low carb diet may help
Detailed Answer:
Hi, thanks for using healthcare magic
It can be difficult to lose weight, especially as you mentioned, if physical activity is limited.
The beta blockers would also slow down
weight loss because they can affect
metabolism.
There are different types of diets, at present you are using the low calorie/low fat diet.
Since this diet is not working well for you , you may want to consider the low
carbohydrate diet.This diet can be used in diabetics and non diabetics.
In fact it may lower your blood sugar levels.
Metformin is not one of the diabetic medications that causes
low blood sugar so it can be safely used in the low carbohydrate diet.
The low carbohydrate diet is based on the fact that
insulin is released in your body when you eat/drink foods with carbohydrates. Insulin not only lowers your blood sugar, it also stops the break down of fat.
This is the reason why, when persons reduce their carbohydrate intake and less insulin is released, fat starts to breakdown and weight loss occurs.
This diet is associated with faster weight loss and has what is called ' metabolic advantage' over other diets.
The low carbohydrate diet would require that you reduce your use of rice/pasta/bread/biscuits/sodas/fruit juices/potatoes.
You would use a lot of water daily.
It also involves the use of 1 to 2 cups of vegetable a day and 1 to 2 cups of leafy salads with your protein meals (either animal such as eggs/fish/meats or plant protein if you are a vegetarian)
No breading on any fried foods.
Snack every 2 to 3 hours to prevent hunger . Snacks such as nuts/cheese/eggs/meat
There are different sites that can provide information on low carb meals or provide meal plans to help you.
I hope this helps, feel free to ask any other questions
