Alright so straight to the point my girlfriend of 7 years is finally more than me in weight. I love her but she is getting too big. Like since our 2 kids she has been thick. I've been fine with it but enough is enough. She knows i prefer petite women. And also for the ladies who are about to say im insensitive, its been 3 years since our youngest was born. My girlfriend also told me she wants to lose weight. Because she knows it is a turnoff for me someone who is 6ft 4 tall and 180lbs to make love to someone heavier than me. Im well endowed but i lose like 2 inches to insert because of her weight. she talks about how she is fat, she's getting fat, she hates herself for being thick and i try supporting her. But its very very aggravating for her to do this then turn around same day and eat a piece of cake. Cookies and ice cream cake. Like how tf u planning on losing weight if u aren't trying and if u aren't gonna try why complain about it? How can i help her stay on track with her weight without sounding like a shallow asshole?

How active and healthy is your lifestyle? If you don’t have a gym membership or do regular physical activity, I would ask if she wants to be your workout buddy to motivate each other to get healthier. If you already do have one, ask her to join you and that you would really like her as a workout partner.
For her to gain weight like this, it seems like there might be some emotional stuff or stress going on. I have no doubt that having kids causes some stress and chaos and this might be adding to her dietary preferences. I don’t know what kind of support system she has, but happier and healthier people tend to have a trustworthy friend or two, or family support, or are a part of a church or community organization. Getting good sleep also reduces an excessive appetite or cravings for sugar, so if at all possible, change the bedtime routine for ideal sleep hygiene.
Finally and most essential, ask to grocery shop with her or do the grocery shopping yourself. Sometimes I like to note what we’re out of and make a list which I strictly adhere to, meaning no impulse buys. This really helps me not only with budgeting, but controlling my surroundings for a healthier lifestyle. In this way, there is no junk food to gorge on, period. I would also do some meal planning. None of us in my house like to spend too much time making dinner, but we make many dinners with the Walmart stir fry kits with olive oil, with canned chicken added. Very healthy and it takes probably 10-15 minutes max. We might eat this 3-6 times a week. I also like to stock up on salad ingredients; makes for an easy and filling lunch.
