Recently I've been trying to gain weight and I changed from a relatively healthy diet to one where I eat whatever I want but I'm still struggling to put on any weight. I don't currently lift weights but I do train in Muay Thai which includes body weight excersises (push-ups, sit-ups, squats)
I was hoping someone could give me a few recommendations as to what foods I should be incorporating into my diet and also whether certain foods should be eaten at certain times of the day ? Also I do struggle to find time to go lifting as most free time is spent Thai boxing which I don't want sacrifice so ideally any excersises would be body weight.
Any help would be appreciated :)
