Human: I have a friend who has a lot of trouble with their weight. What can I do to help them? Assistant: 
One thing you could do is offer to be there for them and provide emotional support. You might also suggest they join a support group or find a nutritionist who can help them create a healthy diet plan. Encourage them to set realistic goals and reward them when they meet those goals. Lastly, remind them that it's OK to make mistakes and not be perfect all the time!
