Avocado

Avocado is the highest-fat food on this list, and that is by design. Not all fat is equally problematic for GLP-1 users — the issue with high dietary fat on these medications is primarily saturated fat and the overall fat load of heavily fried or processed foods. Avocado provides predominantly monounsaturated oleic acid, the same fat that gives olive oil its cardiovascular profile, in a format that is easier to tolerate and significantly more nutrient-dense. A 100-gram serving of avocado provides 7 grams of fiber, 3 grams of protein, and 160 calories, with a micronutrient profile that is exceptionally relevant for GLP-1 users. Avocado is among the richest dietary sources of potassium — providing roughly 14% of the daily value per 100 grams, compared to 10% for a banana — addressing what NIH research identified as one of the two most prevalent deficiencies in GLP-1 user populations (potassium deficiency at 98.6%). It is also a meaningful source of magnesium, folate, vitamins K, E, and B6, and copper. The fat content in avocado serves a satiety function that complements GLP-1 therapy. Dietary fat slows gastric emptying and triggers cholecystokinin release — a satiety hormone that operates through a different pathway than GLP-1 — providing a dual satiety mechanism. Adding half an avocado to a meal can meaningfully extend fullness for two to three hours without spiking blood sugar. Avocados also support fat-soluble vitamin absorption from other foods eaten in the same meal. The vitamins A, D, E, and K present in salmon, eggs, and leafy greens require dietary fat for proper absorption — making avocado a functional companion ingredient, not just a standalone food. At $0.75 to $1.50 each depending on season, they remain accessible on a regular basis.
