Hi Hithere! This web side is for what is known as the 5:2 diet, fasting two days a week and eating normally 5 days a week. On fasting days, women eat 500 calories inside an 8 hour window and men eat 800 calories. Not everyone does it that way. Some are doing 16:8, which is fasting 16 hours and eating within an 8 hour window. I fast on Mondays, Wednesdays, and Fridays, where I drink only water. On the other days, I eat normally three meals a day but I count calories so I stay within my TDEE (that’s my personal daily calorie amount based on height and weight). Some people do B2B fasting days (they fast two days in a row). I don’t know if what you are doing is bad. There are people who fast up to 5 days safely, and some do even longer. I personally wouldn’t do that. I can only imagine people being weak and unable to function properly that way. I guess each person has to find his own way. Check out resources above. There is info there. Good luck!

Hithere, you are essentially following an “eating window”, which is quite different to 5:2 One just limits the period of time each day that you eat, the other limits the calories that you eat 2 days per week.
Eating only eggs, bacon and salad doesn’t sound like it will provide your body with all the nutrients it needs. As you have an illness that has to be taken into account, I think you be better talking to your doctor and perhaps a dietitian to work out a food plan that helps your disease but is also good for your health generally.
