 [ Symptoms ] why am i gaining weight despite regular exercise and eating a healthy diet i am 59 years old i am faithful with getting regular exercise which includes strength training cardio using treadmill elyptical stair climber and i also attend group fitness classes 2 3 times per week my diet most of the time is clean meaning good basic food organic as much as possible fruits and vegetables and complex carbs i do not eat process foods i make everything from scratch [ Disease ] it looks like either you have thick mucous plugging your sinuses leading to sinus infections or sinusitis and as the sinuses drain through nose you have blocked nose also the back of nose and the ear are also connected via eustachian tube and the tube can also get blocked due to mucous this seems to be the most probable cause other can be nasal and sinus polyps so a pns view x ray and cbct test will help in confirmation of the cause as of now steroid nasal drops decongestants saline nasal irrigation and steam inhalation can help hope this helps regards
