I had a hard time finding time to go to the gym so I set up a little gym in the basement. You don't have to spend fistfuls of money. Especially if you're not sure if you will stick with it. A spin bike or treadmill can be excellent for cardio, and you can generally find either at great prices from individuals who had great ambitions but couldn't live up to their New Years resolutions...
I agree with the above. Simple things like a an activity tracker and a phone app (I use myfitnesspal and fitbit) to track activities and food intake.
Learn how to eat and drink properly and you can lose weight, eat healthy, and drink alcohol. Generally speaking, it's not the beer making you fat, but the shitty foods you put in your mouth when you've had a couple drinks and start losing your wits. Learn how to count calories. Especially your macros, and balance them out so you can indulge in a beer or two. The first things that will bun are the alcohol cals. Balance out your fat and carb intake for the day to account for the alcohol, and you won't be depriving yourself. Of course moderation is usually key! As your body does need good fat and good carbs to survive in a healthy state.
I lift heavy (strength train) 3x a week with cardio 2-3x. If you don't want to spend a bunch of money, walk. Use your dumbells. There are plenty of full body workouts you can do with just dumbells, and I'm of the opinion, anything you do is better than nothing! You'd be surprised what you can do to get healthy rather quickly. If weight loss is a goal, do it slowly. Don't starve yourself. Your body can't sustain that for long.
Truth be told, weight loss is rather simple. Eat less calories than you burn. You don't need fancy drinks or powders or gimmicks.
If you want to be healthy. Lose weight and add in exercise. Neither cost a dime.
