I’ve been intermittent fasting for a while and here’s what I learned.
Everyone is talking about the benefits but I’m here to talk about the negatives.
IF is very good for calorie restriction, but it’s very bad for micro and macronutrient levels. If you only eat once or twice a day, how do you know you are getting the right nutrients to survive long term? You don’t. You have to track. I don’t think this is negotiable. Yes you guys are losing weight, but a lot of you are also nutrient deficient. Remember skinny people have health problems at an old age too. That’s nutrition.
I’m glad everyone is benefiting from IF and is repairing their relationship with food, but think about yourself long term. This whole “eat whatever I want and still lose weight” is the danger I need to warn people about. It is true, but you’re gonna regret that at 50 when you realize you haven’t been giving yourself the proper nutrition to survive long term.
You don’t have to be anal and track down to the last number, but you should be aware of what your body needs based on your metabolic rate.
If you’re doing IF or OMAD and you are not tracking your macros, you are doing yourself a disservice. And you might not believe it now, but you will after 10 years of malnutrition.
So do IF. But make sure you are still getting appropriate levels of protein carbs and fats. And all the micronutrients in between.
Answer
I think I understand your intent here, but:
-
You don’t know what your macros are unless you track anyway, regardless of whether or not you’re doing IF.
-
A person DOES NOT lose weight on IF if consuming more than is burned… which also requires tracking. One meal can easily exceed BMR/activity burn if a person isn’t mindful.
-
People can be overfed and undernourished. If someone is not consciously eating food that contains vitamins and minerals needed for optimal cellular function and/or supplementing, it doesn’t matter how much or little is consumed.
Answer
I mean, if you eat like crap, yeah, you’ll have deficiencies and health issues. But this has nothing to do with IF. Eat like crap once a day or eat like crap three times a day plus 2 snacks, same results.
>eat whatever I want and still lose weight
That is so not what IF is about.
I’d say a bigger danger is people undereating (which does relate somewhat to your point, to some degree).
