator accounts for it by following Centers for Disease Control and Prevention/American Dietetic Association recommendations based on your activity level – either light (exercise lightly 1-3 times weekly) or moderate (exercise or play sports 3-5x per week). Finally, the calculator adds up your protein requirements daily in order to give a target number that should be your daily goal.
Your protein goal can be modified based on any changes to your goals or activity levels. Simply click on “Calibrate” to see how it should change.
After you are finished, our complete macro calculator offers an in-depth assessment of your diet including protein, carbohydrates and fat intake.
One final tip: the Recommended Dietary Allowances (RDAs), found on food labels, represent an estimate of what would be needed to prevent deficiency and promote health. Protein has an RDA set at 0.8 grams of protein per kilogram of bodyweight – an extremely low recommendation.
Stick with the advice of experts and muscled gym bros who advise eating at least 1 gram of protein per pound of body weight. While you might not be able to track every last bite, start by weighing or measuring your food for several weeks then entering them into an app or food journal; eventually this will help develop eyeballing portions so you’ll get an accurate sense of how much protein there is in a meal without needing scales!
