Hydration while losing weight on GLP-1s

Ever feel kind of off while losing weight, even when everything seems to be working?

We hear this a lot from people who are eating less or using GLP-1s. In many cases, it comes back to something simple that gets overlooked.

Hydration isn't just about water. When you lose weight, your body naturally loses water and electrolytes at the same time. This can happen from eating less, lowering carbs, or changes in how your body stores fluids.

That shift can leave people feeling low energy, lightheaded, or just not quite right, even if they are drinking water consistently. Part of the reason is that you are likely getting fewer minerals from food, and in some cases your thirst signals may be lower too.

Electrolytes like sodium, potassium, and magnesium help regulate fluid balance, support nerve signals, and keep muscles functioning normally. They also play a role in energy production, which is why low levels can show up as fatigue or brain fog.

We're not trying to overcomplicate hydration. This is just a reminder that during weight loss, drinking water alone isn't always the full picture.

Thinking about hydration as water + minerals can make a noticeable difference in how you feel day to day.

At Redmond, we sell a tasty sugar-free electrolyte mix called Re-Lyte that we think is pretty great. But if a hydration mix isn't for you, you can also benefit from adding a shake of salt and a squeeze of lemon to your morning water bottle. Give it a try.
