Could you give up meat?
I don't eat anything that comes from an animal and genuinely don't feel deprived. There are plant based versions of pie, quiche, cake, anything- I genuinely can't think of one thing I'm missing out on. I'm so much happier and healthier since going vegan. It's a myth that I'm restricted.
I eat 3 healthy meals and sometimes one small snack a day.
I only eat chocolate on Sundays.
I drink lots of water every day and walk everywhere (the walking is key). I also plank and run when it's not so hot. Planking is great as you can build up gradually and don't need any equipment or to leave the house.
A typical day:
Hot lemon water
Protein shake
Breakfast Porridge with banana and peanut butter or granola and yoghurt or Weetabix and fruit etc.
Snack generally only fruit
Dinner / tea ideas chickpeas curry, pizza, beans on toast, jacket potato, pasta, salad, many other things. I love tofu scramble and eat chickpeas.
I've just started intermittent fasting but only once a week as I'm already slim with a bmi of 18.7.
The above is not a 'diet' to me, it's lifelong because I enjoy it and that really is the game changer imo. It's mindset. There is no 'bandwagon' to fall off, it's just how I genuinely enjoy living. I'm teetotal.
Could you try and make small changes over time with a view to it being sustainable rather than 'going on a diet'.
