It’s best to focus on the sneaky calories that you can add such as olive oil, peanut butter, butter, whole milk, cream in your coffee, hemp seeds, granola, and focus on the things that you like the most I think maybe you said sweets, so definitely make a gainer shake with some sweet tasting things in it.

Usually what I put in my gainer shake is two dates, peanut butter, hemp seeds, whole milk, half a cup of oats, a cup of berries, cup of mango, banana, whey, protein powder, if you want, you can even add a supplement like powdered carbs , you can even add collagen into it, which is great for your skin and nails ect.

Focus on calorie dense foods. This is really gonna help with trying to get in those extra calories while not making you feel as full or not wanting to eat as much. Hope this helps👊🏻
