And that would be great, if true.
What helps lose weight is negative calorie balance, whether a result of diet or xerecise, or both.
No lean food will make you lean.
Think of foods that give you energy and building blocks for your body, mainly protein and fat, throw in some fruit and veggies for color, eat carbs on holidays and you'll be fine. keep track of your calories, keep a food log and exercise regularly, results will come. Good luck!
