Thanks, Nancy, for your appreciation and kind words. As far as IF is concerned, it certainly helps with weight loss. I have had communications with another writer here on Medium, Charisse Tyson (https://charissetyson.medium.com/) who also lost quite a considerable amount of weight through IF. If you choose to communicate with her, feel free to mention my name.

Now, the evidence for the effects of IF on various aspects of health is not as conclusive as you’d wish for. But we know two things for sure: first, it doesn’t do any harm, and, second, it might simply be that we don’t have the right biomarker benchmarks yet to quantify its beneficial effects. The minimum consensus is that, and I quote from a recent review, “IF may improve cardiometabolic health by lowering blood pressure, insulin resistance, and oxidative stress, but their ability to improve plasma lipids and markers of inflammation remains uncertain”. In science terms “uncertain” simply means that some studies showed some effects, and others didn’t.

My point is always: to look at the individuals in the studies. There is always a large inter-individual variability, which says one thing: everyone reacts differently to the same intervention.

My personal experience: with IF I sleep better, control my weight better, feel better, and my daily measurements of the rate of vascular aging confirm all this. So, if it helps you, continue with it.

After all, there is an evolutionary argument in favor of IF: our ancestors were never exposed to the round-the-clock feeding paradigm that prevails in today’s societies. So, cycling between fed and fasted states is probably closer to the conditions that stamped our genes than this obsession with eating breakfast, lunch and dinner, and anytime in between.
