How much are you looking to lose in what time frame OP?
Attached is my journey to be healthy from 1st Jan 2018 - 30th April 2018. By the end of May I should have exceeded a 5 stone loss (start weight was 17st 8.5lb, BMI 43).
I call my diet "common sense".
I don't follow a restrictive "program", I don't pay someone £5 a week to weigh me, I don't pay to exercise. I am an intelligent woman and I know what I need to focus to lose weight. So I decided now was the time to do it.
No excuses.
I eat only fresh food, lean protein and whole grain unprocessed carbs like oats and rice. This means no sugar, no unhealthy food. I don't eat breakfast because I don't feel hungry. I eat 4-5 veg portions at lunch and 4-5 veg portions st dinner. No snacking at all.
In December I was considering weight loss surgery. I genuinely believed it was not possible for me your lose weight. I'm not dieting, this is how I will always eat from now onwards. I know I'll be well within the healthy BMI range by the end of the year.
Stop giving yourself excuses.
If you're wallowing in self pity, deal with your mental health at the same time as your physical health.
