if you decide to go that way you will wait until the andromeda galaxy collides with the milky way, metabolism is the key to loosing weight, fat and carbs provide fuel for your muscles so to burn the fat you need to work the muscles hard to spike up your metabolism such that your resting metabolic rate will go up allowing you to constantly burn more calories even with minimal activity or no activity through out the day.
it is of import to intake quality protein to allow for optimum recovery of the muscles making them bigger and stronger while at the same time increasing the calories needed for them to work properly resulting in fat loss and gaining more muscle

In the short term,diet might seem to be key but not in the longrun.

If you have built muscles trust me it can take a while(years) for you to gain fat without exercising unlike dieting
The advantages of exercises are just many,Once you have attained you required weight and cholestral level you can be careless with what you take once in a while.

I take soda's alcohol,nyama,pizza and my sugar,fat and cholestral level is low.If i were dieting,I would touch the above

Someone asked....

On this one I agree with @masukuma. Scientists say that the average guy is going to burn about 2000 calories daily even when just sitting down doing "nothing". That's how much energy it takes to think and to run his body functions. If he eats only 1500, the other 500 have to be sourced from the body itself i.e. by burning body fat and perhaps a bit of muscle.

Now, to burn the same calories through exercise would mean jumping rope or running for nearly an hour, no mean feat. So diet IS important, I believe - and an easier path to weigh loss. But a good combination of diet and exercise is really what you want. And I mean all round exercise, not cardio or strength training alone.

That being said, I think that unless you are a top-level athlete training for the Olympics, you are probably better off paying more attention to commonsense than to too much science. Just eat reasonably and have an active life. Look at cart-pushers for example. I bet you they know jack about what calories are, but see how trim they are.

Just telling things as it is. Those are practical guides to know when it's time.

Things to do to loose weight
1. Wachana na gari yako, leave it at home and walk. Walk kununua mkate , to your supermarket , walk with your kids, walk from town to community and etc Wachana na bus. It's healthier and you save alot. You be saving over 1000 per day.
2. Kula nyama peke yake Wachana na ugali, rice and all starch. The body uses all the protein it needs from food the rest it disposes it away unlike starch which is converted to body fat for future use.
3. Anza kupeleka mama mbio or become a night runner you will not believe how much energy you expend when doing the alakazam. Asubuhi mbele ya job usiku mbele ya Kulala na saa sita saa ile umeamuka kukunywa Maji. Kama imekataa kunywa miti ya maasai.
4. Fire the gardener and do it your self. save and build muscles. That will stop mama from oggling the gardeners cubes as yours materialize.
5.if you hire a fundi become the handy man this will probably kill you the first few days but you will learn as you save.
6.wash your car . Exercise and save.
7. If you have to spend on exercise learn to swim. This builds muscles especially the upper body and it's cheaper than the gym.

But good luck asking midro crass to dispense off their cars and buy a bicycle/walk. I tried and was stoned. As for swimming, they have all manner of excuses.
