Our brain constantly monitors how much we should weigh and automatically regulates this for us by changing our cravings, appetite and sense of fullness.

When you are trying to lose weight, these are the key side effects that are known to make someone’s weight loss journey harder. Modius makes the whole process easier by stimulating the vestibular nerve which we know influences the hypothalamus and brain stem to reduce your cravings and appetite.

To understand more about the key side effects associated with losing weight and where Modius comes in, simply read on, watch our CEO explain in the video below and even check out our research papers.


Taste, cravings and food choices are influenced by the area of the brain stem called the parabrachial nucleus.

A common finding when people try to lose weight is that cravings for carbohydrates increase. This is especially true when the body is under stress making it harder to resist snacks and excess calories.

Modius targets your cravings by reducing your desire for carbohydrates making it easier to resist high calorie snacks.


The hypothalamus regulates appetite by receiving feedback from hormones such as leptin, insulin and ghrelin.

The hypothalamus uses this feedback to automatically control your hunger. However, when body weight goes down the hypothalamus unfortunately increases appetite significantly.

Modius targets your appetite during this time by controlling your appetite and stopping it from increasing significantly when you are trying to lose weight.


This area of the brain stem is called the nucleus of the solitary tract. It automatically regulates fullness by monitoring signals from the gut and hormone levels in the blood. It is this part of the brain that determines portion size and lets you know when you are full.

When losing weight, it is this area of the brain stem that often leads to someone never feeling satisfied and typically results in overeating.

Modius targets your feeling of fullness which should leave you feeling satisfied quicker and stop you overeating.
