Got summer plans, outfits, even destinations picked out… but still carrying a few pounds you swore you'd drop by now? Don’t stress—we’ve got you. There’s still time to look and feel like your best self.
Before you panic-Google another cleanse, sign up for back-to-back bootcamps, or consider “borrowing” your aunt’s mystery weight loss pen (oz-something), hit pause.
There’s a better, safest and less expensive way to get you closer to the body you dream of.
We’re talking about fasting—a scientifically backed tool that’s helped thousands drop fat, boost energy, and feel in control again. It’s not the only method out there, but for many, it’s one of the most effective (and simplest) to implement—especially when done right.
Let’s break down how it works, what the science says, and how to use it without losing your mind—or your muscle.
What Is Fasting—And When Does It Actually Start?
Fasting isn’t a trend—it’s a metabolic process hardwired into your biology. The idea is simple: you go a set number of hours without consuming calories, giving your body a chance to switch gears and tap into stored fat for fuel.
When does a fast “officially” begin?
According to studies, fasting benefits typically begin around 8 to 12 hours after your last calorie intake. That’s when:
- Insulin levels drop
- Glycogen stores deplete
- Your body shifts from glucose to fat-burning mode (lipolysis)
- Processes like autophagy (cellular repair) begin to activate
One study published in Cell Metabolism found that time-restricted eating improves metabolic health and enhances fat oxidation and insulin sensitivity—even when calories are not reduced.*
But not all fasting windows are the same. That’s why we’ve laid out three evidence-backed routines, depending on your level.
Choose Your Fasting Style
| Level | Fasting Protocol | Eating Window | Max Fasting Weekly Hours | Tips to Make It Easier |
|---|---|---|---|---|
| Beginner | 12:12 | 12 hrs | 84 hrs | Start by aligning your fast with your sleep. Example: stop eating at 8 PM, have breakfast at 8 AM. Most people do this unknowingly—now just make it intentional. |
| Intermediate | 16:8 | 8 hrs | 112 hrs | Delay your first meal. A shot of Burn2o or a cup of black coffee can help blunt appetite in the morning. Bonus: most cravings fade by hour 13. |
| Advanced | 18:6 to 20:4 | 4–6 hrs | 140 hrs max | Keep fasts consistent—your body adapts. Avoid breaking fast with heavy meals; go for protein + fiber first to stabilize blood sugar. |
Pro Tip: A lot of people find fasting easier when they align it with their sleep cycle, it's an effortless hack for success.
What Can You Drink During a Fast?
Fasting doesn’t mean zero everything—just zero calories. And the right drinks can actually make your fasting experience easier and more effective.
Here’s what’s allowed during a clean fast:
- Water (still or sparkling)
- Black coffee
- Unsweetened tea (green, black, herbal)
- Electrolytes (as long as they’re zero-calorie and without sweeteners)
- Certain pre-workouts and thermogenics — if they’re stim-free, sugar-free, and calorie-free
Which brings us to the ultimate tool to supercharge your fast without breaking it…
Burn2o: Your Fasting Ally
Meet your secret hack for turbocharge your fasting: Burn2o—the world’s first and only liquid thermogenic designed for serious fat burn and metabolic support… all while being zero sugar, zero calories, and zero stimulants.
That’s right—it won’t break your fast. But it will make it work harder for you.
Here’s how Burn2o levels up your fasting game:
- Boosts thermogenesis: Thanks to ingredients like MitoBurn® and CaloriBurn®, it supports your body’s ability to burn more calories while in a fasted state.
- Enhances fat-to-energy conversion: L-Carnitine helps transport fat into the mitochondria where it’s used as energy—perfect when glycogen is depleted.
- Supports mental clarity: GBB and other nootropic-like elements support sharper focus and alertness—key during longer fasting windows.
- Zero crashes, zero jitters: Because it’s stim-free, it won’t mess with your hormones or nervous system like caffeine.
Burn2o can be taken anytime, it is super versatile: First thing in the morning, before a fasted cardio session, or as your midday fast-extender, so you don't fall asleep at job—it’s pure fire in a bottle.
What Can You Drink During a Fast?
If you’re still a few pounds away from where you want to be, you don’t need to panic or punish yourself. Instead, give your body a chance to do what it knows.
Fasting is simple. Effective. Free. And when you combine it with tools like Burn2o, it becomes a fat-burning accelerator that feels almost unfair.
This isn’t just about looking leaner in shorts (though we’re not mad about that). It’s about energy, control, and momentum—heading into summer feeling sharp, strong, and in charge.
Your move.
Choose the protocol that works for you, sip smart, and let your body do the rest.
