What to Drink During Fasting to Boost Metabolism: Real Drinks That Actually Work

Ever notice how some people breeze through fasting while others crash halfway through? The secret often comes down to what they drink. The right beverages can wake up your metabolism, keep hunger calm, and make fasting feel a whole lot easier. Let’s look at how smart drink choices can help you stay energized and in control when you’re fasting.

Why What You Drink Actually Matters

When you’re fasting, hydration is only part of the picture. What you sip changes how your body burns fat, handles insulin, and stays focused. The goal is to pick drinks that support your metabolism without breaking your fast.

That’s why I like two powerful helpers: BALANCE and Unimate. BALANCE helps your body handle carbs and cholesterol when you eat again, while Unimate keeps you alert and satisfied during the fasting window. Think of them as your start-and-finish duo for smoother, more successful fasting.

Top Drinks to Boost Metabolism During Fasting

Here are some of the best drinks to keep your metabolism firing and your energy steady.

Apple Cider Vinegar with Lemon Water

Start simple. A tablespoon of apple cider vinegar in a glass of water with a squeeze of lemon does wonders for digestion and insulin sensitivity. It’s a little sour kick that helps your body manage carbs better. Skip it if your stomach is sensitive, though.

Black Coffee

If fasting had a best friend, it would be black coffee. Organic, unsweetened, and calorie-free, it helps burn fat and keeps your mind sharp. Just keep it plain. No sugar, no cream, no “just a splash.”

Green Tea

Green tea is gentle but powerful. It’s full of antioxidants and a mild hit of caffeine that boosts metabolism. Plus, it can take the edge off hunger. I like it iced mid-morning when coffee feels too strong.

Herbal Tea

Caffeine-free options like chamomile, peppermint, or ginger tea soothe your system. They’re great for curbing cravings or winding down before bed. Cinnamon tea’s another solid choice—it smells like dessert without the sugar.

Carbonated Water

If you miss the ritual of drinking something fizzy, carbonated water hits the spot. It’s refreshing, fills you up a bit, and keeps your mouth busy when you’re tempted to snack. Just make sure it’s plain, not flavored.

Unsweetened Electrolyte Water

During longer fasts, electrolytes are your lifeline. A pinch of sea salt or a bit of magnesium powder in your water keeps muscles from cramping. Skip the sugary sports drinks—those are basically dessert in disguise.

BALANCE: Your Pre-Meal Reset

Breaking your fast right matters as much as what you do during it. That’s where BALANCE shines. It’s a pre-meal drink that helps your body handle carbs, cholesterol, and appetite. Most of us don’t get enough fiber, especially with all the processed food around. BALANCE fills that gap with soluble fibers and plant nutrients that slow digestion just enough to keep blood sugar steady.

Here’s what it does:

  • Slows down how your body absorbs carbs and dietary cholesterol

  • Supports healthy glucose and cholesterol levels

  • Calms hunger between meals

  • Keeps digestion smooth

  • Works beautifully with intermittent fasting or time-based eating

I’ve seen it make a difference for people who usually crash after eating. One glass before a meal helps them stay full and balanced for hours. It’s lightly sweet, plant-based, and a smart way to end your fasting window on the right note.

Unimate: Your Morning Power Boost

Unimate

If you’ve ever tried fasting and felt drained or distracted, Unimate changes that game. It’s a concentrated yerba mate drink that gives you clean, calm energy to get through your morning fast. No sugar. No jittery buzz. Just steady focus.

Here’s the cool part—it supports GLP-1, a hormone that helps control appetite naturally. That means you can go longer between meals without feeling like you’re starving. I’ve had mornings where Unimate kept me going until 1 p.m. without even thinking about food.

What it helps with:

  • Keeps you alert and focused

  • Curbs appetite without stimulants

  • Lifts your mood and energy

  • Prevents sugar crashes

  • Makes it easier to stick with your fasting routine

If belly fat is your battle, Unimate helps there too. The GLP-1 support keeps cravings down, which means fewer impulse snacks and steadier progress.

Tips for Smarter Fasting

There’s no perfect formula, but a few small habits make fasting easier:

  • Read labels. Avoid hidden sugars or fake sweeteners like maltodextrin.

  • Hydrate well. Aim for 8 to 10 cups of water daily.

  • Add electrolytes. A pinch of salt goes a long way for muscle and nerve balance.

  • Use your duo wisely. Start your day with Unimate for focus, end your fast with BALANCE for smoother digestion.

  • Listen to your body. If you feel lightheaded or weak, tweak your schedule or add more fluids.

Pairing Drinks with Your Goals

Not every drink works for everyone. Here’s a quick cheat sheet to guide you:

Drink Main Benefit Watch Out For
Apple Cider Vinegar Helps control blood sugar Can cause acid reflux
Black Coffee Boosts fat burning May irritate stomach
Green Tea Increases metabolism Contains caffeine
BALANCE Stabilizes blood sugar, curbs hunger High-fiber content
Unimate Sustains energy, supports GLP-1 Not ideal if caffeine-sensitive
Electrolyte Water Prevents dehydration Avoid sugary versions

 

The Takeaway

Fasting doesn’t have to feel like punishment. The right drinks make it smoother, more effective, and even enjoyable. Keep things simple—coffee, tea, carbonated water—and add smart functional drinks like Unimate in the morning and BALANCE before your first meal.

These small choices stack up. You’ll feel more in control, more energized, and less distracted by hunger. Fasting is a journey, not a sprint. With the right hydration and a little strategy, you’ll get stronger with every fast.
