First, because many people switching to a WFPB diet initially have a hard time getting enough calories, e.g. they may start by eating lots of salad, and not get enough calories, and wonder why they’re often hungry/tired. It takes time to research and understand what fruits, vegetables, legumes, and other ingredients deliver the most nutrition, so we solve that problem for them.
Second, because LeafSide’s core value is healthy convenience: Thus we deliver a truly complete, organic foods meal (not a snack) that’s ready in minutes. Most other “meal” services will charge you more while only giving you a third of the calories (e.g. 250 kCal) and nutrition (e.g. only a handful of ingredients, instead of our 20-30) — and that’s simply not enough for a real meal.
So we designed our meals to be as calorie/nutrient-dense as possible: Currently if you pair any two meals this comes out to roughly 1300-1500 calories. That still leaves most people plenty of extra room for a 3rd meal each day, or snacks, if still desired.
Finally, remember that calories are often not equal: 500 calories of donuts and soda has an entirely different effect on your body compared to 500 calories of vegetables, fruits, legumes, nuts, seeds, whole grains, etc. Most people eating a complete WFPB diet find they don’t really need to count or worry about calories, as the ample fiber in the diet naturally regulates feelings of hunger and satiety. When eating whole plant foods, the body’s natural wisdom takes over to reach a healthy state — as the old (pre-soda, pre-candy-bar) Zen saying goes, “When you’re hungry, eat; when you’re tired, sleep. Fools will laugh, but the wise shall understand.”
