As South Africans kick off the year with renewed wellness goals, fasting remains one of the most popular approaches for restoring healthy habits. Intermittent fasting, in particular, has been linked to improved insulin sensitivity and weight management. It’s the perfect habit to get your metabolic regulation back on track.
However, when people begin fasting, many experience headaches, fatigue, muscle cramps, brain fog and dizziness. The science suggests these symptoms are often caused, not by fasting itself, but by electrolyte depletion.
Kim Forbes, a functional nutrition coach who focuses on metabolic health, advises clients to replace sodium, potassium and magnesium during a fast. “Most fasting-induced fatigue and lethargy is caused by mineral depletion and low hydration”, she says.
Electrolytes such as sodium, potassium and magnesium are essential for fluid balance, nerve signalling, cognitive function and muscle performance. During fasting, falling insulin levels signal to the kidneys to excrete more sodium and water than usual. This, in turn, increases the loss of other minerals, which is a well-documented phenomenon that contributes to fasting discomfort. The remedy is simple. Experts recommend electrolyte supplementation with a product that contains no calories and no sugar. Doing so provides relief without breaking your fast.
REVIVE is one such product. It is formulated with real, unprocessed Oryx Desert Salt, sustainably sourced from the Kalahari. The salt is rich in naturally occurring trace minerals. REVIVE’s formula provides physiologically appropriate mineral levels without calories, sugar, artificial sweeteners or unnecessary additives, making it particularly well suited for fasting.
Bhauna Hansjee, who conducts regular fasting workshops and hosts a fasting support group that meets monthly in Durban, ensures that every first-time faster has a REVIVE sachet. “Without the electrolyte support, many intermittent fasters fail to complete their fast. Hunger and fatigue can derail anyone”, she adds. “I find that REVIVE makes a significant difference”.
Electrolytes help the body absorb and utilise water effectively, something plain water cannot do alone. Electrolytes that contain no calories remain fully fasting-compliant.
The start of the year consistently sees a rise in fasting adoption for health resets. Research shows that individuals who prepare properly – including electrolyte support – experience more sustainable and comfortable fasting outcomes.
REVIVE encourages South Africans to make electrolytes part of their wellbeing routine for 2026, whether they are fasting for metabolic health, mental clarity, weight loss or autophagy, a type of cellular housekeeping that gets rid of damaged cells.
