This is how people in the UK ate, even people on low incomes before processed foods came along. Herrings were a staple for many. So were kippers and other fish, onions, liver etc etc. This was how people ate before most people got fat. Sadly they probably did quite a bit of skipping meals/intermittent fasting when money rang out before Friday too.
On this
"So, my questions are:
- If processed carbs/sugars are responsible for weight gain, how come some people can happily eat this way and stay slim? (Not talking about exercise addicts/people who track their food)"
Whatever you eat if you eat fewer calories than you expend you don't put on weight. There are plenty of Parisians living on cigarettes, coffee and chocolate. It doesn't make you happy or healthy but some keep their weight down in those ways. Not good for them but they do.
"2) In 'The Diet Delusion' it basically said to stop eating processed foods but on here and other sites I see people counting their carb intake. Is this just a hangover from doing diets? I want to stop all this counting malarkey and just eat."
I don't count anything. I just eat normal foods or what I regard as normal (i.e not processed foods).
"3) Does anyone eat this way successfully in Britain with a young family?"
Yes, it is how most families ate until 50 y ears ago. In WWII people grew their food and bred rabbits for meat and no sugar was to be had. It is how man has eaten for millions of years. As for the cost issue many people eat much more than they should . If you don't eat out and avoid coffee bars and other places that burn through your money, it's not that expensive. Plenty of people if they are lucky enough to get an allotment grow their own veg and you can pick up veg quite cheaply. We eat a lot of raw swede for example. A roast chicken can last quite a few meals. Toddlers and babies eat what they are given so those with a young family find it easiest of anyone to have the family eat like this. It is teenagers used to junk food who are harder to change.
If you drink only tap water as I do you save a lot of money too. No tea or coffee or alcohol. Again after world war II plenty of families had only tea as coffee was too expensive and no one ever had wine as it cost too much. We forget how much we now have that is taken for granted which never used to be regarded as essential.
