Cooked Leafy Greens

Cooked leafy greens — spinach, kale, and Swiss chard — are the most nutrient-dense calories on this list, delivering over 30% of the daily value for vitamins A and K per 100 grams for just 23–26 calories per 100 grams. A 2023 Harvard Health review shows GLP-1 users often lose key micronutrients as food intake drops, making these greens unmatched for crowding out deficiencies without adding bulk. The word “cooked” matters: raw greens contain about 2 grams of fiber per 100 grams but can feel too bulky on a slow-emptying stomach, whereas sautéing or steaming reduces volume by roughly 70% while concentrating nutrients. They pair effortlessly with all nine higher-ranked foods — stirred into #1 lentil soup, scrambled with #5 eggs, or blended into #7 tofu smoothies — offering gentle regularity with less fiber than oats (10 grams per 100 grams) and almost no protein (only 2–3 grams per 100 grams). Their iron absorption improves with vitamin C, so add a squeeze of lemon, and they remain a supporting actor that turns a single-protein plate into a complete one.
