A Scientific Analysis of Body Fat Percentage and Basal Metabolic Rate Through Weight Loss Case Studies

Now I'll share a real-life example.

A fan from Dongguan contacted me for weight loss guidance. She recently became a mother, and while happy, she was also a little sad, as she had been pregnant for ten months and had received a lot of "feeding" from her grandparents and other relatives, causing her weight to increase rapidly! She then decided to start losing weight. After two months, she lost 13 pounds, but she didn't know how to understand her true weight loss results, so she asked me to analyze it for her.

Before losing weight, she weighed 68.6 kg; after losing weight, she weighed 62.1 kg, a decrease of 6.5 kg. Her body fat percentage decreased from 33.2% to 30.2%. Calculations show that she lost 4.02 kg of fat. That is to say, of the 13 pounds (6.5 kg) she lost, 8.04 pounds were pure fat, a fat loss rate of 53.6%. From this perspective, this percentage is relatively low. However, through further comparative analysis, we can see that her body fat percentage decreased by 2%, her visceral fat level decreased by 2 grades, and her body age decreased by two years. Simultaneously, her skeletal muscle percentage increased by 1.8%, protein content increased by 0.9%, and body water content increased by 2.11%. In other words, the proportion of fat decreased, and the proportion of muscle increased; her body composition is changing, indicating that the overall effect of this weight loss is quite good.

Regarding the decrease in total muscle mass and the reduction in basal metabolic rate (from 1359 kcal to 1305 kcal), I asked her if she lacked exercise during the weight loss process, leading to significant muscle loss. She told me that she hadn't exercised much. She asked me how to remedy this. I said that for a woman, a basal metabolic rate of 1305 kcal is not low. By increasing exercise, her body fat percentage will continue to decrease, her muscle mass will increase, and her basal metabolic rate will rise to the target level.
