IsoFlex is a whey protein powder with quite an impressive amount of branched chain amino acids. Protein powders are ideal for meal replacement during weight loss, but only if there are added vitamins and nutrients to complete the nutritional profile of the powder. There is some vitamin A, vitamin C, iron and calcium in IsoFlex. The vitamin profile is not spectacular, but the powder contains 27 grams of protein for just 111 calories and 0.2 grams net carbohydrates. Will this powder help the dieter lose weight? It could, depending on how the protein powder is used.

Product Features

There is nothing spectacular in the ingredient list. There are sources of milk-based protein, antioxidants, B vitamins, glutamine and chocolate. The company uses sucralose Splenda) to replace sugar and reduce total calories. With 27 grams of protein per serving, the dieter gains a good protein source without packing in the calories. The caloric impact on the diet is low enough that the dieter could use IsoFlex as a snack between healthy meals.

In terms of weight loss, protein is proven to reduce hunger between meals. In one study, men were given high-protein meals and asked to describe hunger between meals. The men were confessed snackers. According to the study, the snacking participants felt less hungry after eating lean protein.

Eating protein to reduce appetite is a tricky choice. If the dieter eats too much protein, the body converts it into carbohydrates. This could cause glucose levels to rise, which could result in hunger. However, if IsoFlex is used as a snack between meals, the dieter should consume just enough protein and feel less hungry at meal time.

IsoFlex is priced higher than other protein powders at $32 per 2-pound container.

Dieting and weight loss is all about balance and healthy food choices. IsoFlex is a bit expensive and the average dieter will have no use for the impressive branched chain amino acid profile, but they could feel less hungry, which is a great thing when trying to lose weight.

    why will the average dieter have no use with the impressive BCAA profile? Is this safe to take for woman?


    Stephen (Editor)

    Due to BCAA’s protein and supposed muscle generating qualities it is included in many bodybuilding supplements. It is for this reason the average dieter wouldn’t find use in it, as they are likely trying to lose weight, not gain it in muscle. Yes, women may take it.
