Anyone combine PSMF w/fasting?

Soo, if you don't know, PSMF (protein sparing modified fasting) is basically keto minus the fat. The idea being that you get all the nutrients you need, but subtract the fat so your body eats your fat for energy. See the subreddit PSMF for more deets. I wondered if anyone combined the two? For instance, I do ADF, alternate day fasting. What if, on my eating days, instead of eating maintenance calories in keto, what if I ate like 700 calories with a maintenance amount of protein, but made my body make up the rest of the calories off my butt fat? Anyone do both at the same time?

Answer

This is exactly what I do. Once the body has become fat-adapted then it makes sense to restrict dietary fat, cause the body will just feed on its reserves. Keeping protein macros consistent to maintain and repair muscle mass at the same time. Sounds like you’ve got a solid plan.

Answer

From everything I’ve read, I don’t think intentionally restricting your calories so much during eating periods is good long term. Definitely a solid idea short term, say like a month. I just do keto and right now I’m still losing weight without calorie counting even when I feel like I overeat. I started throwing in multiple fast days a week a few weeks ago.
