I'm doing 16:8 because it fits with my lifestyle much more easily than 5:2. I basically stick to eating between 12noon and 8pm. Outside that, I stick to water, tea and coffee. It's easy to skip breakfast, in fact it makes the preschool rush much more manageable only having children to think about! Then I keep busy through the morning, and have lunch at 12noon with the children if they are home from school. Same in the afternoon, dinner at 6:30/7:00 pm, that's it for the evening.
I don't go mad and eat anything during the eating period. ATM we are on holiday, so have to plan a big salad lunch, maybe with quiche or a couple slices of bread and pâté, yogurt and fruit after. I try not to snack in the afternoon, but may inhale a couple of biscuits with a coffee around 3pm! Sensible dinner, usually protein (chicken, fish, pork chop, quiche) plus a couple of salad or veggie dishes (rice salad, green salad, potato salad, couscous and roast veggies, Thai salad etc - I make big bowls of these and we help ourselves). Sometimes a small dessert, not always. A glass of wine with dinner most days.
The benefits over 5:2 for me were not having to plan the fast days, I much prefer having the same routine every day. As I'm getting older I find I don't need three meals a day, two is fine. Skipping breakfast helps make the mornings run smoother and I cut out a lot of unnecessary carbs doing that - I hardly eat any bread these days, and no processed cereals.
An I losing weight? My clothes feel looser I think. It's all been scupper we at points over the summer due to family camping trips as any routine / healthy eating goes out the window then! I'm using this time as a way of getting into the swing of it, planning full commitment when the summer holidays are finally over and 'normal' life resumes.
So summary, it works for me so far, you can't just eat anything during your 8 hour window, but it gives a great framework to eat healthily within.
