The most important thing to remember in Body Race is balance. Just like in real life, really. You need to combine food and exercise to reach the target weight the game sets at the start of the level. Don't just focus on stuffing your face or lifting weights - that can have dire consequences, which we'll talk about in a moment.
Remember your goals
This doesn't just mean remembering the number you are aiming for, it also means remembering which shape you should aim for. Remember what you looked like at various other points in the game, and how much you weighed. Use visual cues from the past to try and get that perfect weight in the future.
Don't go too far
If you eat too much junk food, you will die. If you lose too much weight, you will die. Make sure you never go too far in one direction, otherwise you could run into a lot of trouble. Even if you want to gain weight, try and make sure you don't gain too much weight.
Avoid things if necessary
It is very easy to get through many obstacles in the game. Sure, sometimes the pile of food really gets in your way, but for the most part you can weave a burger and lift weights without too much trouble. If you feel like you've hit the right load, avoid picking up anything before the final level.
Is it worth watching ads for new clothes?
The clothes just add a new look to the main characters - they don't change anything about how the game is played. Since you will pick it up only by completing enough levels, you don't have to spend time watching videos. Do so if you are discouraged, but we can't imagine hopelessness so common.
