Energy balance

Frequent consumption of takeaway and fast food (defined as eating out or purchasing prepared meals at least once a week) is associated with increased daily energy intake, higher body mass index (BMI), and increased risk of obesity and type 2 diabetes.

Frequent fast food consumption (defined as eating out or buying prepared meals at least once a week) is strongly linked to weight gain and metabolic issues. To mitigate this, limit fast food intake, as even occasional consumption adds significant calories (e.g., +130 kcal/meal) and unhealthy fats. Prioritize home-cooked meals to control energy density and nutrient quality.

GoodSupportsHIGH confidence
consumption of fast food more than once a week increased the risk of being obese by 129%... consumption of fast foods twice a week or more was independently associated with a 31% higher prevalence of moderate abdominal obesity in men and a 25% higher prevalence in women... regular consumption of fast food meals was related to an increased energy intake of 56 kcal/day and 187 kcal/day among adults and children, respectively.
