I'm a pretty fucking underweight person (over 6 foot tall and 150 on the dot). I don't exercise much besides doing pull-ups on my door frame pull-up bar everytime I go into my kitchen, so I'm confused how I could actually lose weight while basically sitting in a chair all day
But I've heard weight gain shakes can potentially mess up your kidneys (happened to a friend of mine) and they aren't well-regulated (just kinda jampacked with all different good and bad nutrients)
Anyone know how a poor person cam gain weight?
The only thing you actually need to do is eat an excess of calories. Calorie-dense foods make this easier because you will eat more calories before feeling full.
Generally-speaking, fats are very calorie dense. Deep-fried stuff, stuff with butter (gonna plug vegan butter cause it's great) like mashed potatoes, bread and butter. Fried rice with lots of oil, anything with something like an aioli or cream sauce (gonna plug vegan options again, homemade are bomb). Already mentioned bread but it's pretty calorie dense. Pizza ticks all the boxes.
Basically I just recommend eating calorie dense foods. You can even use a calorie tracker to see how you're doing so that there are no surprises.
Also, make sure to exercise as you try to "bulk". This is a great opportunity to use the excess calories to build muscle and exercise will make the process healthier in general.
