(e) see whether breathing exercises [2] help
Exercise. Any kind of exercise, from strength training to walking.
The diet-and-exercise cliche is a cliche because it effects just about everything about us. It may not be the only factor in snoring. Or even the dominant factor. But I'd bet the house it's a factor.
The doctor said it's all good, problem solved.
I went because I had a deviated septum and thought that was the cause of the snoring but he said that’s unlikely if the snoring only started recently.
Although others have mentioned losing weight, weight might be a side effect of a medical condition (e.g. type 2 diabetes) or social pressure (e.g. communal dining) which makes controlling diet and eating schedules very difficult.
Diabetes is a metabolic condition that has a strong correlation with genetics.
Think of a guitar string. It makes noise as it vibrates. As you age, your airway/soft pallet/esophagus loses tone and breathing in and out causes vibrations which you hear as a snore.
What To Do About It?
Health:
Snoring is not a medical issue but is an indicator of a future issue - sleep apnea. This is when your airway closes all the way. It is silent because no air is moving through your airway. This continues until your blood oxygen levels drop to a degree that your body wakes itself up to restore airway rigidity and oxygen flow. This is sleep apnea and can happen 10s to 100s of times an hour. This is like overclocking the computer of you and creates organ strain which most often will first manifest as unhealthy blood pressure issues or blood sugar issues.
If you are snoring, get a home sleep test and determine if you've progressed to apnea. Its cheap, fast and its medical efficacy is equivalent for testing Obstructive Sleep Apnea.

There are other kinds of rare apnea conditions but Obstructive Sleep Apnea is the vast majority of cases.
If you have sleep apnea, the leading treatment is a CPAP machine. Dental devices ( thedaybreak.com) and weight loss pills (GLP-1s) are rising in popularity. Apnimed.com is in third stage clinicals for sleep apnea pill.
While there's a low chance, visit your ENT and make sure you don't have anything swollen our outside of normal in your airway. If you are allergic to something in your home this can also cause the swelling and snoring and reducing the triggers can reduce or eliminate the snoring. Unlikely but it happens.
Reduce/Eliminate The Sound:
1. If snoring is soft pallet related, pull your jaw forward with a dental device.

2. Strengthen the soft pallet by playing a didgeridoo or buying and using daily an exciteOSA device https://www.cpap.com/products/exciteosa-starter-pack-cpap-co...
3. EPAP devices. They create back pressure when breathing, largely uncomfortable but will open the airway if you can tolerate them.
4. Positional devices or adjustable bed bases. Anything from tennis balls stitched into your shirt to Rx devices that sense your position and alert/encourage you to move positions. Largely a delaying action. If you are sleeping upright in a lazyboy or similar to sleep, it is a bigger deal than changing positions and you need to get checked out for apnea.
5. Mouth tape. This is largely a bad idea and I caution you against it. If you must, monitor your O2 levels when using it with a finger pulse ox.
