[Obesity Discussion]

Welcome!!

Some nutritional suggestions....I would go skim milk as you're going to be consuming less calories and fat. Be careful on the rice crackers....loaded with carbs, and depending on the type of rice could be simple carbs which aren't great for you. Nuts are good but in moderation as they are very high in calories.

There's no way to predict what you're going to lose just by what you've told us. We can guestimate if we know how many calories you're going to be consuming on average each day and know what type of exercise you're doing for how long each day and how many days a week.....

Breathing exercises are worthless for weight loss. The best exercises are the ones that get your heart rate up and keep it up. Running is good, as are treadmills, elliptical machines, active sports, stationary bikes, bicycles, etc. Running is better than walking, and the longer you can keep your heart rate up the better. Situps and pushups aren't going to do much of anything for weight loss. You might gain some muscle in your arms/chest from the pushups, but that's about it...pushups and situps burn minimal calories, and if you're looking to lose weight, that's what's most important......reducing your calories in and ideally increasing your calories expended.

Confined in a cubicle there's not much you can do to lose weight or build lean muscle. Maybe use a resistance band to build some very minor muscle and increase strength.
