According to Obesity Research, there are plenty of benefits of intermittent fasting; but like any weight-loss strategy out there, not every plan is meant for everyone. Each individual is different and reacts differently to each diet, supplement or workout routine. Intermittent fasting is no different. Obviously, if you are already underweight or suffer from an eating disorder, you should avoid this strategy altogether.
While macros will differ a little from person to person, the general rule of thumb for keto is to keep carbohydrates under 5% of your daily caloric intake. As long as you avoid the foods mentioned above, you should be fine. Google “TDEE calculator” if you need some additional guidance on how many calories to eat. I’ve had success following this way of eating as it allows me to eat foods that taste great. There are tons of resources online as well if you need additional guidance. A quick google search should turn up a ton of resources. Hope this helps!
