Hey waves
Firstly, stop. Stop beating yourself up. What matters is that you want to take action. This isn't going to be a quick journey and you will slip up on the way. Accept that. If you beat yourself up, you'll feel worse and want to eat crap.
Secondly, do some small things. Dont radically change anything! Even if it's one less slice of toast. One less sugar in your coffee. Small adjustments go a long way.
Water - drink a whole glass of water before you eat your meal. And stay hydrated inbetween. This will fill you up.
Veggies most - try and start filling up on veg. I even went so far as to have spag bol sauce with the mince and everything, but replace the pasta with salad.
Exercise - 20 min walk. Makes a huge difference.
Treats - allow yourself a treat each day. Whether it's a chocolate bar or an ice cream... I have such a sweet tooth so I have to incorporate this into my eating otherwise I go nuts and eat all the chocolate.
Intermittent Fasting - ok so I can't do that 5:2 stuff I like my food too much 😂 I do 14:10. You have a 10 hour eating window. The remaining 14 hours of the day you do not eat - I sleep through most of this. The idea is that you give your digestive system a bit of a break. It can aid weight loss with minimal change in your diet. Research it a bit before you do it. I always feel alot better for doing it. First couple of days are hard discipline wise but once you get past that it's all good. You could give that a try? See if it works for you?
Other recommendations - I haven't tried this yet but try the Beachbody 2B Mindset. They do the Insanity workout programmes. They do all sorts of other ones too and they're amazing. I love them. I'm gonna try the 2B Mindset soon when I have some dollar. But that nutrition programme coined the ''Water first, veggies most" phrase.
This will take time. The longer the better in some respects - youre more likely to keep the weight off if you take your time.
Consistency is key though. I really recommend doing the small things... don't take away the stuff you enjoy. Try and have a little bit less then you get the best of both worlds.
I can't guarantee any of these will work. None of them will instantly. But I hope maybe you find something that does work. Good luck OP, you can do it!! Dig deep!!
