Question : I am currently struggling with my weight which is causing ongoing issues with my knees, legs and energy levels. I am currently weighing 320 pounds...I am 5'9. I do not exercise due to low energy levels and pain in knee. I have not always been this size...I gained this weight over a period of 3 years...a total of 100 pounds. I have a high craving for sugar and late night snacking. I have tried phentermine and other OTC weight loss supplements also B12 injections and supplements with no visible results. Any recommendations for someone who has a struggle with weight and energy?

Brief Answer:
Weight

Detailed Answer:
Sorry to note your challenges with weight gain.

B12 injections and supplements have not been shown to have weight loss effects, although this practice is widely prevalent in USA.

When I see someone like you in my practice, I typically order the following tests in addition to a detailed physical examination:

CBC
Electrolytes
Calcium
HbA1c
Lipid profile
Liver function tests
Kidney function tests
TSH
Free T4
25 hydroxy Vitamin D
IGF1
Midnight Salivary Cortisol

The above tests look for possible causes of weight gain such as an under active thyroid. They also look for medical problems associated with excess body weight.

There are other uncommon conditions like Cushing's syndrome and Acromegaly that can cause weight gain too.
The two tests above ie IGF1 and Midnight Salivary Cortisol screen for these problems.

See if you can get to meet an endocrinologist to discuss weight related issues.

Seeing a dietitian to make an individualized diet plan is also helpful
