What are some of your favorite ways to add more calories to your day?

I’ve been eating a no processed, no sugar , no grain diet as a means to improve my gut health. However I was recently prescribed adderall for my ADHD and I’ve lost 4 lbs in 3 days.

My intake has dropped dramatically. I still have hunger cues, but they are very far apart and I fill up fast. I’m trying to snack on almonds throughout the day, but I’d like to bulk up my meals.

For example, I make a smoothie of full fat yogurt and kefir, peanut butter, banana, strawberries, prebiotic fiber. I’d like to add more calories to this though. Lunch and dinners are usually chicken or salmon with veggies and sometimes a sweet potato. I wish I could simply “eat a double portion” but that’s not feasible for me at the moment.

Do natural “gainers” exist?? Like pea protein or something ? I just don’t want to mess up my metabolism and accidentally starve myself. The meds are otherwise incredibly beneficial to me. I’ve gone from hardly functional to actually feeling “normal” for the first time in years. I don’t want to mess up my body over it though.
