    Lots of people criticize low calorie diets in the vegan community. It's often attributed as to why so many people go back to eating meat.

    'You didn't eat enough calories tho'

    Likely a lot of truth to it. But, for me eating much less calories stopped my life long acne, made me lose weight and I kept it off when I gradually ate more and more. Flattened my stomach and generally felt so much better. Much less nausea and woke up feeling energised. My only concern is getting all my RDA of vitamins..

    fasting is a great way to restrict your calorie,but fasting all the time is unhealthy. The 5-2 day is great,fast for 5 days ( omad,not water fast ) and then 2 days eat normal.

    It takes some of the constant work off of the digestive system and that energy can be more readily available to assist other organs in the body. That’s why fasting sometimes can heal ailments.

    It’s easy to CR 25% of your daily calories FOR ME.. Eat a large salad bowl with fruit before eating your main entree and the fiber will slow down your overeating. Fast on Tuesday/Thursday and vegan cheat on ONE day of the week . Make sure you eat your beans especially Lentils and Chickpeas for lunch or dinner. So easy and super cheap.
    Another trick (for me)is eating SLOWLY and enjoying every spoon or forkful and let your stomach tell you when you’re done.

    Intermittent fasting works – don't eat after dinner and have a late breakfast. 16 / 8 works great.
    It reduces calories by stopping mindless snacking in the evening.

    I am SO looking forward to Dr. Greger's " How not to Diet" I've been a vegan for three years and I have to admit, the last 10 pounds has been really really difficult for me to shed. Hopefully I get help through his new coming out book. But I also have to admit, I really don't know how to healthfully do this: I am a whole food plant based puritan….still I have those extra 10 pounds. I have recently added a lot of exercise – and I have great hopes that this will help me.

    You just need to slowly decrease the amount of cal… eating one bite less every single day….the result will come faster then you think…
    Or just try less sugar (maybe 1/6 of a teaspoon) in your coffee every day…
    Huge results after 3 months

    This might be slightly off topic, but I have MS and have found that eating small meals and restricting actually make my feel so much better during the day. I end up being less symptomatic and more energenic. Maybe this had something to do with how the body reacts to calorie restriction.

    The trouble with calorie restriction is that you tend to feel a lot more lethargic. So you may live longer but you won't feel as good. Best not to calorie restrict and do exercise, that way you'll have energy and feel good. Although you may die sooner 🤷‍♂️

And each time I hear that calorie restriction is beneficial for longevity, I get jealous of all the other girls. Meanwhile, they are jealous of me because I'm a freak of nature who can eat anything, anytime, and a lot.

    I have been reading and studying caloric restriction for maximizing my functional longevity for many years, first learning of the concept in a Scientific American article. I do eat much less than I used to when younger, but I do not count calories to reach certain percentages less than a standard caloric load. I enjoy eating, as most humans do, but I do moderate what I eat so that I maintain a healthy bodyfat level and BMI levels. It has become an ingrained lifestyle for me at this point of my life, so I would imagine that I am experiencing some of those positive health and longevity effects that SA magazine mentioned, such as the free radical reduction. Being fully herbivorous for nearly twenty years now has definitely made it easier to maintain a reduction in daily caloric load when compared to my earlier years as a highly carnivorous eater. Thanks for the talk doc!

    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.

    Here's my thing: I eat when I'm hungry. Not when I want to eat, not when my stomach is empty, but when I'm hungry. It goes like this: I eat a bunch of calories in the morning, the majority of my day's worth. Then I go to work. I don't stop working (or running errands or what have you) until I feel this driving force in my belly that interrupts my focus and says (via a feeling) something like 'Ooh, hey there man, it's time to eat. Whatever this is, isn't as important as food anymore.' This feeling will naturally go away and fade to comfortability if I allow it, and I can take my fast pretty deeply depending on how excellent my health is at the time or how far I would like to take it. For the sake of normal circumstances, when I feel that compelling sort of gnawing ache in the stomach that drives me to decide to eat, I go ahead and prepare more food. I try not to snack or add calories in between meals in order to cleanse the system and keep it fresh (try it). When I feel tiny hunger urges that aren't very compelling, I acknowledge them and move on. My body will interrupt me if I'm truly hungry for a meal. This is based on synthesis of all information I've come across thusfar, much of it in alignment with yoga/ayurveda.

    But how many of the benefits of caloric restriction are just due to the benefits of eating less junk? If most of what people eat is bad for them, then it seems that eating less is a good thing. But if you eat nothing but healthy food, would it really be beneficial to restrict calories as opposed to maximizing nutrient intake?

    Woooooooo!!!

    Soooooo today was the day people. Today was the day!!

    6 months I been on keto. Drank wine and had a few cheat days but not many.

    I have lost more than 50lbs. 10 inches off my waist. 2 shirt sizes. Went from 38% to 19% bodyfat and dropping. It's been life changing.

    But everyone talks smack and says wait till you get your bloodwork after eating bacon and eggs for 6 months. I ate other things but that is usually the insult thrown at me by the ignorant.

    Anyway…….

    Doctor called me today. Had a complete panel done.

    My LDL, cholesterol, HDL, triglycerides, blood pressure, organ function, and vitamin and mineral levels were all excellent not even normal. Excellent.

    She said I could add a little more folic acid to my diet was her only comment. Rest was excellent.

    Loosing 50lbs is 1 thing but the proof for me was going to be what my bloodwork was like 6 months later after eating a high fat high cholesterol diet.

    Ans, excellent. Actually better levels now than when I was a vegan and I am 50lbs lighter as a bonus.

    Now I have the concrete data to show my insides are as healthy as my outside 6 months into keto.

    Life changing back by data.

    ⭐️ I started eating a good salad before I ordered any fast food or ate processed food. Slowly, I reduced the size of those meals and became hungrier for veggies and fruit over the course of 4 weeks. Now I'm actually cooking 2 to 3 times per day instead of 0 or 1 and I'm craving the veggies! Soda is tough, but I'm reducing it the best I can. Sugar in my coffee is next. Gotta find a nice flavored drink I like (I'm a drink lover) that is wfpb like most of what I eat now 🙂 All I know is over the course of this past month I've become happier, more energetic, I have less inflammation, my focus and memory are better, and I can breathe better. I don't even want much of the processed stuff now but even when I do I can have a little. But, binge eating is something I gotta watch out for so I do try to keep that stuff out of the house and just binge on my huge salads LOL!
