1. What is in LeanMeal RS?

LeanMeal RS is a nutritionally balanced meal replacement shake that is low in calories (120-130 calories per serving when mixed with water) and low in sugar (1 gram per serving). The drink mix is naturally sweetened with a combination of stevia, monk fruit and Zerose, a non-caloric sugar alcohol. LeanMeal RS is formulated with 18 grams of whey protein to support lean muscle mass. Each serving also contains 8 grams of Fibersol-2® resistant starch, a type of prebiotic fiber that slows the rise of blood sugar, increases satiety, and promotes a healthy weight.

2. What is the benefit of LeanMeal RS?

By their portion control, meal replacements are an effective weight loss tool. As numerous studies have shown, meal replacements used as part of a calorie-restricted diet have been found to safely promote more weight loss and fat loss than a calorie-reduction diet alone. Meal replacements are also very effective at maintaining weight loss. LeanMeal RS is the perfect solution for those busy days when you just don’t have time to eat a healthy meal or when you want to get a nutritional boost without having to worry about deviating from your eating plan.

3. What makes LeanMeal RS better than other meal replacement brands?

Many meal replacements are available, with powder or ready-to-drink being the most popular forms. Despite being marketed as “diet” products, many well-known brands contain large amounts of sugar and not much protein. Each serving of LeanMeal RS delivers 18 grams of high-quality whey protein plus 8 grams of Fibersol-2® prebiotic fiber. Based on taste tests conducted at our lab, participants found that many popular meal replacement drinks neither mixed well nor tasted good. In comparison, LeanMeal RS comes in two delicious flavors and has less than 130 calories and fewer than 2 grams of sugar per serving.

4. What is the difference between LeanMeal RS and a regular protein powder?

Most protein powder supplements are formulated with either just a plant or animal protein or a combination source. Protein powders can vary in taste and price depending on the protein source used. Whey protein concentrate and whey protein isolate are more expensive due to their very high protein content (85-95% versus less than 70% for vegetable proteins). LeanMeal RS is more than just a protein supplement. As a meal replacement, LeanMeal RS provides balanced nutrition, formulated with 18 grams of whey protein concentrate, 8 grams of Fibersol-2® resistant starch fiber, less than 2 grams of unsaturated fat, plus 25% of Daily Values for 24 vitamins & minerals per serving.

5. Who should use LeanBiotics LeanMeal RS Meal Replacement Drink Mix?

Anyone who is looking to attain and sustain a healthy weight over the long-term can benefit from taking LeanBiotics LeanMeal RS Replacement Drink Mix.

6. Who should not use LeanBiotics LeanMeal RS?

Nutritional supplements have an excellent safety track record. However, certain individuals should seek the advice of their doctor before beginning a weight loss program, particularly diabetics and those with any health issues. Please refer to the Directions section on the product label for more information on warnings and contraindications.

7. Can I use LeanMeal RS if I am lactose intolerant?

Individuals with lactose intolerance lack the enzyme lactase which helps break down lactose, a sugar found in milk and other dairy products. LeanMeal RS contains whey protein concentrate, a high-quality protein derived from milk (whey is the liquid portion of the milk that separates from the curds). When whey protein concentrate is made, most of the lactose is removed. Even though some lactose remains, whey protein is typically well-tolerated by those with lactose intolerance.

8. Can I use LeanMeal RS if I’m gluten sensitive or soy sensitive?

LeanMeal RS is a gluten-free product so anyone with gluten sensitivity can take the product without any problems. The whey protein formulated in LeanMeal RS contains a trace amount of soy lecithin (less than 1% of the product formulation). Depending on the level of soy intolerance will determine if an individual can take LeanMeal RS.

9. LeanMeal RS contains 18 grams of whey protein. Why is protein important to weight loss?

If your goal is to lose weight, then incorporating more high-quality protein into your diet is your best bet. Numerous studies have demonstrated that protein is more satiating than either carbohydrates or fat. This helps to keep you feeling full between meals. In addition, higher protein diets, in conjunction with regular exercise, are associated with increased thermogenesis (raising your metabolic rate) and retention of muscle mass. By modestly increasing your protein intake, while controlling total calories, you can improve body composition, facilitate fat loss, and improve body weight maintenance after weight loss.

10. LeanMeal RS is formulated with whey protein concentrate. Why is this type of protein used versus a plant protein?

Whey protein concentrate is 80% protein which is considerably higher than plant proteins such as soy or rice. Because whey is packed full of branched-chain amino acids (BCAAs) – leucine, isoleucine, valine – it may help preserve lean muscle tissue between workouts or when dieting. While high in protein content, whey protein is low in carbs, fat, and calories. Whey protein also digests more easily than other proteins.

