What happens in my body during the Revive in Five Fast (RFF)?

Day 1: Transitioning into a Fasting State. Your body burns through its glycogen stores and prepares to enter ketosis.

Day 2: Fat Burning & Ketogenesis. Fat-Burning begins in earnest, and your body begins converting fat into fuel and producing ketones.

Day 3: Autophagy Cellular Clean-Up State.Cellular clean-up (autophagy) begins. Fat- Burning and ketone production/utilization continues and increases.

Day 4: Cellular Rejuvenation. Cellular clean-up and renewal continues, as does fat-burning.

Day 5: Renewal & Change. Fat burning and cellular renewal continue today and even beyond Day 5. Congratulations on successfully completing your fast and rejuvenating your entire body!

TIPS FOR A SUCCESSFUL FAST

Drink Plenty of Water: Dehydration will hinder your health and weight-loss efforts, so aim to drink at least 85-100 oz of water daily.

Bored with Water?: Try drinking herbal (decaf) tea, fruit-infused water, or carbonated water (with no sugar added) the bubbles may actually help you feel fuller.

Coffee Is Still On The Menu: You are welcome to enjoy your coffee as long as you keep it to 8-12 fl oz per day. Just don’t use any creamers or sweeteners—they will derail your fast!

Be Active: Light workouts like stretching and walking are recommended daily. Not only is low-intensity movement great for circulation and burning body fat, but activity can help keep your mind off of food cravings.

Share Your Journey: Let people know about your fast so they can support you and hold you accountable. You may even inspire them to take steps toward improving their own health!

Meditate: This will keep you calm and centered while helping with mental focus and clarity. Meditation can be as simple as taking a few moments to sit in nature and breathe deeply.

Stay Productive: Use this time to focus on work or complete projects! Keeping your mind and body active means you’ll be less likely to focus on your hunger.

Prioritize Sleep: Good sleep is key for good health. Make sure you get at least 7–9 hours of sleep a night, even if that means heading to bed earlier than usual.

Be Your Own Coach: Write down the reasons you decided to take control of your health in the first place and read them daily. Envision how accomplished you will feel on Day 5!

Fast With Friends: If you’d rather not go it alone, enroll a group of friends to take on the five day challenge with you! You’ll keep each other accountable while reaching your health goals together.

Take Your Meals With You: Just because you’re “fasting” doesn’t mean you need to stay home or avoid social engagements! Take your snacks outside for a picnic, or join friends or family for dinner.

Help Out Where You Can: Take your mind off yourself and your hunger and make a positive impact by volunteering in your community.

RFF Diet FAQs

What is the Revive in Five Fast (RFF) and how does it work?

The Revive in Five Fast (RFF) is a five day plant-based, restricted-calorie meal program that allows you to experience all the healthy benefits of fasting–including weight loss, belly fat loss, cellular rejuvenation, improved energy, decreased blood pressure, and better sleep–while still getting to eat. 

We recommend doing a series of at least three RFF cycles spaced one month apart in order to enjoy maximum health benefits.

Is fasting healthy and safe?

For most people, yes. However, if you have a health condition or any concerns about fasting, you should speak to your healthcare provider before starting the RFF fast.

Since the RFF limits calorie intake, common side effects may include fatigue, headaches, dizziness, musculoskeletal pain, nausea, difficulty and concentrating. 

Significant changes in diet can also cause changes in your gut such as cramping, gas, bloating, constipation or diarrhea. Symptoms in most people will be mild and temporary.

RFF is designed to prevent many of these typical fasting side effects by providing specific macro and micronutrients. However, because it is still a low-calorie program, we encourage you to discuss with your healthcare provider whether the practice of fasting or the use of RFF is right for you. To minimize any risks associated with fasting, please follow these recommendations during the 5-day program: 

  • Avoid any strenuous exercising or activities that may burn a high level of calories.
  • Avoid extreme temperature environments like hot tubs and saunas, or driving long distances under strong sun or heat.
  • Since this is a food-based program, please stop using the product if you experience any symptom of an allergic reaction such as a rash, change in voice, swelling, or fever.
  • If you feel light-headed or faint, you should eat something or consume your electrolyte drink. If your symptoms do not subside, please contact your physician, or if you feel this is a life-threatening emergency, call 911.

What is Intermittent Fasting (IF)?

Intermittent fasting can be defined as fasting for fewer than two days. Time-restricted eating, the 5:2 diet, and alternate day fasting are all included under the umbrella term of IF.

