One of the latest approaches to weight loss is based on the weight and bulk of the food you consume, not the makeup of the diet. Studies suggest that people eat the same volume of food each day, so instead of the volume of food being the focus of a weight loss regimen, the calorie intake should be the entire focus. Such is the rationale behind several new diet books, including "Volumetrics" by Barbara Rolls, a nutrition and obesity researcher at Pennsylvania State University, and a new version of the Pritikin Principle diet called the Calorie-Density Solution.
You calculate the calorie-density of an item of food by dividing its calories by its weight. Foods with lower calorie densities are better for losing weight than foods with high-calorie densities. Foods with low-calorie densities are high in fiber and water, which add calorie-free volume and weight. Such foods include vegetables, fruits, and whole grains. Combining these foods with high-calorie density foods like pasta or meat can lower the general calorie density of a meal thus making it healthier
In an experiment conducted at Penn State, researchers gave women similar meals but varied the ingredients to change the calorie densities. For example, some women were served a pasta dish on two days, but on another day they were served a lot of vegetables to lower their calorie density. The women ended up eating the same weight of food each day, but when they ate lower-density meals they consumed 30% fewer calories. The results may have shown a correlation between lower density food intake and weight loss, but the study was a bit short-term. Long-term studies are being conducted to learn more.
It seems pretty much common sense to me that a decrease in caloric intake and eating healthier will lead to weight loss. Complicated books and theories are not needed to be studied to learn the obvious.
calorie burn calculator
This calorie calculator is based on multiple equations, and the calculator's results are based on an approximate average. The Harris-Benedict equation was one among the earliest equations wont to calculate the basal rate (BMR), which is that the amount of energy consumed every day at rest.
To be more accurate, it was amended in 1984 and was used until 1990, when the Mifflin-Saint-J equation was introduced. The Mifflin-Saint-Xavier equation also calculates the BMR and is far more accurate than the revised Harris-Benedict equation.
Catch - The Macardell formula is somewhat different in that it comfortably calculates daily energy expenditure (RDEE), which takes into account lean body components, a task that neither Muffin St. Georges nor Harris-Benedict equate. Are Of these equations, the Mifflin-Saint-Xavier equation is considered the most accurate equation for the exception to the BMR calculation that the Ketch-McCardel formula may be more accurate for those who are lean and know the percentage of body fat.
The three equations employed by the calculator are listed below.
Mifflin-St Jeor Equation:
BMR = 10W + 6.25H - 5A + 5
BMR = 10W + 6.25H - 5A - 161
Revised Harris-Benedict Equation:
BMR = 13.397W + 4.799H - 5.677A + 88.362
BMR = 9.247W + 3.098H - 4.330A + 447.593
BMR = 370 + 21.6(1 - F)W
Where 'W' is Man / Woman body weight in kg
H is Man Woman body height in cm
A is age of Man / woman
F is body fat in %