Solid research suggests that by supporting satiety, reducing caloric intake, promoting fat burning and boosting lean body mass, whey may benefit individuals trying to achieve or maintain a healthy weight. Evidence supports consuming whey before meals may help limit subsequent hunger and food intake, and that ingesting whey before exercise may enhance the fat-burning effects of the workout.

11. LeanMeal RS contains 8 grams of Fibersol-2. What is Fibersol-2 and how does it help with weight loss?

Fibersol-2® is a special type of soluble fiber called resistant starch. Soluble fiber slows the emptying of the stomach which in turn slows the rise of blood sugar and increases satiety. The type of soluble fiber used in Fibersol-2® not only promotes a healthy weight but as a prebiotic fiber supports the growth of “lean” bacteria.

12. What type of sweetener is used in LeanMeal RS? Why aren’t artificial sweeteners used?

LeanMeal RS has minimal added sugars – just 1 gram per serving. The drink mix is sweetened with a combination of stevia, monk fruit extract and Zerose™, a type of sugar alcohol that has zero calories. Unlike LeanMeal RS, many diet products are formulated with artificial sweeteners such as Equal, Splenda or Sweet ‘N Low which have been complicit in numerous studies suggesting an association between their use and weight gain, and an increased risk for type 2 diabetes. A study published in September 2014 confirmed that consuming artificial sweeteners change the composition and function of the gut microbiota. Given the importance of a balanced microbiome in achieving and maintaining a healthy weight, not using artificial sweeteners is prudent.

13. Each serving of LeanMeal RS contains 25% of Daily Values for vitamins and minerals. Does this mean I can skip taking my regular multi-vitamin & mineral?

Ideally, you should be obtaining all the key vitamins & minerals from the foods you eat. However, if you’re cutting back on calories or food, this can be difficult. Given that a meal replacement is intended to replace a meal, it makes sense that the product is formulated with at least 25% of the daily values for vitamins & minerals. Even if you eat a wide range of fruits and vegetables for the remaining two meals, you might still be deficient in certain micronutrients. Taking a high-quality supplement such as VitaMedica’s Multi-Vitamin & Mineral can help to fill in gaps in your diet.

14. How often should I have my LeanMeal RS?

The recommendation is to use LeanMeal RS as a partial meal replacement, or in other words as a replacement for just one meal per day. Typically, most dieters opt to use LeanMeal RS in the place of breakfast or lunch as it is a quick and convenient alternative compared to dinner. Select the meal to replace that makes the most sense for you. For the remaining two meals, you’ll eat a healthy, balanced diet, following the dietary recommendations outlined in the LeanBiotics Healthy Weight Loss Plan.

15. Can I mix my LeanMeal RS ahead of time?

Yes. You may portion out one or more servings of LeanMeal RS and store in the refrigerator for up to one week. Be sure to mix well prior to consuming.

16. What’s the best way to prevent the LeanMeal RS drink mix powder from getting lumpy when mixed with liquid?

The best way to prevent lumps from forming is by using the LeanBiotics Classic Blender Bottle (sold separately). The bottle includes a patented wire whisk ball which is superb for preventing the formation of clumps. When making your drink, start by adding 8 oz. of liquid, add the LeanMeal RS powder, then drop the wire ball into the bottle. Close the lid tightly, including the spout cover, and shake for about 30 seconds. The result should be a smooth, great-tasting shake without any lumps!

17. How long can I stay on LeanMeal RS?

Because the combination of vitamins, minerals, fiber, and protein in LeanMeal RS provides balanced nutrition for both you and your microbiome, you can continue to stay on the product for as long as you like.

18. Will I lose more weight if I replace more than one meal a day with the LeanMeal RS?

While it is possible you will lose more weight by replacing more than one meal a day with LeanMeal RS, you should consult with your doctor before doing so. It is important to feed your body and your microbiome with the essential nutrients it needs through wholesome foods like fruits and veggies, nuts, beans, lean protein, and quality carbohydrates throughout the day.

19. After LeanBiotics LeanMeal RS, what other VitaMedica supplements should I take?

Much will depend on your health, wellness, and weight management goals. But, if you’re looking to maintain a healthy, balanced microbiome over the long-term, continuing with LeanBiotics Probiotic daily and incorporating LeanMeal RS as a meal replacement or a healthy mid-meal snack is ideal. Dr. David H. Rahm, VitaMedica’s founder and medical director, recommends adopting a health-promoting diet rich in fruits, vegetables and high-quality protein and fat sources as the best first step to improving your health and wellness. VitaMedica’s nutraceuticals are designed to help cover any nutrient gaps that may remain, and target specific health objectives.
