The longevity diet resembles a modified vegan diet in which certain seafood and small amounts of meat and dairy are allowed. It is as much a lifestyle as an eating plan and can be followed for an indefinite amount of time. The guidelines include following a five-day fasting-mimicking diet periodically throughout the year.
The Fasting Mimicking concept is there because this method was exclusively tested on Cancer patients who are also going through Chemo therapy. Having nutrients for these patients is important [1]
Is pure Water Fasting superior? Yes. I have done 1 week water fasts, back to back for 4 weeks and lost ~30 lbs.
However, I think fasting mimicking may help adherence for some people.
I did a DEXA scan at the end only so I don’t know the before accurately. I have some measurements from my Scale on muscle mass which shows a drop of about 2 kgs. Overall I lost about 30-35 lbs of weight. The measurements from the scale should be taken with a grain of salt though because they are based on impedance and formulas that are related to BMI
Fast-mimicking are diets where you eat but gets the same results as if fasting. Fake fasting gimmicks is the real name for this "diets" because you can't fake fasting with food.
