Yeah it's not true 100% of the time. As I said the timing and the types of food and the rest of your diet is important. You cook very healthy, I've looked all over it lol. You eat the right types of fats, the one's high in monounsaturates which the body likes to use as fuel and can readily use up for energy. You're also not eating more than 4,000kcal a day lol. The time you eat your carbs is probably very good as well. Last thing at night after dinner or at the weekends? I am making assumptions here so sorry if I am wrong
The right way to do things would to focus on the meat first as well as the starches. Stew would work very well for this, I'd avoid most Italian food unless it was made with real olive oil personally. Then at night is the right time to binge on the carbs or sugars if you want to.
The bad way would to get up, drink a glass of orange juice, have a massive bowl of porridge and syrup on top and then some eggs and bacon on the side lol. As soon as insulin is spiked and remains spiked with the combination of sugars and starches the body will not burn any fat at all! Then through the day you're eating your fats, the body won't use them for energy so will just store them- what else would it do with them? Remove the fats from the breakfast and have a light lunch and then you'd be much better off. By dinner rolling around insulin will be at a sensible level again and you can get away with some more shenanigans
This is why I am asking for the full diet plan, just to check everything is fine and there isn't fat being gained unnecessarily
Your focusing on what happens with regards to fat burning at that instant. It's like doing low intensity exercise to have a higher percentage of fat being used as fuel. Its what happens on overage over the 24 hours that matters.
I remember when first started talking about John Beardi talked about keeping carbs are fat apart. it's now been shown to be a pretty flimsy theory at best.
The nutrient timing aspect of it is going to make fuck all difference compared to what you eat on average each, day, week, month.
