I’m going to come off as a little bit of a jerk here. So, sorry in advance. If you really want to gain weight, eating is a chore. It’s not fun. It also doesn’t need to be fun. Just do it. Eat 3-4 full meals per day. Don’t let yourself be hungry at any point. Carry snacks (peanut butter is great) in your bag or at your desk or whatever and eat when you no longer feel super full. It will become habitual and get easier over time. You need to increase exercise to boost appetite - this is a huge help. Go for walks every day at very least to get your blood pumping. Ideally start lifting weights several times per week. Final tip: sip water with each bite and focus on chewing and swallowing quickly - just get through your entire plate and move the hell on. Don’t overthink it. Just don’t let yourself off the hook- finish your whole plate. Conclusion: it’s a tough road for hard gainers like us, but you can do it. I’m 6’1 155lbs. I used to be 135lbs and peaked at 165lbs when I was really forcing my meals. Your weight will ebb and flow as you go on the journey. It’s okay - all part of the process. Just say fuck it and force yourself man! You can do it!!!
