Thanks for your feedback @Jgal. We try to keep the calorie counts of the meals between about 450 and 600 per serving, though some are outliers. For even a very small person with a basal metabolic rate of 1300-1600 calories per day, three meals per day around this calorie level will be sufficient to maintain bodyweight levels before the daily calorie expenditure of activity (TEA) and the daily calorie expenditure of all non-exercise activity (NEAT) is taken into account.
Are there any recipes that seemed particularly high in calories? I'd be happy to take a look at them!
Regarding low carb vegetarian, it's very difficult to eat low carb without also eating very low protein and high fat. Nearly all protein sources for vegetarians come with a generous portion of carbs. This being said, we often review our meal plans and recipes and will consider your request and see if it could be possible in the future. Thanks again for your feedback!
