No specific food can guarantee weight loss as I've learned losing weight requires an entire change to a person's eating and exercise plan. Some reasons that people like me use almond flour is that it is low-carb and grain-free. However, it is important to know that almond flour is high in calories. So, if your goal is to lose weight, your entire eating and exercise plan counts. You can consult your healthcare professional or nutritionist for one that works for you.
