Calculate Your Fat Loss

Role of fat shedding in weight-loss

Overweightness and obesity are burgeoning problems in today's times. Owing to the various health risks they bring along viz. heart ailments, diabetes, and musculoskeletal disorders, losing weight has become a global preoccupation.

However, the process of weight-loss should essentially aim at shedding the excessive accumulated fats, which absorb calories and water, thus making you sluggish. It is important to remember that the body's weight is a sum total of the bones, muscle, fluid, and fats. The weight-loss should not lead to loss of muscle and even the essential fats which're required to absorb fat-soluble vitamins and protect our internal organs.

Thus, one should consult trained professionals to chalk out a proper nutrition plan and exercise regime that'll take into consideration other factors like your gender, age, level of physical activity, your BMI, and your BMR.

Crash diets, fad diets, and improper or excessive exercise will only lead to other complications like chronic fatigue, low endurance, injuries, and heart complications.

How to differentiate between fat loss and muscle loss?

In the pursuit of trying to lose weight, it is easy to ignore paying attention to whether the weight is being shed owing to loss of muscle, or loss of excess fat. An easy way to gauge if you're suffering from muscle loss is to observe if you feel constantly tired, or find it difficult to pick up heavy things.

To determine if you're indeed cutting the excessive flab in your weight-loss regime, the easiest way is to measure if you're losing inches around your waist and hip.

You can also use the skinfold measurement method for this purpose.

Body fat scales that use bioelectrical impedance analysis (BIA) method to map your body composition, are also a good way to gauge how much fat have you lost. The advantage of using body fat scales is that since it also maps the other constituents that make up body-weight, it can tell you whether you are losing fat or muscle in your weight-loss regime.

How to calculate body fat percentage loss?

Body fat loss calculators consider a person's present weight, height, age, gender, and level of activity to calculate how much fat you have lost, or need to lose. They use the Harris-Benedict formula, or the Katch-McArdle formula for this purpose. The latter is preferred over the former because it also considers lean body mass.

The Katch-McArdle formula estimates the Basal Metabolic Rate aka BMR in the following way: BMR = 370 + (21.6 * Lean Body Mass[kg]). The lean body mass is calculated as LBM = (Weight[kg] * (100 - Body Fat %)/100. The body fat can be calculated by the various methods ranging from skinfold measurement to BIA.

The BMR calculated with this formula can elucidate the number of calories that person requires to keep functioning properly. On the basis of this info, a nutritionist can easily calculate the fat loss, considering 1 pound (450 gms) of fat is equal to 3500 calories. Rebalancing the calories in your intake to preserve muscle mass and shed excessive fats, can help you lose weight the healthy way.

Calculate macros for fat loss by determining your daily calorie needs, then allocating a percentage of those calories to protein, carbohydrates, and fats based on your goals and activity level.

A fat loss calculator estimates your daily calorie needs based on factors like age, gender, weight, height, activity level, and desired rate of weight loss. It then suggests a calorie deficit and macronutrient breakdown to support fat loss.

Fat loss calculators can provide a rough estimate, but accuracy may vary depending on the formula used and individual factors such as metabolism and body composition.

While fat loss calculators can estimate calorie deficits and potential weight loss, actual results may vary based on individual factors like adherence to the plan, metabolic rate, and body composition changes.

A safe and sustainable rate of fat loss is typically 0.5-1 kg (1-2 lbs) per week. Rapid weight loss can lead to muscle loss and other health issues.

Calculate body fat percentage loss by comparing measurements before and after a period of fat loss using methods like skinfold calipers, bioelectrical impedance analysis (BIA), or DEXA scans.

Calculate protein intake for fat loss by aiming for 1.6-2.2 grams of protein per kilogram of body weight per day to preserve muscle mass while in a calorie deficit.

Fat loss calculators typically consider factors such as age, gender, weight, height, activity level, desired rate of weight loss, and sometimes body composition to estimate daily calorie needs and macronutrient breakdown.
