I lost almost 100lbs in 1 year. It actually wasn't very hard, and I could still eat out whenever I wanted to, didn't follow any diet plan what so ever, I just lit a fire under my ass and started eating better. Eliminating stuff 100% is hard, but everything in moderation is fine! If you usually drink 6 pops a day, and start drinking only 1 and replace it all with water, even that will do something. This is pretty much what I did. Depending on the lifestyle, it hard not to eat out, and not everything is horrible, you just have to learn whats good and bad.
- Started taking a 2 a day multi vitamin in the morning, it actually gave me 100x more energy! Ensure when buying vitamins, you buy one that requires you to take 2 a day, your body can only absorb so much then you're just wasting money on expensive pee. Go into GNC, ask about a 2 a day multi vitamin for men your age that would also help your metablosim, then find something similar at Shoppers Drug Mart (it's cheaper)
- Took mulberry root extract in the morning which helps your body metabolize sugars
- No cream in coffee, just skim milk, went from 3 sugar's to 1/2 sugar
- Black tea
- lots of water
- No Alcohol
- No Juice. If I had a craving, I would water down an enriched juice like Oasis and only allow myself 1 cup for breakfast.
- Exercised for 1 hour, 4 days a week. My program was 15 min treadmil or eliptical/15 min Pilates type stretches/15 min bike/15 min weights. Don't push yourself, even if you start off by walking, you're moving, and increase the pace each time you go, don't kill yourself, but push yourself to whats comfortable for you.
- Cut out starches, sugary, carby food
- Do not add salt to any home cooking, spices add better flavor. Anything I used to add lots of salt to, I switched to adding more pepper.
- Buffets - Only ate meats & veggies - No rice, potato, oil/cream based saucy things (went to one tonight and all I ate was crab, shrimp, grilled chicken and some sauted mushrooms)
- Don't eat after 6pm
- 5 small meals a day
- learn the difference between good and bad fats.
- I weighed myself, then got rid of my bathroom scale until my clothes started getting too big for me. Getting caught up on your number is stressful and can ruin your diet as you push yourself or starve yourself to lose it faster, when you starve yourself your body stores fat.

You can try it and if it doesn't work, you can waste your money on something else, but you don't need to spend money on any fad diet plan, you just need to educate yourself and have motivation.
