No. Untrue. The composition of muscles and fats are entirely different.

Fats are mainly lipids, while muscles are protein strands.

I think can start with realistic and doable steps.

WEEK 0
1. Cut sugary drinks entirely. Replace with flavored water i.e. Water with lemon slices if you need something flavored. Once you reach step 5, then you can choose to have 1 sugary drinks PER WEEK.
[IMMEDIATE START - MAINTAIN INDEFINITELY]

WEEK 1 - 3 BEFORE ADDITION
2. Do fasting for short periods of time. Start with fasting between 8pm - 8am.
[IMMEDIATE START - THEN CONTINUE FOR 2 WEEKS BEFORE MOVING TO NEXT STEP. MAINTAIN INDEFINITELY]

WEEK 3 - 5 BEFORE ADDITION
3. Swap your regular dinner with healthy one. If eating with family, then cut your rice by half.
[CONTINUE FOR 2 WEEKS - NEXT STEP AFTER 2 WEEKS. MAINTAIN INDEFINITELY]

WEEK 5 - 7 BEFORE ADDITION
4. Then swap your regular lunch with health one. Again, if eating with colleagues or what not, cut carbs (i.e. Rice / Noodle).
[CONTINUE FOR 2 WEEKS - NEXT STEP AFTER 2 WEEKS. MAINTAIN INDEFINITELY]

WEEK 5 ONWARDS FOR 2 WEEKS BEFORE ADDITION
5. Try to walk 8k steps a day. Then aim to increase that amount by 1k steps per 2 weeks until you can average out at 10k per day.
[CONTINUE FOR 2 WEEKS - NEXT STEP AFTER 2 WEEKS. MAINTAIN INDEFINITELY]

WEEK 7 ONWARDS FOR 2 WEEKS BEFORE FURTHER ADDITION
6. After that you can introduce more exercises such as your body can handle.
- Weight lifting, start from 5kg weights;
- Pushups, 10 reps per set, 3 sets per day;
- etc

Its hard to give proper advice without full details to be honest.

We don't know what are your other readings like i.e. Uric Acid level / other pre-existing conditions.

But fruits wise, maybe can go with higher fiber fruits like Banana / Papaya as opposed to higher sugar content like Watermelon / Grapes.

For vegetable wise, perhaps can try just overall increment to vegetable, reduction in carbs, rather than targeting specific vegetable.

No one specific vegetable will quicken the process. Like what others mention, no easy way out of this.

For myself, I replaced my lunch with boiled rolled oats and papaya / banana / occasionally add grapes if cheap.

Usually lasts me good time till dinner.

While dinner I generally go with cabbage / choy sum / broccoli / cauliflower / asparagus / celery; eat normally with 1/4 serving of rice or none; proteins consume as usual but with preference towards chicken / fish.
