5:2 is where you eat normally 5 days a week and the other 2 you restrict your calories, women 500 and men 600…my mum in law did that one years ago and not only did she lose weight, it lowered her cholesterol too 😃
16:8 is different in that you don’t restrict your calories you just eat in an 8 hr window, for example I’m not a breakfast person so I would start at 1pm and end at 9pm…here’s the science bit…the 16 hours that you are not eating is where the magic happens, your body as you probably know tends to hang onto fat when it thinks there is a famine (you not eating in this instance) but only for 12 hours, after 12 hours your body will have been forced into ketosis (it will burn fat for fuel instead of glucose) so in the 16 hour non eating period (this includes no milk or even sweeteners in hot drinks) your body would fat burn for 4 hours, this includes visceral fat….I have actually done both of these types of intermittent fasting together, a double whammy to the fat you might say 👍🏻😊 hope that helps Kirmmy ☺️
