This is how calorie calculator for weight loss creates your complete calorie and nutrition plan.
Calculate Calories for Weight Loss
The most important aspect of weight loss is creating a calorie deficit. This means that you are consuming fewer calories than you are expending.
Generally, eating 7700 calories less will result in a 1 kg weight loss. So creating a 500 calorie deficit per day will result in a weight loss of about 0.5 kg per week.
With the Lose weight calorie calculator, you can see how many calories you should eat per day to account for this deficit.
It also works as a safe weight reduction calculator—where you plan to lose fat slowly without cutting too many calories.
Calculate Macros for Weight Loss
When losing weight, it's important to know not only calories, but also your daily macro (protein, carbohydrates, fat) ratio.
Protein protects muscle, carbs provide energy, and fat helps with hormone regulation and cell function.
Using the Macro calculator for weight loss, you can find out how to divide your macros according to your body type and goals.
Many people want to know how to calculate macros for weight loss—this calculator provides the answer easily.
Calculate Protein for Weight Loss
Protein is important to prevent muscle loss during weight loss. In general, it is correct to consume 1.6–2.2 grams of protein per 1 kg of body weight.
Our protein calculator for weight loss calculates how much protein you need per day.
