Leiner Starchaway is a starch or carb blocking supplement. Dieters take the supplement before meals that contain carbohydrates or starches. The ingredients “block” the carbohydrates from being digested. These supplements do not block carbohydrates as the companies would like the dieter to believe, but they do keep carbohydrates a larger size so they digest more quickly. This reduces the impact of carbohydrates or starches on the body and thus could reduce hunger associated with carbohydrate metabolism.

List of Ingredients

Sugar, Corn Syrup, White Kidney Bean Extract Phase 2 Brand, Partially Hydrogenated Coconut Oil, Xylitol, Corn Starch, Glycerin, Natural Flavor, Citric Acid, Soy Lecithin, Carrageenan, Malic Acid.

Product Features

Leiner Starchaway contains several ingredients uncommon in weight loss or starch-blocking supplements. These ingredients are included because the supplement is delivered in soft-chew form. The dieter must chew 12 soft chews before starchy meals. This is a huge number of soft chews to consume. There are other starch-blocking supplements with the same active ingredients and zero calories.

Sugar and corn syrup are used to sweeten the soft chews. These ingredients add unneeded calories. White Kidney Bean Extract Phase 2 is the only active ingredient. This is the ingredient that prevents carbohydrates from breaking into tiny pieces during digestion. When carbohydrates stay long, the body processes them more quickly and moves the carbohydrates out of the body. Manufacturers claim this causes the body to absorb fewer calories. This may be true, to an extent, but it does not eliminate the carbohydrate calories.

Leiner Starchaway supports a healthy diet and exercise program for weight loss. Dieters should be eating healthy before starting a supplement, because supplements are not miracle drugs. If a supplement claims to produce weight loss without changing diet or adding exercise daily, step away from the product and find one that supports healthy life choices.

Leiner Starchaway is an interesting supplement in soft chew form. There are plenty of starch-blocking supplements that come in capsule or tablet form that contain no calories and require only one pill before a meal. The active ingredient does have clinical backing, so the dieter can rest assured Leiner Starchaway will have some effect on the body, but that effect is not a total blocking of carbohydrate calories.

If the dieter does not eat right and exercise, the effect of the supplement will not be noticeable on the scale.
