Macro partitioning
Takeaway and fast foods are significantly higher in energy density, total fat, saturated fatty acids (SFAs), and trans fatty acids (TFAs) compared to home-prepared meals, contributing to adverse lipid profiles and increased risk of cardiovascular disease.
Fast food is inherently high in energy density and unhealthy fats. A single meal can exceed recommended daily limits for saturated and trans fats. To improve diet quality, minimize fast food consumption and choose meals with lower energy density and healthier fat profiles.
GoodSupportsHIGH confidence
a typical meal purchased from fast food chains tends to be energy dense and contains ~ 236 kcal/100 g, which is twice as high as the recommended energy density of a healthy diet... food (burgers, chicken products, sides or pizzas) purchased from fast food chains contained between 10 and 13 g of total fat and between 3.9 and 4.9 g of SFAs per 100 g.
Why this rating
Supported by chemical analysis of food items and multiple nutritional surveys.

- Trans fatty acids (TFAs) from partially hydrogenated oils, commonly found in fast food, are associated with increased risk of coronary heart disease, systemic inflammation, and adverse lipid profiles (increased LDL, decreased HDL).Strong
- 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.Good

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
