Though a bane for dieters, a slower metabolism may actually be a good thing.

The rest coming out over the next few months are:

Were the participants eating the standard American diet? If so reduced oxidative stress may just be because of reduced junk food intake. Would love to see a study like this done on wfpb eaters.

High volume nutrient foods for the win!

Some of us ladies have been on a "diet" almost our entire lives in order to stay slim. Suppose that will extend our lives as you don't see very obese people after middle age.

Thank you so much for making this video. I have heard about this before, bur have not done much research on it before. Thank you!

BMI vs. mortality data shows that a BMI below a certain point increases your mortality risk. How does that square with the calorie restriction evidence? Is the BMI data confounded by people who are underweight due to illness?

I wish I could do this. I know its ridiculous how much I eat. I only eat whole food plant based but can still manage to keep an extra 20-25 lbs of unnecessary weight on me. It might be all the dates with nut butters smeared on them or just the fact that I always have a meal or two a day, in which I get overly full. I guess it food addiction as I had heard that we also produce dopamine from getting a full feeling in the stomach.

My feeling is that you don't need to calorie restrict if you are on a wholefoods plant based diet. Why would you restrict the healthiest food in the world? I am happy to be proven otherwise!

Lets say calorie restriction and emulating dr Gregers lifestyle and example leads to a longer life. The question is if living like that is worth it in order to squeeze out some extra years as a senior? Personally I work out a ton, row 6 times a week and lift weights 4 times a week, a high level amateur. I eat like a horse, 4000+ calories per day. I enjoy being very fit and strong, I enjoy pushing my own limits and the mental and physical battles that comes with it. If I die at say age 75 instead of 85 why does it matter( unlikely 10 years would be shaved off but lets go for an extreme example)? Do people really have this death fear?

Can add I'm almost 40 years old so it's not like I'm some kid without any foresight. I take quality of life over lifespan any day of the week.

Also of course quality of life doesn't have to mean you focus your life around working out and being fit. Could be you are a person who likes to indulge in food. Being a bit overweight doesn't bother you and you would be unhappy if you had to feel like you were on a diet. Why would you change? ( edit: obviously if we are talking about being very overweight, obese, it's a different matter)

There are no guarantees in life. Could be someone drops a piano on your head tomorrow and you take your last breath. The best alternative is to live life the way that makes you the most happy and feel the best.

What about fasting, water fasting, and intermittent fasting??

[TheEnigmaticDeenTruth]

So basically, don't do any work. Calories are needed for work. Gotcha!

Laboratory animals, starve them every third day, they live twice as long.
