Two outlets report that widely used calorie-counting approaches may not always support weight loss. They cite evidence suggesting that repeatedly restricting food based on calorie totals can increase hunger and may reduce how many calories the body burns, a process often described as lowering metabolic rate. One account frames the issue through a personal case study narrative involving a nutritionist who gains weight after trying to cut calories, though the details provided in the summaries focus more on the claimed physiological impacts than on specific methods or verified measurements. Across the sources, the central point is that “calories in, calories out” may not fully capture how dieting affects appetite and energy expenditure for some people. Both summaries also emphasize that calorie-counting can lead to unintended outcomes, rather than functioning as a straightforward tool for weight control. The articles therefore present calorie counting as potentially counterproductive in certain circumstances, particularly when it drives persistent hunger or metabolic adaptations that make weight loss harder.
