Gaining weight when doing insulin means 2 things.

1) you have enough insulin to metabolize the excess carbs you are eating.

2) You are eating more carbs than you need for daily energy so it is being stored as fat.

@A DiabetesTeam Member Same here. Gaining weight although I managed my best A1c yet since my 2011 October diagnosis at 6.1

I am experimenting with lighter meal portions. Tonight sauerkraut greens with spirulina and a small portion off egg noodles.

How do you calculate insulin dosage with carbs

As for not seeing results, it's important to understand that insulin timing and dosing need to be precisely matched to your meals and activities.

Weight gain can occur when starting insulin therapy. This happens because insulin helps your body use glucose more effectively, which can lead to increased energy storage. As for not seeing results, it's important to understand that insulin timing and dosing need to be precisely matched to your meals and activities.

Here are key factors that might affect your results:
• Meal timing - short-acting insulin works best when taken 30 minutes before eating
• Carbohydrate counting - insulin doses should match your carb intake
• Daily routine changes - stress, activity levels, and illness can affect insulin needs Consider working with a registered dietitian who specializes in diabetes to help fine-tune your insulin-to-carb ratios. They can help create a more effective plan that balances your medication with your diet.

Remember to monitor your blood sugar regularly and watch for signs of:
• Low blood sugar (feeling dizzy, shaky, or confused)
• High blood sugar (frequent urination, nausea)
• Injection site reactions

If you continue to have concerns about weight gain or effectiveness, discuss adjusting your dosage or timing with your healthcare team.
