How realistic is it then for you to be able to buy/get a hold of a barbell set? And if you can, what kind of timeframe would it be available?
It’s by no means the only option for training, it just happens to be a very very good option. Many programs are built around progressive lifting with barbells.

Sticking with relatively high-level ideas here; hopefully it’s not oversimplified. Besides just burning fat, you’re going to want to build muscle. Having more muscle will help you burn fat faster – more muscle means you burn more energy just sitting around, and muscle helps regulate the insulin response to foods.
Building muscle basically comes down to: provide the body a reason to build muscle (a stimulus like weight training), provide the body enough energy and building blocks (protein/amino acids), and give the body enough time to build that muscle and recovery from the training. Or, around tnation, it’s usually put as “lift more, eat more, sleep more”.
From a weight loss standpoint, you want to burn fat, not muscle. When you’re losing weight, some of that comes from water, some comes from fat, some comes from muscle (and some other places). You want to keep yourself well hydrated so that all the body processes keep working well. You also don’t want to burn any more muscle than necessary. The usual suggestion is to take in 1-2 grams of protein per pound of (lean) bodyweight when dieting down. This number is higher than the normal recommendation for gaining weight.
Besides the muscle-building side of it, you also need energy. You can get energy from carbs, fats, and protein, but you want to use as much protein for muscle. So that leaves carbs and fats. Some people have success with high fat, low carb diets; others use a different balance.
It seems that there is one mechanism that burns carbs for energy, and another that burns fats for energy. If you switch to a high-fat low-carb diet, your body will increase the fat-burning processes, and decrease its carb-burning. Which means, those same processes can be tricked into burning body fat too – not just dietary fat.
From a metabolic/energy-burning standpoint, interval training seems to be one of the best ways to do it. Many people think that they only burn energy when they’re doing cardio, but like muscle building, some of the most effective work happens AFTER you’ve done the cardio. A short high intensity bout of interval training can raise your metabolism so that you’re still burning increased energy over the course of the whole day.
I believe the studies have shown that 4 minutes of Tabata training (a form of very very high intensity interval training – suitable only for elite athletes) can increase metabolism for a full 24 hours. For more “normal” people, less intense interval training has also shown very good results.

A summed up version:
- Build muscle - progressive weight training, eating enough protein, and getting enough rest/recovery
- Keep that muscle - eat enough protein, and make sure you have enough fat/carbs for the rest of your energy
- Increase your fat-burning processes - increase dietary fat
- Raise your baseline metabolism - interval training
Now the details of exactly how you do that, well… that can get a bit more complicated.
