For me personally and more recently:
High fibre, protein, ‘good fats’, and some carbs as they are needed. Very little processed or refined carbs.
Basically lots of vegetables, some meat, oily fish, some dairy (eggs,greek yoghurt, cottage cheese), a bit of fruit.
Supermarket frozen veg is a life hack. Cheap and always in the house for each meal.
Cook with spices more than sauces.
Supplement on: vitamin D, magnesium glycinate, Zinc picolinate, plant protein with a scoop of psyllium husk for fibre/ satiety
Eat well 90% of the time.
Some days I will happily drink black coffee and water till noon.
Very rarely drink now. 1-2 pints a month if I had to ball-point it.
Water: 3-4 pints a day
Sleep: 8+ hours.
Take away most weekends but I pick calorie conscious choices or budget for those treats.
Scales and knowing your foods seems to be golden for staying trim. Choosing low calorie dense foods help. I really enjoy my nutrition and don’t feel it’s limited at all. Habit becomes lifestyle I guess.
