Whoa. That’s gonna be a big changup for you to go from about 200 - 300 mg caffeine per day to zero.
Just curious as to why you are choosing a no-caffeine approach during your Huel-only diet. And it’s not a judgement thing at all. I myself do only 10 mg of caffeine per day most days from my decaf tea or the chocolate powder in Huel. In essence, I don’t really consume caffeine. But I am very sensitive and was also diagnosed with Tourettes as a child. So, avoiding caffeine is beneficial to me. I get jittery, paranoid, my ticks come back, and it’s counter-productive if I have too much.
However, several studies show that modest amounts of caffeine are not only safe but also beneficial to most people. And there may be other health benefits to having a cup of coffee per day. I think consuming coffee may even be associated with a lower incidence of Alzheimer’s later in life.
I can almost see caffeine abstinence as part of an ascetic approach to a fasting or Huel-only lifestyle. To limit and deprive the body of non-essential nutrients. Asceticism as a word is usually seen as something negative. A person denies himself of worldly pleasures. But asceticism can also be seen as a form of mental and physical training. By not indulging in these extra things (sugary foods, coffee, deserts, elaborately cooked meals, caffeine) your brain is free to focus on more spiritual or person things. Fasting in itself is a form of asceticism because you deny yourself food for a period of time in order to focus on spiritual issues. You understand that you do need food to live, but you also choose not to eat for a particular time. You suffer minor discomfort, but this helps keep you grounded. You learn that you don’t have to indulge every time you see food. You become more resilient mentally and physically. Life is not always gonna give you abundance, so you better prepare youself for life by intentionally denying yourself basic pleasures for a while. Food is there. But you can choose not to eat it for a while and you’ll still be fine. That hamburger is just a 5 minute drive away in the drive-through, but you can choose to consume Huel instead. It may not taste as good as a burger, but you get more benefit from the Huel, both physically and mentally.
I feel that my IF and Huel have given me more benefits that just “losing weight”. I have seen other benefits in my life. I am no spiritual guru. But I get benefits far beyond just being skinnier. In some ways I now see that my cravings for certain foods were child-like. Habitual. And when I first started using Huel and practicing IF, my brain would actually protest and throw fits. My “inner toddler” was challenging my decision to not eat these things. It has opened my eyes to just how much I followed my primitive and habitual nature when it came to food.
(I am rambling now.)
