What the……??!! Your body weight is the sum weight of your organs, bones, muscle, soft tissue, etc. Weight loss simply takes into account a drop in this sum. Your BFP is the weight of body fat relative to your total body weight. Therefore, fat loss would result in a lower body fat percentage. How does that explain an increase in BFP concomitant to a decrease in body weight? That would happen if part of the weight loss comes from a loss of muscle. If BFP is the weight of body fat relative to total body weight, your total body weight kg less the amount of body fat kg leaves you with your lean body mass LBM.

Researchers believe these gaining may somehow alter the growing baby’s metabolism in ways that show up later in life. A positive result, from people they are genetically inclined to stay fat, might be self-fulfilling. If you’ve ever said something like “I want to tone weight or “I want to lean out,” you were referring to but recomposition, even if you didn’t know it. Experts say it’s a combination of increased availability, losing portions, and more high-calorie fat.
