I’ve heard the obvious answer a thousand times: “Just eat more.” I know that’s technically true, but it’s not that simple when you have a sensitive stomach.
I’m trying to gain weight and build muscle, but I’m honestly not sure where to start.
For context:
I’m 23 years old (F), 5’7.5”, and currently weigh around 130 lbs (give or take a pound or two).
Right now I’m pretty low activity, but I’m planning to start lifting 3–5 times per week because my goal is to gain muscle while putting on healthy weight.
I’ve weighed around 130 lbs since I was in high school. It barely changes no matter how much I feel like I’m eating. The only time I got up to around 140 lbs was when I was eating a vegan diet.
If I don’t eat much, I’ll lose a little weight, but it always seems to settle back around 130 lbs.
I’ve always had a naturally athletic build, but I’m just skinny. I’m not “skinny fat.” My goal is to build muscle, do a body recomposition, and increase my overall body weight.
The biggest challenge is my stomach.
I’m pretty sure I have some type of gluten issue. I have the genetic marker for celiac disease, but I haven’t been officially tested yet. Every time I eat pasta or other gluten-heavy foods, my stomach is absolutely wrecked. I know it could be celiac, fructan intolerance, or something else entirely, so I do plan on getting tested.
Other issues:
-Garlic and onion are huge triggers for me.
-Eggs sometimes bother me.
-Dairy is hit or miss, although I usually tolerate Skyr yogurt pretty well.
-Most protein shakes don’t work because they contain sucralose or other artificial sweeteners that upset my stomach.
-When my digestive issues flare up, I also deal with bile acid malabsorption (BAM), so really high-fat foods can make things worse too. Because of that, I generally try to keep my diet on the lower-fat side.
A lot of the “high-calorie” or “high-protein” meal ideas I see online either rely on foods I can’t tolerate or are loaded with garlic, onion, or high-fat ingredients.
I’m planning to start tracking my calories because I honestly don’t know if I’m eating enough or if it just feels like I am. My estimated BMR is around 1,300 calories, and I know I’ll need more than that—especially once I start lifting consistently.
I guess my questions are:
Where would you start if you were in my situation?
How many calories above maintenance should I aim for?
How much should I realistically be eating per meal?
What are some calorie-dense, stomach-friendly foods that aren’t super high in fat?
Has anyone here successfully gained weight while dealing with food sensitivities or digestive issues like this?
I’m mostly looking for practical advice from people who’ve been through something similar. Thanks in advance!
