Should I tell my girlfriend that she's been getting fat and that I want her to lose weight?

It's best to express your concerns in a caring and gentle way. It might be useful to start by talking about a healthy lifestyle and the importance of exercise and eating healthy foods. You could also explain to her that you're worried about her health and that you want her to stay fit and be healthy. But ultimately, it's her decision and her choice whether to take the advice on board or not.
