Since May, I have (very deliberately) put on ~16kg of mass, going from a BMI of 17.5 to 22.8. Started at around 2500kcal/day, currently at 3500kcal/day.

> I could not overeat to save my life

You are likely eating the wrong foods. It is _highly individual_ what kind of food can people eat in large caloric quantities. Start calorie tracking and experimenting more, you can figure this out. Some people do well with oatmeal (tastes like soggy sawdust to me), some with various nuts (peanut butter is a fitness industry staple), others make themselves milkshakes etc etc.

Progressive overload is key here, don't just expect to start eating 4000kcal/day, it is not going to happen (and would not be productive anyway).

> I cannot concentrate with a meal in my stomach

Same here. I feel like eating makes me lose about 10 IQ points, not great (though I am at a place in life where I can make this sacrifice). Maybe more sugar would be helpful here.

Thanks! Congrats on the 16kg.

I've been trying to eat more since I was 20 (am 34 now). It's been getting more difficult as I get older, especially with the onset of IBS a few years ago - now more foods and what used to be regular quantities cause my stomach to balloon.

All my experimentation has landed me on.. a mostly meat diet. Which I don't love (it's expensive, kills animals, impacts climate) but I can digest it more easily than vegetables or grains.

Oats are my everyday ~500cal first meal. If you find them unpalatable, try my recipe (it's literally my favorite thing to eat):

Combine in a jar night before and leave in fridge: 1/2 cup rolled oats, 1/2-1cup water/alt milk (amount depending on consistency you enjoy), half scoop flavorless protein powder, tbsp peanut butter, raisins, walnuts, pumpkin seeds, chia seeds, maybe 1/2 banana (if you need it to be a little sweeter).

I prepare mason jars with dry ingredients for the week, and add water to one or two every evening and put in fridge. Oat+raisin+pb combo tastes like my fav cliff bar. Banana + walnut are also amazing together.

I also recently got a vitamix and have been making vegetable smoothies midday to try and get more of them in my diet. I still cannot drink more than 500ml, else extreme fullness and bloating, but it's something. I'll add oats + avocado + protein powder to make it a meal with proper macros, but then I get to regular dinner time mostly full :)

Eating when full is a real bane for me. But there's bigger fish to fry in life, so I'll be a skinny guy.
