About the Longevity Fasting Diet

About the Longevity Fasting Diet

Sip Kitchen’s five-day Longevity Fasting Diet (LFD) is a calorie-restricted protocol based on the research from the Fasting Mimicking Diet (FMD™). The FMD™ was developed by Dr Valter Longo and his team at the Longevity Institute after decades of ground-breaking research on longevity. Fasting-mimicking diets such as the LFD contain macro-nutrients in precise quantities & combinations, with a low carbohydrate and a very low protein and sugar content, that aids adherence to the fast, whilst keeping you in the desired fasted 'catabolic', rest and repair state.

The purpose of severely restricting protein and limiting carbohydrates and sugars is to switch your body into rejuvenation versus growth mode. Our natural repair mechanisms become damaged over time, however, this protocol helps up-regulate these mechanisms to improve our ‘health span’.

The five-day FMD™ was developed to promote healthy longevity through:

  • Promoting longevity and cell-based renewal
  • Improving biomarkers such as insulin sensitivity, triglyceride levels, and cholesterol, which are common indicators of metabolic syndromes such as type II diabetes and heart disease
  • Switching all cells to protected anti-aging mode
  • Encouraging cellular autophagy (the process by which your cells consume their damaged parts, using them as energy for healthy cells)
  • Cell apoptosis and subsequent regeneration (killing off damaged cells and replacing them with newly regenerated cells from activated stem cells)
  • Igniting fat burning through nutritional ketosis, in particular visceral/ abdominal fat
  • Gaining control over your nutrition & kickstarting healthier eating habits
  • Improving energy, mental clarity & focus


Sip Kitchen’s LFD Meal Pack

Your organic, whole food meal packs contain all of the food you will be eating over your five-day mimicked fast. Your meal packs contain a combination of soups, warm vegetable dishes, breakfast items, and snacks, made from fresh, organic, seasonal, and plant-based ingredients. We have calculated the calories, fats, proteins, and micronutrient profiles of each meal to ensure that they are consistent with the published FMD™ recommendations.

We have made the meal plan as tasty and satisfying as possible whilst operating within tight parameters to ensure all meals are:

  • Consistent with the published clinically defined nutrient and calorie guidelines
  • Made with organic ingredients (where available)
  • Plant based (vegan)
  • Paleo
  • Dairy-free
  • Gluten-free
  • Grain-free
  • Sugar-free

Summary of Sip Kitchen’s LFD Nutrition Parameters


The LFD contains very low quantities of protein from plant-based sources only. There is no room in the macros for animal proteins.


The LFD contains complex carbohydrates from plant sources with less than 13g of sugars on any of the fasting days.


The LFD contains fats primarily from “healthy” oils such as coconut oil and olive oil, and from nuts such as almonds and macadamias.


Day One

Calories are limited to 1,100 in total comprised of:

Fat: No more than 56% of the day’s total calories

Protein: 10% of the days total calories

Carbohydrates: No more than 34% of the day’s total calories

Sugars: No more than 10% of the day’s total calories


Days Two-Five

Calories are limited to 800cal comprised from:

Fat: No more than 50% of the day’s total calories

Protein: 9-12% of the days total calories

Carbohydrates: No more than 40% of the day’s total calories

Sugars: No more than 11% of the day’s total calories


Day Six

Day six of the LFD is your first day of refeeding. This is a very important part of the LFD as it initiates the regeneration process that you’ve worked so hard to achieve during your five-day fast.

You should consume approximately 1,200-1,400 calories on day six. We recommend eating a diet that is whole-food based i.e. plenty of fresh vegetables, quality low-inflammatory fats and protein; wholegrain and root vegetables for slow release sources of carbohydrate. If you would like help with your refeed meals, we created a day-six refeed meal plan specifically for the LFD which you can purchase here.
