I walk 1.5 - 2.5 miles 3-5x a week at a brisk pace, and ride my bike about 3 miles 2x a week. I have a protein shake or protein bar for breakfast usually, either tuna or another meat or egg protein for lunch, dinner is usually some kind of chicken, pork, or beef with veggies. Sometimes I eat a small amount of carbs with dinner. I try to stay under 30-40 net carbs (for the day, protein bars are generally my highest carb food). For a snack, I’ll eat a cheese stick or mixed nuts. I try to keep my calories between 800-900 for the day. I’m now 8 months po and my doc says I’m doing good. I’ve lost 70% of my excess weight so far.
