Gaining weight is essentially going to come down to being in a calorie surplus, meaning that you are consuming more calories than your body needs over time. Generally, a small increase in calories will lead to a gradual and healthy weight gain.
A few practical ways to bump up calorie intake can be to increase meal size, add in a snack, or use some higher calorie dense foods. Try to pick out just one or two things within your normal eating habits to change, and give yourself some time to adjust.
If you are struggling to gain weight, we can create your Personalized Protein blend to be high in protein, and have some extra carbs & calories to assist further. You can also try blending your protein into a smoothie as a great way to consume extra calories in your day.
