Low-Carb Diet for Weight Loss: A Safe and Effective Approach

Question
I am a 47 years old man with 120 kg weight.  I am eating at night just canned tuna or grilled chicken with vegetables and I have noticed that I have loose weight. What is you opinion about this diet.
Thank you

Answer
It sounds like you are essentially following a low carb diet. I believe this is a safe effective way of losing weight. I would recommend that you add some low carb vegetables like:

Lettuce
cabbage
broccoli
asparagus
green beans

Hope that helps,
