Three(3) questions.
Beside diet and exercise to get a tone and fit body.

*
1 Don't use 'dizziness' as an excuse to take sugar. Malaysians consume lots of sugar daily. Even 'healthy' things like sports drinks and fruit juice is almost entirely sugar + water

2 Yes. If you get enough nutrients from your food, you don't need supplements. There's no specific names for body type. People just say bodybuilder, fitness model or (insert name) body

3 There's no such thing as 'toning'. Your abs/obliques are hidden under a layer of fat. Lose the fat and the abs will appear

Is fasting(puasa) really a way of losing weight?

law of weight loss carved in stone: calories in < calories out. If you fast for a day and eat like a polar bear afterwards, then no, you won't lose weight

Fact 1: There's no such thing as 'toning' Muscles can only atrophy and hypertrophy (get smaller/bigger). Muscles will give you shape (sexy butt, improve posture etc) but there's no frickin way you can 'shape' or 'tone' muscles

Fact 2: Building muscle mass is a good thing. Women lack testosterone to build muscle like men. Any female bodybuilder you've seen undergone superhuman training and receive hormonal treatment/supplements. My female cousin can deadlift heavier than a lot of men but she still looks very feminine and doesn't have the voice of a tenor

No, recent research suggests that fasting has a lot of negative health consequences. Better to keep eating; we evolved eating regular meals throughout the day, and if you fast the body slows the metabolism down and starts burning muscle tissue in preference over fat. So you become fatter and less muscular.

Fasting is bad? Try telling that to Martin Berkhan

Which brings us to our next myth: Eating frequent meals will speed up metabolism

The single biggest factor that determines how much calories you burn in a day is your basal metabolic rate (BMR). This is the amount of calories that you burn in 24 hours at rest. If your BMR is 1700, then you will burn 1700 calories a day even if you do nothing but rest all day without doing housework, without eating, without sitting in front of your computer watching prawn. In other words, this is the amount of calories you burn in 24 hours just being alive.

Lesson #1: You still burn a huge amount of calories throughout the day just by being alive, even if you don't eat.

Processing food does burn calories. The thermic effect of food (TEF) is the energy required for digestion, absorption, and disposal of ingested nutrients. Let's say that you eat a food that has 100 calories and it takes 20 calories to process the food, you will still end up with a surplus of 80 calories whether you eat it in a single meal (100-20=80) or 2 meals ((50-10)+(50-10)=80). If you're trying to lose weight, it would make no sense eating 100 calories just to burn off 20. Wouldn't it make more sense not to eat the 100 calories in the first place? At the end of the day it eventually comes down to calories in vs calories out

Lesson #2: Calorie-wise, there is no difference whether you eat small, frequent meals or large, spaced out ones
Lesson #3: Remember The Golden Rule: Calories in vs calories out

However eating small meals frequently can help. If you're trying to lose weight, eating frequently can stabilize blood sugar levels which will help you to suppress cravings. If you're trying to gain weight, it makes eating much more manageable. Eating 6x500 calorie meals is much easier than eating 3x1000 calorie meals. But it has nothing to do with keeping your metabolism high.

And finally, the whole eating frequently myth started out when companies started producing supplements. These companies came up with things like"You need protein every 2 hours or you'll lose muscle mass" or "Drink this shake 3 times a day to raise your metabolism and lose stomach fat". The more we consume, the more capitalists make.

Lesson #4: Companies will brainwash people to buy their products more frequently and in larger quantities
