Fluctuating blood sugar levels 198 to 130
by Lenise Ramsey
(Spruce Pine, NC, USA)
QUESTION: I am 52, post-menopausal, 5'2" and 200 lb. I have type 2 diabetes, fatty liver disease, and a preliminary diagnosis of early cirrhosis. I take metformin 2,000 mg daily and Victoza. Despite a low-carbohydrate diet and daily walking, I have not lost weight. Before dinner my glucose was 78 mg/dL; one hour after pork chop, instant brown rice and cauliflower it was 198 mg/dL. If it falls to 130–140 by two hours, is that spike harmful or preventing weight loss?
Quick Answer
A single one-hour reading of 198 mg/dL does not by itself explain why you are not losing weight. Glucose often peaks one to two hours after the beginning of a meal, and the usual post-meal target for many adults with diabetes is below 180 mg/dL. Brown rice is still a carbohydrate food, and instant rice may be digested fairly quickly. What matters more is whether this pattern repeats, what your two-hour value and HbA1c show, and how much carbohydrate was eaten. Because possible cirrhosis and lack of weight loss despite liraglutide are also present, your diabetes and liver treatment plans should be reviewed together.

Hi Lenise,
I would not judge your dinner or weight-loss progress from one glucose reading. I would look at the timing, rice portion, repeated pattern, HbA1c, and liver assessment.
Is 78 to 198 mg/dL a Dangerous Spike?
A premeal glucose of 78 mg/dL is slightly below the usual target of 80–130 mg/dL for many adults, but it is not hypoglycemia unless it is below 70 mg/dL. A one-hour value of 198 mg/dL is above the common post-meal goal of less than 180 mg/dL, but one isolated value is not an emergency.
Post-meal glucose should be checked one to two hours after the beginning of the meal. If you are 130–140 mg/dL at two hours and your HbA1c is at your individualized goal, that is reassuring. See blood sugar after eating and blood sugar by time of day.
Why Could Brown Rice Raise Glucose?
Brown rice contains more fiber than highly polished white rice, but it still contains starch that is digested into glucose. The response depends on the portion, rice variety, processing, cooking method, and the rest of the meal. “Low glycemic” does not mean “no glucose rise.”
Instant rice is more processed and may be digested faster than less processed grains. Try a smaller measured serving while keeping the pork and cauliflower similar, then compare the two-hour response. Review carbohydrates and glycemic index and low-glycemic-load foods.
Was the Pork Chop the Problem?
The trimmed pork chop is unlikely to explain a rapid glucose rise because protein and fat do not behave like starch. Calories still matter for weight management, but the rice is the more obvious carbohydrate source.
Can Glucose Spikes Stop Weight Loss?
Not in the simple way often described online. Weight change is influenced by total energy intake, appetite, activity, sleep, menopause, medicines, metabolic health, fluid retention, and body composition. Repeated high glucose should be treated, but one temporary rise to 198 mg/dL does not explain months without weight loss.
With possible cirrhosis, severe calorie restriction is not appropriate. People with cirrhosis can lose muscle even when body weight stays high, while fluid retention can make scale weight misleading. A hepatology dietitian can help create a safe calorie deficit while protecting muscle.
Your Liver Diagnosis Matters
Fatty liver disease is now commonly called metabolic dysfunction-associated steatotic liver disease (MASLD). If cirrhosis is confirmed, ask whether it is compensated and whether there is ascites, leg swelling, jaundice, confusion, or portal hypertension.
If you have abdominal swelling or ankle edema, part of the weight may be fluid rather than body fat. Weight loss can help obesity and metabolic liver disease, but in cirrhosis it should be supervised to avoid malnutrition and muscle loss.
Please Confirm the Victoza Dose
You wrote “125 mg of Victoza.” Please check the pen or prescription because this is not a standard liraglutide dose. Victoza is normally given as 0.6 mg, 1.2 mg, or 1.8 mg once daily. Do not change the dose yourself.
If you have had little or no weight reduction after months of liraglutide, your clinician should review the actual dose, adherence, side effects, eating pattern, liver status, and whether another evidence-based weight-management strategy is appropriate. Read diabetes medications.
What I Would Review Next
- HbA1c plus several days of fasting, premeal, and one- or two-hour post-meal readings
- The exact Victoza dose and duration of treatment
- Measured carbohydrate portions and total calorie intake
- Protein adequacy, sleep, menopause symptoms, and medicines that can promote weight gain
- Thyroid function if it has not been checked recently
- Whether cirrhosis is confirmed and whether fluid retention is affecting the scale
Record the meal, approximate carbohydrate amount, start time, premeal glucose, and one- or two-hour result. Use our blood sugar log and HbA1c guide.
A Better Meal Approach
I would not prescribe a rigid menu or mandatory snacks. Build meals around nonstarchy vegetables, an appropriate protein portion, healthy fats, and a measured amount of high-fiber carbohydrate if tolerated. Our diabetes meal plan and foods and blood sugar guide can help.
Important Safety Note
Because possible cirrhosis has been mentioned, seek prompt medical review for increasing abdominal swelling, leg edema, jaundice, black or bloody stool, vomiting blood, new confusion, severe weakness, or rapid unexplained weight change. Seek urgent diabetes care for repeated glucose around 300 mg/dL or higher, vomiting, dehydration, ketones, or difficult breathing. Treat glucose below 70 mg/dL as hypoglycemia.
Doctor’s Note
I would focus less on the 120-point difference and more on the repeated post-meal pattern. A one-hour reading of 198 mg/dL is mildly above the common target, but the two-hour value and HbA1c provide better context. More importantly, failure to lose weight despite substantial effort and liraglutide, together with possible cirrhosis, deserves coordinated review rather than further unsupervised restriction.
