Just checked out prices for protein shakes and they are expensive... so no to them
Am thinking of adding yoghurt and some tuna fish to my diet.... anything else that is cheap and protein rich??
It is a myth that you can reduce fat from one specific place. Your belly, your neck, your hips, fat has to go from all the places simultaneously. I can guarantee you if you maintain the right diet, and just do cardio, your belly fat will be gone and your six pack abs will show without any ab exercise....
We Pakistanis eat very little protein compared to what's recommended. Bodybuilders are recommended 1 g of protein per pound of body weight. You are 71 Kg, so you required 156 grams of protein.
1 egg has 6 grams of protein. 1 glass of milk has 8 grams. I don't know the rest of your diet, but you are only consuming 28 grams from 2 eggs and 2 glasses of Milk. Nowhere near the required amount. The reason they recommended protein powder is that 1 scoop of protein powder has 20-25 grams of protein. It is very convenient. But it is not absolutely necessary.
FOR LOSING BELLY FAT:
For exercise:
Here's what you should do: Go to any online calculator, put in your age, height and weight, and also include how many times you exercise to find out the number of calories your body needs. For example you need 2100 calories. Reduce 30% from this number. So you eat approximately 1500 calories everyday. Find out the calories in each item that you eat and then make sure you neither eat less, nor more than your calculated calories (in example, 1500 calories).
Next, do cardio exercise. Cycling, swimming, fast walking, jogging, running... anything that increases your heartrate to 60-80% of its maximum. Your maximum heart rate is 220 - your age. If you are 21, it's 199. So, you should do any exercise that raises your heartrate from 120 to 160 beats per minute (60 to 80 percent of maximum). And you need to have your heartrate up for at least 20 minutes. Start slowly though. Don't go crazy. First week, just do it for 10 minutes.
The cardio exercise needs to be done between 5 to 7 days every week. If you get bored by this exercise, look into High Intensity Interval Training.
For Nutrition:
Number 1 priority is that you are eating within 1400 calories. If you are not, you will NOT BURN THE BELLY FAT. Drink plenty of water. About protein: Forget it for now. You will only get confused. Just drink 2 glasses of milk and maybe 3 boiled eggs ( At least 1 without the yolk), the way you are doing right now. Once you have burned the fat, you can then start eating more and eating extra protein, which will add muscle... For now, it's gonna be fine. And don't overstudy this. Just start doing exercise and the reduction in your calories. Workout the rest of the things after that.
