One scoop of Athletic Greens is all it takes to break your fast.
Not maybe. Not sometimes. Always.
You can argue with me about calorie wiggle room or “modified fasting,” but the truth doesn’t bend just because you want a supplement to fit into your window.
Fasting has rules. Break them, and you’re not fasting anymore.
Why AG1 Breaks a Fast
Athletic Greens (AG1) is a 50-calorie hit in a scoop.
That’s 6 grams of carbs, 2 grams of protein, plus vitamins, minerals, probiotics, and other additives.
Does that sound like “nothing”? No.
That’s a meal in disguise, small, yes, but enough to wake up your metabolism and shut down the very state you’re chasing during a fast.
Calories trigger insulin. Nutrients end autophagy. Protein interrupts fat-burning.
You don’t need a PhD to get this: if you swallow 50 calories mid-fast, you’ve broken it.
The Real Question: What Are You Fasting For?
Here’s where people twist themselves into knots: “But, it’s only 50 calories… will it really matter?”
It depends on your goal.
- If you’re fasting purely for weight loss:
50 calories won’t make you fat. You can drink it, stay under your daily calories, and the scale will still move.
But let’s not kid ourselves, that isn’t clean fasting. That’s dieting with training wheels, and it doesn’t get you where you want. - If you’re fasting for deeper benefits:
Autophagy, insulin sensitivity, gut rest, ketosis, AG1 destroys them.
It takes just one scoop to turn off those switches.
Your cells sense nutrients, and the clean-up process halts.
Insulin rises, fat-burning slows, and the “reset” you brag about on Instagram? Gone.
So ask yourself: do you want half-baked results, or do you want the full payoff of fasting discipline?
When to Take Athletic Greens Instead
AG1 isn’t trash.
It’s loaded with vitamins, minerals, probiotics, enzymes, and fiber.
It supports energy, digestion, and satiety. But it belongs in your eating window, not your fast.
Here’s how you actually make it work for you:
- Start of eating window: take AG1 before your first meal. It gives you a nutrient base, calms hunger, and prevents binging.
- During meals: mix it into breakfast or your post-workout food. It amplifies satiety and helps with gut health.
- Never during your fast: don’t be the guy who sabotages 16 hours of discipline for a scoop of greens water.
Supplements should support you after the job is done, not while you’re in the middle of it.
The Side Effects of Sneaking AG1 Into Your Fast
If you down AG1 during your fast, here’s what actually happens:
- Insulin spikes – those 6 grams of carbs and 2 grams of protein push blood sugar and insulin up. That’s enough to slam the brakes on fat-burning.
- Ketosis disruption – fasting pushes your body into fat-burning. Carbs in AG1 nudge you back out. You just traded progress for flavored water.
- Autophagy interruption – fasting tells your body to clean up damaged cells. AG1 tells your body, “We’ve got food, stop the cleanup.”
The Hard Truth on Supplements and Fasting
Supplements don’t get a free pass.
Coffee without cream? Fine. Green tea? Fine. Water? Perfect.
Athletic Greens? Not during fasting.
If you need a scoop of AG1 to “get through” your fasting hours, you don’t have a fasting problem; you have a discipline problem, or maybe your fasting window is too huge, and you are not adapted enough. Back down for some time.
Every time you cheat with Athletic Greens powder, you weaken that muscle and rob yourself of results.
Final Takeaway: Keep It Clean or Don’t Bother
Yes, Athletic Greens breaks your fast.
If fasting results matter to you, save AG1 for your eating window.
Use it to boost energy, feed your gut, and make meals more nutrient-dense.
But don’t lie to yourself, if you’re chasing fat-burning, autophagy, or true metabolic reset, you can’t sip your way around basic biology.
