What's the best (and fastest) way, diet, or workout to get rid of belly fat? I'm 5'3 and 185lb and most of my weight is in my belly?
The "fastest" way is not the "best" way.
I was pushing 240# last summer. I snored when sleeping; sleep quality was not good. I always knew I was a overweight (I am well over 6 ft tall), but my tall frame hid it well. Being only 5'-3", you have less places to hide it.
It takes a change in mindset and requires you to rethink how you go about eating.
1. Pick a time of day, and weigh yourself each morning. I weigh myself after my morning shower.
2. Eat less. Not a lot less, but less. Slow and steady wins the race.
3. Track your progess. (I use the Health app on my iPad).
4. Walk; lift; cycle. Get more active and less sedentary.
I didn't change my diet as much as I changed how much I ate when I did eat. I drink black coffee and water. I still eat wings and pizza, but not as often, and then not as much when I do. I still enjoy my suds.
I averaged about 1# or 2# loss per week. It took a few months to notice the improvement in sleep. By New Years, my belts ran out of notches. House guests (or people whose home I was a guest in) noticed that I no longer snored. I showed off my slimmer waistline, asking them if they wanted to inspect all the new room. (I could put my fist under my belt-line on either hip.) I broke the 200# barrier maybe three weeks ago. I probably got another 10-15 to go.
The only bad thing is that my clothes are soon to no longer fit. I am bummed that my boardies no longer fit.. But I'll gladly buy new ones for all the other improvements I've benefited from.
As far as progress goes, there were days when I lost, and days when I gained. The "daily" view of my weight looks like a stock market report, but the overall trend (when I zoom out to the month / year view scale), shows a 4-5 # loss per month. Some were better, some were worse, but the trend has been right.
Patience, and a will, are how you will succeed.
