Yes. The first time I Intermittent fasted was about 30 years ago when I had never heard of IF. I just decided to eat one meal a day, which is now known as OMAD. Neither one existed to me at the time. It was just something I decided to do so I could still eat what i wanted in one meal and lose weight. Lost about 2 pounds per week and 30 overall to get to my goal weight.
Recently, instead of IF, I do occasional 3 day to more days of water only fasting. Two years ago, I did a 30 day water only fast. The reason now is for health. The weight loss is an added benefit. Ironically as we speak I am on day 8 of a planned 30 day or more water fast with a plan to revert back to a whole foods, plant-based way of life. As Joel Fuhrman recommends, a nutritarian diet.
Alan Goldhamer of True North is a great advocate, too
We are set up to fail by the SAD American diet. SOS, salt, oil and sugar.
Now that I am retired, I feel that I can truly focus on that major area without the requirements or interference of a job and stress. Now that my financial matters are set, it is time to tackle this.
I always feel better when I eat better but old habits, as we all know, are hard to break. But we must never give up.
