Losing weight on junk food doesn't fix fat tissue inflammation
Caloric restriction-induced weight loss with a high-fat diet does not fully recover visceral adipose tissue inflammation in previously obese C57BL/6 mice.

Mice got fat eating high-fat food, then lost weight either by eating less junk food or switching to healthy food. Both lost the same weight, but only the healthy-food group fully healed their fat tissue inflammation.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Improvements in metabolic markers and weight loss observed on extreme low-carb or carnivore diets are primarily attributable to caloric restriction and elimination of ultra-processed foods, not to the physiological properties of animal-based foods alone.
Even when obese mice lose weight by eating less on a high-fat diet, their belly fat stays inflamed — unlike mice that eat a healthy low-fat diet, whose inflammation goes away.
When obese mice lose weight by eating less on fatty food, their belly fat stays more inflamed than when they lose weight eating healthy food — even if they weigh the same.
When obese mice eat less on a high-fat diet, they lose belly fat and their fat cells shrink just as much as mice eating a low-fat diet — even if the high-fat group still has more inflammation.
