Possibly. It's really easy for anyone to lose water weight. Cutting out all those carbs from the sandwiches and a litre of pop could have triggered that. Glucose in your blood requires water for delivery to your cells. So cutting out a ton of carbs generally cuts this water out along with it.

It's generally better to have calories spread throughout the day than having fits and stops. You can lose weight more effectively by consuming more calories throughout the day than you can by eating fewer calories fewer times.

For example, there are people who have decided to lose weight. They'd be consuming 1,800 calories a day, but over two meals and maybe a snack.

Their personal trainer would get them to do more exercise but tell them to eat 2,300 calories over 5 or 6 times a day.

Their metabolism rockets and they burn fat gradually over the weeks at a rate of 1 or 2 pounds per week. It would be almost impossible for them not to burn fat as long as they kept at it.

Sometimes more is less. They key is to get your metabolism into overdrive--give your body a reason to burn fat. Simply dropping a lot of calories could easily trigger starvation mode, which causes your body to try hard to hang onto extra calories such as fat. Fat is a very effective form of long-term energy storage. Your body knows this. You have to shock it into thinking it absolutely needs this energy to fulfill the demands you put on your body. Cutting off extra calories as a source, and throwing intense exercise at your body will shock it into saying, "Holy shit, it's time to get into those fat cells or we're in trouble." It's a defense mechanism that forces your body to burn fat as an energy source to help with kinetics (exercise) and recovery [rebuilding tissue and replenishing muscle energy (instantly usable) in the form of glycogen and glucose after exercise].

Severely restricting calories triggers that other defensive mechanism: starvation. You want to stay away from that.

This is why I said your calories are too low for your size. Add up the calories of your typical diet (with all those sandwiches and beer) and shave off 500 calories to start. Throw in intense cardio 5 times per week, and 1 or 2 resistance training (even pushups, crunches, lunges, tricep dips and pullups at home will do) and there is no reason why, if you are in good health otherwise, you shouldn't burn fat gradually over time. It takes energy to burn energy. Once you get your weight down, you can reevaluate how many calories you want in your diet. A gradual reduction is easier to manage than simply cutting calories wholesale. Crash dieting has the highest chance of failure, and there are reasons for it.

Get into a health-oriented lifestyle and long-term change, and you will see results.
