A Beginner's Guide and Quick Overview of Cycle 1 of the 17 Day Diet

Cycle 1 is the Accelerate Cycle

Cycle 1 of the 17 Day Diet is also known as the “Accelerate Cycle”.  The primary purpose of Cycle 1 is to experience rapid weight loss, which helps flush sugar and fat storage from your system.

Think of Cycle 1 as the “cleansing” cycle  releasing toxins from your body.

Quick Overview of Cycle 1

During Cycle 1, you will eliminate most carbohydrates with the exception of some low-sugar fruits and you will eliminate sugar all together.

You’ll enjoy generous amounts of lean proteins such as chicken, turkey and some fish and various low-glycemic index vegetables as well as probiotics to help promote a healthy digestive system.

Cycle 1 Recap

Here’s a quick recap of Cycle 1 to get you started:

  • Wake Up Drink:  Within a half hour of waking, drink hot lemon water to get your digestive juices flowing.
  • Green Tea: Drink green tea with most of your meals– Green tea is full of anti-oxidants and helps promote weight loss.
  • Water: Drink at least eight 8-oz glasses of plain water every day.  If you can drink more, the better!
  • Eat generous amounts of lean protein and certain veggies.
  • Consume two servings of probiotics per day.
  • Eat two servings of fresh low-sugar fruit by 2pm (only fruits from the approved list).
  • Friendly Fats: Use 1 to 2 tablespoons of Olive Oil or Flax Seed Oil per day.
  • No sugar is allowed
  • No alcohol is allowed
  • Light exercise for 17 minutes each day
  • Only stay on Cycle 1 for 17 Days — not a day longer!


Cycle 1 is only meant to be used for 17 days and no longer.  If you reach your weight loss goal after Cycle 1, continue onto Cycle 4.

What If I Still Have Weight to Lose After Cycle 1?

If you still have weight to lose by the time you’re finished with Cycle 1, you are encouraged to move along to Cycle 2 and finish through Cycle 3 before returning to a previous Cycle to continue to lose additional weight.

Staying on Cycle 1 for too long may result in a sluggish metabolism as your body will get used to eating the same way or a long period of time.

    • If you want to make a smoothie using high-protein greek yogurt, that would be fine. Otherwise, I don’t believe using protein powder to make a drink or a pre-packaged protein shake is allowed.

    • I think if the ingredients say “green tea” you should be OK. Make sure there is no sugar added or anything artificial. Just plain old green tea with natural flavors such as lemon, mint, etc.

  1. Hi, I’m a vegan and have been using beans, tofu, and protein powder for my proteins. Is that endorsed by the diet or are there other proteins I should be using?

    • Yes, those items are accepted by the 17 Day Diet (protein powder is iffy, but if you’re seeing results, keep using). I think you covered most of the protein sources.

    • I think what makes this drink work is the combination of heat and lemon. You can try room temp water, but if the book calls for hot water, there’s probably a reason for it.

  2. Hi I’m on day 3 of the diet and I was wondering if I could add Truvia to my green tea? I just cannot drink it plain.

    Thank you!

  3. Can you drink the diet citrus Lipton green tea on this diet? I don’t like hot green tea, and this is the only one I found that I can drink.

    • Danielle, this diet was created by Dr. Moreno (MD) and many people have been on this diet, or some variation of it for the last few years. Best to ask your doctor if it’s safe for your circumstances.

    • You can certainly put lemon in your tea, but if you’re looking for the digestive properties that hot lemon and water provide, then best to stick with the original combo. I don’t think the tea & lemon will give you that same benefit.

    • Sally, probably the best advice I could give is to disregard what the name says and go straight to the ingredient list. You’re going to find that just because the name of a product has “strawberry” in it doesn’t necessarily mean there are strawberries in the actual ingredient list. Pretty scary, huh? So head to the ingredient list, and if you see green tea on the list (it should be at least the first or second ingredient), then that’s a good sign. The next thing to look for is sugar. If there’s added sugar, don’t buy it. The last thing to look for is artificial ingredients and artificial sweeteners. If you see these, run for the hills!

      If you can, brew your own green tea. If you like your tea cold, then chill it and add in your own natural sweetener. This way you know exactly what you’re getting because there is so much garbage out there! Good luck and have fun!

  4. Hi.. I am a newbie and am totally lost on how to do the cycles.. Do you do each of them for 17 days.. Please tell me how the cycles are done..

  5. My sister and I have been following the diet, along with my nieces. We have all had much success. The nice thing is that you don’t have to feel like you are starving!
