Avocado

Avocado is the highest-fat food on this list by design, providing monounsaturated oleic acid that supports GLP-1 users better than #7 Berries' low-fat profile or #6 Cottage Cheese's casein. A 100-gram serving delivers 7g of fiber, 3g of protein, and 160 calories, with potassium at 14% DV—addressing the 98.6% deficiency rate in this population, compared to bananas' 10% DV. Its fat triggers cholecystokinin release, a satiety signal via a different pathway than GLP-1, extending fullness 2–3 hours without blood sugar spikes. Avocados also enhance absorption of fat-soluble vitamins from foods like salmon and eggs, acting as a functional companion ingredient. At $0.75–$1.50 each, they are an accessible source of magnesium, folate, vitamins K, E, B6, and copper, supporting metabolic and bone health during calorie restriction.
