Topic Explanation
The forum discussion centers around a user who is 8 weeks post-surgery, having undergone an ileostomy and partial gastrectomy. The user is seeking advice on how to gain weight, as they have experienced issues with diarrhea when consuming nutritional drinks like Fortisip and Ensure.

Advice and Insights

1. Weight Gainer Supplements:
- Ensure and Fortisip are not designed for weight gain but for adding protein and supplements. Look for weight gainer supplements that provide high calories, around 2000 per drink.

2. Dietary Adjustments:
- Increase sugar intake temporarily to gain weight, though it is not a healthy long-term solution.
- Eat calorie-dense foods like pudding, ice cream, and junk food to gain weight.
- Incorporate heavy cream into various foods and drinks for added calories.
- Consider eating white rice, boiled plantains, and adding peanut butter to shakes for additional calories.

3. Solid Foods Over Liquids:
- Focus on increasing calorie intake through solid foods rather than liquids, especially given the partial gastrectomy.
- Avoid drinking during meals and wait at least 30 minutes after eating to drink liquids.
- Reduce fat intake as fats may not be properly digested without the pyloric sphincter.

4. Nutrient Absorption:
- Add fiber to the diet to thicken output and slow down digestion, allowing for better nutrient absorption.
- Consult with a dietitian to understand how the new digestive system has changed and optimize the diet accordingly.

5. Product Recommendations:
- Boost Very High Calorie drinks (530 calories, 22g protein) were recommended by some users, with strawberry flavor being preferred over chocolate.
- Muscle Milk was suggested as an effective product for weight gain.
- OWYN (Only What You Need) and Truvani powders were recommended for those with food sensitivities, offering high protein content.

6. Personal Experiences:
- Some users found success with unconventional methods like eating gummy bears.
- Eating small, frequent meals and keeping snacks readily available can help maintain a steady intake of calories.
- Drinking steamed whole milk mixed with coffee for additional calories and protein.

7. Medical and Professional Advice:
- It is crucial to consult with a dietitian, especially one experienced with IBD patients, to tailor a diet plan that accommodates the specific needs post
