Something I heard earlier this week was, when you feel hungry and fancy a snack, ask yourself if you could have an apple. If the answer is "no", then maybe you're not that hungry. If it's "yes" - have the apple. It's hard to overeat apples - not so hard to overeat crisps, biscuits, cakes and so on.
Think about what you're drinking as well as what you're eating.
I don't exactly intermittent fast, but I never eat anything after dinner until breakfast the next day.
Try to prioritise sleep - lack of sleep is associated with being overweight which is thought to be because of the effect on your hormones.
Cut out as much processed food as possible. "Real food" is more filling and more nutritious. After a while, processed food of any sort starts to become steadily less attractive.
Look for Dr, Giles Yeo's video on Youtube where he explains how different foods affect our digestion and contribute to weight gain. (Dr Yeo is principal research associate at the Institute of Metabolic Science at the University of Cambridge) and one of his specialities is brain control of body weight. He would argue that a lot of advice commonly given about weight loss is misguided or just plain wrong. His advice can be summed up as:
"Eat real food, not too much, mostly plants" .
