I'm a bit late to this, but here's my honest opinion. I hope your girlfriend has fixed this problem of hers by the time I'm reading this. But by the way you described her in this, I see her as an undisciplined fatass. She is too lazy to try anything, and she's manipulative. She makes stupid excuses to hide her insecurities, and she's trying to blame it on you for no apparent reason except her inability to control herself. You need to put her on some David Goggins sh*t. Buy her his book, 'Can't hurt me' or 'Never finished'. If she can't read either, then show her some of his videos. What she needs isn't motivation or any other external source to push her to stop this behaviour, what she needs is discipline. She needs to learn to control herself, eat things she doesn't want to, and do things she doesn't want to do. Respect to you for caring for her and yourself so much, but she fails to see just how much you are doing for her. Some people wouldn't even care for another person like this. Hide those biscuits from her, what the f*ck? Don't let her eat them, or that bacon sausage crap. She is immature for leaving vegetables on her plate. She needs someone to sit her down and force them to eat that. How bad does she really want this? Something tells me she doesn't care that she is gaining weight, and she is just looking for quick sources of dopamine and instant gratification. She should do something like a dopamine detox, because clearly she only wants to do what is comfortable for her. As David Goggins one said, "Life isn't always about doing things you like to do, it's about doing things you have to do." In this case, she HAS to eat those vegetables and those fruit (who doesn't like fruit?), she HAS to do that extra physical activity, and she HAS to at least TRY. That's the most important thing that she is missing. She isn't trying. I am sorry if I came across as mean or hurtful, but to reach your goals, it's not all sunshine and rainbows or peaches and cream. Nor is it easy. And a lot of people don't like this idea, but this idea is the best method. Some people will eat their favorite foods such as McDonald's and Burger King and KFC but stay under a specific calorie limit, and still lose weight. But that's not right. Just because they may look good physically, doesn't mean they feel good. Take my brother for example. He used to be fat. But then he continued to eat the unhealthy foods he loved, but stayed under his calorie limit. He lost weight, and looked great, but there was a problem. He still wasn't eating nutritious foods, and he was still eating fatty processed foods! He didn't care at all it seemed. Whenever I proposed my idea to him, he never cared. "As long as I stay under my calorie limit, I can eat whatever I want!" As he always used to say. Do you know where he is now? He is 6 feet under the ground, he died of a heart attack 3 years ago because of his unhealthy eating habits. You need to get her to fix her dilemma or expect her to live a miserable life. The first step she needs to take is to realise that she has a problem. Sorry, not sorry, but this is what it takes. Good luck to you and your girlfriend. Goodbye, and hopefully you see this.
