The Best New Snack? Biscuit With Whey Protein

Obesity and its related complications are some of the most serious public health concerns around the world nowadays.

It’s a medical problem that significantly increases the risk of diseases such as diabetes, hyperglycemia, and hypertension, among others.

The physiologic factors responsible for the maintenance of body weight are peripheral hormones, like insulin and leptin, and several gastrointestinal hormones that regulate appetite.

Additionally, physiological and psychological disorders may also influence food intake and disturb the balance in the body.

Therefore, a possibly effective strategy to control, prevent, and treat obesity is to consume foods that have the ability to control appetite and food intake.

A newly published study has possibly found a potential food ingredient that has this effect - whey fortified biscuits.

What’s Important

Foods that have similar calorie counts but different macronutrient compositions will inevitably have different satiety responses - some keep you full for longer and others won’t.

In this case, we’re interested in the ones that can keep you full for longer because then your appetite will be under control, and your overall calorie intake will be lower.

Proteins are the most satiating, while fats are the least.

The type and quality of protein also determine its ability to affect appetite.

It’s known that whey protein is the most effective in regulating the feeling of hunger, compared to other types of protein, like casein (a protein found in milk) and soy.

The Details

This study aimed to create a more nutritious product that would be a suitable substitute for other snacks of this kind that are high in sugars, fats, and salts.

Thereby, the scientists conducting this study wanted to assess the effects of a biscuit fortified with whey protein, and examine the effects on energy intake, appetite, and weight loss in overweight or obese individuals.

The participants were healthy adults between the ages of 20-50 years, and they were given a 50g of biscuit fortified with 12.05g of whey protein per day for 8 weeks.

The results were the following:

  • Most importantly, whey-fortified biscuits could reduce appetite;
  • Energy intake, body weight, BMI, and waist circumference were all reduced following consumption of whey-fortified biscuits;
  • Body fat was also reduced, as well as the intake of carbs, leading to lower postprandial insulin (rise of blood sugar following a meal);
  • Levels of insulin in the blood were also lowered.
  • Bottom Line

    This study shows some promising results in regards to creating a healthier version of conventional biscuits, with some added health benefits.
