I don't understand how anybody can be vegetarian and still be overweight, unless they have some kind of underlying medical condition
I weighed more as a vegan than I ever did as a veggie or omni, because I got really into food and cooking and eating out. I’m such a foodie and love eating and there are plenty of things you can eat on a vegan diet to gain weight (chips!?)
And to be fair, weight gain is all about taking in more calories than you expend. If you overeat by having a couple of bananas per day above the calories you need for maintenance you’ll gain.
Losing it now: down a stone in 4/5 weeks. Just simple CICO (calories in calories out). Tracking calories, eating whatever I want as long as it’s within 1200 calories per day. It can’t fail if you have the willpower to stick to the calories. And i know from experience, you will only have the willpower once you genuinely want to change and lose weight. Until you WANT to change, you won’t.
Willpower is just making a decision and then sticking to it. Knowing when you’re tested and have the opportunity to overeat that you already made the decision not to earlier on. It’s been revolutionary to think this way.
OP: nobody can lose your weight for you. Get MyFitnessPal, set your calorie goal (1200-1500 per day), stick to it. Exercise if you like but it’s not necessary for weight loss. Just create a calorie deficit. If you don’t do it, ask yourself why, you’ll probably find it’s because you don’t want it badly enough yet. Hopefully the day where you say ‘enough is enough’ will come before serious health problems as a result of being overweight.
