YY to keeping away from any restrictive dieting, it makes you feel deprived, resentful and wanting to binge as a protest. Not sustainable and not a way to make yourself feel good.
Get thee to a gym and start doing weight. Get some personal training sessions to help you with changing your diet/ exercise technique. Even for a few months, it makes such a difference. The support and guidance gives you the head start and motivation you need to continue on this path. You can then mine YouTube, Facebook and Instagram for training programmes, exercises etc when you know how. The first few months are crucial, to see changes, to start feeling more energised/happier, to feel better about yourself.
Don’t do diets, they all fail long-term, 100% of them, people have been proven to be unable to keep off the weight they initially lost. It all piles back on and more. Lots of long term studies to that effect.
Rather put the focus on looking after yourself (not depriving or restricting), giving your body the nutrients it needs, giving yourself good quality sleep (very important for weight loss). Does a cake give you anything good, any vitamins, nutrients, fiber etc. ? No, zero stuff in there to benefit you. Do you want to put some rubbish into your cherished body? No, you are better than that, you deserve better. You CAN have a tray load of cake, but would you want to? No thanks, I am not about to trash my valued body, my feeling good, my self-esteem, my pride. Some stodgy, sugary rubbish is not worth it, put as much of it in front of me as you like. I value what I have got more.
