Do you have health insurance? If so, would it cover a nutritionist?
I ask because I’ve been seeing a nutritionist that my health insurance pays for. Being a nutritionist is not an exact science though.
I had one a long time ago who I knew already a lot of what she said because I had read up on it. Dr. Atkins diet seems to fallen out of favor but if you read his book it has a lot of good science behind it. And I learned a lot about dieting from losing about 60 lbs on his diet. A lot of nutrition is just common sense i.e. eat lots of fruit and vegetables, avoid sugar and bad fat, eat lean meats for protein, eat or drink low fat dairy products. Eat only healthy carbs, etc.
Fasting may be recommended by some doctors but it really isn’t a good way to lose weight and keep it off. You might lose a few lbs by fasting but the chances are high that you will gain it back, and then some. Common sense.
Cutting down excessively on calories is not the best diet for long term weight loss either. Cutting down on calories is good within reason. You cut down too much it could be unhealthy and you will be walking around hungry all day which is not conducive to losing weight. Everybody’s physiology is different and can process food differently but just common sense will guide you to a healthy weight loss.
