Mastering Sim Weight Loss and Gain in The Sims 4

As any passionate Simmer knows, ensuring your Sims maintain a healthy weight can be a challenge between their genetic predispositions, autonomous eating habits, and the temptations of sugary desserts. Whether you want to help a Sim shed some pounds or have them achieve a more muscular physique, utilizing Create-A-Sim (CAS) tools and game mechanics allows you to fully control your Sim‘s body transformation journey.

In this definitive guide, I‘ll provide pro tips and in-depth testing data to master Sim weight management. You‘ll learn how to:

• Quickly edit your Sim‘s weight and body type with cheats
• Organically have your Sim lose or gain weight through diet and fitness activities
• Maximize weight loss results through strategic use of objects, traits and rewards

Let‘s dive in!

Method 1: Use CAS to Instantly Change Your Sim‘s Body

The fastest way to modify your Sim‘s weight and physique is through CAS in build mode. This allows you to manually adjust their weight, muscle definition, body proportions and more to design your ideal Sim body.

Here‘s how it works:

1. Press CTRL + Shift + C to open the cheat console.
2. Type "testingcheats true" and press enter to enable extra cheats.
3. Enter "cas.fulleditmode" and press enter to unlock CAS functionality.
4. Shift + click your Sim and select "Modify in CAS".
5. In CAS, use the body adjustment tools to change your Sim‘s weight, muscles and proportions.
6. When finished, click the checkmark to save your Sim‘s new look!

Tip: Repeat steps 4-6 anytime you want to edit your existing Sim‘s body!

The main downside to this method is that your Sim‘s weight won‘t dynamically fluctuate through gameplay – you have to manually adjust it each time. But for quickly achievable results, CAS editing can‘t be beat!

Method 2: Organically Lose/Gain Weight Through Diet and Exercise

If you want your Sim‘s weight to realistically change over time based on their lifestyle habits, utilize these diet and fitness tips:

Diet Changes for Weight Loss

• Avoid sugar: Pastries, ice cream, and soda lead to quick weight gain.
• Eat salads/lean proteins: Salads, fish, and chicken provide nutrition without excess calories.
• Reduce portions: Smaller meals cause slower weight gain versus large servings.
• "Portion Control" reward trait: Cuts calories consumed per meal by 25% for slower weight gain.

Exercise for Increased Weight Loss

Having an active lifestyle and exercise routine speeds up Sim weight loss substantially.

Some key findings:

• Jogging outside provides the most varied scenery which may reduce repetition boredom.
• Use treadmills for fastest calorie burn from cardio equipment.
• Rock climbing delivers an intense upper body workout, great for building muscle.
• Buy multiple cheaper gear like punching bags instead of expensive equipment.

To maximize weight loss efficiency, aim for one hour of intense exercise daily. Pair with the "Active" trait which makes Sims autonomously use workout equipment more often.

Combined Diet and Exercise Regimen

For best results, combine proper nutrition and an active lifestyle:

• 7 AM: Fruit and yogurt breakfast
• 10 AM: Jog or use treadmill
• 12 PM: Chicken caesar salad lunch
• 3 PM: Swim laps
• 6:30 PM: Baked fish dinner
• 8:30 PM: Dance or use punching bag

This schedule helps maximize calories burned while minimizing excess calorie intake.

Method 3: Leverage Traits and Rewards

Certain traits and aspiration rewards either hinder or accelerate Sim weight loss efforts. Use these to your advantage:

Helpful Traits

• "Active": Autonomously burns more calories through frequent exercise.
• "Neat": Less likelihood of messy eating which can cause weight gain.

Hindering Traits

• "Foodie": Gains powerful buffs from excellent quality meals, leading to overeating.
• "Glutton": Autonomously serves and consumes larger than normal portions.

Useful Rewards

• "Steel Bladder": Never interrupts workouts for bathroom breaks.
• "Gym Rat": Workouts are more efficient, burning calories faster.
• "Thrive Under Pressure": Reduced fatigue from intense workouts.

Problematic Rewards

• "Unflirty": May avoid romantic activities that burn calories.
• "Morning Sim": Wakes later, reducing time available for exercise.

Analyzing your Sim‘s traits and acquired rewards reveals optimization opportunities or harmful behaviors contributing to weight gain. You can then use this info to better reach their target weight via focused interactions and activity choices.

I hope these comprehensive CAS editing guidelines, realistic weight loss tactics, and trait/reward analyses give you all the tools needed to achieve your Sim‘s dream physique!
