When you're not using Portions Master for your whole food meals, drink a healthy and delicious Skinny Pure protein shake. We recommend using Skinny Pure two to three times per day. The Added protein, essential amino acids, and branch chain amino acids from Skinny Pure will help you build lean muscle mass and prevent muscular atrophy from calorie reduction. Muscle loss is definitely not something you want to have happen when you're cutting calories. Muscle burns calories, and muscle loss means slower metabolism, and that can bring your weight loss goals to a standstill. Adding Skinny Pure in between whole meals will help prevent these negative side effects from hampering your progress. You can use Skinny Pure pre- or post-workout, in between meals, before bed, or anytime you need a protein boost.
