My first bit of advice would be to up your protein, it'll keep you satiated for longer periods. I'm currently training to be a Health and Nutritional Coach and I've read up a lot on Nutritional science prior to taking the course. Our bodies aren't supposed to ingest man-made produce (products containing flour, processed foods etc) so how it digests in the body boils down to how "whole" the food you're eating is. Carbs aren't bad at all and you should incorporate them into your diet, but the right carbs! Anything "white" has been bleached and stripped of all its nutrients so I try to stick to brown rice etc. I do eat a small amount of brown bread but rarely. Food is for fuel, it was only made for pleasure by the food industry to get people hooked to make money, then in come the pharmaceutical companies to mask man-made diseases with pills - again, to make money.
I try to stick to the rule of 3, 3rd protein, 3rd veggies, 3rd carbs.
Everybody is different, but for me I've found small tweaks make huge differences. Little and often is best. Start with a light breakfast to kick-start your metabolism (boiled eggs and a small amount of fruit can be a good start). I don't eat anything after my tea because the body can struggle to properly digest when you're in a rested state.
It's difficult at first when you've been used to filling on artificial foods to keep full, I've been there too! But it does get so much better! You feel less lethargic and more energised too.
I also always religiously drink 2.5 - 3 litres of water per day because it's one of the 5 life forces our bodies/organs and cells so desperately needs to keep working as it should.
Our bodies are so, so important and so it's imperative we look after them. If you delve into the contents of the foods we dare to put into our bodies, you'll be very surprised and also quite possibly grossed out 🙈.
I'm not going to sit here and pretend I'm a Saint. I like a couple of glasses of wine and a few slices of pizza more than the next person, but moderation is absolutely key! I find the 80/20 rule works best for me. If you have complete restrictions then you are going to struggle, so try to make these changes slowly.
You can do it! Best of luck 😊