While there are a variety of fasting methods within the category of IF, they are all based on eating patterns that alternate between intervals of eating and fasting.

WHAT IS TIME RESTRICTED EATING (TRE)?

Time Restricted Eating (TRE)  limits meals to a certain window of time or “eating period” per day. By shortening the time spent eating each day, you are likely to eat less and therefore consume fewer calories.

Do I need to do Time Restricted Eating (TME) while on Revive in Five?

No. Between cycles of RFF, you can consume your food between your fasting windows in adherence to TRE if you want to, but you don’t need to do TRE when doing RFF, as you are already getting the benefits of TRE (and more!) when you do RFF.

What is the difference between the definitions of common fasting, physiologic fasting, and molecular (cellular) fasting?

  • Common Definition: Abstinence from all or some kinds of food and drink.
  • Physiologic Definition: The switch from burning glucose for energy to burning fatty acids and ketones as a main source of fuel.
  • Molecular (Cellular) Definition: The state in which nutrient sensing pathways are inactive or down-regulated.

The Revive in Five Fast causes you to enter both a physiologic and molecular fasting state. It doesn’t trigger nutrient sensing pathways, meeting the molecular definition of fasting. It also triggers the switch from burning glucose for energy to burning fatty acids and ketones as the main source of fuel, so it meets the physiologic definition of fasting.

The RFF also stimulates stress resistance. An important part of stress resistance is autophagy, or cellular clean-up, where the cell targets cellular debris such as misfolded proteins and worn-out cellular components for recycling, leaving the cell rejuvenated.

Should I restrict calories or prepare my body before beginning the RFF?

You don’t need to make any long-term, major lifestyle changes before starting the program. However, to ease your transition into fasting, we recommend you be mindful of your portions, eat nutritious foods, increase your intake of plant-based foods and of vegetables, avoid processed and sugary foods, and cut down on your caffeine as much as possible in the week prior to beginning the RFF.

What if I get really hungry during the RFF?

Keep in mind that there’s a difference between cravings and hunger. Cravings are normal while doing RFF and generally pass within a short period of time. To address cravings, keep yourself distracted, and drink sparkling water (unflavored, unsweetened) and/or non-caffeinated, herbal teas. Like cravings, hunger also generally passes quickly, and we strongly recommend against eating “extra” food, which could take your body out of the fasted state. If your hunger is intolerable, as a last resort before breaking your fast, you may have a slice or two of apple, OR 1 stalk of celery, OR 1 small Persian (“baby”) cucumber of 5-6 inches in length per day. If you add more than one of these additions, it will likely stop your body from being in a fasted state.

Can I eat the day’s food at different times?

According to the trial design, the order and timing in which you eat each day’s items does not impact the outcome. You can consume the entire day’s contents in a single sitting if you’d like, though we do not recommend doing so, as you’ll have many hours of no nutritional intake and you may get very hungry or experience increased side effects, like headache and fatigue.

Can I eat/add anything that is not on the program?

You may add:

  • Up to 1 tablespoon of dried herbs or spices per day to your soups or other foods in the diet to enhance the flavor (preferably unprocessed)
  • Up to 1 teaspoon of sea salt (as long as there are no health contraindications)
  • Up to 2 slices of lemon per day (squeezed, not eaten), whether you use it in your soups, herbal teas, or water
  • Up to 2 pieces of sugar-free gum per day 
  • Unlimited herbal teas (unsweetened and caffeine free)
  • All types of sparkling water (no sweeteners of any kind)
  • Caffeine up to 140mg per day:
    • 1 cup (8fl oz) of coffee (no cream or sweetener)
    • OR 2 cups (16fl oz) of black or green tea (traditionally steeped), no matcha
    • OR 6 cups (48fl oz) of decaf coffee (no cream or sweetener)

What is the Transition Day Diet recommended on Day 6?

We advise you to keep your meals light and small, and GO SLOW. Start with liquid foods, like soups and fruit juices, followed by things like rice, pasta and small portions of meat, fish and/or beans as you can tolerate them. 

Can I exercise during or after the RFF?

While exercise can help use up available blood glucose and move a person into a ketogenic, fasting state, vigorous exercise can also stress the body, so we do not recommend intense exercise during the RFF. While fasting, keep your activity light and do things like walking, yoga, and stretching.

Listen to your body as you ease back into exercise after fasting. If it feels like it’s too much, it probably is. Don’t push yourself too hard and keep the intensity at a manageable level. Remember, your body needs to recover after fasting, so it may take a few days for you to get back to the level you were at before the fast.
