  • New and Improved! Lean Science -- Inspired by the Science Behind Meal Replacement Shakes

    Are you looking for a healthy and sensible way to slim down, get healthier and manage your weight? Are you tired of settling for lackluster meal replacements that taste bland, chalky and leave you still feeling hungry? The search is over! Purity Products' all new Lean Science® meal replacement shakes are in a league of their own in terms of flavor, quality and satiety -- and they have to be tasted to be believed. Research on weight loss shows that partial meal replacements can be more effective strategies for weight loss than trying to follow a reduced calorie diet. The scientific publication International Journal of Obesity documented this in a 2003 meta-analysis of six clinical studies. (Reference: Heymsfield SB, et al. Weight management using a meal replacement strategy: meta and pooling analysis from six studies Int J Obes Relat Metab Disord. 2003 May;27(5):537-49.)

    With Lean Science® you can enjoy an amazing taste and creamy texture of a Meal Replacement Smoothie while you nourishing your body with essential vitamins, minerals, protein, fiber, a clinically-researched probiotic and more. With Lean Science you choose whether you want to replace 1 or 2 meals a day. If you want to lose more weight, consider replacing a breakfast and a lunch… if you just want to manage your weight, maybe lose a few pounds, use Lean Science to replace 1 meal per day.

    We all know that one of the big keys to losing weight is cutting calories. Lean Science® makes cutting those calories simple, affordable and delicious. Just enjoy a shake for breakfast, and/or a shake for lunch.... and a sensible, well-balanced dinner and let Lean Science go to work for you. When you replace a meal with Lean Science, it helps you stay satiated and feel satisfied, so you can "put calories in the bank". Saving calories can lead to weight loss. Lean Science® meal replacement shakes are scientifically engineered with healthy fiber, Whey protein plus 25 essential vitamins and minerals, to nourish you while filling you up at the same time so you can cut back on your caloric intake and achieve your weight loss goals. Along with the satiety benefits of a meal replacement shake, Lean Science® is power packed with an innovative and delicious blend of:

    NEW and IMPROVED Lean Science Meal Replacement -- 5 key factors:

    • Now Enhanced with 15 grams of Healthy Whey Protein + a Satiety Support Blend
    • 7 grams of Fiber featuring a Prebiotic Fiver Blend with Glucomannan
    • 24 Vitamins & Minerals with a new Richer, Creamier flavor
    • A Clinically-Researched Probiotic (1 Billion CFU / serving)
    • Fruit and Vegetable Proprietary blend with Apple, Kale, Blueberries and more

    Lean Science is Nutrition Packed

    What sets Lean Science® apart is its unique and innovative formula. Not only is each serving size only 170 calories, (about 260 calories with milk), but those calories are action-packed. We believe that healthy weight loss and management means nourishing your body with what it needs to function optimally while continuing to shed those unwanted pounds. Our formula helps you slim down while you cut calories yet still feel satisfied. Rest assured that we follow the science!

    15 Grams of Healthy Protein

    Whey protein is a complete and digestible protein. It contains all of the essential amino acids that the body needs for strength and repairing muscle tissue. Whey protein helps the body build muscle while maintaining lean muscle mass, especially when combined with a resistance exercise program. A recent study reported in the Journal of the American College of Nutrition concluded that individuals who consumed whey protein as part of a weight loss management plan saw overall improvements in body composition. (Reference: Miller PE, et al. Effects of whey protein and resistance exercise on body composition: a meta-analysis of randomized controlled trials. J Am Coll Nutr. 2014;33(2):163-75.)

    24 Essential Vitamins and Minerals

    Fueling your body with essential nutrients is an enormous component in managing healthy weight loss. Vitamins and minerals perform hundreds of roles in the body helping to keep us healthy and happy. The Lean Science® formula is intelligently designed with about 25-35% of the RDA with vitamins and minerals as a good meal replacement should be -- to support our bodies' needs. Note: For those wanting to limit their intake of iron Lean Science has just 15% of the RDA in the Chocolate version and 2% in the Vanilla version.

    New & Improved Prebiotic Fiber Blend - 7 Grams

    A healthy intake of fiber helps you feel fuller and more satisfied when you're trying to eat less. The New & Improved Lean Science Prebiotic Fiber Blend features gum acacia and glucomannan. Gum acacia has been shown to reduce intake of calories. In a study reported in the scientific journal Appetite, volunteers who consumed five or ten grams reduced their caloric intake by 60 calories and reported increased feelings of satiety. (Reference: Calame W, Thomassen F, Hull S, Viebke C, Siemensma AD. Evaluation of satiety enhancement, including compensation, by blends of gum arabic. A methodological approach. Appetite. 2011 Oct;57(2):358-64.) Gum acacia fiber also serves as a prebiotic, helping to maintain a healthy balance of probiotics in the gut. Prebiotics serve as food and fuel for probiotics, the beneficial friendly flora vital to gut ecology. Glucomannan is plant-derived, water soluble fiber that can absorb up to 50 times its weight in water, which helps promote satiety and the feeling of fulness after meals.

    Probiotic: Gastrobacillus™ Bacillus Coagulans

    Probiotics serve as one of the body's first lines of defense. They maintain healthy digestion, support immune function in the gut, and diligently work to eliminate toxins from the body. Lean Science® contains 1 Billion CFU Bacillus coagulans per serving. This is an especially hardy and shelf-stable probiotic. Bacillus coagulans has been the subject of numerous studies and has demonstrated its abilities to support healthy elimination, help maintain the population of friendly flora, and relieve occasional gas and bloating. This special probiotic has also been proven to aid in regulating bowel movements. (Reference: Minamida K, et al. Effects of dietary fiber with Bacillus coagulans lilac-01 on bowel movement and fecal properties of healthy volunteers with a tendency for constipation. Biosci Biotechnol Biochem. 2015;79(2):300-6.)

    Multi-Factorial Satiety Blend

    This special Multi-Factorial Satiety Blend is a healthy combination of our premium Whey protein, AcaciaBiotic™ Prebiotic Fiber, Healthy fats (based in coconut oil). This advanced appetite controlling blend helps you to feel fuller longer (satiety) and reduces cravings. This will help curb your desire to snack throughout the day. The more satiated you feel, the more energy you have to power through our day and manage your caloric intake.

    TASTE and SATIETY TIP: Lean Science tastes great just mixed in cold water and delivers about 170 calories. Enjoy our Utterly Decadent Chocolate or Ice Cream Vanilla flavors. Both are exceptional! Many people also add Lean Science to their favorite milk and mix in a shaker cup enjoying how well it whips up into a creamy, rich, super-delicious smoothie. Regular milk can also boost the satiety effects of Lean Science by adding about 8 extra grams of protein and about an extra 90 calories - roughly 260 total.

    Once you begin to incorporate Lean Science® into your life, you will see and feel amazing changes within your body. Our Lean Science® shakes will leave you feeling lighter, more energized, and (most importantly) satisfied.

    Just imagine...

    • Feeling stronger
    • More Lean Muscle, Less Fat
    • Supporting your immune system with whey protein
    • Having increased energy
    • Having reduced urges to snack
    • And feeling less bloated

    ...all while losing weight! As with all weight loss meal replacement programs, to ensure success be sure to enjoy a sensible, nutritious and well balanced meal for the meal(s) you consume. Moderate exercise and healthy sleep are key factors that also will help ensure your Lean Science program helps you achieve your weight loss goals.
