Examine.com breaks down the recent low-carb vs low-fat study. Their broad takeaway

what it claims

Weight loss does not depend on the elimination of a specific macronutrient or the control of insulin, but is fundamentally based on the reduction of overall energy intake.

The current scientific consensus, supported by extensive meta-analyses (notably Johnston et al., JAMA 2014), confirms that hypocaloric diets lead to similar weight loss regardless of the carbohydrate/fat ratio. While the theory that insulin 'blocks' fat is largely invalidated as a primary mechanism, debates regarding the role of satiety and dietary adherence remain highly relevant. Studies such as those from the Stanford Prevention Research Center (Gardner et al., 2007) show that the success of a diet depends more on an individual's ability to maintain it over the long term than on its strict nutritional composition. It is therefore true that energy balance is the driver of weight change, but it is an exaggeration to say that food choice is unimportant, as certain nutritional profiles naturally facilitate hunger management. The Reddit community shows strong convergence on the principle of caloric intake, while remaining divided on the practical aspects and long-term adherence.

What the graded evidence says

Evidence
B
Effect
ad libitum energy intake as a function of dietary energy density — lowering dietary energy density consistently reduces spontaneous calorie intake at matched food weight/fullness; body-fat change tracks the resulting energy balance
Measured on
general adults

What’s uncertain

Energy balance is the driver, but it's affected by many things (satiety, food quality, sleep, activity), so it's not about rigid calorie math. 'Fat-burning' or 'negative-calorie' foods are a myth.
